Please state your name for the 9 record. 10 A. Dr. Douglas W. Jacobson. 11 Q. What is your business address? 12 A. 2215 Coover Hall, Iowa State 13 University, Ames, Iowa 50011. 14 Q. Dr. Jacobson, are you yourself an 15 engineer? 16 A. Yes. 17 Q. By what body are you certified as an 18 engineer? 19 A. By no professional society. 20 Q. No professional society? Is there 21 any organization that has certified you as an 22 engineer? 23 A. No. 24 Q. Are you part of any peer regulatory 25 body? 5 1 Jacobson 2 A. I don't quite understand what you 3 mean by -- 4 Q. Are you part of any body the members 5 of which are peer-regulated? 6 A. Can you give me an example of what 7 you are -- 8 Q. A lawyer, an architect, an 9 accountant. 10 I thought an engineer had to be 11 certified by a peer-regulated body. 12 A. To be called a professional engineer 13 they do. 14 Q. So are you not a professional 15 engineer? 16 A. I do not have a PE license. 17 Q. You are the founder of the Palisade 18 Systems? 19 A. That's correct. 20 Q. What other titles do you hold within 21 that organization? 22 A. Chief technology officer. 23 Q. And are you a member of the board of 24 directors? 25 A. Yes. 6 1 Jacobson 2 Q. Are you a shareholder? 3 A. Yes. 4 Q. What percentage of the shares of that 5 company do you own? 6 A. I believe it's about 3 percent. 7 Q. Palisade Systems sells software 8 products to universities, businesses and other 9 institutions that maintain networks; is that 10 correct? 11 A. Yes. 12 Q. Do these products include products 13 which are intended to combat file sharing through -- 14 we are going to be using that term a lot. 15 Withdrawn. 16 These products include products that 17 are intended to combat peer-to-peer file sharing of 18 copyrighted works; is that correct? 19 MR. GABRIEL: Objection to form. 20 You can answer the question. 21 A. Yes. 22 Q. Is one of the reasons that these 23 organizations buy these products the avoidance of 24 lawsuits? 25 MR. GABRIEL: Objection to form. 7 1 Jacobson 2 Lack of foundation. 3 A. I don't -- since I'm not on the 4 marketing side, I really can't testify to why a 5 particular client buys the product. 6 Q. Have you been quoted in press 7 releases issued by the company as to reasons to buy 8 the product? 9 A. Yes. 10 Q. And in those press releases have you 11 stated that one of the reasons to buy the product is 12 to avoid lawsuits? 13 A. I very well could have. I do not -- 14 without seeing one of the press releases. 15 Q. Is one of the reasons to buy these 16 products to avoid copyright infringement lawsuits? 17 MR. GABRIEL: Objection to form. 18 A. That would be a reason to buy one of 19 the products. 20 Q. And have you specifically referred to 21 lawsuits by the RIAA as one of the types of lawsuits 22 that they could avoid by buying these products? 23 A. To my recollection, I have not. 24 Q. Is it true that the RIAA backs the 25 software that was co-licensed between your company 8 1 Jacobson 2 and Audible Magic? 3 MR. GABRIEL: Objection to form. 4 Lack of foundation. 5 A. I do not know what arrangement 6 Audible Magic and the RIAA have entered into. 7 Q. Are you aware that an officer of 8 Audible Magic was introduced to government officials 9 in Washington by representatives of the RIAA? 10 A. No. 11 MR. BECKERMAN: I would like to 12 mark as Defendant's 1 a press release from 13 Palisade Systems, Inc. bearing the 14 headline "Peer-to-Peer File Sharing 15 Struggles Intensify in Universities." 16 (Defendant's Exhibit 1, press release 17 from Palisade Systems, Inc. bearing the 18 headline "Peer-to-Peer File Sharing 19 Struggles Intensify in Universities," marked 20 for identification, as of this date.) 21 Q. Is this press release genuine? 22 A. It was released by the company. 23 MR. BECKERMAN: I would like to 24 mark as Exhibit 2 a one-page press release 25 of Palisade Systems, Inc. dated April 21, 9 1 Jacobson 2 2004. The headline is "Instantly Stop 3 Illegal P2P With PacketSure 3." 4 (Defendant's Exhibit 2, one-page 5 press release of Palisade Systems, Inc. 6 dated April 21, 2004, marked for 7 identification, as of this date.) 8 Q. Is this press release genuine? 9 A. Yes. It was released by the company. 10 Q. Going down to the third paragraph, 11 which purports to have a quotation from you, would 12 you tell us if that quotation is accurate? 13 A. Yes. 14 MR. BECKERMAN: I would like to 15 mark as Exhibit 3 a two-page article dated 16 April 19, 2004 by David Chappelle entitled 17 "Newest PacketHound release eliminates 18 illegal trading of copyrighted files." 19 (Defendant's Exhibit 3, two-page 20 article by David Chappelle dated April 19, 21 2004, marked for identification, as of this 22 date.) 23 Q. Who is Steven Brown? 24 A. Steven Brown, what was his title? He 25 was our marketing individual at Palisade. I don't 10 1 Jacobson 2 remember his exact title. 3 Q. Was he authorized to speak for 4 Palisade Systems to the press? 5 A. Yes. 6 Q. I direct you to the fifth paragraph 7 and ask you whether that is an accurate statement of 8 something that was said by Steven Brown. 9 MR. GABRIEL: Objection. Lack of 10 foundation. 11 A. I have no way of knowing firsthand 12 that Steven Brown said that. 13 Q. Do you agree with the statement "Some 14 P2P applications can evade certain security tools"? 15 A. Yes. 16 Q. Do you agree with the statement of 17 Mr. Chappelle contained in the third paragraph that 18 "Detecting and stopping copyrighted materials from 19 being shared illegally eliminates the liability 20 faced by organizations associated with file 21 sharing"? 22 MR. GABRIEL: Objection to form. 23 Lack of foundation. 24 A. Can you repeat the question? 25 (Record read.) 11 1 Jacobson 2 A. Since I'm not a lawyer, I'm not sure 3 I can comment on being a liability and the absolute 4 elimination of it. 5 Q. I call your attention to the ninth 6 paragraph, starting with the word "instead." 7 A. Okay. 8 Q. Do you agree with that paragraph? 9 MR. GABRIEL: Objection to form. 10 Lack of foundation. 11 A. Yes, I would agree with that. 12 MR. BECKERMAN: I would like to 13 mark as Exhibit 4 an article dated 14 April 21, 2004, of C/net News.Com., 15 entitled "New Tool Designed to Block Song 16 Swaps." 17 (Defendant's Exhibit 4, C/net 18 News.com article dated April 21, 2004, 19 marked for identification, as of this date.) 20 Q. Do you agree with the statement in 21 the second paragraph, the first paragraph that's not 22 in bold, which says that the song filtering software 23 is backed strongly by the Recording Industry 24 Association of America, RIAA? 25 MR. GABRIEL: Objection to form. 12 1 Jacobson 2 Lack of foundation. 3 A. I have no firsthand knowledge of 4 whether or not the RIAA has strongly backed Audible 5 Magic software. 6 Q. Do you have any reason to believe 7 that they have? 8 MR. GABRIEL: Object to the form. 9 A. Could you rephrase the question? 10 Q. What is the problem with the 11 question? 12 A. Restate the question and then I will 13 tell you. 14 Q. You said you had no firsthand 15 knowledge. Now I am asking you whether you have any 16 reason to believe that the RIAA did, in fact, back 17 the software strongly. 18 A. I have no firsthand knowledge that 19 they have. 20 Q. Did you ever see this article? 21 A. I don't recall seeing the article on 22 the web. 23 Q. Did you see any articles or press 24 releases saying that the RIAA backed the software 25 strongly? 13 1 Jacobson 2 A. I don't recall seeing any. 3 Q. So this is the first you've heard of 4 it? Is that your testimony? 5 MR. GABRIEL: I object to the form. 6 He said what he said. 7 A. I have no firsthand knowledge that 8 they have strongly backed -- I don't have any 9 firsthand knowledge that they strongly backed the 10 software, Audible Magic software. 11 Q. Do you have any other knowledge that 12 they backed it? 13 A. Not to my recollection. 14 Q. Going down to the second paragraph 15 that's not in bold and the sentences which purport 16 to quote you, would you tell me whether those are 17 accurate quotes. 18 A. Yeah. 19 Q. Now, going down to the fourth 20 paragraph starting with the word "during," is it 21 your testimony that you have no knowledge of RIAA 22 executives helping to guide Audible Magic CEO Vance 23 Ikezoye around federal government offices advocating 24 the song blocking technology as a tool for stopping 25 copyright infringement on file swapping networks? 14 1 Jacobson 2 MR. GABRIEL: Object to the form of 3 the question. 4 A. Could you please read the question 5 back again. 6 (Record read.) 7 A. I have no knowledge that that took 8 place. 9 Q. What is the relationship, if any, 10 between the RIAA and Palisade Systems, Inc.? 11 A. There is no relationship. 12 Q. Has Palisade Systems, Inc. had any 13 dealings with any agents of the Recording Industry 14 Association of America? 15 A. I believe that our chief operating 16 officer had discussions with the RIAA back in the 17 early 2000s. 18 MR. BECKERMAN: I would like to 19 mark as Exhibit 5 a press release from 20 ZDNet entitled "File-Swap Killer Grabs 21 Attention." 22 (Defendant's Exhibit 5, press release 23 from ZDNet entitled "File-Swap Killer Grabs 24 Attention," marked for identification, as of 25 this date.) 15 1 Jacobson 2 Q. Do you know what ZDNet is? 3 A. Yeah. 4 Q. What is ZDNet? 5 A. It is an online publication, is my 6 understanding. 7 Q. Have you ever used ZDNet for anything 8 other than reading? 9 A. Personally, not to my knowledge I 10 haven't. 11 Q. You've never downloaded any software 12 from ZDNet? 13 A. Not that I can recall. 14 Q. Have you never heard of ZDNet as a 15 source of software? 16 A. Not that I recall. 17 Q. And what is ZDNet News? 18 A. My understanding is it's an online 19 publication that I believe they send out to e-mails 20 to the subscribers. 21 Q. Have you ever had any dealings with 22 the University of Rochester? 23 A. Define the university. 24 Q. Excuse me? 25 A. I don't quite understand when you say 16 1 Jacobson 2 the university. 3 Q. Have you ever had any dealings with 4 officials of the University of Rochester? 5 A. Personally I have not, no. 6 Q. Has Palisade Systems? 7 A. Personally I have no knowledge of 8 that. 9 Q. What do you mean personally you have 10 no knowledge of that? Do you have some other kind 11 of secondhand knowledge of it? 12 A. Not that I recall, but I do not keep 13 close tabs of what the marketing or the sales force 14 does. 15 Q. Has Palisade Systems had any dealings 16 with the University of Rochester? 17 A. Not that I recall. 18 Q. Did the provost of the University of 19 Rochester attend a demonstration of the Audible 20 Magic software at RIAA headquarters in January of 21 2004? 22 A. Not that I know of, but ... 23 Q. Do you agree or disagree with the 24 statement that the RIAA has helped the company, 25 meaning Audible Magic, gain entree to official 17 1 Jacobson 2 Washington circles? 3 MR. GABRIEL: Object to form. Lack 4 of foundation. 5 A. I have no knowledge of what the RIAA 6 has done to help Audible Magic. 7 Q. Is it a fact that Audible Magic 8 entered into a cross-licensing agreement with 9 Palisade Systems, Inc.? 10 A. That's correct. 11 Q. What was the software designed to do? 12 A. What software? 13 Q. Song filtering software created by 14 Audible Magic, software that was mentioned in the 15 press releases I just showed you. 16 A. Audible Magic's software is designed 17 to examine audio data and determine if it matches a 18 database of copyrighted materials. 19 MR. BECKERMAN: Would you read back 20 the question. 21 (Record read.) 22 Q. Do you feel you have answered that 23 question? 24 A. I answered the question of what 25 Audible Magic software was designed to do. 18 1 Jacobson 2 Q. Is it song filtering software? 3 MR. GABRIEL: Object to the form. 4 A. Define what you mean by filtering. 5 Q. What is filtering? Withdrawn. 6 Is it your testimony here under oath 7 you do not know what the word "filtering" means? 8 MR. GABRIEL: Object to the form. 9 Argumentative. 10 A. The term has many different uses. 11 I'm trying to -- 12 Q. Is the audio designed by Audible 13 Magic designed for song filtering? 14 MR. GABRIEL: Object to the form. 15 Lack of foundation. 16 A. Will you repeat the question. 17 (Record read.) 18 A. I can't testify to what their design 19 team chose to design their software to do. 20 Q. So is it your testimony that you do 21 not know if this software has any application to 22 blocking song trades on peer-to-peer file sharing 23 networks? 24 MR. GABRIEL: Object to the form. 25 That's a different question. 19 1 Jacobson 2 You can answer the question. 3 A. Which application? 4 Q. The same one we've just been talking 5 about. The application designed by Audible Magic, 6 which was cross-licensed to Palisade Systems. 7 A. The Audible Magic code that was 8 licensed by Palisade does not block traffic. 9 Q. What does it do? 10 A. It identifies traffic content. 11 Q. Is it able to identify song files? 12 A. It is able to identify -- it is able 13 to identify -- 14 It is able to analyze files and 15 determine if those files match the signatures that 16 are stored in their database. 17 Q. And was it marketed by Palisade 18 Systems as something that could identify and stop 19 illegal file trades in real time without any 20 requirement for individual users to be identified? 21 A. Yes, their code coupled with our 22 code. 23 Q. And was it marketed by Palisade 24 Systems as something that could block specific 25 illegal file trades? 20 1 Jacobson 2 A. Yes. 3 Q. Now, you are the chief technology 4 officer of Palisade? 5 A. That's correct. 6 Q. So you would be knowledgeable about 7 technology work between your company and Audible 8 Magic, is that not true? 9 MR. GABRIEL: Object to the form. 10 A. Define what you mean by technology 11 work. 12 Q. Development of computer programs. 13 A. I am knowledgeable as to how our 14 software operates and how the application interfaced 15 between our software and Audible Magic software 16 operates. 17 Q. Did your company work jointly with 18 Audible Magic to develop the first network 19 appliances that identified copyrighted works on the 20 fly combined with the ability to block individual 21 trades? 22 A. Our company worked with Audible Magic 23 to develop a product to stop peer-to-peer traffic as 24 identified by Audible Magic's proprietary code. 25 Q. And you are testifying here today 21 1 Jacobson 2 that you have no idea how the RIAA reacted to this 3 work that you are doing? 4 A. That's correct. 5 Q. Have the press releases issued by 6 Palisade Systems referred to the RIAA? 7 MR. GABRIEL: I object to the form. 8 Lack of foundation. 9 A. I'm sure that some of our press 10 releases have probably mentioned the RIAA. 11 Q. In what capacity? 12 MR. GABRIEL: Same objections. 13 A. I don't recall any direct quotes out 14 of any of the press releases. 15 Q. Did you ever meet with the CEO of 16 Audible Magic? 17 A. I recall meeting him in just a short 18 meeting when he visited Palisade, but I was not part 19 of the negotiations. 20 Q. Did you discuss the software? 21 MR. GABRIEL: The question is 22 whether Dr. Jacobson talked to the CEO 23 about the software? I'm just clarifying 24 the question. 25 Q. Did you discuss the software? 22 1 Jacobson 2 MR. GABRIEL: I object to the form. 3 A. I can't recall whether I did or 4 didn't. 5 Q. Have you formed an opinion as to 6 whether Marie Lindor personally uploaded any 7 copyrighted files to anyone? 8 A. The computer whose IP address has 9 been identified as being registered to Ms. Lindor 10 has been shown to have made songs available, 11 copyrighted material available to the internet 12 community through peer-to-peer software. 13 MO MR. BECKERMAN: I move to strike the 14 answer as nonresponsive. 15 Would you read back the question. 16 (Record read.) 17 MR. GABRIEL: Is there a question 18 pending? 19 MR. BECKERMAN: Yes. I'm waiting 20 for an answer to the question. It calls 21 for a "yes" or "no" answer. 22 MR. GABRIEL: I object. It does 23 not. He answered the question. 24 MR. BECKERMAN: Are you directing 25 him not to answer the question? 23 1 Jacobson 2 MR. GABRIEL: No, no. 3 THE WITNESS: Would you repeat the 4 question. 5 (Record read.) 6 MR. GABRIEL: My objection was he 7 just answered. 8 You can answer it again. 9 A. Again, the computer registered to 10 Marie Lindor had made available songs through 11 peer-to-peer software, therefore making them 12 available. 13 MR. BECKERMAN: I am going to say 14 this once and I am not going to repeat it. 15 We are here, we have a limited 16 time. I am on page 1 of about 40 pages 17 of notes. If this kind of gamesmanship 18 is going to be continued, we will never 19 get through even a fraction of this 20 deposition and we will just have to 21 continue it. But I have no intention of 22 accepting that type of answer. 23 If that's the way you are going 24 to play this, then we will be here all 25 day. It calls for a "yes" or "no" 24 1 Jacobson 2 answer and there is no reason to be 3 playing games in answering a question 4 that was not asked. He will be asked 5 questions that may relate to what his 6 answer was, but he has not answered the 7 question that was asked of him and it 8 calls for a "yes" or "no" and I expect 9 an answer to it. 10 MR. GABRIEL: It is a nice speech, 11 Ray. The witness answered the question. 12 I object to the characterization of 13 gamesmanship. Because you don't like the 14 answer doesn't mean it is gamesmanship. 15 The witness has answered, he has his 16 opinions. And if you want to argue with 17 me or the witness, we will be here all day 18 or we will leave. 19 MR. BECKERMAN: I am going to ask 20 the question one more time and if I do not 21 get an answer to it, we will eventually 22 seek a ruling on that and we are going to 23 seek a ruling on all questions that we do 24 not receive answers to, all questions to 25 which we do not receive answers to, and 25 1 Jacobson 2 then we will have a continued deposition. 3 MR. GABRIEL: You reserve whatever 4 you want, Ray, and seek whatever rulings 5 you want. The witness answered the 6 question and I submit this is browbeating 7 the witness into trying to get the witness 8 by arguing with me. This is not serving 9 any purpose. 10 BY MR. BECKERMAN: 11 RL Q. Have you formed an opinion as to 12 whether Marie Lindor personally uploaded any 13 copyrighted files, "yes" or "no"? 14 MR. GABRIEL: Objection. Form. 15 Asked and answered twice. 16 Q. Dr. Jacobson, would you please answer 17 the question. 18 A. I have twice already answered the 19 question. 20 Q. Are you refusing to answer the 21 question? 22 MR. GABRIEL: Objection. 23 Argumentative. He answered the question. 24 MR. BECKERMAN: We will seek a 25 ruling on that. 26 1 Jacobson 2 RL Q. Have you personally formed an opinion 3 as to whether Marie Lindor personally downloaded any 4 copyrighted files? 5 A. The computer whose IP address who has 6 been identified as belonging to Marie Lindor made 7 copyrighted material available through peer-to-peer 8 software -- made the material available through 9 peer-to-peer software. 10 MR. BECKERMAN: We also will seek a 11 ruling on that and we will seek a ruling 12 on all follow-up questions which would 13 have resulted from a "yes" or "no" answer. 14 MO I move to strike the nonresponsive 15 answer that was given. 16 Q. Based upon your examination of the 17 hard drive which you examined, what evidence did you 18 find that inculpated Marie Lindor personally? 19 MR. GABRIEL: Object to the form. 20 Lack of foundation. 21 A. Would you please define the 22 second-to-last word. 23 Q. "Her"? 24 A. No, "inculpated." Would you please 25 define that for me. 27 1 Jacobson 2 Q. Do you not know what the word 3 "inculpated" means? 4 A. That's correct. 5 Q. Are you familiar with the word 6 "exculpate"? 7 A. No. 8 Q. What is your educational background? 9 A. Computer engineering. 10 Q. Well, which school did you attend? 11 Did you get a Bachelor's degree? 12 A. Yes. 13 Q. What school? 14 A. Iowa State University, science and 15 technology. 16 Q. When did you graduate? 17 A. With which degree? 18 Q. When did you get your Bachelor's 19 degree? 20 A. 1980. 21 Q. Do you have any other degrees? 22 A. I hold a Master of Science in 23 electrical engineering. 24 Q. When did you get that? 25 A. 1982. 28 1 Jacobson 2 Q. Any other degrees? 3 A. A Doctor of Philosophy, Ph.D., in 4 computer engineering. 5 Q. When was that? 6 A. 1985. 7 Q. And you are associate professor at 8 Iowa State University? 9 A. That is correct. 10 Q. And you do not know what the word 11 "exculpate" means? 12 A. That's correct. 13 Q. Based upon your examination of the 14 hard drive which you examined in this case, what 15 evidence did you find that supported or would 16 support a conclusion that Marie Lindor had 17 personally uploaded any files? 18 A. The hard drive that I examined showed 19 no evidence of any peer-to-peer software or MP3 20 music files. 21 Q. So is it correct to say that there 22 was nothing on the hard drive that tended to prove 23 that she had uploaded or downloaded anything? 24 A. There was nothing on the hard drive 25 that indicated there was any peer-to-peer software. 29 1 Jacobson 2 Q. Hypothetically, had you discovered 3 KaZaA software and song files or remnants of KaZaA 4 software or song files resembling those that had 5 appeared in a screen shot, would that have tended to 6 support a finding that she had downloaded or 7 uploaded copyrighted files? 8 A. That would have supported a claim 9 that that computer was used to make files available. 10 Q. So it would have supported a finding 11 that the computer whose hard drive you examined had 12 been used for that purpose? 13 A. Correct. 14 Q. It would not have supported a 15 finding, would it, as to whether Marie Lindor 16 herself had used those programs or files? 17 MR. GABRIEL: Object to the form. 18 Lack of foundation. 19 THE WITNESS: Please read it back. 20 (Record read.) 21 A. That's correct. 22 Q. Hypothetically, had you discovered 23 substantial deletions, would that have supported a 24 finding that there had been the use of KaZaA file 25 sharing to download or upload copyrighted files? 30 1 Jacobson 2 MR. GABRIEL: Object to the form. 3 Lack of foundation. 4 A. Had I found substantial deletions of 5 the KaZaA software and music files, that would have 6 supported it. 7 Q. Had you discovered that the hard 8 drive had been entirely reformatted would that, in 9 your view, have supported a finding that the 10 computer had been used for uploading or downloading 11 copyrighted works? 12 MR. GABRIEL: Same objections. 13 A. Had the computer been reformatted, 14 there would have been no conclusion that I could 15 have drawn as to what was on the computer prior to 16 formatting. 17 Q. Hypothetically, had you discovered 18 substantial defragmentation of the hard drive, would 19 that have supported a finding that the computer had 20 been used to upload or download copyrighted works? 21 MR. GABRIEL: Same objection. 22 A. If that's all I had found, no, that 23 would not have supported. 24 Q. So you have concluded that the hard 25 drive that you examined was not used for KaZaA file 31 1 Jacobson 2 sharing; is that correct? 3 A. That's correct, as I testified or as 4 I -- in one of my documents, yes. 5 Q. Are you aware of any evidence of 6 anything that would point to Marie Lindor personally 7 having done something as opposed to any other 8 person? 9 MR. GABRIEL: Objection to the 10 form. Lack of foundation. 11 A. I have examined evidence that shows 12 that the computer registered to the IP address 13 belonging to Marie Lindor was used to share 14 copyrighted material. 15 Q. But other than that, other than the 16 fact that the computer was used, as you say, is 17 there any evidence to show what natural person, what 18 individual was the one who actually did it? 19 A. No. 20 Q. Do you know what processes and 21 procedures MediaSentry employed? 22 A. I do not know the inner works of 23 MediaSentry processes and procedures. 24 Q. Do you know what software they used? 25 A. No. 32 1 Jacobson 2 Q. Do you know if it was well known 3 off-the-shelf software or if it was proprietary 4 software? 5 A. Again, I do not know the inner 6 workings of MediaSentry's operations. 7 Q. Do you know if their software had 8 been peer-reviewed or published or anything like 9 that? 10 A. Not that I'm aware of. 11 Q. Have you ever testified as an expert 12 in a deposition? 13 A. No. 14 Q. Have you ever testified as an expert 15 in a trial? 16 A. No. 17 Q. Have you ever testified as an expert 18 in any other type of proceeding? 19 A. I testified in front of a school 20 board. 21 Q. As an expert? 22 A. Yes. 23 Q. On what subject? 24 A. A teacher was accused of viewing 25 pornography at school. 33 1 Jacobson 2 Q. There was no judge? 3 A. No. 4 Q. There was no arbitrator or judicial 5 type of person conducting it? It was just a school 6 board? 7 A. Yes. 8 Q. Has any judge or jury ever found your 9 methodology to be unreliable? 10 A. I've never been in front of a judge, 11 so no. 12 Q. Has any judge or jury ever found your 13 methodology to be reliable? 14 A. Again, I've never been in front of a 15 judge. 16 Q. Has anyone other than the RIAA ever 17 hired you to do a forensic examination of a hard 18 drive? 19 A. Yes. 20 Q. Who? 21 A. That school board. I'm currently 22 working on a -- 23 MR. GABRIEL: Why don't you wait 24 until the ambulance passes. 25 MR. BECKERMAN: I don't think we -- 34 1 Jacobson 2 MR. GABRIEL: It may take a while. 3 MR. BECKERMAN: This is New York, 4 Richard. This isn't Denver. We could be 5 here all day. 6 MR. GABRIEL: Just try to keep your 7 voice up. 8 A. I am currently working on two 9 forensic cases that are ongoing. I've done quite a 10 bit of forensic work for law enforcement which I do 11 pro bono. 12 Q. When were you first hired to do 13 forensic work on a hard drive? 14 MR. GABRIEL: Just for 15 clarification, when you say hired, does 16 that include the pro bono work he's 17 talking about? 18 MR. BECKERMAN: Yes. 19 A. On a hard drive, probably in the late 20 '80s. 21 Q. And who was that? 22 A. The Iowa State University. I've done 23 quite a bit of forensic work helping out various 24 individuals at the university. 25 Q. What law enforcement agency hired you 35 1 Jacobson 2 to do a forensic examination of a hard drive? 3 A. Again, I did it with no compensation. 4 I do all my forensic exams for law enforcement 5 through the Iowa State University police department. 6 However, they take in cases from other 7 jurisdictions. I don't always know the jurisdiction 8 that brought the case in. 9 Q. And they have never used you as a 10 witness? 11 A. No. We never -- they've always 12 settled. 13 Q. Apart for doing things for people at 14 Iowa State University how many times have you 15 been -- and apart from the RIAA, how many hard 16 drives have you done forensic examinations of? 17 A. By outside the university, do you 18 also mean outside the Iowa State Police Department? 19 Q. No. 20 A. I maybe misunderstood the question. 21 Can you restate the question or repeat the question? 22 Q. I will restate the question. 23 Apart from your work for the RIAA and 24 your work for people at Iowa State University, how 25 many hard drives have you been hired to do a 36 1 Jacobson 2 forensic examination of? 3 A. Probably half a dozen. It's been 4 over such a long period of time. 5 Q. What software did you use? 6 A. In the latest ones I've been using 7 EnCase. 8 Q. Which edition of EnCase? 9 A. I'm using 5. 10 Q. What did you use before? 11 A. I would use various Hex editors and 12 then -- before it was -- before we had sophisticated 13 software. Sometimes I would write software to 14 recover. 15 Q. When did you start using EnCase 5? 16 A. I don't remember the date that it 17 came out. Prior to that I was using version 4. 18 Q. When did you start using that? 19 A. Probably about three years ago. 20 Q. Has anyone other than the RIAA ever 21 hired you to opine on whether a particular computer 22 had been used for uploading or downloading 23 copyrighted works? 24 A. Copyrighted works? 25 Q. Yes. 37 1 Jacobson 2 A. No. 3 Q. How long have you been using your 4 present method of determining whether a particular 5 computer has been used for uploading or downloading 6 copyrighted works? 7 A. About a year and a half. 8 Q. When did you learn your present 9 method of determining whether a particular computer 10 has been used for uploading or downloading 11 copyrighted works? Or did you develop it yourself? 12 A. Clarification. Are you talking about 13 exams on the hard drives or just the process, the 14 entire process? 15 Q. Well, you have a method, do you not? 16 A. I have a method for examining hard 17 drives and I have a method for reviewing the 18 MediaSentry material. 19 Q. So these are two different things? 20 One isn't tied into the other? 21 A. They are two different processes. 22 Q. Okay. So let's break it down. Your 23 method of -- 24 The MediaSentry materials are 25 gathered through the internet? 38 1 Jacobson 2 A. Yeah. MediaSentry gathers the 3 material through the internet. 4 Q. How did you learn your method of 5 interpreting -- withdrawn. 6 Are you able -- 7 I am having a little difficulty with 8 this conceptually. You are breaking it down into 9 two separate processes. Is it your testimony that 10 there is a way to detect whether a computer has been 11 used for uploading or downloading copyrighted works 12 without both looking at the MediaSentry material and 13 the hard drive? 14 A. Yes. 15 Q. Let's break it down, then, into two 16 separate things. 17 How did you learn your method of 18 determining from the MediaSentry materials whether a 19 particular computer has been used for uploading or 20 downloading copyrighted works? 21 A. It was a process that I developed. 22 Q. You developed it on your own? 23 A. Yes. 24 Q. How did you learn your method of 25 determining from a hard drive whether a particular 39 1 Jacobson 2 computer has been used for uploading or downloading 3 copyrighted works? 4 A. Well, the forensic examination 5 process I learned through self-study and through the 6 forensic examiner's exam. 7 Q. Now, am I correct that you were doing 8 this for law enforcement before you were a certified 9 forensic examiner? 10 A. That's correct. 11 Q. And when did you become a certified 12 forensic examiner? 13 A. September '04. 14 Q. And why did you become a certified 15 forensic examiner? 16 A. Two reasons. One is to be able to 17 better work with the law enforcement and the other 18 is to help support our university's educational 19 mission, since we teach computer forensics. 20 Q. Wouldn't a third reason be that it 21 might give you standing to testify in a court of law 22 as to your forensic examinations of hard drives? 23 A. That I would tie in with the first 24 reason, to work better with law enforcement. 25 Q. What about your private work for the 40 1 Jacobson 2 recording industry of America? 3 A. I was a certified examiner before I 4 was engaged by the recording industry. 5 Q. Isn't it a fact that you were engaged 6 by the RIAA in 2002? 7 A. It was in September '05. 8 Q. You were not doing any work for them 9 in 2002? 10 A. No. My first work for them was in 11 the fall of 2005. I can't remember my first trip to 12 Kansas City. 13 Q. And you weren't doing any work for 14 them in 2003? 15 A. No. 16 Q. And you weren't doing any work for 17 them in 2004? 18 A. I started working with the law firm 19 in the fall of 2005. 20 MR. BECKERMAN: Off the record. 21 (Discussion off the record.) 22 Q. Has your method of determining from 23 the MediaSentry materials whether a particular 24 computer has been used for uploading or downloading 25 copyrighted works been tested by any testing body? 41 1 Jacobson 2 A. Not that I have submitted. 3 Q. Do you know anyone else that is using 4 your method, other than you? 5 A. Not that I'm aware of. 6 Q. Has your method of determining 7 through the MediaSentry materials whether a 8 particular computer has been used for uploading or 9 downloading copyrighted works been subjected to any 10 form of peer review? 11 A. Not that I'm aware of. 12 Q. Has your method of determining from 13 the MediaSentry materials whether a computer has 14 been used for uploading or downloading copyrighted 15 works been published? 16 A. No. 17 Q. Is there a known rate of error for 18 your method? 19 A. No. 20 Q. Is there a potential rate of error? 21 MR. GABRIEL: Object to the form. 22 A. I guess there is always a potential 23 of an error. 24 Q. Do you know of a rate of error? 25 A. To my process, no. 42 1 Jacobson 2 Q. Are there any standards and controls 3 over what you have done? 4 A. No. 5 Q. Have your methods been generally 6 accepted in the scientific community? 7 A. The process has not been vetted 8 through the scientific community. 9 Q. Have you had communications with 10 MediaSentry? 11 A. Not that I recall. 12 Q. Have MediaSentry's methods been 13 tested by any testing body? 14 A. I don't know. 15 Q. Have MediaSentry's methods been 16 subjected to any form of peer review? 17 A. I don't know. 18 Q. Have MediaSentry's methods been 19 published? 20 A. I don't know. 21 Q. It's a fact, is it not, that 22 MediaSentry's methods are secret? 23 MR. GABRIEL: Objection of lack of 24 foundation. 25 A. I don't know. 43 1 Jacobson 2 Q. Is there a known rate of error for 3 MediaSentry's methods? 4 A. Not that I'm aware of. 5 Q. So when you evaluate the MediaSentry 6 materials you are assuming them to be accurate? 7 A. Yes. 8 Q. Is there a potential rate of error 9 for MediaSentry's methods? 10 MR. GABRIEL: Object to the form. 11 A. There is always a potential for an 12 error. 13 Q. Are there any standards and controls 14 over MediaSentry's methods? 15 A. I don't know. 16 Q. Have MediaSentry's methods been 17 generally accepted in the scientific community? 18 MR. GABRIEL: Object to the form. 19 Lack of foundation. 20 A. Not that I know of. 21 Q. Is MediaSentry peer-regulated? 22 A. Not that I know of. 23 Q. Apart from your work on RIAA 24 litigations against owners of internet access 25 accounts, have you engaged in research on 44 1 Jacobson 2 determining whether specific individual computer 3 users engaged in copyright infringement through 4 peer-to-peer file sharing? 5 MR. GABRIEL: I'm sorry. I lost 6 the question. Could you repeat it, 7 please? 8 Q. Apart from your work on the RIAA 9 cases, have you engaged in any research on methods 10 of determining whether specific individual computer 11 users engaged in copyright infringement through the 12 use of P2P file sharing? 13 A. Yes. 14 Q. And what kind of research was that? 15 A. Obviously there was some research 16 done through Palisade as part of its product rollout 17 dealing with how to identify the individuals within 18 an organization. One of my grad students also 19 worked on the project to identify users of 20 peer-to-peer software, although that was focused 21 more on child pornography than it was copyright 22 material. 23 Q. I would like to leave aside research 24 that may have been done by others. I mean to ask 25 whether you personally have engaged in research. 45 1 Jacobson 2 A. Through Palisade as part of product 3 development. 4 Q. Is that something that is research 5 which is private and proprietary? 6 A. No. The piece I did is no longer 7 used as the technology, so it's not. 8 Q. Was it ever published? 9 A. No. At the time it was proprietary 10 to Palisade. 11 Q. And now it's been replaced by other 12 methods? 13 A. Yes. 14 Q. Apart from your work on the RIAA 15 cases, have you engaged in any research on methods 16 of determining whether specific computer hard drives 17 contained evidence of copyright infringement through 18 peer-to-peer file sharing? 19 A. No. 20 Q. Do any of your three reports -- by 21 "three reports" I'm referring to the April 7th 22 initial report, the December 19th declaration that 23 you signed and the October report which you did not 24 sign. Do any of those three reports discuss the 25 possibility of any alternate explanations other than 46 1 Jacobson 2 copyright infringement? 3 MR. GABRIEL: Object to form to the 4 extent that they speak for themselves. 5 You can answer the question. 6 A. Please read the question. I didn't 7 understand. 8 (Record read.) 9 A. Alternate explanations to? 10 Q. Your conclusions. 11 A. No. 12 I'm sorry. I said, "No." 13 Q. Did any of the three reports discuss 14 any alternate explanations other than KaZaA 15 appearing on a file owned by Marie Lindor? 16 MR. GABRIEL: Object to the form. 17 They speak for themselves. 18 A. What do you mean by KaZaA appearing 19 on a file? 20 Q. I'm sorry, I misspoke. Do any of 21 your three reports discuss the possibility of any 22 alternate explanations other than KaZaA appearing on 23 a computer owned by Marie Lindor? 24 A. No. 25 Q. Are you, as we sit here, capable of 47 1 Jacobson 2 thinking of some alternate explanations? 3 A. Yes. 4 Q. Can you think of any possible 5 infirmities in MediaSentry's methods as we sit here? 6 MR. GABRIEL: Object to form and 7 foundation. I'm sorry. 8 A. I don't have an inner knowledge of 9 their methods so I... 10 Q. Can you think of any possible 11 security vulnerabilities in the computer that was in 12 Marie Lindor's apartment? 13 MR. GABRIEL: Object to form and 14 foundation. 15 A. Repeat the question. Read it back. 16 (Record read.) 17 A. I didn't examine the hard drive that 18 was given to me for security vulnerabilities, so I 19 can't attest to what vulnerabilities may have been 20 present in that hard drive. 21 Q. As we sit here, can you think of any 22 possible security vulnerabilities in the computer 23 that was in Marie Lindor's apartment? 24 MR. GABRIEL: Objection to form. 25 Lack of foundation. 48 1 Jacobson 2 A. Read that back. 3 (Record read.) 4 A. Can you read it one more time. 5 (Record read.) 6 A. I'm sure the possibility exists there 7 were security vulnerabilities. Again, I don't know 8 which ones would apply to that particular computer. 9 Q. And did your report discuss any of 10 those possible security vulnerabilities? 11 A. No. 12 Q. Did you testify at an United States 13 Senate committee in September of 2003? 14 A. Yes. 15 Q. Did you make this statement? 16 "In summer of 2000 we introduced 17 PacketHound which is designed to detect, monitor and 18 block unauthorized peer-to-peer applications." 19 A. That sounds like -- that sounds like 20 a statement I made. 21 Q. Did you make this statement? 22 "There are no effective controls 23 regarding content provided on a peer-to-peer 24 network." 25 A. Again, that sounds like a statement I 49 1 Jacobson 2 made. 3 Q. And did you make this statement? 4 "Both the provider and the requester 5 of the file are not easily detected." 6 A. Again, that sounds like a statement 7 that was in that testimony. I don't have the 8 testimony in front of me, so I ... 9 Q. Did you make this statement? 10 "These technologies are not designed 11 for the home users." 12 A. Again, that sounds like a statement 13 that was in the testimony. 14 Q. Did you make this statement? 15 "This leaves individuals on their own 16 to solve the problems of peer-to-peer networking." 17 A. Again, that sounds like a statement 18 that was in the testimony. 19 Q. Did you make this statement? 20 "Which naturally leaves us to the 21 question, what is the homeowner to do?" 22 A. Again, that sounds like something 23 that was in that testimony. 24 Q. Did you make this statement? 25 "Unlike web filtering, where certain 50 1 Jacobson 2 sites can be blocked and web access can be 3 monitored, peer-to-peer traffic cannot be filtered 4 based on its content. This leaves a home user no 5 choice but to either allow peer-to-peer activity and 6 all of its associated risks or not allow any 7 peer-to-peer applications on their machines." 8 A. Again, that sounds like what was in 9 that testimony. 10 Q. Are you familiar with Steven Gottlieb 11 of the RIAA? 12 A. I've heard the name but that's it. 13 Q. Do you agree with this statement 14 which I will represent to you he made on 15 November 15, 2004 in comments he provided to the 16 Federal Trade Commission? 17 "P2P services often configure their 18 software to share content by default. What users 19 often do not know is that they may be sharing their 20 tax records, financial records, health records, 21 business records, e-mail and other personal and 22 private material." 23 Do you agree with that statement? 24 A. Oh, I'm sorry. Yes. 25 Q. Do you agree with this statement, 51 1 Jacobson 2 which I represent to you was made by Mr. Gottlieb? 3 "As an additional matter P2P software 4 may, upon installation, automatically search a 5 user's entire hard drive for content, files that 6 users have no intention of sharing may end up being 7 offered to the entire P2P network." 8 A. Yes. 9 Q. Do you agree with this statement 10 which I represent to you was made by Mr. Gottlieb? 11 "Continued sharing of personal 12 information is hard to avoid and is facilitated by 13 confusing and complicated instructions for 14 designating shared items." 15 A. Yes. 16 Q. Do you agree with this statement also 17 made by Mr. Gottlieb? 18 "A study by Nathaniel S. Good and 19 Aaron Krekelberg at HP Laboratories showed that the 20 majority of the users were unable to tell what files 21 they were sharing and sometimes incorrectly assumed 22 they were not sharing any files when in fact they 23 were sharing all files on their hard drive. 24 MR. GABRIEL: Object to the form. 25 Lack of foundation. 52 1 Jacobson 2 A. I guess I can't quantify some, most, 3 all. I'm sorry. 4 Q. Are you familiar with the report by 5 Nathaniel Good and Aaron Krekelberg at HP 6 Laboratories? 7 A. No. 8 MR. GABRIEL: When we get to a good 9 stopping point, can we take five? It's 10 been an hour and a half. 11 MR. BECKERMAN: Sure. 12 (Recess taken.) 13 Q. Your reports state your conclusions; 14 is that correct? 15 A. Yes. 16 Q. And they state that your conclusions 17 were based upon -- 18 Withdrawn. I shouldn't lump the 19 three together. 20 The April report states that 21 conclusions were based upon the materials that had 22 been provided to you by MediaSentry plus a few other 23 documents; is that correct? 24 A. Yes. 25 Q. Does that report explain how you 53 1 Jacobson 2 formed your conclusions from those documents? 3 A. Not in any detail. 4 Q. How many reports have you issued for 5 the RIAA? 6 A. Maybe 200. I don't know, don't 7 recall the exact count. 8 MR. BECKERMAN: I would like to 9 leave a space in the record for that 10 number. 11 TO BE FURNISHED:____________________________________ 12 ____________________________________________________ 13 Q. How many of those reports concluded 14 that there was in fact downloading or uploading of 15 plaintiff's copyright files? 16 A. All of the -- yes, all of the 17 reports. 18 Q. How much time did you spend on each 19 report? 20 A. A typical report takes me about 45 21 minutes. 22 Q. And how much time did you spend on 23 the April 2006 report in this case? 24 A. Without seeing the billing records, I 25 can only guess but I think it was 45 minutes. 54 1 Jacobson 2 Q. How much time did you spend preparing 3 the unsigned October report? 4 A. That was -- not that one. 5 I'm sorry. I was pointing to 6 something on your desk. I probably shouldn't do 7 that. 8 MR. GABRIEL: After you looked at 9 the hard drive he is asking about. 10 THE WITNESS: Okay. Thank you. 11 Q. Would you like me to show you a copy? 12 A. No. I just wanted to clarify between 13 the two reports that -- 14 Again, without looking at the billing 15 records, I would say probably two to four hours. 16 Q. And how much time did you spend on 17 the December 19th declaration? 18 A. Maybe 15 minutes. 19 Q. If a hard drive had been used for 20 peer-to-peer file sharing with KaZaA, would your 21 forensic inspection have allowed you to see whether 22 a file sharing program had been downloaded or 23 installed? 24 A. If the program was present on the 25 hard drive, a forensic examination would have shown 55 1 Jacobson 2 that. 3 Q. Similarly, if the hard drive had been 4 used for peer-to-peer file sharing with KaZaA, would 5 your forensic inspection have allowed you to see 6 whether there was a shared files folder on the 7 computer? 8 A. Yes. 9 Q. And, again, if the hard drive had 10 been used for peer-to-peer file sharing with KaZaA, 11 would your forensic inspection have shown you 12 whether there were audio files or remnants, or 13 evidence thereof, of the files that MediaSentry had 14 observed? 15 A. Yes. 16 Q. Under those same circumstances, would 17 your forensic inspection have allowed you to see 18 whether a party had attempted to delete file sharing 19 programs or other files? 20 A. Yes. 21 Q. Now, a dynamic IP address is 22 allocated very often for a short period of time; is 23 that not correct? 24 A. It depends how you define "short." 25 Q. Well, you yourself used that 56 1 Jacobson 2 technology, did you not? 3 A. Yes. 4 Q. So what is the shortest it could be? 5 There is no shortest, is there? It could be for a 6 split second? 7 A. A computer can request and release. 8 Q. It could be for hours or it could be 9 for seconds or -- 10 A. It could be for days, yes. 11 Q. Would it be possible to have the same 12 dynamic IP address assigned to three people during 13 one minutes? 14 MR. GABRIEL: Object to the form. 15 A. It's possible. 16 Q. Now, the users of a peer-to-peer 17 network often think they are anonymous when they 18 distribute files. Isn't that true? 19 A. In my opinion, a lot of users feel 20 that they are anonymous. 21 Q. In your April 7th report you say that 22 in reality they can be identified using the IP 23 address. Is that not what you said in your report? 24 A. Yes, sir. 25 Q. That's not exactly true, is it? 57 1 Jacobson 2 A. I guess I'm not clear what you mean 3 by that. 4 Q. Well, it's true, is it not, that 5 there can be more than one computer operating under 6 a single IP address? 7 MR. GABRIEL: Object to the form. 8 A. As I talked about it in the report 9 with public IP addresses, in order for the internet 10 to function there can only be -- every public IP 11 address has to be globally unique within that window 12 of time. 13 Q. But there can be more than one 14 computer operating behind that IP address? 15 MR. GABRIEL: Same objection. 16 A. Every -- I don't understand what you 17 are asking. Every device connecting to the public 18 internet has to have a global unique address. 19 Q. And a device doesn't have to be a 20 computer, does it? 21 A. That's correct. 22 Q. It could be a router, correct? 23 A. Yes. 24 Q. It could be a wired router? 25 A. Yes. 58 1 Jacobson 2 Q. It could be a wireless router? 3 A. Yes. 4 Q. And if there is a firewall, under 5 most circumstances no one would know the various 6 computers or devices behind the router, would they? 7 MR. GABRIEL: Object to form. 8 A. It depends on the type of router. 9 Q. Is it possible for more than one 10 device to be operating behind a single IP address? 11 A. Yes. 12 Q. Now, when we get to the devices, some 13 of the devices are computers. Is that not correct? 14 A. Yes. 15 Q. And is it possible for a computer to 16 have more than one user? 17 A. Yes. 18 Q. So, in other words, when a person is 19 engaged in peer-to-peer file sharing, it's not the 20 person that could be identified by an IP address, is 21 it? 22 MR. GABRIEL: Object to the form. 23 Lack of foundation. 24 Q. Isn't it the MAC address that is 25 identified? 59 1 Jacobson 2 MR. GABRIEL: Object to form. 3 A. I don't understand the follow-on 4 statement. 5 Q. Do you know what a MAC address is? 6 A. Yes. 7 Q. Can a router have a MAC address? 8 A. Yes. 9 Q. If I had ten different companies 10 operating behind a router and I had a properly 11 functioning firewall or firewalls, would anybody in 12 the wide network actually know what was behind the 13 router with the properly functioning firewall? 14 MR. GABRIEL: Object to the form. 15 Lack of foundation. 16 A. It's possible to determine who is 17 behind that, so to say that there is no way to know 18 is not true. 19 Q. How could you find out? 20 A. Potentially based on the activity 21 coming out. There is lots of ways that attackers 22 could use to determine what is behind a firewall. 23 Q. But one method to identify that 24 person would not be the IP address. The IP address 25 alone would not tell you that, would it? 60 1 Jacobson 2 A. Would not tell you what? 3 Q. What individual was sharing files. 4 A. By "individual" do you mean 5 flesh-and-blood person? 6 Q. Yes. 7 A. The IP address tells you the identity 8 of the computer. 9 Q. It actually doesn't tell you the 10 identity of the computer. It tells you the identity 11 of the device. 12 A. That's correct. 13 Q. And it doesn't actually tell you the 14 identity of the device. It tells you a MAC address? 15 MR. GABRIEL: Objection to form. 16 A. IP address does not tell you a MAC 17 address. 18 Q. How could it tell you the identity of 19 the device? How would you identify a device other 20 than by a MAC address? 21 A. Every device in the public internet 22 is configured with an IP address. 23 Q. Which would link to what? 24 A. Which links to the device. 25 Q. And how do you identify the device on 61 1 Jacobson 2 the internet? 3 A. Again, every device is identified 4 through its IP address. The MAC address is only 5 valid from one local connection to another. 6 Q. What is the one thing unique about 7 each device? 8 MR. GABRIEL: Object to the form. 9 A. Unique to it or that uniquely tells 10 them apart? 11 Q. That tells them apart. 12 A. On the internet the only requirement 13 for uniqueness is the IP address. 14 Q. So when you say that in reality they 15 can be identified using the IP address, your 16 testimony is that it's not the user that can be 17 identified, it's a computer that can be identified? 18 Is that your testimony? 19 Or is your testimony that it is the 20 computer on the network device that is interfacing 21 with the wide network? 22 A. The IP address identifies the 23 computer or device that is connected to the wide -- 24 to the internet. 25 Q. And the device might be a network 62 1 Jacobson 2 card? 3 A. Generally network card doesn't have 4 an IP address. The computer is what has the IP 5 address. 6 Q. The device might be a router? 7 A. That's correct. 8 Q. In that report you said that the IP 9 address of the computer can be captured by a user 10 during a search or file transfer. Now, you don't 11 exactly mean of the computer; you mean of the 12 computer or network device, right? 13 A. In the peer-to-peer file transfer the 14 device running -- the computer running the 15 peer-to-peer software reports its IP address 16 along with -- in addition to that, the IP address of 17 the -- if it is behind a router that separates 18 public and private addresses, then the IP address of 19 the public internet will also be shown. 20 Q. But when you said that the IP address 21 of the computer offering the files for distribution 22 can be captured by a user during a search or file 23 transfer, you didn't really mean the computer. You 24 meant the computer or network device? 25 A. In order for the peer-to-peer 63 1 Jacobson 2 software to work, you have to have the identity of 3 the machine holding the music or holding the data. 4 Q. Even if it's going through a router? 5 You're saying there is more than one IP address 6 going through a router? 7 A. The peer-to-peer software will 8 present an IP address within the data payload of the 9 IP packet. 10 Q. Well, what I'm trying to understand 11 is why in your report, referring to your April 12 report, it seems to me that when you were making 13 general descriptions of the technology involved, you 14 kept saying computer or network device but then when 15 you were coming to your conclusions about the 16 defendant, then you all of a sudden started talking 17 about computers and you left out network devices. I 18 was wondering why. 19 Do you agree with that, what I am 20 saying? 21 A. Yes. 22 Q. Why did you do that? Why did you 23 stop mentioning network devices? 24 A. Because in an examination of 25 MediaSentry data, I concluded that it was a computer 64 1 Jacobson 2 at that IP address. 3 Q. And how did you come to that 4 conclusion? 5 A. Through the MediaSentry traffic 6 captures which shows the IP address of the actual 7 computer and the IP address of the packet in transit 8 across the internet, and those two IP addresses were 9 both public and both matched. 10 Q. What is the document you are 11 referring to for MediaSentry? 12 A. I think it was the download.text file 13 or download log maybe they call it. 14 Q. The log for the user? 15 A. No. 16 MR. GABRIEL: Do you want to go off 17 the record for a minute and find it? 18 MR. BECKERMAN: No. We are on the 19 record. 20 Q. The Marie system log? Lindor, Marie 21 system log? 22 A. No. That's not the system log. It 23 could be the download record. 24 Q. This one (indicating)? 25 A. Yes. 65 1 Jacobson 2 MR. BECKERMAN: I would like to 3 mark as Exhibit 6 a printout of numbered 4 pages 36 to 45. 5 (Defendant's Exhibit 6, printout of 6 numbered pages 36 to 45, marked for 7 identification, as of this date.) 8 Q. So this tells you that there was no 9 router? 10 A. This tells me that there was -- yes. 11 There was no router. 12 Q. How does it tell you that there was 13 no router? 14 A. Through the two -- 15 If you look at the second chunk down, 16 you will see the source address at the top and you 17 will see the KaZaA IP address midway through that, 18 and they match and they are both public IP 19 addresses. 20 Q. You said they match? 21 A. Uh-huh. The 141.155.57.198. 22 Q. That's the source? 23 A. And then down below you see the KaZaA 24 IP? 25 Q. Yes. 66 1 Jacobson 2 A. It's those two IP addresses. 3 Q. What does the first number indicate? 4 A. The first number of the IP address? 5 Q. Yes. 6 No. The second line of that chunk 7 that says "source." What does that indicate? 8 A. That is the source address. That is 9 where the packet came from. 10 Q. Now we go down to the next line you 11 referred to, it says "KaZaA IP." What does that 12 refer to? 13 A. That is the IP address that the KaZaA 14 software is running on, the IP address of the 15 computer that the KaZaA software is running on. 16 Q. What is the next line? 17 A. A supernode. That's the supernode 18 that KaZaA is connected to. 19 Q. So, in other words, this went in 20 directly through the supernode? So you are saying 21 this transmission went through the supernode? 22 MR. GABRIEL: Objection to form. 23 A. No. This packet just indicates 24 that -- where the supernode is that KaZaA is talking 25 to. The packet as shown by the second line is the 67 1 Jacobson 2 actual source address of the internet packet. 3 Q. What is the next line, the KaZaA IP? 4 A. Oh. 5 Q. The line down below where you say the 6 two numbers match, what is the meaning of that 7 number? 8 A. Which one? The KaZaA IP? 9 Q. You said it is the same number. 10 A. Right. 11 Q. Where it says "KaZaA IP" and there is 12 the same number. 13 A. As line 2, yes. That is the -- that 14 is the -- 15 Q. What is the significance of that 16 line? 17 MR. GABRIEL: Let him ask the 18 question and then you answer. He asked 19 what is the significance of that line. 20 A. Of the line "KaZaA IP"? 21 Q. Yes. 22 A. That is the IP address that the KaZaA 23 software is using. 24 Q. And how is that determined? 25 A. It's determined by the KaZaA software 68 1 Jacobson 2 itself. 3 Q. Why wouldn't those two numbers always 4 be the same? 5 A. In the case of a router as you 6 described earlier that has private addresses on the 7 inside, you will see those numbers be different. 8 Q. So you are saying there can be 9 different IP addresses for different devices behind 10 the router? 11 A. Yes. 12 Q. What does the presence of the 13 supernode line indicate? 14 A. It indicates the supernode, that the 15 KaZaA software is used to perform the searches. 16 Q. So does this indicate that the 17 computer that's referred to on -- whose IP address 18 is referred to on the source line and the KaZaA IP 19 line is not a supernode? 20 A. It indicates that that computer is 21 communicating with that supernode in order to do the 22 searches. 23 Q. And how did MediaSentry determine 24 these numbers? 25 A. Line 2 of that section is the address 69 1 Jacobson 2 that is carried within the data packet as it 3 traverses across the internet. The line that starts 4 "X-KaZaA-IP" is part of the data payload within that 5 packet. 6 Q. And how do you know that? Didn't you 7 say you have never communicated with MediaSentry? 8 A. That's correct. 9 Q. So how do you know that? 10 A. Because I understand how KaZaA 11 operates. 12 Q. And how did you come to understand 13 how KaZaA operates? 14 A. Through researching protocol. 15 Q. Starting when? 16 A. I can't remember the exact date I 17 started researching KaZaA. It was all part of the 18 work Palisade did in the production of PacketHound. 19 Q. Are you familiar with the Ross 20 studies of KaZaA? 21 A. Not offhand. 22 Q. You never read them? 23 A. I don't recall without seeing one. 24 MR. BECKERMAN: I would like to 25 mark as Exhibit 7 a study entitled "The 70 1 Jacobson 2 KaZaA Overlay: A Measurement Study." 3 (Defendant's Exhibit 7, study 4 entitled "The KaZaA Overlay: A Measurement 5 Study," marked for identification, as of 6 this date.) 7 Q. So have you reviewed this report at 8 any time? 9 A. Yes, I have. 10 Q. I direct your attention to Page 17 11 and I call your attention to in the middle of the 12 page a sentence that starts with the words "later 13 versions." The statement says, "Later versions 14 (KMDV 2.0+ and KaZaA-Lite) employ dynamic port 15 numbers to evade firewalls." 16 Do you agree with that statement? 17 MR. GABRIEL: Objection. Lack of 18 foundation. 19 A. Yes. 20 Q. Going down to the end of that 21 paragraph, I will read you the last sentence and ask 22 if you agree with that sentence. 23 "Since the KaZaA port numbers are 24 dynamic, it is very difficult to block KaZaA 25 connections unless a very rigid filtering policy is 71 1 Jacobson 2 employed at the firewall." Do you agree with that 3 statement? 4 MR. GABRIEL: Object to form. Lack 5 of foundation. 6 A. Yes. 7 Q. Now I refer you to the first sentence 8 of the next paragraph. 9 "The reality of today's internet is 10 that a large fraction of peers reside behind NATs." 11 Do you agree with that statement? 12 MR. GABRIEL: Object to form. Lack 13 of foundation. 14 A. I don't have any way to know what 15 fraction. 16 Q. Do you agree that NATs exist? 17 A. Yes. 18 Q. What is a NAT? 19 A. The term stands for network address 20 translator. It is a router that on one side has a 21 public IP address and on the other side maintains or 22 has a set of what I want to refer to as private or 23 sometimes inside IP addresses, which are addresses 24 that are not allowed on the public internet. 25 Q. And do you agree that the existence 72 1 Jacobson 2 of a network address translator makes it difficult 3 to detect the IP address of specific computers 4 behind the router? 5 MR. GABRIEL: Objection to form. 6 Lack of foundation. 7 A. By router do you mean network address 8 translator? 9 Q. Yes. 10 A. Yes. 11 Q. And do you agree that KaZaA has used 12 a connection reversal in order to try to overcome 13 that? 14 MR. GABRIEL: Objection to form. 15 Lack of foundation. 16 A. I agree with the definition that they 17 specify in the article. I've never heard that 18 specific term. 19 MR. BECKERMAN: I would like to 20 mark as Exhibit 8 a one-page chart. 21 (Defendant's Exhibit 8, one-page 22 chart, marked for identification, as of this 23 date.) 24 Q. Can you identify what that displays? 25 MR. GABRIEL: Object to foundation. 73 1 Jacobson 2 He didn't draft it. 3 You can answer the question. 4 A. I don't know the intent of it but it 5 shows, as it's labeled, a cable modem connected to 6 the internet. And it shows a set of IP addresses, 7 all of which are the private -- designated as parts 8 of the private IP address range. 9 Q. Going back to the study, Exhibit 7, I 10 call your attention to Page 21, a paragraph bearing 11 number 7, and I'm going to the last two sentences 12 and I am going to ask if you agree with this 13 statement. "KaZaA uses dynamic port numbers along 14 with" -- 15 A. I'm sorry. I am not finding it. 16 Q. Page 21, there is a paragraph number 17 7. 18 A. Okay. I'm sorry. 19 Q. I am asking if you agree with this 20 statement. "KaZaA uses dynamic port numbers along 21 with its hierarchical design to avoid firewall 22 blocking." 23 Do you agree with that? 24 MR. GABRIEL: Objection to form. 25 Lack of foundation. 74 1 Jacobson 2 A. I know KaZaA uses dynamic port 3 numbers. Whether that was the original design 4 intent to avoid firewalls would be a fair 5 assumption. 6 Q. The next sentence, do you agree with 7 that statement ? 8 "Furthermore, it uses connection 9 reversal to allow NATed peers to share files." 10 MR. GABRIEL: Objection to form. 11 Lack of foundation. 12 A. Yes. 13 Q. When you studied KaZaA, did you 14 familiarize yourself with the concept of pollution 15 on KaZaA? 16 A. No. 17 Q. Do you know what pollution is on 18 KaZaA? 19 A. My understanding is it is putting 20 things out into the network KaZaA that either 21 misrepresents the content or for some reason is not 22 what it says to be. 23 MR. BECKERMAN: I will mark this as 24 Exhibit 9. It is a paper entitled 25 "Pollution in P2P File Sharing Systems." 75 1 Jacobson 2 (Defendant's Exhibit 9, paper 3 entitled "Pollution in P2P File Sharing 4 Systems," marked for identification, as of 5 this date.) 6 Q. Going to the first page, the 7 right-hand column, the first full paragraph, the 8 first sentence starts with "One sabotage technique." 9 I will ask if you agree with this statement. 10 MR. GABRIEL: I'm sorry. Where are 11 you? 12 I got it. 13 Q. "One sabotage technique that is 14 particularly prevalent today is that of pollution." 15 Do you agree with that statement? 16 MR. GABRIEL: Objection to form. 17 Lack of foundation. 18 A. I don't have any knowledge that as 19 they define pollution it is prevalent on the 20 peer-to-peer systems. 21 Q. Are you aware that one of 22 MediaSentry's areas of business is pollution? 23 A. No. 24 Q. Are you aware that MediaSentry is in 25 the business of sending out decoy files? 76 1 Jacobson 2 MR. GABRIEL: Objection to form. 3 A. No. 4 MR. GABRIEL: Sorry. Belated 5 objection to the form. 6 Q. Excuse me? 7 A. No. 8 Q. I turn you to the second page, the 9 first full paragraph. About two-thirds of the way 10 down in the paragraph there is a sentence that 11 starts "We will see that." I call your attention to 12 that sentence and ask if you agree with this 13 statement. 14 "We will see that pollution is indeed 15 pervasive with more than 50 percent of the copies of 16 many popular recent songs being polluted in KaZaA 17 today." Do you agree with that? 18 MR. GABRIEL: Objection to form. 19 Lack of foundation. 20 A. I have no way of knowing if that's 21 true or false. 22 Q. So is it your testimony that you are 23 not knowledgeable about pollution? 24 MR. GABRIEL: Objection to form. 25 Q. Are you knowledgeable about 77 1 Jacobson 2 pollution? 3 A. Only to the extent that I know what 4 it is. 5 Q. And that's the sole extent of your 6 knowledge? 7 A. Yes. 8 Q. And are you familiar with the 9 distinction between content pollution and metadata 10 pollution? 11 A. I just now read their classification. 12 Q. Is it the first time you ever learned 13 of the distinction between those two terms? 14 A. Yes. 15 Q. So it would be fair to say that your 16 expertise does not extend to the nature and extent 17 and methods of pollution on KaZaA? 18 A. Yes. 19 Q. When you in your report refer to 20 analogizing an IP address to a return address and a 21 send address on a letter, would you say that analogy 22 is somewhat incorrect? 23 A. There is probably no perfect analogy 24 but it's a reasonable analogy to use for a lay 25 explanation. 78 1 Jacobson 2 Q. Is it fair to say that your postal 3 address is to your home whereas an IP address would 4 be more like an address to a timeshare that you 5 might occupy for a split second or for a minute? 6 MR. GABRIEL: Objection to form. 7 A. The IP address delivers to a device 8 or location. 9 Q. But not a person? 10 A. That's correct. 11 Q. And not for any given amount of time, 12 just as long as the internet connection stays on 13 line? 14 MR. GABRIEL: Objection to form. 15 A. Define what you mean by internet 16 connection. 17 Q. You don't know what I mean by an 18 internet connection? 19 A. There are multiple definitions. 20 Q. Why don't you give me the most common 21 meaning. 22 A. There is an application layer 23 connection which is used by individual applications 24 to communicate. 25 Q. With a dynamic IP address is the 79 1 Jacobson 2 person using it still using it after he's 3 disconnected from the internet? 4 MR. GABRIEL: Objection to form. 5 A. Depending on how they are connected, 6 the dynamic address may be dropped. 7 Q. You're saying they could end their 8 connection to the internet and still -- and the 9 dynamic IP address stays in effect and then if they 10 turn it back on, they could pick up the same exact 11 dynamic IP address? Is that your testimony? 12 MR. GABRIEL: Objection to form. 13 Lack of foundation. 14 A. If the device that issues the dynamic 15 address can detect the other device being turned 16 off, then the dynamic IP address can be released. 17 Otherwise, the dynamic address could still be 18 assigned to that device. 19 Q. Now, with a decentralized 20 peer-to-peer network, it's your statement in your 21 report that a request is sent to each neighbor and 22 each neighbor sends the request to the next neighbor 23 and so on. Did you mean that literally? 24 A. You said decentralized? 25 Q. Yes. 80 1 Jacobson 2 A. Yes. 3 Q. To neighbors? What do you mean by 4 neighbors? 5 A. The decentralized peer-to-peer 6 software referred to the peer-to-peer entities that 7 they talked directly to as neighbors. 8 Q. So you are using it figuratively to 9 describe other computers? 10 A. Yes. 11 Q. You say the semi-decentralized 12 peer-to-peer network uses a central index server. 13 Is that correct? 14 A. Yes. 15 Q. And that if one server node quits, 16 the other nodes can still function? 17 A. Yes. 18 Q. Now, when you access a screen shot, 19 are you accessing a file or are you accessing an 20 index of files? 21 A. When you query the server, what you 22 get is an index of the files. 23 Q. Now, is it your testimony that every 24 time you see a screen shot in KaZaA, you're seeing 25 files that are on a single ordinary node? 81 1 Jacobson 2 MR. GABRIEL: Objection to form. 3 A. There are many ways you can query 4 KaZaA, one of which is to ask all the files that are 5 contained on a particular machine. 6 Q. How would you frame such a query? 7 A. You frame the query with the address 8 of the machine that contains the information. 9 Q. And do you know how MediaSentry 10 queried? 11 A. I don't know the exact techniques 12 that they used. 13 Q. Now you said in your report that you 14 will demonstrate how defendant's internet account 15 and computer were used. Would you now demonstrate 16 for me how you can -- show me how you can 17 demonstrate that the defendant's computer was used? 18 A. Which line of the report are you? 19 Q. What? 20 A. Which line of the report are you 21 referring to? 22 Q. Paragraph 15. 23 A. Would you restate the question. 24 (Record read.) 25 A. Identifications through the IP 82 1 Jacobson 2 address to demonstrate which computer it is. 3 Q. No, I'm asking you to demonstrate it 4 now for me. You said, "I will testify to the 5 procedures and results obtained by MediaSentry 6 coupled with the information complied by defendant's 7 ISP to demonstrate the defendant's internet account 8 and computer were used to download and upload 9 copyrighted music from the internet using the KaZaA 10 peer-to-peer network." 11 Please demonstrate for me that 12 defendant's computer was used to download and upload 13 copyrighted music. 14 A. I can demonstrate through the 15 MediaSentry material. 16 Q. Okay. 17 A. I don't have the MediaSentry 18 material. 19 MR. BECKERMAN: We will mark as 20 Exhibit 10 a two-page printout, page 21 numbers 46 to 47. 22 (Defendant's Exhibit 10, two-page 23 printout of page numbers 46 to 47, marked 24 for identification, as of this date.) 25 MR. BECKERMAN: We will mark as 83 1 Jacobson 2 Exhibit 11 a printout, page numbers 49 to 3 187. 4 (Defendant's Exhibit 11, printout of 5 page numbers 49 to 187, marked for 6 identification, as of this date.) 7 MR. BECKERMAN: And you already 8 have Exhibit 6 and we have Exhibit 12, 9 which is a screen shot, pages 199 to 224. 10 (Defendant's Exhibit 12, printout of 11 pages 199 to 224, marked for identification, 12 as of this date.) 13 MR. BECKERMAN: And we will mark as 14 Exhibit 13 a one-page printout marked as 15 page number 48. 16 (Defendant's Exhibit 13, one-page 17 printout of page numbered 48, marked for 18 identification, as of this date.) 19 MR. BECKERMAN: And we will mark as 20 Exhibit 14 a printout of pages numbers 188 21 through 198. 22 (Defendant's Exhibit 14, printout of 23 pages numbers 188 through 198, marked for 24 identification, as of this date.) 25 Q. Now would you please demonstrate how 84 1 Jacobson 2 you can show that it's the defendant's computer that 3 was used. 4 MR. BECKERMAN: Off the record. 5 (Recess taken.) 6 Q. Please demonstrate that the 7 defendant's computer was used. 8 MR. GABRIEL: If I can ask you, if 9 you refer to an exhibit, please say what 10 the exhibit is. 11 THE WITNESS: Yes. 12 Q. Before we go into that, let me just 13 ask you something. 14 When you say "defendant's computer" 15 in your report, you're referring to the computer 16 that was accessed by MediaSentry; is that correct? 17 A. I'm referring to the -- yeah, the 18 computer with the IP address shown in Exhibit 6 that 19 we discussed earlier. 20 Q. And it's your contention that the 21 computer as to which you examined the hard drive is 22 a different computer than the one that was accessed 23 by MediaSentry; is that correct? 24 A. Yes. 25 Q. Now, going to the first computer, how 85 1 Jacobson 2 do you know that it was defendant's computer? 3 A. We don't have the Verizon information 4 in front of me. By using the subpoenaed records 5 from Verizon they show -- 6 Q. They were asked -- 7 I'm sorry. I cut you off. 8 They were asked to identify the owner 9 of an account that had used an IP address; is that 10 correct? 11 A. Yes. 12 Q. How would that tell you who owned the 13 computer? 14 A. It tells me the individual who has 15 the account that was associated with that IP 16 address; therefore, that computer at the time. 17 Q. Let's say -- not me, that would be 18 too improbable. Let's say you had a visitor at your 19 home and that visitor plugged into your internet 20 connection with his laptop. Would that make his 21 computer your computer? 22 A. Without knowing the configuration of 23 your home network, I couldn't. 24 Q. Let's say you had a wired internet 25 connection at your home, you had a cable modem and 86 1 Jacobson 2 someone was visiting who had a laptop, a friend of 3 yours or relative, and that person asked if they 4 could plug in their laptop and check their e-mail. 5 Okay? 6 Now, the IP address would show up as 7 your address, would it not? The dynamic IP address? 8 A. It depends. 9 Q. If I sent a query like the record 10 industry sent to Verizon, I would get you, right? 11 If you are the person who pays for the internet 12 access at your home. 13 A. If the ISP allows multiple devices 14 directly connected to their internet service. 15 Q. And it wouldn't have been your 16 computer, it would have been your friend's or 17 relative's computer. Correct? 18 MR. GABRIEL: Object to the form. 19 Lack of foundation. 20 A. The scenario you laid out. If the 21 ISP allowed multiple IP addresses, then it would 22 have associated an IP address with that particular 23 device. 24 Q. So when you say it was defendant's 25 computer, you don't actually have any knowledge as 87 1 Jacobson 2 to whether it was defendant's computer. All you 3 know is that the defendant's name is associated with 4 the internet access account; is that correct? 5 MR. GABRIEL: Objection to form. 6 A. I know that the -- yeah, the computer 7 associated with that user account, an IP address was 8 used. 9 Q. But you don't know whose computer it 10 actually was, do you? 11 A. No. 12 Q. But your report said it was 13 defendant's computer, so I think you will agree that 14 that's an imprecision in your report. 15 MR. GABRIEL: Objection to form. 16 Lack of foundation. Misstates the report. 17 A. The report states that I have 18 identified through the internet service provider the 19 account holder of the IP address. 20 Q. The report says that you will 21 demonstrate that it was defendant's computer that 22 was used. How can you demonstrate that the computer 23 belonged to the defendant? You don't know who it 24 belonged to. 25 MR. GABRIEL: Objection to form. 88 1 Jacobson 2 Lack of foundation. 3 Q. You are under oath. 4 A. It's my opinion that given the 5 information from MediaSentry and from Verizon, that 6 that IP address was associated with the defendant 7 and computers or at least in presence of the 8 defendant. 9 Q. There are two parts to your 10 statement. You say the defendant's internet account 11 and computer. Right now I'm not asking you about 12 the internet account. I'm asking about the 13 computer. You will agree, then, will you not, that 14 when you said computer that you don't actually know 15 if it was defendant's computer or not? 16 A. It is the computer associated with 17 the account of the defendant. 18 Q. But you don't know if it was 19 defendant's computer? 20 A. I know that the computer was 21 associated with the defendant's internet account. 22 Q. But you don't know if the defendant 23 owned it? 24 A. Nowhere is purchase information. 25 Q. And you do not know if the defendant 89 1 Jacobson 2 ever used it? 3 A. I know that the computer associated 4 with that address was used. 5 Q. Now, demonstrate how you know that 6 that computer was used to upload and download 7 copyrighted music from the internet. 8 A. Well, I know which computer through 9 Exhibit 6. That is the primary piece of evidence. 10 I know that material was downloaded 11 through Exhibit 10. I know music was made available 12 through Exhibits 10, 11, 12 and 14, and I know that 13 the music was downloaded through Exhibit 11. 14 MR. BECKERMAN: I would like to 15 mark as Exhibit 15 the undated October 16 report. 17 (Defendant's Exhibit 15, undated 18 October report, marked for identification, 19 as of this date.) 20 Q. When did you provide this report to 21 Mr. Gabriel? 22 A. October 25th. 23 Q. Why did you not sign it? 24 A. It's a draft. 25 Q. Why is it not dated? 90 1 Jacobson 2 A. It was a draft report. 3 Q. Have you ever submitted an unsigned 4 or undated draft to Mr. Gabriel before? 5 A. I could have. I don't recall. 6 Q. Have you ever submitted unsigned 7 drafts or undated drafts to anyone in Mr. Gabriel's 8 firm before? 9 A. Again, I could have. I don't recall. 10 Q. Is it your practice to submit 11 unsigned, undated drafts before submitting your 12 final reports to them? 13 A. The standard report goes in without 14 their review. 15 MR. GABRIEL: I would like the 16 record to reflect that there is a copying 17 issue in Exhibit 15. Page DJ0069 was 18 stamped "Draft." I note in the copying 19 the draft was too light to copy 20 apparently. 21 Q. Did Mr. Gabriel tell you not to issue 22 a final report, but to issue a draft instead? 23 A. Yes. 24 Q. Now, turning to Page DJ0071, 25 Paragraph 17, the second sentence, which says, "I 91 1 Jacobson 2 will testify based on the forensic examination of 3 the hard drive that was copied from the computer 4 owned by the defendant." 5 Now, are you saying there that the 6 second computer which you claim is different than 7 the first one was owned by the defendant also? 8 A. I'm lost in the second, first and -- 9 Q. It's your words. It's your 10 testimony. It's your declaration, your unsigned 11 draft which Mr. Gabriel asked you to submit to him 12 so he could have input into the final. But this was 13 your wording I assume. Right? 14 A. Yes. 15 Q. This was wording that was not fed to 16 you by Mr. Gabriel? 17 A. Correct. 18 Q. So you say the computer owned by the 19 defendant. Now you are saying that the second 20 computer was owned by the defendant. 21 A. I'm saying the hard drive that I was 22 given to examine was reported to have been owned by 23 the defendant and I examined that hard drive and 24 came up with that conclusion. 25 Q. So is it your testimony that she 92 1 Jacobson 2 owned both computers? 3 MR. GABRIEL: Objection to form. 4 A. It's my testimony that the hard drive 5 contained no evidence of KaZaA and that hard drive 6 was reported to have belonged to the computer owned 7 by the defendant. 8 Q. What basis do you have for saying 9 that the computer was owned by the defendant? 10 A. Based on the chain of evidence 11 that -- the chain of custody that followed the 12 forensic disk. 13 Q. So it is your testimony that Marie 14 Lindor, who is a home health aide who has never even 15 used a computer, it is your testimony that she owns 16 two computers? 17 MR. GABRIEL: Objection to form. 18 Lack of foundation. Misstates testimony. 19 Q. Is that your testimony? She has 20 never even used a computer in her life, that she 21 owns not one, but two computers? 22 MR. GABRIEL: Same objection. 23 A. What I am stating is that the hard 24 drive I examined, which was reported to have come -- 25 been owned by the defendant did not contain KaZaA or 93 1 Jacobson 2 any of the copyrighted or any music files. 3 MR. BECKERMAN: Let's mark as 4 Exhibit 16 your April report. 5 (Defendant's Exhibit 16, Dr. Douglas 6 W. Jacobson's April report, marked for 7 identification, as of this date.) 8 Q. Now, on Page DJ0006, Paragraph 19, in 9 the last line you use the words "being distributed." 10 A. Yes. 11 Q. Were you using "distributed" in the 12 legal sense of the word or in the generic sense of 13 the word? 14 MR. GABRIEL: Objection to form. 15 A. I'm not a lawyer so I don't know the 16 legal -- I guess I am not clear as to what 17 difference you are trying to make between the two 18 words. 19 Q. Where did you get the word 20 "distributed"? 21 A. In that paragraph I'm referring to 22 the fact that the files were on the peer-to-peer 23 network and by the nature of the peer-to-peer 24 network they are being distributed. 25 Q. Do you know of any instances in which 94 1 Jacobson 2 they were distributed to anyone other than 3 MediaSentry? 4 A. Given the nature of the peer-to-peer 5 system, there is a high probability that they 6 were -- well, strike that. 7 Distributed, they are being offered 8 for distribution by the fact that they were on the 9 peer-to-peer network. 10 Q. The question was whether they had 11 actually been distributed, not whether they had been 12 offered for distribution. 13 MR. GABRIEL: Objection to form. 14 A. The KaZaA program made those files 15 available through the supernode. Anybody -- 16 Let me strike that and start over. 17 The KaZaA program made the files 18 available on her computer for distribution and given 19 the nature of the peer-to-peer network and the 20 number of users, there is a high probability that 21 songs were actually uploaded from that computer. 22 Q. Do you have any knowledge of any 23 specific instances of any uploads other than to 24 MediaSentry? 25 A. No. 95 1 Jacobson 2 Q. In Paragraph 21 you use the words 3 that the computer was registered to the defendant. 4 How does a computer get registered to a person? 5 A. Through the IP address it is 6 registered. Verizon indicated the subscriber. 7 Q. So you don't mean that the computer 8 was registered to the defendant. You mean the IP 9 address was identified by Verizon as having been on 10 the internet access account that was in the name of 11 the defendant. Is that correct? 12 A. The IP address of, was registered to 13 the defendant on said computer. So it says that the 14 IP address. 15 Q. Not the computer. The IP address was 16 registered? 17 A. That's what 21 states. 18 Q. 21 states that the computer that had 19 the IP address was registered to the defendant. 20 "I will testify based on all of the 21 information" -- 22 A. Right, right. 23 Q. So you don't mean the computer was 24 registered, you mean the IP address was registered? 25 A. Yes. 96 1 Jacobson 2 Q. Now, in Paragraph 22 you state that 3 you could prove from the MediaSentry user log that 4 the music found on the defendant's computer was 5 downloaded from other users on the internet. How 6 would you have done that? 7 A. By using the metadata tags, in 8 particular the description tag. For example, 9 Page 0106. 10 MR. GABRIEL: What exhibit? 11 THE WITNESS: I'm sorry. 12 Exhibit 11. 13 A. Page 10106 indicates in the 14 description "ripped by" and had several -- several 15 cases "ripped by X7" and so on, and that's 16 throughout the document. 17 Q. A metadata is text, is it not? 18 A. Yes. 19 Q. Metadata can be changed, can it not? 20 A. Metadata can be changed and is not 21 present on original CD recordings. 22 Q. And it can be changed easily through 23 commonly available software, can it not? 24 A. Yes. 25 Q. And could it be changed through KaZaA 97 1 Jacobson 2 software? 3 A. Yeah. I believe KaZaA lets you edit 4 the metadata. 5 MR. BECKERMAN: I would like to 6 mark as Exhibit 17 a page of handwritten 7 notes. 8 (Defendant's Exhibit 17, page of 9 handwritten notes, marked for 10 identification, as of this date.) 11 Q. When were these notes prepared? 12 A. These notes were prepared prior to 13 the submission of the October -- let's see which 14 exhibit. Exhibit 15. 15 Q. Are there any other notes which you 16 jotted down which you did not preserve from the date 17 the hard drive was furnished to you? 18 A. No. 19 Q. What are the letters at the top 20 right? 21 A. DHCP name server. 22 Q. What are the three IP addresses below 23 that? 24 MR. GABRIEL: Objection to form. 25 A. Those are the IP addresses of the 98 1 Jacobson 2 name server that were on her computer. 3 Q. What does that mean? 4 A. The name server, my best analogy is a 5 giant phone book that converts names and IP 6 addresses. So when you type in www.google.com, you 7 get the IP address of Google. 8 Q. What is the entry at the bottom, 9 "7704 repaired"? What is that a reference to? 10 A. In examining the hard drive, it 11 appeared that there was some type of repair of the 12 Windows operating system on that date. 13 MR. BECKERMAN: I would like to 14 mark as Exhibit 18 a single-page document 15 which says "wireless router" at the top. 16 (Defendant's Exhibit 18, single-page 17 document bearing "wireless router" at the 18 top, marked for identification, as of this 19 date.) 20 Q. When was this prepared? 21 A. 3/14. 22 Q. Now, You say "wireless router?" and 23 then say, "No." How did you know there was no 24 wireless router? 25 A. Again, by looking at the information 99 1 Jacobson 2 on Exhibit 6. 3 Q. How does that show you that there is 4 no wireless router? 5 A. Again, as I testified earlier, here 6 at the source address and that the KaZaA IP address 7 matched. 8 Q. And that tells you that there was no 9 wireless router? 10 A. Again, those are all public IP 11 addresses on both the computer and the device that 12 put the IP packet onto the internet, both at the 13 same IP address. 14 Q. And that's your sole basis for your 15 conclusion? 16 A. Yes. 17 MR. BECKERMAN: I would like to 18 mark as Exhibit 19 a two-page letter from 19 Verizon. 20 (Defendant's Exhibit 19, two-page 21 letter from Verizon, marked for 22 identification, as of this date.) 23 Q. Is that the source for your 24 information as to whose access account it was? 25 A. Yes. 100 1 Jacobson 2 MR. BECKERMAN: I would like to 3 mark as Exhibit 20 a resume, a one-page 4 resume, page number DJ0076. 5 (Defendant's Exhibit 20, one-page 6 resume, page number DJ0076, marked for 7 identification, as of this date.) 8 A. It is a printout of a file that I 9 found on the hard drive that I examined. It was 10 described in Exhibit 15. 11 Q. Did you know who prepared this? 12 A. I know it was on the hard drive and 13 it in the directory of user Kathleen on the system. 14 Q. Do you know who typed it? 15 A. No. 16 Q. Now, what does it say next to the 17 word "e-mail" in this resume? 18 A. J-C-Q-L-L-I-N-E. 19 Q. What tools did you use to determine 20 that the hard drive had not been used for a KaZaA 21 account? 22 A. I used EnCase to examine the captured 23 hard drive. 24 Q. When you used EnCase, did you know 25 that this matter was in litigation and that you were 101 1 Jacobson 2 an expert witness in this case? 3 A. Yes. 4 Q. Did you not have screens? When you 5 used EnCase, didn't you look at a computer screen? 6 A. Yes. 7 Q. Did you save what was on that screen? 8 A. No. 9 Q. Did you generate reports? 10 A. No. 11 Q. Now I'm not asking you if you printed 12 out reports or saved reports. I'm asking you if you 13 generated reports. 14 A. No. 15 Q. So you did not document your findings 16 in EnCase at all, did you? 17 A. No. 18 Q. Did Mr. Gabriel tell you to do that? 19 A. No. 20 Q. So did you feel that you could just 21 review it on EnCase and then come and testify from 22 memory at a trial? Is that what you intended to do? 23 A. I examined the hard drive, found no 24 evidence of file sharing software or audio files, 25 and so there was nothing to document. 102 1 Jacobson 2 Q. So you didn't feel was any need to 3 create documentation of what your study had shown? 4 A. There was no files to document. 5 Q. Is that because it did not 6 corroborate Plaintiff's case in any way? 7 MR. GABRIEL: Objection to form. 8 Argumentative. 9 A. The testimony says I found no KaZaA 10 or MP3 files and, therefore, there was nothing to -- 11 there were no screen shots to capture. 12 Q. Do you have any idea why the case 13 hasn't been dropped by now? 14 MR. GABRIEL: Objection to form. 15 Lack of foundation. 16 A. I don't get involved with -- so no. 17 MR. BECKERMAN: I would like to 18 mark as Exhibit 21 a one-page document 19 with a flowchart. 20 (Defendant's Exhibit 21, one-page 21 document with a flowchart, marked for 22 identification, as of this date.) 23 Q. Do you see item number 4? 24 A. You mean bullet number 4? 25 Q. Yes. 103 1 Jacobson 2 A. Yes. 3 Q. What does that say? 4 A. "Document findings." 5 Q. Did you know that you were going to 6 be giving sworn testimony in this case, including 7 your December declaration and possible deposition 8 and trial testimony? 9 A. Would you reread the question back. 10 (Record read.) 11 A. At the time I examined the hard drive 12 there were no scheduled depositions. 13 Q. So you thought it was okay not to 14 document your findings? 15 MR. GABRIEL: Objection to form. 16 A. I did document my findings, as shown 17 in Exhibit 17. 18 Q. When you say there were three user 19 names of interest, what did you mean by that? 20 A. In a Windows machine there are 21 default users that are created, like Administrator 22 and so on, that come with the installation of 23 Windows. So these were users that were added above 24 and beyond the default installation. 25 Q. So it doesn't actually tell you who 104 1 Jacobson 2 used the computer, does it? It just tells you the 3 user names? 4 A. Yes, these are user names for that 5 computer. 6 Q. And if someone was logged on under a 7 particular computer name and the computer was kept 8 on and another individual sat down and started using 9 the computer, you wouldn't know who that was, would 10 you, from the user name? 11 A. That's correct. 12 Q. Are you familiar with the declaration 13 that was given by the expert witnesses in the 14 Netherlands in the foundation case, the witness 15 statement of Henk Sips and Johan Pouwelse? 16 A. I would have to see the document. 17 MR. BECKERMAN: I would like to 18 mark this as Exhibit 22. It is a 19 three-page document entitled "Witness 20 statement of Henk Sips and Johan 21 Pouwelse." 22 (Defendant's Exhibit 22, three-page 23 document entitled "Witness Statement of Henk 24 Sips and Johan Pouwelse," marked for 25 identification, as of this date.) 105 1 Jacobson 2 MR. GABRIEL: I would like to 3 interpose a belated objection to the 4 characterization of the document as a 5 declaration. 6 MR. BECKERMAN: I agree. The 7 correct characterization should be as a 8 witness statement. So stipulated. 9 MR. GABRIEL: Thank you. 10 Q. Have you ever seen this document 11 before? 12 A. I've seen it. 13 Q. You have seen it? 14 A. I have seen it. 15 Q. In what context? 16 A. I believe my wife might have e-mailed 17 it and made a copy of it. 18 Q. Did anyone from the Plaintiff's law 19 firm send you a copy of it? 20 A. No. 21 Q. Did you ever access it yourself on 22 the internet? 23 A. Either she sent it to me directly or 24 a link to it, so I don't know if I got it as a 25 document or as a link to a document. 106 1 Jacobson 2 Q. Do you agree with the statement at 3 the bottom of Page 2 that detailed checks are, 4 therefore, required? 5 MR. GABRIEL: Objection to form. 6 Lack of foundation. 7 A. Would you read the question. 8 (Record read.) 9 A. I don't really know. They didn't 10 describe what they meant by detailed checks so I 11 can't -- I can't comment on that. 12 Q. We will turn to the next page. It 13 says, "We believe that the following procedure takes 14 the necessary precautions when trying to establish 15 if a user is making copyrighted works available for 16 download," and then they list certain procedures. 17 Do you agree that those procedures 18 take the necessary precautions? 19 MR. GABRIEL: Objection to form. 20 Lack of foundation. 21 A. The steps seem like reasonable 22 precautions. 23 Q. Going down a few paragraphs, there 24 are some terms. Do you agree that superpeer hopping 25 is a technical problem in trying to determine which 107 1 Jacobson 2 user might have violated copyright law? 3 MR. GABRIEL: Objection to form. 4 Lack of foundation. 5 A. They don't define what they mean by 6 superpeer hopping, so ... 7 Q. Don't you think they are referring to 8 the hopping from one supernode to another supernode, 9 shutting one down and starting another? 10 MR. GABRIEL: Objection to form. 11 Lack of foundation. Calls for 12 speculation. 13 Q. You are the expert. You have 14 indicated that you have studied KaZaA in depth. 15 Isn't it a fact that a single search on KaZaA can 16 hop from one supernode to another? 17 A. A search on KaZaA can prop you will 18 gate from one supernode to another. 19 Q. So don't you think that's what they 20 are referring to when they say superpeer hopping? 21 MR. GABRIEL: Objection to form. 22 Lack of foundation. Calls for 23 speculation. 24 A. I have not heard that term used, so I 25 don't know ... 108 1 Jacobson 2 Q. Would you agree that the fact that a 3 single search can switch from one supernode to 4 another to another to another would constitute a 5 technical problem in conducting such an 6 investigation? 7 MR. GABRIEL: Objection to form. 8 A. I would characterize it more as a 9 technical inconvenience than a problem. 10 Q. So you would agree that it is a 11 technical inconvenience that needs to be overcome? 12 A. I'm not saying that it hasn't been 13 overcome, if that's what your question is. 14 Q. My question is exactly what it said, 15 that it is a technical problem that needs to be 16 overcome.? 17 MR. GABRIEL: Technical 18 inconvenience. Let's be clear which 19 question you are asking, please. 20 Q. Is it a technical inconvenience that 21 needs to be overcome? 22 A. Yes. 23 Q. And you would agree that it requires 24 the taking of certain precautions? 25 MR. GABRIEL: Objection to form. 109 1 Jacobson 2 A. If by precautions you mean procedures 3 to understand that that can happen, yes. 4 Q. Would you agree that NAT translation 5 is a technical problem in conducting such an 6 investigation? 7 MR. GABRIEL: Objection to form. 8 Lack of foundation. 9 A. I would agree that that process -- 10 procedures and processes need to be put in place to 11 handle NAT translation. 12 Q. And you agree that firewall relaying 13 is a technical problem that needs to be considered 14 during the process and procedure? 15 MR. GABRIEL: Objection to form. 16 A. I would agree that firewall relaying 17 is something that needs to be considered during the 18 process and procedure. 19 Q. In the next paragraph they refer to 20 pollution. Would you agree that pollution is a 21 problem that needs to be taken into account in 22 conducting such an investigation? 23 MR. GABRIEL: Objection to form. 24 Lack of foundation. 25 A. I think processes and procedures need 110 1 Jacobson 2 to be put in place to deal with the issue of 3 pollution. 4 Q. Does KaZaA have limitations in file 5 searching? 6 A. If by limitations you mean is one 7 user limited to the scope of where they can search 8 across the entire KaZaA network, yes. 9 Q. What is meant by the term "computer 10 hygiene precautions"? 11 MR. GABRIEL: Objection to form. 12 Lack of foundation. 13 A. It is my opinion what they are 14 talking about is it's possible to get data from 15 multiple locations for one file and if you don't 16 take care watching where those -- where the data 17 comes from and how much data is produced, that you 18 could end up marking IP addresses that have 19 transferred no data. 20 Q. What is multi-peer downloading 21 contamination? 22 MR. GABRIEL: Objection to form. 23 Lack of foundation. 24 A. That goes to what I was saying, 25 multiple peer nodes contributing to a single file. 111 1 Jacobson 2 Q. Does the fact that MediaSentry 3 observed the computer solely through the internet 4 and did not have physical access to the computer 5 itself limit its observational power? 6 MR. GABRIEL: Objection to form. 7 A. Obviously weren't able to physically 8 view the individual typing on the keyboard. 9 Q. Is the internet secure and safe and 10 reliable? 11 MR. GABRIEL: Objection to form. 12 A. I guess it depends on how you define 13 those terms. Secure? No. The end nodes on the 14 internet often are not secure. Safe? I guess I'm 15 not sure what you are talking about as far as 16 safety. 17 Q. Can people hack into other people's 18 systems? 19 A. Yes. I would wrap that under the 20 security umbrella. 21 Q. Isn't it a fact that you teach a 22 course on how to do that? 23 A. Yes. 24 Q. Isn't it a fact that you teach 25 students how to crack passwords? 112 1 Jacobson 2 A. Yes. 3 Q. And you teach them about spoofing? 4 A. Yes. 5 Q. What is spoofing? 6 A. Spoofing is pretending to be somebody 7 else. 8 Q. What is redirection? 9 A. Depends on where we are talking about 10 it, but redirection is typically forcing the traffic 11 to go somewhere else or forcing the user to go 12 somewhere else. 13 Q. Does the existence of a firewall 14 guarantee security? 15 A. No. 16 Q. Isn't it a fact that when you teach a 17 course in information warfare, most of the people 18 will find some vulnerabilities in the network that 19 is being attacked? 20 MR. GABRIEL: Objection to form. 21 A. In the course I teach, I set up a 22 corporate environment that has vulnerabilities 23 associated with it as part of the exercise. 24 Q. And the vulnerabilities that you 25 build in are not unheard of in the real world; is 113 1 Jacobson 2 that correct? 3 A. That's correct. 4 Q. So an IP address can be spoofed, 5 right? 6 A. Yes. 7 Q. And a MAC address? 8 A. Yes. 9 Q. Did you ever recover the registry 10 entries from either of the two computers that you 11 have been testifying about? 12 A. I recovered the register entries from 13 the hard drive that I examined. 14 Q. Well, if you recovered them, where 15 are they? How come you never turned them over to 16 me? 17 A. In EnCase you open them up as a file 18 viewer and you can examine them by just looking at 19 them. 20 Q. So you viewed them but didn't 21 preserve a record of it? 22 A. The hard drive image is still in my 23 possession. 24 Q. But when you viewed it in EnCase, you 25 didn't make any documentation of what you saw in the 114 1 Jacobson 2 registry entries? 3 A. I was looking for evidence of the 4 KaZaA program and found none. 5 Q. But you actually had the register 6 entries in front of you on the screen and you didn't 7 make any record of that? 8 A. There wasn't anything to make a 9 record of. 10 Q. There were no register entries? 11 A. There were register entries, but none 12 associated with KaZaA. 13 Q. You were told by Mr. Gabriel just to 14 look for things that incriminated the defendant? 15 MR. GABRIEL: Objection to form. 16 Lack of foundation. Argumentative. 17 Q. Is that your testimony? Were you 18 directed only to find things that helped the 19 plaintiffs win their case? 20 MR. GABRIEL: Same objections. 21 A. I was told to examine the hard drive 22 for evidence of file-sharing software and evidence 23 of MP3. 24 Q. That's all you were told to examine 25 it for? So you weren't told to examine it for 115 1 Jacobson 2 evidence as to whether it had been -- the hard drive 3 had been changed or anything like that? 4 A. I wasn't directed to do anything more 5 than that, although as part of the examination I 6 did -- as noted in Exhibit 17, I noted, for example, 7 that the operating system was repaired on July 7th 8 of '04. 9 RQ MR. BECKERMAN: I call for the 10 production of those register entries. 11 MR. GABRIEL: They don't exist. 12 The witness doesn't have a duty to create 13 them and you have your image of his hard 14 drive. You can produce them yourself. 15 Q. So EnCase has no way of backtracking 16 your project? 17 A. The only record it keeps is when you 18 specifically write something to a report file; when 19 you see something, you explicitly say, "Put this in 20 a report." 21 Q. So you were just looking in the 22 registry for evidence of KaZaA? That's it? 23 A. I was looking for the IP address and 24 as shown in Exhibit 17, I was looking for evidence 25 of dates about the system, so the date the system 116 1 Jacobson 2 was repaired. 3 Q. Do some users of KaZaA fool people 4 with fake content? 5 MR. GABRIEL: Objection to form. 6 A. I don't have any firsthand experience 7 with that. 8 Q. What is a MAC address? 9 A. A MAC address is referred to as the 10 physical address, which is the address used to 11 transfer data packets across local area network. 12 Q. Does the cable modem have a MAC 13 address? 14 A. Yes. 15 Q. Does a wired router have a MAC 16 address? 17 A. Yes. 18 Q. Does a wireless router have a MAC 19 address? 20 A. Yes. 21 Q. Does an ethernet card have a MAC 22 address? 23 A. Yes. 24 Q. Is a network card a synonym for 25 ethernet card or is it something else? 117 1 Jacobson 2 A. An ethernet card would probably be 3 considered a subset of a network card. 4 Q. Do other network cards also have MAC 5 addresses? 6 A. There would be networks that do not 7 use the concept of a MAC address. 8 Q. Does a DSL modem have a MAC address? 9 A. It has it on its -- on the subscriber 10 side. 11 Q. Is there a limit to the number of 12 devices behind a single router? 13 A. Theoretical or practical? The answer 14 is "yes" to both, I guess. 15 Q. And what factors would limit it? 16 A. The IP address space would be one 17 limiting factor and then the performance would be 18 more of a practical limiting factor. 19 Q. Can you have a router behind another 20 router? 21 A. Yes. 22 Q. What is the MAC address of the 23 computer that was accessed by MediaSentry? 24 A. There is no documentation to indicate 25 what the MAC address of that computer was. 118 1 Jacobson 2 Q. What is the MAC address of the 3 computer whose hard drive you examined? 4 A. Since I did not have the ethernet 5 card, I don't know. 6 Q. What type of internet service was 7 used by the computer that MediaSentry was 8 interacting with? 9 A. There wasn't enough information from 10 Verizon to indicate whether it was a cable modem or 11 a DSL. 12 Q. So you don't know? 13 A. No. 14 Q. Did that connect to the internet 15 directly or through another device's MAC address? 16 A. Did what connect? 17 Q. When that computer was on line with 18 or supposedly on line with MediaSentry, was it 19 directly or was it through another device's MAC 20 address? 21 MR. GABRIEL: Objection to form. 22 A. Every time a packet goes through a 23 cable modem, a router, a NAT, the MAC address is not 24 preserved; it is destroyed and recreated on the 25 other side. 119 1 Jacobson 2 Q. So the answer is? 3 A. Could you reread the original 4 question. 5 (Record read.) 6 A. Are you talking about which address 7 it presented to the ISP? 8 Q. You can't answer the question the way 9 it's asked? 10 A. I don't know where -- 11 Again, as the packet moves through 12 the internet, every device that picks up the packet, 13 it retransmits and creates a new MAC address. 14 Q. Do you know whether it connected to 15 the internet directly or through another device's 16 MAC address? If you don't know you can say you 17 don't know. 18 MR. GABRIEL: Objection to form. 19 You can answer the question. 20 A. Stated the way it's stated, no, I 21 don't know. 22 Q. How many devices accessed the 23 internet through Marie Lindor's internet access 24 account? 25 A. I have evidence of one device with 120 1 Jacobson 2 the IP address that we have talked about in 3 Exhibit 6, that one device being connected to the 4 internet during the times as described in 5 Exhibit 16. 6 Q. How many MAC addresses have accessed 7 the internet through Marie Lindor's account? 8 A. I have no way of knowing. 9 Q. When is a MAC address assigned to a 10 computer? 11 A. MAC addresses are actually assigned 12 to the network cards by the network card vendor. 13 Q. And is that also true for any other 14 network device? 15 A. In the ethernet world, yes. MAC 16 addresses are assigned. Blocks are assigned to the 17 vendors and the vendors allocate individual 18 addresses. 19 Q. Did the computer which you examined 20 have a wireless card? The computer whose hard drive 21 you examined, did that have a wireless card? 22 A. All I received was the hard drive. I 23 did not receive the -- 24 Q. So you don't know? 25 A. Correct. 121 1 Jacobson 2 Q. Can an ethernet card be removed from 3 one PC and put into another? 4 A. If it is an actual card as opposed 5 to -- connected to -- actually on the motherboard. 6 Q. If you were an internet pirate or 7 cracker who wanted to spoof a MAC address, could you 8 easily find the MAC address by, let's say, finding a 9 box that a cable modem had come in and just writing 10 down the MAC address from that? 11 MR. GABRIEL: Objection to form. 12 Lack of foundation. 13 A. I don't know if they write the MAC 14 addresses on the outside of cable modem shipping 15 boxes. 16 Q. You can manually reassign a new MAC 17 address, can you not? 18 A. In a lot of systems, yes. 19 Q. What is reprogramming a MAC address? 20 MR. GABRIEL: Objection to form. 21 A. I've never heard it quite put that 22 way, but my understanding would be that that would 23 be changing the MAC address of the device. 24 Q. Did you or MediaSentry ever actually 25 know the MAC address of either of the computers? 122 1 Jacobson 2 MR. GABRIEL: Objection to form. 3 Lack of foundation as to MediaSentry. 4 A. I did not know the MAC address. I 5 cannot testify to what MediaSentry knew in that 6 case. 7 Q. How would one spoof an IP address? 8 A. Can we go off the record for a 9 second? Am I allowed to say that? 10 MR. GABRIEL: You need to answer 11 his question first. If there is an issue 12 with the question, you can tell him. 13 A. Long version or short version? 14 Q. Short version. 15 A. Okay. Boy, there is no short 16 version. 17 Q. There are many ways to do it, is that 18 not correct? 19 A. Well, there is many ways and it 20 depends for what purpose as to whether those ways 21 would work. 22 Q. Okay. It's not necessary to really 23 go into detail. 24 A. Okay. 25 Q. There are many ways to spoof an IP 123 1 Jacobson 2 address? 3 A. Not all of which work. Correct. 4 Q. Did you personally verify the IP 5 number? 6 A. The IP address on the hard drive, 7 since it's DHCP, the IP address is not committed to 8 the hard drive. 9 Q. So the answer is no, you did not 10 verify the IP address? 11 A. Not on the hard drive. 12 Q. And how did MediaSentry get the IP 13 address? 14 MR. GABRIEL: Objection to the 15 extent it was asked and answered. 16 Go ahead. 17 A. I don't know the exact process and 18 procedures that MediaSentry used. 19 Q. So you couldn't test or verify the 20 procedures? You didn't know what they were? 21 A. Given the procedures, I could test 22 them. The method that I would use is, again, since 23 every packet -- 24 Q. No. The question was -- I was asking 25 whether you verified the way that -- the method that 124 1 Jacobson 2 MediaSentry used. 3 A. No. 4 Q. Do you know what the IP address was 5 of the screen shot? 6 MR. GABRIEL: Objection to form. 7 A. The screen shot was a screen shot of 8 the files associated with the user. 9 Q. Well, they would have had to have 10 been a dynamic IP address assigned it that, would it 11 not have, to that connection? 12 MR. GABRIEL: Objection to form. 13 A. You have an IP -- you have an IP 14 connection to the supernode and then to transfer the 15 files, you make an IP connection to the machine that 16 has the -- that has the files. 17 Q. When you did the forensic examination 18 of the hard drive, other than telling you that they 19 wanted you to look for evidence of KaZaA, were there 20 any other instructions given to you? 21 A. Look for the -- any MP3 files and 22 then just a general look for anything that may be 23 associated with -- you know, with MediaSentry and my 24 testimony or my expert report. So things like IP 25 addresses, et cetera. 125 1 Jacobson 2 Q. You say it's not difficult to 3 determine whether a computer was connected with a 4 wireless router based on how IP's are assigned? How 5 could you possibly tell from the way IP's are 6 assigned whether or not it was connected to a 7 wireless router? 8 A. Again, back to Exhibit 6 where the 9 machine itself reports its IP address and so does 10 the device with the global internet address. A 11 wireless router is going to have an internal address 12 and then a public address, and so you will see a 13 discrepancy in those two IP addresses. 14 Q. How did you make that determination 15 in this case? I'm not sure I follow that. 16 You put in your declaration on 17 December 19th "Based on how IP's are assigned, it is 18 not difficult to determine whether a computer was 19 connected to the internet via a wireless router. 20 This computer was not." How did you determine that 21 that computer was not connected to the internet via 22 a wireless router? 23 MR. GABRIEL: Objection. Asked and 24 answered. 25 A. This computer had a public IP address 126 1 Jacobson 2 that matched the IP address that was in the packet 3 that was transmitted onto the internet from an entry 4 point into the internet. And so, therefore, since 5 the computer said it had the same address as the 6 packet ... 7 Q. I don't understand your testimony. 8 What do you mean by a public IP address? 9 A. The public IP space is divided into 10 address ranges. A majority of the addresses are to 11 be handed out for devices that are directly 12 connected to the public -- to the internet. Some of 13 the addresses have been reserved for private 14 addresses, addresses that cannot show up on the 15 internet. They will not be routed across the 16 internet. These are the addresses used by NATs and 17 wireless routers and so on as you have shown in 18 your -- 19 Q. Don't look for the documents. 20 A. The image with the picture where you 21 had the 192168 addresses. Those, for example, are 22 private IP address space. 23 Q. So you are going to rely on what you 24 just said. That's the way you know it wasn't a 25 wireless router. Everything you have just said now 127 1 Jacobson 2 establishes that it was not a wireless router? 3 A. In my opinion, yes. 4 Q. Was KaZaA fully installed on the 5 first computer? 6 MR. GABRIEL: Objection to form. 7 A. If by the first computer you mean the 8 computer that MediaSentry reported on, that was 9 running a KaZaA client. 10 MR. BECKERMAN: Read back that 11 answer. 12 (Record read.) 13 Q. I asked you if it was fully installed 14 on the computer. 15 MR. GABRIEL: If that's a question, 16 I object. 17 A. The KaZaA application was installed 18 and running on that computer. 19 MR. GABRIEL: The record should 20 reflect that the document Dr. Jacobson was 21 looking for was Exhibit 8 with the 192IP 22 address. That's what he said, just for 23 clarity. 24 Q. Other than this two-page document 25 from Verizon which was sent to Jenner & Block law 128 1 Jacobson 2 firm, did you see anything else from Verizon? 3 A. No. 4 Q. Do you know what procedures Verizon 5 employed to link Ms. Lindor's name and address to 6 the alleged IP address? 7 A. No. 8 Q. Do you know who conducted the 9 research? 10 A. No. 11 Q. Do you know if the procedures were 12 accurately and competently followed? 13 A. I have no way of knowing that. 14 Q. Do you know if the search was free 15 from human and mechanical error? 16 A. I have no way of knowing. 17 Q. Have the ISP's ever misidentified a 18 subscriber? 19 MR. GABRIEL: Objection to form. 20 Lack of foundation. 21 A. I have no way of knowing. 22 Q. Have the ISP's ever identified a 23 customer who is not even a subscriber at the time of 24 the infringement? 25 MR. GABRIEL: Objection to form. 129 1 Jacobson 2 Lack of foundation. 3 A. I have no way of knowing. 4 Q. Did you see their logs? 5 A. All I saw from Verizon is what is 6 shown in Exhibit 19. 7 Q. Were MediaSentry's clocks 8 synchronized with Verizon's? 9 MR. GABRIEL: Objection to form. 10 Lack of foundation. 11 A. I have no way of knowing. 12 Q. How many people were assigned this IP 13 address during the 24 hours of August 7, 2004, 14 141.155.57.198? 15 A. The date you said was August 7th? 16 Q. August 7, 2004. 17 A. I have no way of knowing that. 18 Q. Is it true that the ISP keeps a log 19 of all IP address assignments? 20 MR. GABRIEL: Objection. Lack of 21 foundation. 22 A. I don't know how Verizon operates 23 internally. 24 Q. Does the log contain the name and 25 address of a subscriber or does it contain a MAC 130 1 Jacobson 2 address? 3 MR. GABRIEL: Same objection. 4 A. I have no idea what is in their 5 internal logs. 6 Q. How did Verizon link Ms. Lindor's 7 name to that IP address? 8 MR. GABRIEL: Same objection. 9 A. I have no knowledge about Verizon. 10 Q. So is it fair to say that all of your 11 reports are based on the assumption that the 12 information which you obtained from Verizon was 13 accurate? 14 A. Yes. 15 Q. And you have no idea how they 16 obtained that information; is that correct? 17 A. I have no firsthand knowledge of how 18 they obtained that information. 19 Q. Do you have some secondhand knowledge 20 of how they operated? 21 A. I could speculate as to how they 22 might do it. 23 Q. But you don't know? You just would 24 be speculating? 25 A. Yes. 131 1 Jacobson 2 Q. I am sure Mr. Gabriel wouldn't want 3 you to speculate. Did you make any attempt to 4 verify the information? 5 A. The Verizon information? 6 Q. Yes. 7 A. The only verification that I do is I 8 compare the Verizon subpoena response date, time, IP 9 to the subpoena itself to verify that they -- that 10 Verizon is reporting back on the same data that was 11 requested. 12 Q. Do you know if Ms. Lindor's apartment 13 has a wired router? 14 A. I don't know anything about 15 Ms. Lindor's apartment. 16 Q. So would you know if her apartment 17 had a wireless router? 18 A. Again, I don't know anything about 19 Ms. Lindor's residence. 20 Q. Would it have been possible to have 21 more than one router? 22 MR. GABRIEL: Objection to form. 23 A. It's possible to have any number of 24 routers. But given the IP address correlation, 25 given the IP address in the packet in the computer 132 1 Jacobson 2 are both republic. 3 Q. What is a wireless access point? 4 A. A wireless access point is the 5 wireless device that actually -- it is a device that 6 actually interfaces with the wireless devices, the 7 machines with wireless cards, so that actually is 8 the base station transmitter. 9 Q. How does that relate to a wireless 10 router? 11 A. That's part of a -- that's part of 12 the router. The access point we typically talk is 13 the wireless side. 14 Q. Didn't you say in your declaration 15 under penalty of perjury that your conclusion that 16 it was not connected to the internet via a wireless 17 router was based in part on the registry entries 18 recovered from the computer? 19 A. Yes. 20 Q. And you didn't feel it was important 21 to identify those registry entries? 22 A. Again, since I didn't find anything 23 there was nothing to document and since I can -- 24 The hard drive is still in my 25 possession. 133 1 Jacobson 2 Q. Well, do you think you can now go 3 generate more reports after having gone through this 4 deposition and then come up with them at the trial 5 and surprise me with them? 6 MR. GABRIEL: Objection. 7 Argumentative. We are aware of what our 8 obligations are. 9 Q. You said in your declaration that 10 there was no internal IP address here. What did you 11 mean by that? 12 A. Which declaration are you reading? 13 Q. Your December 19th declaration. You 14 said there was no internal IP address here. 15 MR. GABRIEL: I don't believe you 16 marked it as an exhibit. 17 Q. Do you doubt that you put that in 18 your declaration? 19 MR. GABRIEL: Wait. He is talking 20 about your December declaration. He has 21 not marked it as an exhibit, if that is 22 what you are looking for. 23 Q. Well, do you doubt that that's what 24 you said? Let me quote. 25 "I base this on the data mentioned 134 1 Jacobson 2 above as well as on the registry entries recovered 3 from the computer and the fact that there was no 4 internal IP address here." Do you not know what 5 that statement means? 6 A. I know what that statement means. I 7 assume if you are reading it, it is indeed what I -- 8 I don't remember verbatim what I said 9 without seeing the report. 10 MR. BECKERMAN: Please mark this as 11 Exhibit 23. It is a declaration dated 12 December 19, 2006. 13 (Defendant's Exhibit 23, declaration 14 dated December 19, 2006, marked for 15 identification, as of this date.) 16 Q. I refer you to Page 4, Paragraph 5, 17 second sentence, and ask you what you were talking 18 about. 19 Actually, let me go to this first. 20 When you say the registry entries were recovered, 21 they weren't recovered; you are just saying you saw 22 them and then kept them to yourself. Is that 23 correct? You didn't recover them? 24 MR. GABRIEL: Objection to form. 25 Argumentative. 135 1 Jacobson 2 Q. You read them and made no notation or 3 record or report of them; is that correct? So when 4 you say recovered -- 5 A. In a Windows PC the registries 6 actually exist in several places and so to get a 7 view of all of them, you end up through EnCase 8 running their internal program which puts the 9 registries in a human, readable format. So that's 10 what I meant by the word "recovered." 11 Q. What did you mean when you said there 12 was no internal IP address here? 13 A. There was no evidence of an 14 internal -- of the internal addresses like the 15 192.168 addresses that you find when you have a 16 wireless router. 17 Q. So in preparing your analysis, you go 18 directly from the MediaSentry documents to the 19 report that you write for the RIAA lawyers and there 20 is no intermediate work papers or analysis sheets? 21 A. Yes. That's Exhibit 18. 22 Q. That's it? That's the only thing 23 that you prepare before preparing your report? 24 A. Yes. 25 (Recess taken.) 136 1 Jacobson 2 Q. If I was on the internet right now 3 and my IP address was 195.175.1.2, how would you 4 determine whether I was connected through a wireless 5 router or not? 6 A. We look at the -- if all I saw was a 7 single packet from you with no other data, I 8 couldn't make that determination. But if I saw a 9 payload that also reported your IP address, then I 10 could make that determination. 11 Q. So let's say I sent you an e-mail. 12 Would you be able to tell? 13 A. Not with every e-mail. There may be 14 configurations in which an e-mail would disclose 15 that information. 16 Q. Now, going back to what you said 17 about the packet, would you see the private IP? 18 A. If the application reported the 19 private IP as part of the payload, but not as part 20 of the IPV4 header. 21 Q. And how does it distinguish between 22 wireless and not wireless? 23 MR. GABRIEL: Objection to form. 24 A. You wouldn't be able to tell the 25 difference between a router with private addresses, 137 1 Jacobson 2 whether it was wireless or not wireless. 3 Q. Does the packet identify whether the 4 user is wireless or not? 5 A. It depends on which packet you see? 6 Q. How would a packet tell you that it's 7 wireless? 8 A. If I actually captured the wireless 9 packet, its MAC address is larger than the MAC 10 address of a -- on the wired side, along with the 11 frame format is different. 12 Q. The MAC address of a wireless is a 13 different type of MAC address? 14 A. Its layout is different. 15 Q. Is a MAC address visible outside of 16 the local network? 17 A. Not of the internal machines. 18 Q. So how would a packet on the public 19 internet have a MAC address header? 20 A. Every packet has some type of MAC 21 address header. 22 Q. Does NAT hide the private IP? 23 A. If by "hide" you mean that the 24 private IP does not show up in the IPV6 header, that 25 is correct. 138 1 Jacobson 2 Q. What is the name and model of the PC 3 whose hard drive image you examined? 4 A. I don't know. 5 Q. What is the MD5 hash of the hard 6 drive you examined? 7 A. I don't recall what that is. 8 Q. What is the SHA1 hash of the hard 9 drive image you examined? 10 A. I don't even recall looking at that. 11 Q. What kind of hashing does KaZaA use? 12 A. I don't remember the exact algorithm 13 that it uses. 14 Q. Would it refresh your recollection 15 for me to tell you that it uses UU Hash? 16 A. I have no reason to doubt that. 17 Q. Do you know why MediaSentry compiled 18 the list with the SH1 values instead of the UU Hash 19 values? 20 A. Which list? 21 Q. You are the person who is testifying 22 about the MediaSentry printouts. 23 MR. GABRIEL: I will object. He 24 didn't testify about hash values at all. 25 Q. Isn't it a fact that they have a list 139 1 Jacobson 2 of SHA1 hash values? 3 MR. BECKERMAN: Withdrawn. I 4 withdraw the question. 5 Q. Can multiple users of KaZaA have the 6 same user name? 7 A. Yes. 8 Q. Can users change their nickname in 9 KaZaA? 10 A. Yes. 11 Q. Do KaZaA nicknames uniquely identify 12 a person? 13 A. No. 14 Q. Could I create a user name 15 "Dr. Jacobson" at KaZaA? 16 A. Yes. 17 Q. Does KaZaA operate as a background 18 service? 19 MR. GABRIEL: Objection to form. 20 A. You can minimize KaZaA and have it 21 run out of the system tray. 22 Q. Is it possible that someone who has 23 the computer on and has KaZaA running might not even 24 know it's running? 25 A. It's possible. 140 1 Jacobson 2 Q. Is there a way through the internet 3 to remotely control someone else's computer? 4 MR. GABRIEL: Objection to form. 5 Lack of foundation. 6 A. It's possible. 7 Q. What is a zombie? 8 A. In reference to computer security, a 9 zombie is a program that is under control of some 10 other master program which is under control of some 11 individual. 12 Q. What is a cracker? 13 A. When I use the term, it is in 14 reference to either a person or process to break 15 passwords. 16 Q. What is a drone? 17 A. Again, in computer security 18 terminology that, again, would be a piece of 19 software that's under control by another individual. 20 Q. When you provide your investigations, 21 do you do anything to verify or to determine whether 22 or not the computer in question was under control by 23 an outside remote user? 24 A. No. 25 Q. Do you know who conducted the 141 1 Jacobson 2 MediaSentry investigation? 3 A. No. 4 Q. Do you know the qualifications and 5 training of anyone who conducted the investigation? 6 A. No. 7 Q. Are screen shots reliable evidence, 8 in your opinion? 9 MR. GABRIEL: Objection to form. 10 Lack of foundation. Calls for a legal 11 conclusion on its face. 12 A. I don't know what represents legal 13 evidence in a court of law. 14 Q. Do you consider screen shots 15 reliable? 16 MR. GABRIEL: Objection. 17 A. A screen shot is an image of the 18 application and the application data that is shown 19 on the screen at that time. 20 Q. Can it be subject to manipulation or 21 forgery? 22 MR. GABRIEL: Objection to form. 23 Calls for speculation. 24 A. Any image can be subject to 25 manipulation. 142 1 Jacobson 2 Q. Could it be altered in the graphics 3 editing program? 4 MR. GABRIEL: Same objections. 5 A. Any image can be altered in the 6 graphics editing program. 7 Q. Did you take any steps to verify the 8 authenticity of the screen shot? 9 A. No. 10 Q. Did you take any steps to verify that 11 the song files were genuine? 12 A. Other than what was reported through 13 MediaSentry and through the certificates of -- I 14 can't recall what they are called exactly, but 15 through the documents provided by the recording 16 industry. 17 Q. You yourself did nothing to verify 18 that they were genuine? 19 A. Other than through the documentation 20 I was provided. 21 Q. What did MediaSentry do to verify 22 that they were genuine? 23 MR. GABRIEL: Objection to form. 24 Lack of foundation. 25 A. I don't know what MediaSentry did. 143 1 Jacobson 2 Q. Did you verify that the IP address 3 had not been highjacked? 4 MR. GABRIEL: Objection to form. 5 A. I relied on the Verizon documentation 6 and so, no, I did not. 7 Q. Did you verify that the IP address 8 had not been faked? 9 MR. GABRIEL: Same objection. 10 A. I relied on the Verizon 11 documentation. 12 Q. Did you verify that the IP address 13 had not been spoofed? 14 MR. GABRIEL: I will object to the 15 form. Lack of foundation. 16 You can answer. 17 A. Only that I can say that it was an IP 18 address that was within Verizon's domain. 19 Q. Is a log file a text file? 20 A. It can be. 21 Q. Were these log files text files? 22 A. The originals I believe came that 23 way. When I receive them, they are .PDF documents. 24 Q. Can text files be easily altered? 25 MR. GABRIEL: Objection to form. 144 1 Jacobson 2 A. Yes. 3 Q. In your report you said the lack of 4 user-created files and e-mail leads you to believe 5 that this computer wasn't used very much. What did 6 you mean by user-created files? 7 A. When I looked through the hard drive 8 there were very few files that were created by 9 user-run applications, like documents. 10 Q. Is it possible to use a computer for 11 extended periods without creating any user files? 12 MR. GABRIEL: Objection to form. 13 A. It's possible. 14 Q. If you were, let's say, surfing the 15 internet and clearing the cache, would there be any 16 user-created files from that? 17 A. As long as you didn't download 18 anything. 19 Q. If you were listening to any CD's, 20 would there be any user-created files? 21 A. No. 22 Q. If you were playing Minesweeper or 23 Solitaire, would there be any user-created files? 24 A. I believe Solitaire you can save a 25 game. 145 1 Jacobson 2 Q. If you were just playing Minesweeper 3 or Solitaire, would there be any user-generated 4 files? 5 A. No. 6 Q. If a user used web-based e-mail such 7 as Hotmail, Yahoo or Gmail, would any of those 8 e-mails be stored on the hard drive? 9 A. They don't have to be. 10 Q. Can you tell how many people used the 11 computer from which the hard drive came that you 12 examined? 13 A. I can tell how many accounts were on 14 the hard drive, how many user accounts. 15 Q. But you can't say how many people 16 used it? 17 A. Living, breathing people? No. 18 Q. During your hard drive inspection, 19 what files did you find in the deleted sectors of 20 the disk? 21 A. Very few, and none that matched the 22 profile of KaZaA or MP3 files. 23 MR. BECKERMAN: Let's take a short 24 break. 25 (Recess taken.) 146 1 Jacobson 2 Q. Did you examine the system registry 3 for the computer that had the hard drive? 4 A. I examined the registry from the hard 5 drive. 6 Q. Did it show that any other hard drive 7 had ever existed in that computer? 8 A. I didn't specifically look for that. 9 I don't recall that there was an indication of that. 10 Q. So you have no reason to think that 11 the hard drive was replaced? 12 A. Not -- no. 13 Q. And it is a fact, is it not, that the 14 system registry would have disclosed that if it had 15 taken place? 16 A. If you would have rebuilt the system 17 from scratch and copied the data files over to new 18 hard drive, the system registry would have only 19 shown the creation date or installation date of the 20 operating system. 21 Q. Isn't it a fact that the system 22 registry contains information about each hard drive 23 that's ever been connected to the computer, 24 including the manufacturer, the size of the hard 25 drive and in some instances the serial number? 147 1 Jacobson 2 A. Of all hard drives connected while 3 that system registry was on that hard drive, if you 4 pull out the hard drive that had that system 5 registry and plugged a brand new one into the 6 machine and rebuilt the operating system, there 7 would be no evidence of that original hard drive you 8 pulled out. 9 Q. Was there any evidence that that had 10 taken place here on or after August 7, 2004? 11 A. No. 12 Q. Does every internet packet contain a 13 MAC address? 14 A. No. 15 Q. Does a MAC address tell you if a 16 device is wired or wireless? 17 A. If you can see the MAC address of the 18 transmitting device you could see whether that 19 device was wired or wireless. 20 Q. Now, if it was a computer going 21 through a wireless router, would you see the MAC 22 address of the computer? 23 A. Where am I looking for the MAC 24 address? 25 Q. Where you say it exists. 148 1 Jacobson 2 A. MAC address exists between any two 3 nodes -- some type of physical address exists 4 between every pair of communicating nodes on the 5 internet. 6 Q. How would you see the MAC address of 7 a transmitting device? 8 A. I'd have to have a monitoring device 9 on the media -- median that the transmitting device 10 was using. 11 Q. And did you have such a monitoring 12 device? 13 A. No. 14 Q. Does an IP address tell you if the 15 device is wired or wireless? 16 A. No. 17 MR. BECKERMAN: I have no further 18 questions. 19 MR. GABRIEL: I think I just have 20 three clarification questions. 21 MR. BECKERMAN: Then I might have 22 some clarifying questions of my own then. 23 MR. GABRIEL: I understand. 24 EXAMINATION BY 25 MR. GABRIEL: 149 1 Jacobson 2 Q. Dr. Jacobson, Mr. Beckerman asked you 3 some questions about the processes that you used 4 both when you did your first report and also when 5 you reviewed the hard drive, and you gave testimony 6 about that. Do you recall? 7 A. Yes. 8 Q. With respect to the processes that 9 you used, is it your view that reasonable experts in 10 your fields use the same processes? 11 A. Yes. 12 Q. Is there any other way to do what you 13 did, to your knowledge? 14 A. The hard drive examination could have 15 been done with any one of a number of tools, but all 16 of those tools behave in roughly the same way. 17 Q. Mr. Jacobson, with respect to the 18 reports in the declaration that you did and 19 Mr. Beckerman asked you about, he asked you whether 20 you had discussed any alternative explanations for 21 the conclusions you reached. Do you recall him 22 asking you that? 23 A. Yes. 24 Q. You did talk about the absence of a 25 router. 150 1 Jacobson 2 MR. BECKERMAN: Objection. 3 Leading. 4 Q. Yes? 5 A. Yes. 6 Q. Mr. Beckerman had asked you questions 7 about the instructions that I or my firm gave you in 8 terms of what you were supposed to look for on the 9 hard drive, correct? 10 A. Yes. 11 Q. And your testimony will speak for 12 itself. I think you said look for KaZaA, look for 13 MP3 files, anything associated with your expert 14 report. Do you recall giving that general 15 testimony? 16 A. Yes. 17 Q. Did we also ask you to look if 18 anything was deleted? 19 A. I believe you did. 20 Q. And did you do that? 21 A. Yes. 22 Q. Mr. Beckerman asked you a lot of 23 questions today about what you relied on and he 24 asked you whether you had verified different things. 25 For example, the Verizon information was one of the 151 1 Jacobson 2 things he asked you if you verified. Do you 3 remember just being asked those questions? 4 A. Yes. 5 Q. With respect to the various data you 6 relied on from MediaSentry or Verizon, do you have 7 any information sitting here today, Dr. Jacobson, to 8 suggest that any of that is not correct? 9 A. No. 10 Q. Do you have an opinion as to whether 11 a reasonable expert in your field would rely on 12 information like that? 13 MR. BECKERMAN: Objection. He 14 hasn't shown himself qualified to give an 15 opinion on something like that. 16 Q. You can answer. 17 A. I believe that a person in my field 18 would use the same information. 19 Q. Last question. Would you look at 20 Exhibit 8, please. 21 A. Yes. I found it. 22 Q. A couple of times today you alluded 23 to this exhibit and referred to it or you talked 24 about -- and the record speaks for itself, I'm just 25 trying to get us in the same place -- an internal IP 152 1 Jacobson 2 address and 192. Does the number 192 here somehow 3 correlate with an internal IP address? 4 A. Yes. The internet registration 5 authority, which is basically the governing body of 6 IP addresses, has allocated three address ranges 7 that are to be used internally only, they are not to 8 show up on the internet, and the 192.168 is one of 9 those blocks of addresses. 10 Q. And with respect to the IP -- the 11 public IP address that you talked about a lot today 12 relating to this case, was that within one of the 13 ranges for internal addresses? 14 A. No. 15 MR. GABRIEL: That's all I have. 16 MR. BECKERMAN: I have no further 17 questions. 18 MR. GABRIEL: Thank you for your 19 courtesy. We are going to run out and 20 make a plane. 21 --o0o-- 22 (Time noted: 2:28 p.m.) 23 24 25 153 1 2 C A P T I O N 3 4 The Deposition of DR. DOUGLAS W.
