RIAA Security Expert's Quest For Reliability

NewYorkCountryLawyer writes "In the ongoing case of UMG v. Lindor, Ms. Lindor has now moved to exclude the trial testimony of the RIAA's 'expert' witness, Dr. Doug Jacobson. Jacobson is the CTO and co-founder of Palisade Systems, Inc, and a teacher of internet security at Iowa State, but in his February 23rd deposition testimony she argues he failed to meet the reliability standards prescribed by Daubert v. Merrell Dow Pharmaceuticals, Inc. and Federal Rule of Evidence 702. The Groklaw and Slashdot communities participated in both the preparation of the deposition questions, and the vetting of the witness's responses."

    What's so difficult to read? Different colors? Anyways, it basically says that some lawyers in new York are in an ongoing battle with the RIAA (via UMG) and a recent "expert" is being questioned on the grounds that they did not meet a certain standard to an expert witnesses, set forth by case precidence. It also states that Slashdot and Groklaw participated in formulating questions asked of the 'expert' as well as analysis of it's response.

    Am I the only one who does NOT despise Jacobson? I thought he held up fairly well in that deposition under the pressure of some of Mr. Beckerman's more irrelevant questions - for example, the ones targetting his vocabulary, or the ones about why he didn't produce imaginary documentation detailing an absense of evidence.

    There are plenty of weak points in the RIAA's case as a whole. One could attack the chain of identity leading to the defendent - is the infringing activity traced to the correct IP, and is the IP at that time actually the one that belonged to Ms. Lindor, and can we be reasonably sure the activity took place on her computer, and we don't even know that she was the one at the computer so would she even be liable... The chain of identity is probably the best weak point in their case, but you could also argue that the damages are negligable and fight the absurd statutory fee, or that perhaps no uploading took place and the torrent was all seeded one way.

    There are a number of legitimate arguments to be made, but the point I'm getting at is I don't see how the deposition of Jacobson attacked any of them sufficiently to prove or disprove his competence as an expert witness. Slashdot was quick to point out the minor screw-ups in his testimony, but many of those statements were perfectly fine in the context of explaining the technology to a layperson. Some of the "holes" in his argument were so unlikely that I would not even consider them reasonable doubt in a criminal case. Do you really think someone actually decided to frame the woman by filesharing wirelessly and changing her MAC address and internal NAT mappings to mask the presence of a wireless router? I don't.

      RTFA and follow the links.

      The main argument is that all of his testimony is based on assuming the ISP and MediaSentry provided accurate information. MediaSentry and the ISP are not going to testify. In his deposition, the RIAA "expoert" stated he has no idea how MediaSentry or the ISP came to their conclusions. The cases sited require that the expert testimony start with verifiable facts, not with unverifiable information provided by third parties that will not even be in court.

      Furthermore, the sited case law requires that the expert use peer reviewable methods. The RIAA's "expert" made up his own methods that have never been published or reviewed. So he can't be considered an expert by the court.

      I kind of hope the judge refuses this motion. The RIAA's "expert" made enough errors in his deposition that he will be made a laughing stock on the stand.

      I don't remember him specifically saying that a network card does not have an IP address, but I think I do remember him attributing IPs to computers. I do not consider this to be a mistake because there's no reason why we can't consider a single NIC to be part of a personal computer. Really, why make a distinction between the two unless there's more than one NIC on a single host? It does not affect the equation as far as NAT and other relevant aspects.
      (note: I read the whole transcript)

      You missed the part(s) where he continued to state that the public IP address identifies one, and only one, computer. Even after admitting the existence of NAT, he kept returning to this assumption.

    It may have taken some effort, but the testimony reads like a playbook for anyone who needs to pick apart any RIAA expert.

    It's still very much news for nerds, stuff the matters. The the RIAA cases deal with an activity that many of us have participated in the past, present or future, and regardless of your opinion of the state of copyright law. It's important to know how one might respond if served.

    More importantly though, these cases indirectly impact many other activities, many of which I think the great majority of the community feels are not unethical, which involve limits of copyrights, security, DRM, etc.

    And speaking as somebody who's a US citizen who knows a fair amount as an amateur about the law and constitution as written documents, these cases, as well as the SCO entries, are certainly educating me greatly about how the law is actually practiced outside of my personal reading of it. Routine trial motions are relevant when they deal with something that is important to track, especially when most of the community doesn't know what's a routine motion and what isn't. I personally hope that at the very least everybody from the US learns from these, since being able to describe with accuracy and detail the problems we have with the current state of the laws is the only way that all the letters, e-mails etc to legislators are going to have any measurable impact.

  10. Dr. Jacobson is alright. Just not as a witness. by Anonymous Coward · · Score: 3, Interesting
    I don't doubt that Dr. Jacobson knows what he is talking about. However, he doesn't come anywhere close to meeting the requirements for testifying in court. Check out the second link which ultimately goes to the motion to exclude his testimony. The court needs to look at four criteria to determine if the expert's testimony is allowable as evidence:

    1. whether the expert's conclusions have been tested or are testable
    2. whether the expert's conclusions have been published and subjected to peer review
    3. the potential or known error rate
    4. whether the expert's conclusions have gained general acceptance in the relevant scientific community.

    By his own admission Dr. Jacobson fails on every count.

    We all know there are huge holes in analyzing the evidence. Ms. Lindor can not call an expert to dispute Dr. Jacobson's testimony because his methodology has not been published. it has not been subject to peer review. There has been no formal analysis of the reliability. And his methods have not gained enough acceptance for anyone else to be familiar with them. If Ms. Lindor can not call her own witness she is denied due process. The RIAA may as well just use voodoo science.

    If Dr. Jacobson's methodology had been subject to peer review, there would be peer-reviewed articles analyzing the details brought up in the deposition such as IP spoofing, malware, the Kazaa protocol, and MediaSentry.

    The motion to exclude brings up a couple other huge problems with Dr. Jacobson's testimony. It's not that Dr. Jacobson is a bad guy or that he is somehow incompetent. The problem is that Dr. Jacobson can not draw any 'expert' conclusions in the legal sense. NewYorkCountryLawyer always puts the word 'expert' in quotes when he mentions Dr. Jacobson. I think that's because Dr. Jacobson is not legally an expert.

  11. Re:Why exclude? No real problem with his testimony by NewYorkCountryLawyer · · Score: 4, Insightful
    You do not understand the law, or what the case was about, or what the deposition was about, or what the motion is about. The deposition was about what his methods were, and whether they were sufficiently "reliable" under the Daubert line of cases. His deposition testimony negated any possibility of his testimony being admissible at trial because he flunked all of the "reliability" standards.

    Your comment makes no sense. He was not "supposed to investigate" anything; he was "supposed to" testify about the investigation that was done three (3) years earlier.

    As to whether he was "out of his area", he probably was... but that's not my fault, that's his, for pretending to be something he's not, and it's the RIAA's, for inducing the man to pretend to be something he's not. While I may have been asking him things he couldn't answer, they were not irrelevant to his report and his proffered testimony; they were directly relevant to what he falsely claimed.

    I'm sorry to have to tell you that your knowledge of law is quite limited. There is no "prosecution"; this is a civil case. There is no concept of "reasonable doubt" in a civil case.

    Yes his testimony is helpful to defendant. But this is not a game; this is a federal trial where one side is suing someone for tens of thousands of dollars. Under clear standards of law his testimony is inadmissible and must be excluded. I would be a pretty dumb lawyer if I allowed the RIAA to bring this guy anywhere near a courtroom.

    The RIAA says he is their only witness to copyright infringement.

    They used the same expert in all the cases.

    And it turns out his testimony would be inadmissible at trial.
