Something for the Technically Inclined: Professors Dissect RIAA's MediaSentry "Investigations"

A recently obtained English translation of the opinion of the Amsterdam Court of Appeal in Foundation v. UPC Nederland, agrees with the lower court decision that the MediaSentry investigation by Tom Mizzone was an insufficiently reliable basis to warrant directing Dutch ISP's to turn over confidential customer information to the RIAA's Netherlands counterpart: "neither the affidavits nor the cross-examination of Mr. Millin pro[...]vide clear and comprehensive evidence as to how the pseudonyms of the KaAaA or iMesh users were linked to the IP addresses identified by MediaSentry. No evidence was presented that the alleged infringers either distributed or authorized the reproduction of sound recordings. They merely placed personal copies into their shared directories which were accessible by other computer users via a P2P service." The appeals court agreed with the independent experts report of Prof. Henk Sips and Dr. Johan Pouwelse of the Parallel and Distributed Systems research group at Delft University of Technology that MediaSentry's Tom Mizzone had not taken the "necessary precautions" in conducting his 'investigation' and that his investigation was 'limited' and 'simplistic', failing to "resolve... relevant technical problems such as superpeer hopping, NAT translation, and firewall relaying....[failing to implement] "actual complete file transfer....simply [taking] filenames at face value and ...[failing to make] any correction for pollution on Kazaa [despite] [p]ollution levels [on Kazaa which] can be as high as 90% for some files....[not being aware of] the limitations of Kazaa in file searching. Not many of the 2,499,121 users online would be able to see the mentioned 736 files. Reliable global searching in P2P file sharing networks is still an unsolved problem. Only users connected to the same Kazaa Superpeer are guaranteed to see these files when Kazaa operates properly (roughly 100 to 150 users as measured by Prof. Keith Ross)....[failing to take] computer hygiene precautions ..... The collected evidence of the spacemansam@KaZaA alias [query] contains multi-peer downloading contamination. Therefore, it is difficult to establish the contribution of the various IP-addresses. It is possible that some IP-addresses contributed 0 Bytes to an actual download, thus there was only involvement and no actual contribution". The Netherlands litigation recently came to the fore recently in UMG v. Lindor, a United States case, in which the RIAA is trying to prevent Ms. Lindor's attorneys from seeing the MediaSentry agreements spelling out the "instructions", "parameters", and "processes" of Mr. Mizzone's investigation, and Ms. Lindor's attorneys argue that the agreements are necessary for a proper deposition and cross-examination of Mr. Mizzone.
