An anonymous reader writes "A Dartmouth professor's analysis of MediaSentry problems helped win a New Hampshire woman's RIAA music-download lawsuit. 'Since all of Plaintiffs' claims are based on the assumption that MediaSentry's software and computer configuration are trustworthy and free of errors, and this log clearly represents a failure of the MediaSentry software to perform the operation it claims to describe, the reliability and validity of the MediaSentry method should be questioned,' wrote professor Sergey Bratus in his report, dated May 30. 'In my opinion, these materials leave critical aspects of MediaSentry's evidence collection process undocumented. In my opinion, they express unwarranted assumptions regarding both software and network technologies involved, and attempt to create an illusion of evidence-supported certainty where it does not exist.'" The full report (PDF) is available online. It's worth noting that this victory was not the outcome of a court ruling; rather, a settlement was reached that did not require the defendant, Mavis Roy, to pay anything to the RIAA.
