A technology battle is raging in UMG v. Lindor in Brooklyn over whether the RIAA's investigator, SafeNet (formerly known as MediaSentry), which has produced certain *txt printouts, now needs to disclose its digital files, validation methodology, testing procedures, failure rates, software manuals, protocols, packet logs, source code, and other materials, so that the validity of its methods can be evaluated by the other side. SafeNet and the RIAA say no, the information is "proprietary and confidential". Ms. Lindor says yes, if you're going to testify in federal court the other side has a right to test your evidence. A list of what is being sought is here (pdf). MediaSentry has produced 'none of the above'. "Put up or shut up" says one commentator to MediaSentry. What do you say?
