Bertelsmann has tapped its in-house digital rights management subsidiary, Digital World Services (DWS), to create the security technology for the peer-to-peer service it is developing with controversial file-swapping site Napster, Billboard Bulletin reports. The technology will be the key element in launching the subscription version of the service that was announced by Bertelsmann and Napster last October.

DWS executive director of marketing Trish Naudon says that the division has a "conceptual demo" of how the security will work but that no prototype has been built. "The music file will be secured with a 'wrapper,' and the person receiving it will have to have a key to open it," Naudon says. DWS is working under Bertelsmann's tight summer deadline to deliver the technology.

The announcement comes on the heels of the Feb. 12 ruling by the Ninth Circuit Court of Appeals that Napster must determine a way to remove copyrighted material from its directory. The Ninth Circuit upheld a U.S. District Court's decision to grant a preliminary injunction and ruled that the file-sharing service violates copyright law.

However, DWS will not be involved in developing technology to fulfill the Ninth Circuit's order. "The court decision helped moved things along in our favor, but we're not involved in it," Naudon says.

In related news, the Recording Industry Association Of America (RIAA) and the National Music Publishers' Association (NMPA), plaintiffs in the copyright-infringement lawsuit filed against Napster in 1999, have submitted their recommendations for the modified injunction to the District Court.

In its decision last week, the Ninth Circuit called the injunction "overbroad" and ruled that it be amended. The RIAA/NMPA filing says the bodies will comply with the court's order to identify copyrighted works they believe should be removed from the Napster directory; it also offers other undisclosed recommendations for the injunction.
