The files will be wrapped in an encryption system that allows content owners to determine how they can be used. This system will supposedly remove the MP3s from Napster, replacing them with a proprietary digital-rights management system. Yet such a digital-rights management system has not yet been developed. And there is no way to make money off these transactions. In addition, any encryption scheme for tagging files across the Napster network will likely be broken.
Cryptographers say all digital-rights management systems are eventually defeated.
It s not even clear that Napster is going to survive possible huge fines for copyright violation. But even if Judge Patel creates an injunction that forces Napster, or the record companies, to police for infringing materials, the music industry is ultimately fighting a losing battle against unauthorized copying. It s alienating its own customers and possibly provoking widespread civil disobedience, even if it wins in court. Ann Harrison is a technology reporter in San Francisco.
