Researchers claim music defense inept
LOS ANGELES — A group of researchers claims to have defeated four technologies being developed to prevent computer users from listening to copyrighted music for free.
"I expected some would have fallen," said Talal Shamoon of the initiative. "This is part of an empirical process to get the best technology."
A Secure Digital Music Initiative representative said Monday that it was too early to verify the researchers' claims, but that complete circumvention of all four security schemes was a "fairly low probability event." He said that even if the technologies were defeated, it would not prevent the group from devising strong and effective security measures.
In September, the group issued a public challenge and offered a prize to anyone who could break or hack various security measures designed to protect files from being improperly copied or distributed. Four of the measures — each devised by a different technology company — involved an invisible watermark that could be detected by a digital music player. Two other measures used different technology.
Researchers at Princeton University, Xerox PARC and Rice University said they were able to remove invisible security measures placed on four music files by the Secure Digital Media Initiative — a group of 200 music, telecommunications and consumer electronic companies. Any reasonably sophisticated computer pirate intent on illegally distributing copyright music files could do the same, the researchers said. The claim, if true, strikes at the heart of efforts to protect copyrights and prevent people from listening to music for free using technology such as Napster.
1 believe all four of these schemes would have been cracked by pirates if they had been deployed," said Edward Felten, an associate professor of computer science at Princeton.
