Flaws in New CD Copy Protection

Analysis of the MediaMax CD3 Copy-Prevention System, by John A. Halderman:

“MediaMax CD3 is a new copy-prevention technique from SunnComm Technologies that is designed to prevent unauthorized copying of audio CDs using personal computers. SunnComm claims its product facilitates “a verifiable and commendable level of security,” but in tests on a newly-released album, I find that the protections may have no effect on a large fraction of deployed PCs, and that most users who would be affected can bypass the system entirely by holding the shift key every time they insert the CD.”

BeSpacific: “No one better has her finger on the pulse of the legal information world than Sabrina Pacifici, law librarian and author of the blog BeSpacific,” writes blogger Robert Ambrogi. “Launched in 2002, BeSpacific is one of the longest-running legal blogs and, remarkably, Sabrina seems more prolific today than ever. She posts multiple items every day, covering the gamut of law, technology and knowledge discovery and topics ranging from cybersecurity to legal research to government regulation to civil liberties to IP and more. For me, BeSpacific is one of my daily must-reads and has been for 14 years straight.”
