A Princeton graduate student said on Monday that he has figured out a way to defeat new software intended to keep music CDs from being copied on a computer -- simply by pressing the Shift-key.

In a paper posted on his Web site late Monday, John Halderman said the MediaMax CD3 software developed by SunnComm Technologies Inc. could be defeated on computers running the Windows operating system by holding down the Shift key, disabling a Windows feature that automatically launches the encryption software on the disc.

Halderman said the protection could also be disabled by stopping the driver the CD installs when it is first inserted into a computer's drive.

Computers running Linux and older versions of the Mac operating system are unable to run the software and are able to copy the disc freely, he said.

The CD in question, Anthony Hamilton's "Comin' From Where I'm From," was released by BMG's Arista label in late September. Music retailers praised the release, which BMG touted as a breakthrough in the industry's efforts to prevent music piracy.
