Shift key breaks CD copy locks

In a paper published on his Web site this week, Princeton Ph.D. student John Halderman explained how he disabled a new kind of copy-protection technology, distributed as part of a new album by BMG soul artist Anthony Hamilton.

Under normal circumstances, the antipiracy software is automatically loaded onto a Windows machine whenever the Hamilton album is run in a computer's CD drive, making traditional copying or MP3 ripping impossible. However, simply holding down the Shift key prevents Windows' AutoRun feature from loading the copy-protection software, leaving the music free to copy, Halderman said.

The technique was confirmed by BMG and SunnComm Technologies, the small company that produces the anticopying technology. Both companies said they had known about it before releasing the CD, and that they still believed the protection would deter most average listeners' copying.

"This is something we were aware of," BMG spokesman Nathaniel Brown said. "Copy management is intended as a speed bump, intended to thwart the casual listener from mass burning and uploading. We made a conscious decision to err on the side of playability and flexibility."
