CD protection beaten in the press of a button

A student from Princeton University in the US has published instructions for disabling the new anticopying measures being tested on CDs from record label BMG - and they're as simple as holding down a computer's Shift key.

In a paper published on his website this week, Princeton PhD 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 from copying.

A BMG spokesman said: "This is something we were aware of. 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."

The ease with which Halderman and others have disabled BMG and SunnComm's latest copy-protection techniques illustrates the delicate balance that record labels and technology companies are trying to strike in protecting content without angering listeners.
