HOWTO make a DRM CD
Alex Halderman, one of the Princeton researchers who's been doggedly revealing the tricks, nastiness, cheating and lies in the Sony DRM Debacle, has published a detailed HOWTO explaining how to make your own malicious "industrial strength" DRM CD, just like Sony's. The perfect project for your holiday break!LinkYou added the extra track (shown in yellow) when you edited the disc image in step 4. This simple change makes the audio tracks invisible to most music player applications. It’s not clear why this works, but the most likely explanation is that the behavior is a quirk in the way the Windows CD audio driver handles discs with multiple sessions.
For an added layer of protection, the extraneous track you added to the disc is only 31 frames long. (A frame is 1/75 of a second.) The CD standard requires that tracks be at least 150 frames long. This non-compliant track length will cause errors if you attempt to duplicate the disc with many CD drives and copying applications.
