DVD Copy Protection: Take 2
The next generation of technology won't have a Hollywood ending
By Tekla S. Perry
In 1999, a 16-year-old Norwegian high school student took on the
motion-picture industry and won. The teenager, Jon Johansen, wrote
software that decrypted the Content Scrambling System (CSS) that
rearranges the bits on prerecorded DVDs to prevent the discs' being
played back on unauthorized hardware. Until Johansen wrote his software
utility, which he called DeCSS, you could copy the bits from a DVD to
your computer hard drive, but because those bits were scrambled, you
couldn't play a movie from those copied bits.
