JVC has announced that it will use a CDROM copy protection scheme based on the collaboration between itself and a Japenese company Hudsonsoft. The scheme called the 'Root', records an encryption key when a CDROM is created in such a way that an error is generated when any attempt is made to playback software from copied disks.

It will be built into CDRWs so that copying to CD-R/RWs cannot circumvent it. The technology prevents encryption keys being read when copied disks are played back, and JVC hopes to sell mastering units incorporating the new technology to other manufacturers. The same technique can also be used to prevent copying of DVDs to any other media.
