Content Protection for Recordable Media (CPRM)
CPRM is a mechanism that ties a recording to the media on which it is
recorded. It is supported by some DVD recorders, but not by many DVD
players. Each blank recordable DVD has a unique 64-bit media ID etched
in the BCA. When protected content is recorded onto the disc, it can be
encrypted with a 56-bit C2 (Cryptomeria) cipher derived from the media ID.
During playback, the ID is read from the BCA and used to generate a key to
decrypt the contents of the disc.
If the contents of the disc are copied to other media, the ID will be absent
or wrong and the data will not be decryptable.
