- 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.
