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 & VCR, 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.
Disc contents cannot be copied to other media.
❖
You cannot record.
The disc is protected.
