  2. Copy protection and access control • Current content protection methods are designed for audiovisual content (CSS, CPRM/CPPM, VCPS, AACS,…) only and available for dedicated media types. • SecurDisc is a mechanism to protect sensitive data from copying and accessing on recordable optical media and is not bound to any dedicated media type. Recording can be performed on standard optical media without any pre-recorded area.

  3. B. General • Both copy protection and access control are enabled by encrypting the data that is written to the media such that only when the encryption key is known this will allow the drive to deliver the correct data. The encryption key is derived either from a user pass phrase, the Disc Unique ID (DUID) or both and combined with a shared secret known only to authorized applications. This share secret can be revoked in case an application is compromised.
