ABSTRACT:
Entertainment content is stored in a memory. The content can be audio or video or both. According to an aspect, encryption is keyed to the disc contents to produce a cryptographically created value. That cryptographically created value is based on the content on the memory along with the cryptographic operation. The cryptographic value can be used to determine if data on the memory is valid. One aspect of the memory can be an optical disc. Another aspect carries this out only for recorded discs and does not do this for prerecorded discs.
