Anchor point-based digital content protection
Abstract:
Digital content protection can be effectively implemented through use of an anchor point and binding records in a user domain. An anchor point domain may include a secure anchor point, and data storage to store digital property instances and rights objects. The secure anchor point may be configured to receive a title pre-key from the rights object and use a binding key to decrypt the title pre-key to yield a title key. The binding key may include data uniquely associating the encrypted digital property instance with the secure anchor point.
