Anchor point-based digital content protection with an escrow anchor point

摘要

Digital rights management (DRM) can be effectively implemented through use of an anchor point and binding records in a user domain and backed up through use of an escrow anchor point and an escrow binding record in an anchor point based digital rights management system. An escrow binding record provides additional functionality and reliability to a DRM system by allowing a user to use of digital content even after an access device has been lost or compromised.
