Anchor point for digital content protection
Abstract:
Digital rights management (DRM) can be implemented through use of an anchor point based digital rights management system. In one embodiment, a device may comprise an anchor point circuit including a memory and a processor. The processor may be configured to receive a title key from a digital content provider, the title key used to encrypt a digital property to produce an encrypted digital property. The processor may be further configured to generate a binding key, encrypt the title key with the binding key to produce a title pre-key, and store the binding key in the memory. In another embodiment a system may comprise an interface configured to communicate with a content provider, and an anchor point circuit configured to bind a digital property received from the content provider to the anchor point circuit such that the digital property can only be used in conjunction with the anchor point circuit.
