Rights enforcement and usage reporting on a client device
Abstract:
An integrity hash is obtained of rights information stored at a client device. The rights information is associated with content stored at the client device. The integrity hash is encrypted using a client device key to generate an encrypted hash. The client device key is externally inaccessible from the client device. The encrypted hash is stored on the client device.
