Abstract:
A method, apparatus, and system for proactive forced renewal of content protection implementations in devices. The method includes, on a first substantially periodic basis, automatically pushing a new content protection implementation to a device that contains an existing content protection implementation; wherein the existing content protection implementation comprises (a) existing software for presenting protected content and (b) an existing key to facilitate presentation of protected content; and wherein the new content protection implementation comprises a new key to supersede the existing key for facilitating presentation of protected content. On a second substantially periodic basis, the method includes automatically pushing revocation data to the device, the revocation data to identify a plurality of revoked keys, each revoked key of the plurality of revoked keys comprising a key that has been superseded by the new key of the new content protection implementation.
