Patent ID: 8831217

Claim:
A storage device configured to provide content to a player system for rendering of the content, said storage device comprising: a storage medium comprising a user area that is accessible by the player system and a non-user area that is not accessible by the player system; and a controller comprising a cryptographic module providing a hardware root of trust and a secured memory, wherein the controller is configured to: authenticate the player system; establish a secured communication channel with the player system based on the authentication; provide, to the player system, a first cryptographic key, wherein the first cryptographic key is unique to the storage device, the first cryptographic key based at least partly on defect information of the storage medium and cryptographic data stored on the non-user area; provide, to the player system, a second cryptographic key that is associated with the content, wherein the second cryptographic key is based at least partly on cryptographic data previously obtained, over a communication network, from an audit system distinct from the player system; and provide, to the player system, the content in encrypted form from the user area of the storage medium, wherein the content is accessible based on a cryptographic combination of the first cryptographic key and the second cryptographic key.
