<p>A system, method and device for adding security features associated with a hardware-based root of trust to a system for playing encrypted media content is described. The system allows for traceability of content linked to or derived from a decrypting element within the system should its decryption capabilities be made available to a third party without authorisation, thereby allowing for at least the decryption element to be revoked.</p> |
