Content authorisation system

摘要

In method and system for authorising multiple devices 56 and multiple content providers 52 in a content provision system, each content provider is issued with a content provider authorisation certificate, and each user device (e.g., video on demand (VOD) television set-top box (STB)) is issued with a user device authorisation certificate, the two certificates for coming from a common source. A determination is then made as to whether each content provider and each user device is authorised to participate in the content provision system (e.g., using software applications (apps) 302) via a mutual exchange and comparison of the certificates between respective content providers and user devices. The content provider and user device authorisation certificates may be rooted in a common root (e.g., self-signed) certificate; a root certificate authority may be identified, with delegated intermediate certificate authorities. Authorisation certificates (unique) can be signed or generated using a root certificate private key. Public key infrastructure (PKI) and public key certificates, OK, may be employed; revoked certificates may be listed.
