Abstract
A method, apparatus and system for employing a secure content protection system is disclosed. In one embodiment, a certificate having a unique device identification associated with a first device is received, and, at a second device, a revocation list having unauthorized device identifications is received. The unique device identification is incrementally compared with the unauthorized device identifications of the revocation list, and media content is transmitted from the second device to the first device, if the unique device identification is not matched with the unauthorized device identifications of the revocation list.
Claims18
A method comprising:
- receiving a certificate having a unique device identification associated with a first device;
- receiving, at a second device, a revocation list having unauthorized device identifications;
- incrementally comparing the unique device identification with the unauthorized device identifications of the revocation list;
- and
- transmitting media content from the second device to the first device, if the unique device identification is not matched with the unauthorized device identifications of the revocation list.
An apparatus comprising:
- a first device coupled with a second device over a network of devices, the first device including a media content receiving device, and the second device including a media content transmitting device, wherein the second device to
- receive a certificate having a unique device identification associated with the first device;
- receive a revocation list having unauthorized device identifications;
- incrementally compare the unique device identification with the unauthorized device identifications of the revocation list;
- and
- transmit media content to the first device, if the unique device identification is not matched with the unauthorized device identifications of the revocation list.
A system to protect media content being communicated between devices over a network of devices, the system comprising:
- a first device coupled with a second device over the network of devices, the first device including a media content receiving device, and the second device including a media content transmitting device, wherein the second device having a content protection system, the content protection system to facilitate
- receiving, at the second device, a certificate having a unique device identification associated with the first device;
- receiving, at a second device, a revocation list having unauthorized device identifications;
- incrementally comparing the unique device identification with the unauthorized device identifications of the revocation list;
- and
- transmitting media content from the second device to the first device, if the unique device identification is not matched with the unauthorized device identifications of the revocation list.
