Publication number: 20240080445Abstract: Methods and systems related to authoring and acquiring digital rights management (DRM) licenses are disclosed. For example, a computing device may generate or author a digital rights management license for a content asset that includes one or more usage restriction rules. A usage restriction may limit the maximum display resolution for a content asset. Another device may then receive the license and process the one or more usage restrictions prior to presentation of the content asset to a user.Type: ApplicationFiled: November 13, 2023Publication date: March 7, 2024Inventors: Kyong Park, James W. Fahrny

Publication number: 20240022430Abstract: Systems and methods are described that relate to authentication and/or binding of multiple devices with varying security profiles. In one aspect, a first device with a higher security profile may vouch for the authenticity of a second device with a lower security profile when the second device requests access for content from a content provider. The vouching process may be implemented by allowing the first device to overlay its digital signature on a registration request that has been signed and transmitted by the second device. The second device with the lower security profile may access content from the content provider or source for a predetermined time period, even when the second device does not access content through the first device.Type: ApplicationFiled: September 15, 2023Publication date: January 18, 2024Inventors: James W. Fahrny, Kyong Park

Patent number: 10848806Abstract: A technique for securely transferring content from a first device in a first layer to a second device in a second layer. In one embodiment, the first device is a device in a trusted domain and the second device is outside of the trusted domain. Transfer of protected content to another device may require authentication of the receiving device. A rights file which specifies the rights of the receiving device to use the protected content, according to its security level is also transferred. These rights may concern, e.g., the number of times the receiving device may transfer the protected content to other devices, the time period within which the receiving device may play the protected content, etc. The higher the security level of the receiving device, the more rights accorded thereto. A minimum security level requirement may be imposed in order for protected content to be transferred to a device.Type: GrantFiled: May 14, 2018Date of Patent: November 24, 2020Assignee: TIME WARNER CABLE ENTERPRISES LLCInventors: William L. Helms, John B. Carlucci, Michael T. Hayashi, James W. Fahrny

Patent number: 10461931Abstract: The disclosure relates to processing content with watermarks to generate watermarked versions. In some aspects, each version may be different. Groups of fragments may be combined to generate a unique stream by pulling fragments from two or more of the groups of fragments. Further, fragmenting may be performed before watermarking, and fragments may be pulled and watermarked upon request.Type: GrantFiled: July 26, 2017Date of Patent: October 29, 2019Assignee: Comcast Cable Communications, LLCInventors: John Leddy, James W. Fahrny, Allen Broome, Michael A. Chen

Publication number: 20190260720Abstract: A security system is disclosed in which a device-specific key value is provided to a security processing device, and then used to derive additional derived keys for use in secured communications. In response to identifying a compromise of the derived keys, the system can be instructed to derive new or replacement derived keys for use in the secured communications. In some embodiments, the security system can be used in a video reception device, to decrypt encrypted video content.Type: ApplicationFiled: December 6, 2018Publication date: August 22, 2019Inventors: James W. Fahrny, Pete Kuykendall, Nancy Davoust

Patent number: 10055553Abstract: A system and method are disclosed for creating a secure video content path, or a protected media content bus, within an unsecure personal computer. A portable security module, or electronic key safe, may be inserted into a personal computer that has different internal components for processing secure and unsecured content. The security module may establish a secure encrypted link with a secure video processor of the personal computer, and may use the personal computer's network interface to request authority to receive secured content. The security module may provide content keys to the secure video processor to access secured content received over an external network.Type: GrantFiled: March 29, 2016Date of Patent: August 21, 2018Assignee: Comcast Cable Communications, LLCInventor: James W.
