摘要： Systems and methods for synchronized key derivation across multiple conditional access servers are disclosed. In one embodiment, a method for synchronized key derivation to provide playback devices with derived keys for decrypting content includes receiving a request for a first derived key that includes a first asset identifier than identifies a piece of content and a first playback position within the content, determining a first content key starting position and first derived key starting position within the content using the first playback position, where the key starting positions precede the first playback position, determining whether a first content key associated with the first asset identifier and first content key starting position is stored, retrieving the first content key using the first asset identifier and first content key starting position, generating a first derived key using the first content key and first derived key starting position, and sending the derived key.

摘要： Systems and methods are described for imperceptibly embedding information by overwriting original video content with other content from a bitstream In a number of embodiments, the replacement of original content is efficiently implemented by referencing other information in the bitstream, also called reference content. One embodiment of the invention includes analyzing the compressed bitstream using a preprocessor to identify locations that can be imperceptibly modified, generating at least one piece of replacement data for each identified location using the pre-processor, selecting pieces of replacement data using an embedding device, and embedding the payload information in the compressed bitstream by using the embedding device to overwrite at least a portion of the compressed bitstream with the selected replacement data.

摘要： In a network user authentication system, a network user is identified for authentication purposes using the unique identifier for a dedicated physical communication line associated with the building in which the network user is located or a digital certificate which is associated with a secure component or communication line physically attached to a building. An authentication server initially verifies the identification of the dedicated communication line to be associated with a network service subscriber or issues a unique digital certificate to be associated with the dedicated communication line for authentication purposes. The digital certificate may be stored in a building gateway or in an edge site module which is connected to the secure components of a plurality of buildings and stores unique digital certificates for each building.

摘要： A video shop access system allows consumers to receive information on title inventories available at local video shops in the consumers' geographical area through their home or wireless media servers. A video shop data center receives title information on inventory available at the local video shops and stores the title information in an inventory data base. On receipt of a request from a consumer's media server, a video shop user interface is provided to the media server and displayed on an associated user display device, the user interface providing a link to the stored title inventories. The consumer can select and order titles through the interface, and orders are forwarded by the data center to the appropriate local video shop, which delivers a physical copy of the title to the requesting consumer.

摘要： In a method of monitoring the distribution of digital content files, transaction information regarding transfer of a selected digital content file stored at a distribution provider to a distributor is obtained by a transaction monitoring module and analyzed to detect whether the transfer is valid and associated with a valid security device for the transfer. A report is generated if a security breach is detected and is used by a piracy insurance provider to assess risks in connection with a piracy insurance policy issued to the distribution provider. The security device may be an encrypted watermark or digital signature using a digital certificate associated with the distributor to which the file is transferred.

摘要： Systems and methods for decentralized certificate hierarchy using a distributed ledger to determine a level of trust in accordance with embodiments of the invention are disclosed. In one embodiment, an loT (internet of things) access controller device receives a request for permissions on a local network from an loT device, where the request includes a digital certificate chain, where the digital certificate chain includes a digital certificate associated with the loT device and one or more digital certificates in a hierarchy, scans a distributed certification ledger (DCL) for past transactions related to the digital certificates to: retrieve transaction data including information characterizing past usage of any of the digital certificates, and information about transactions including the digital certificate that have been posted by another entity, calculate a trust level, determine whether to proceed with granting the requested permissions, grant the requested permissions when the determination is affirmative.
