Blockchains (smart contracts, distributed ledgers) and rights management broadly construed are the themes of today's Spotlight Patents. Assigned to Huawei, the first patent addresses techniques for copyright rights defense detection. Assigned to Northern Trust, the second patent addresses techniques for digital identity management and permission controls within distributed network nodes.
11,127,097, "Method, apparatus, and system for copyright rights defense detection," Huawei Technologies Co., Ltd. (CN).
A method, an apparatus, and a system for copyright rights defense detection are provided. The method includes: sending a metadata query request to a copyright handling apparatus; receiving a metadata query response that is sent by the copyright handling apparatus and that includes feature metadata; obtaining a rights-to-be-defended content feature corresponding to the feature metadata from a feature database; sending a license query request to a license processing apparatus; receiving a license query response that is sent by the license processing apparatus and that includes license information; and performing rights defense detection for a copyright based on the obtained rights-to-be-defended content feature and the license information. Rights defense detection can be performed for a copyright by any rights defense detection service apparatus.
11,128,467, "Systems and methods for digital identity management and permission controls within distributed network nodes," assigned to Northern Trust Corporation.
Embodiments disclosed herein provide systems and methods for digital identity management and permission controls within distributed network nodes. A network node may receive a request to generate a new digital identity record for an entity. The network node may retrieve a template based on an entity type; and receive information, reference documents, and biometric information for the new digital identity record. The network node may associate and store the received information to the data fields in the new digital identity record, generate respective one directional cryptographic hashes of the reference documents and the biometric information, and store the hashes in the new digital identity record while storing the reference documents and biometric information in a non-blockchain repository. The network node may generate a digital identity record block for the new digital identity record, encrypt the digital identity record block, and append the encrypted block to the latest valid blockchain.
