New patents are issued by the USPTO on Tuesdays. Both of today's Spotlight Patents continue the theme of blockchains (distributed ledgers, smart contracts) and rights management broadly construed. Assigned to EMC, the first patent addresses decentralized identities for cross-enterprise authentication and/or authorization. Assigned to USAA, the second patent addresses techniques for storing information concerning rights and liabilities or other records on distributed ledgers.
10,587,413, "Decentralized identities for cross-enterprise authentication and/or authorization," assigned to EMC.
At least one identity for a given entity of a first enterprise is established in accordance with a decentralized identity management system maintained in accordance with a distributed ledger. The identity of the given entity of the first enterprise and a set of attributes relating to the identity are defined by at least one cryptographically signed token file. The cryptographically signed token file is referenced in the distributed ledger enabling a second enterprise to authenticate and/or authorize the given entity in accordance with at least one of the set of attributes.
10,586,062, "Systems and methods to track, store, and manage events, rights and liabilities," assigned to United Services Automobile Association (USAA).
Aspects herein relate to storing information concerning rights and liabilities or other records on distributed ledgers. A method disclosed can include identifying a transferor blockchain associated with rights and liabilities for transfer from a transferor to an acquirer, identifying an acquirer blockchain associated with the acquirer, creating an interim blockchain including the rights and liabilities, generating entries to the transferor blockchain removing the rights and liabilities, and generating entries to the acquirer blockchain adding the rights and liabilities. Another method disclosed can include identifying a critical record of a party, identifying a blockchain associated with the party, and generating an entry on the blockchain associated with the critical record, the entry having permissions related to at least the party.
