New pending patent applications are published on Thursdays by the USPTO. Today's Spotlight Applications continue the theme of blockchain (distributed ledger, smart contracts) and digital rights management broadly construed. Assigned to Comcast, the first application discloses techniques for managing device associations. Assigned to IBM, the second application discloses techniques for authorizing account access via blinded identifiers.
20190020648, "Systems and methods for managing device association," assigned to Comcast.
A method and system for managing device association and access is disclosed. Some embodiments may comprise receiving, from a user device, a request to access a network device. The request may comprise a public key of the user device. The request may comprise a digital certificate, wherein the digital certificate may comprise the public key of the user device. A distributed database address of the user device may be determined by applying a deterministic function to the public key of the user device. A distributed database entry may comprise the address of the user device. A distributed database entry may be generated, wherein the distributed database entry may comprise the address of the user device. Based on the address of the user device, access to the network device may be granted to the user device.
20190020468, "Authorizing account access via blinded identifiers," assigned to IBM.
An example operation may include one or more of receiving a new identifier from a user device associated with a user account, creating a hash based on the new identifier, comparing the hash to a hash value associated with one or more identifiers stored in a blockchain, identifying a match of the hash and the hash value associated with the one or more identifiers, authorizing the user account, responsive to identifying the match of the hash and the hash value associated with the one or more identifiers, and deleting the hash, the new identifier, and the hash value associated with the one or more identifiers stored in the blockchain responsive to authorizing the user account.
