New pending patent applications are published on Thursdays. Both of today's Spotlight Applications concern aspects of blockchain (distributed ledger, smart contracts) and digital rights management broadly construed. The first application discloses techniques for systems that integrate with a blockchain to provide for certification and verification of the origin and integrity of digital data as it is created, edited, and/or released. Assigned to Sensoriant, the second application discloses techniques for consistency and consensus management in decentralized and distributed systems.
20190228133, "Systems and methods of digital content certification and verification using cryptography and blockchain," assigned to Nasdaq, Inc.
A verification computer system is provided that provides for content certification and verification using cryptography and a blockchain.
20190229918, "Consistency and consensus management in decentralized and distributed systems," assigned to Sensoriant, Inc.
A method for achieving consensus amongst a distributed and decentralized set of computers, devices or components in a network interacting via messaging is presented. The method does not rely on the availability of an overall ledger that is consulted for every interaction. Rather, the interacting components communicate directly with each other via messages that contain proofs of consistency that may be used to achieve local consistency amongst the interacting components. Local consistency guarantees global consistency. For regulatory and record keeping purposes, use of an overall ledger may be contemplated for regulatory and record keeping purposes. The latter may be updated by the interacting devices via an asynchronous updating mechanism.
