New patents are issued by the USPTO on Tuesdays. This week's Spotlight Patents continue the theme of blockchains (smart contracts, distributed ledgers) and rights management broadly construed. Assigned to Visa, the first of this week's Spotlight Patents addresses techniques for creating multiple records based on an ordered smart contract. Assigned to IBM, the second patent addresses techniques for high precision timestamps in blockchain.
10,762,217, "Systems and methods for creating multiple records based on an ordered smart contract," assigned to Visa.
A method for creating a smart contract detailing an ordered set of events is disclosed. A smart contract can include information about multiple events and responses for each event. The events and response can be arranged in a predefined order. The responses can include adding new records to a blockchain.
10,764,070, "High precision timestamps in blockchain," assigned to IBM.
An example operation may include one or more of receiving, by a document server, a hash of data generated by an author registered with a blockchain, sending, by the document server, the hash of the data to a timestamp authority (TSA) to be time stamped, receiving, by the document server, a timestamp reflecting when the hash of the data was received by the TSA and forwarding the timestamp to the author, receiving a combination of the hash of the data and the timestamp (time/hash) signed by the author and forwarding the time/hash to the blockchain, receiving, by the document server, the time/hash signed by the TSA, and forwarding the time/hash signed by the TSA to the blockchain.
