New pending patent applications are published by the USPTO on Thursdays. Both of today's Spotlight Applications concern aspects of blockchain (distributed ledger, smart contracts) and digital rights management broadly construed. Assigned to PencilData, the first application discloses techniques for dynamically generated smart contracts. Assigned to Paypal, the second application discloses an encryption based shared architecture for content classification.
20190188399, "Dynamically generated smart contracts," assigned ot PencilData, Inc.
A document source that generates, maintains, or distributes electronic documents receives a policy that defines for an electronic document, a set of guidelines for access to the electronic document. Based on the policy, the document source generates a smart contract including a set of rules that when executed change a user's access rights with respect to the document and publishes the smart contract to a blockchain. An oracle is triggered to input a user request related to an electronic document to the smart contract. Based on execution of at least one of the rules, the document source receives an indication of an access right for the user and enforces the access right with respect to the electronic document.
20190188702, "Encryption based shared architecture for content classification," assigned to PayPal, Inc.
Encryption operations using private and public cryptographic signature keys may be used to facilitate secure and uniquely identifiable audit records relating to website content classification. Blockchain may be used to facilitate collection, storage, and sharing of encrypted audit records. Based on shared encrypted information (e.g. from the blockchain or elsewhere) a content evaluation consensus may be formed. Collections of encrypted audit records may be processed and results of the processing may also be shared via the blockchain. Subsequent operations can include sharing of the processing results.
