New patents are issued by the USPO on Tuesdays. Both of today's Spotlight Patents concern aspects of blockchain(distributed ledger, smart contracts) and digital rights management broadly construed. Assigned to Xerox, today's first patent addresses techniques for a secure revisioning auditing system for electronic document files. Assigned to Forcepoint, the second patent addresses techniques for managing blockchain access to user profile information.
10,129,032, "Secure revisioning auditing system for electronic document files," assigned to Xerox.
Methods and systems for providing secure recording of revisions made to electronic documents, using secure methods to validate the recorded changes, are disclosed. An electronic device making a change to an electronic document can transmit the change to the network. An audit log chain is residing on the network and shared among all the nodes on the network. A node on the network can verify a change of document made by other nodes and add a new block to the chain using one-way hashes, making the chain resistant to tampering. If an invalid block is detected, the system can send an auditing alert to the network. The audit log can be strongly resistant to tampering, providing reliable evidence for use in audit compliance, investigations, and business or court record keeping.
10,129,269, "Managing blockchain access to user profile information," assigned to Forcepoint, LLC.
A method, system and computer-usable medium for generating a user behavior profile, comprising: monitoring user interactions between a user and an information handling system; converting the user interactions and the information about the user into electronic information representing the user interactions; generating a unique user behavior profile based upon the electronic information representing the user interactions and the information about the user; storing information relating to the unique user behavior profile within a user behavior profile repository; and, storing information referencing the unique user behavior profile in a user behavior blockchain.
