U.S. Patent 10964145 was awarded to Sensormatic Electronics, LLC on March 30, 2021 and is entitled “Access control system using blockchain ledger.” The first named inventor is Ashwin Reddy Lingannagari of Billerica, MA. The abstract contains an overview of the patent disclosure:

A distributed transaction ledger (e.g. blockchain) is used to control access through access points in an access control system. During normal operation, access control devices (e.g. system controllers and door controllers) generate and broadcast transaction information to a validation network. The validation network maintains a distributed transaction ledger for the access control system, for example, by validating and distributing the transaction information across the validation network according to predetermined consensus criteria. The devices perform access control functions based on transaction information retrieved from the transaction ledger. Door controllers receive identification information from user devices (e.g. identification badges, mobile computing devices) and send the identification information to the validation network. A predetermined number of responding nodes generate verification information based on authorization information in the transaction ledger. If a predetermined proportion of the responding nodes indicate that the occupant is authorized, access is granted by the door controller. Link to Full Patent
