  • Methods, systems, and computer readable media for verifying calibration information using a distributed ledger
    Patent number: 10797873
    Abstract: A method that occurs at a distributed ledger system includes receiving a request for calibration information associated with a first unit identifier (UID) and determining one or more UIDs associated with the first UID. The method also includes, for each of the first UID and the one or more UIDs: determining, using one or more access control rules, that a requester is permitted access to the calibration information associated with a respective UID; obtaining at least one access security key for accessing the calibration information; obtaining, from at least one block of a first distributed ledger, a digital signature associated with the calibration information associated with the respective UID; using the at least one access security key to decrypt and access the calibration information associated with the respective UID; and verifying, using the digital signature, the calibration information associated with the respective UID.
