Abstract
A method of authenticating devices utilizes a central ledger distributed to a plurality of local systems includes storing a unique identifier locally on each device, modifying a central ledger to include an entry associated with the unique identifier and communicating the central ledger to a plurality of local systems for storage. To authorize a device, the local system receives a unique identifier from a connected device and searches the local ledger to verify/authenticate the validity of the connected device for use in the local system. The local system may then modify an entry in the local ledger associated with the unique identifier to reflect use and communicate the modified local ledger from each of the plurality of local systems to the centralized system. The central system then modifies the central ledger based on the received local ledger and communicates the modified central ledger to a local system.
