  • Systems and methods for digital authentication of usage data of an automation plant
    Patent number: 12204305
    Abstract: A system includes a first module configured to collect automation plant-related data that include at least operating data, and to generate based on the operating data manipulation-proof usage data which are then transmitted to a second module configured to determine at least a part of the manipulation-proof usage data, to form a checksum from the at least one part of the manipulation-proof usage data, to transfer the checksum to at least one node of a distributed ledger network, and to store the manipulation-proof usage data in an area outside the distributed ledger network. A third module participates in the distributed ledger network and is configured to obtain the manipulation-proof usage data from the area and to check the correctness of the manipulation-proof usage data by forming a checksum.
