1. A sensor control assembly to securely verify and calibrate a sensor of a manufacturing device utilized in a manufacturing process of a product, comprising:
a sensor of a manufacturing device,
a first processing unit adapted to provide a cryptographic checksum of first sensor data acquired by the sensor,
a distributed database adapted to receive the first sensor data, wherein the distributed database is protected against manipulation,
a second processing unit adapted to verify the first sensor data based on the cryptographic checksum,
a third processing unit adapted to determine a demand for calibration or reset based on a comparison of second sensor data acquired in a defined manufacturing condition and the first sensor data acquired during the manufacturing process,
wherein the second processing unit and third processing unit can be the same or different processing units;
wherein the distributed database or a data storage contained in the manufacturing device is adapted to execute a smart contract based on the sensor data;
wherein the smart contract defines one or more thresholds for a deviation detected by comparing the first sensor data with the second sensor data; and
wherein a calibration or a reset of the sensor is triggered in the event that a first threshold value of the one or more thresholds of the smart contract is exceeded by the deviation.
