Zusammenfassung:A method to detect tampering of data includes constant acquiring of raw measurement data in a sensor unit. The raw measurement data of a defined time interval is processed in a metrology unit to obtain first measurement results. The first measurement results are transmitted to an authority at defined time instances via a communication channel. A defined fraction of raw measurement data is transmitted to the authority in a random manner via the communication channel. The raw measurement data of the defined time interval is processed at the authority to obtain second measurement results. The first and second measurement results of a time interval are compared.
