The invention provides a method to detect tampering of data. The method includes constant acquiring of measurement raw data in a sensor unit; processing of measurement raw data of a defined time interval in a metrology unit, obtaining first measurement results; at least one of storing of the first measurement results and transmitting of the first measurement results to an authority at defined time instances via a communication channel; at least one of storing of a defined fraction of measurement raw data and transmitting of a defined fraction of measurement raw data to the authority in a random manner via the communication channel; processing of the measurement raw data of the defined time interval at the authority, obtaining second measurement results; and comparing the first and second measurement results of a time interval.
