Authentication module for sensor data

An authentication module for a time series of sensor data, comprising:

• at least one data interface which can be connected to at least one sensor;
• an authentication interface and an authentication logic, which is coupled to the data interface and the authentication interface, wherein the authentication logic is implemented by a computer processor by accessing instructions stored on a non-transitory computer-readable storage medium configured to cause the computer processor to:
• receive at least one data set via the at least one data interface from at least one sensor,
• form one or more compressed products from one or more received data sets,
• create an authentication which contains the compressed products and respectively contains a reference to the associated data set, or at least a part of the associated data set,
• receive and store authentications from other authentication modules or include them in the authentication, wherein these other authentication modules are external to the authentication module,
• output the authentication via the authentication interface;
• wherein at least one of the other authentication modules comprises:
• at least another data interface which can be connected to at least another sensor;
• another authentication interface and another authentication logic which is coupled to the other data interface and the other authentication interface, wherein the other authentication logic is configured to:
• receive another data set via the other data interface from the other sensor,
• form another compressed product from the other data set,
• create another authentication which contains the other compressed products and respectively contains another reference to the associated data set, or at least a part of the associated data set, and
• output the other authentication via the other authentication interface.
