Abstract
A method for verifying authenticity of a monitoring signal includes employing a multitude of actuators to impact a physical environment with individual signals, wherein the individual signals originate from the actuators and are directed to the physical environment; observing, via at least one sensor device, the physical environment so as to record the monitoring signal, wherein the monitoring signal represents a combined impact of the individual signals on the physical environment; and comparing the monitoring signal with an expected signal to determine a degree of similarity between the monitoring signal and the expected signal, wherein the expected signal is computed on the basis of one or more predetermined templates, wherein the predetermined templates are previously generated in a secret initialization procedure in such a way that the impact on the physical environment for each of the individual signals is separately recorded as a template by the sensor device.
