A method for verifying authenticity of a monitoring signal, wherein a multitude of actuators are employed to impact with individual signals on a physical environment, wherein said individual signals originating from said actuators are directed to said physical environment, wherein at least one sensor device observes said physical environment in such a way that said sensor device records the monitoring signal representing a combined impact of said individual signals on said physical environment, wherein said monitoring signal is compared with an expected signal in order to determine a degree of similarity between said monitoring signal and said expected signal, wherein said expected signal is computed on the basis of predetermined templates, wherein said templates are previously generated in a secret initialization procedure in such a way that the impact on said physical environment for each of said individual signals is separately recorded as template by said sensor device. Furthermore, a corresponding monitoring system is disclosed. |
