ABSTRACT:
A method for monitoring communication includes intercepting one or more communication links, which are part of a communication system that includes a plurality of the communication links. Data content that is carried by the one or more communication links is decoded. First and second mathematical fingerprints related to the one or more intercepted communication links are computed by evaluating statistical characteristics of the data content decoded from the one or more communication links. The first and second fingerprints are compared to produce a matching result, and a predefined action is performed with respect to the one or more communication links responsively to the matching result.
