Abstract
A method and system with means for preventing unauthorized monitoring of a local conference room in which a local conferencing system is located comprising generation of a deterministic sound signal, and loading the deterministic sound signal on a first loudspeaker connected to, or integrated in the conferencing system, detecting the deterministic signal by analyzing a microphone signal picked up by a microphone connected to, or integrated in the conferencing system, and transferring the conference system into a security mode, if the deterministic signal is not detected.
