Detection of Technical Causes for Data Leakage: Methods, Structure and Characteristics of Detection Aids

The destination and problems of search systems for detection of the electromagnetic radiation and pickup are formulated. A brief review of aids for data reading is given. The search system specifications are stated. Stages of the electromagnetic radiation and pickups detection are determined. The single-channel and two-channel approaches to detect within the controlled room the unauthorized setting of sources of the radiation and spurious pickup are synthesized. Structures of the hardware and software implementing these approaches are determined. Methods for the remote radio-monitoring of several rooms from the central post are presented. The system operation modes are described and experimental results are given.
