FIELD: information technology.
SUBSTANCE: invention relates to communication engineering and can be used to protect information processed by a technical means having a video system operating on the basis of DVI, VGA, Display Port, HDMI and similar standards, from leakage of information on a channel of secondary electromagnetic radiation and pickup (SEMRP). In order to achieve the technical result in the method consisting in the vehicle formation on the additional information input/output port, to which the information input/output device of the structured non-information signal is connected, wherein as an information input/output port, where the vehicle generates a non-information four-channel signal, an additional video port of the vehicle is used, as an information input/output device an information security device is used.
EFFECT: eliminating human factor influence on the process of technical protection of information from leakage through the SEMRP channel and improving efficiency of using interference energy due to its adaptivity on the spectrum width, level and time of radiation relative to the informative signal.
