One of the most vulnerable issues in the technical protection of information is the acquisition of private or confidential data due to leakage through the optoelectronic channel. Today, the most promising area of protection of speech information from laser acoustic intelligence systems is development of passive protection methods. The work is devoted to the influence study of interior elements in the room on the protection of language information from LAIS, that can be implemented effectively and with minimal costs at the design stage in order to comfortably conduct confidential negotiations. On the basis of the conducted research, a systematic approach to determining the security of premises against the leakage of language information by an optoelectronic channel is proposed, which includes technical, interior, technological and design solutions that will help ensure the protection of language information from laser acoustic intelligence systems. Detecting the penetration of laser radiation into the room is solved with the help of the following technical solutions: use of solar panels and lighting sensors, geometry of the arrangement of glass in window frames, application of special coatings. Detection of the influence of room elements on the probing beam is provided with the help of interior solutions: use of materials with a high attenuation coefficient and their location in the room, use of appropriate coloring and composition of absorbing surfaces. Detection of the effect of the masking ability of various glass types is achieved with the help of technological solutions: use of glass with different relief and scattering ability, use of relief protective films. Detection of the impact of room shielding is achieved with the help of design solutions: interior design, taking into account the size and location of windows and their soundproofing characteristics. The direction of further research is the study of the influence of external environmental factors on the acquisition of language information by laser acoustic intelligence systems.
