The considered channel of information leakage potentially represents a probable risk of information leakage. The formation of a leak channel is associated with the use of lighting devices. The calculated estimated values of the leak channel channel indicate its high potential danger. The considered model of the leakage channel of acoustic information by means of modulation of visible light based on digital modulation methods makes it possible to use a maximum likelihood receiver to receive a coded signal susceptible to intersymbol interference and additive white Gaussian noise.
