Formation of the channel of leakage of speech information on apparently light

The paper provides an analysis of the acoustic leakage channel by means of modulating the visible light produced by solid-state lighting devices. The physical realizability of the considered channel of voice information leakage is shown; for this purpose, the authors use the Li-Fi technology. The analysis of the threat model of leakage of voice information on the channel in question is conducted. Analysis of the existing classification of acoustic leakage channels of information allowed us to propose the definition of the leakage channel in question.
