METHOD AND APPARATUS FOR ACTIVELY PROTECTING CONFIDENTIAL VOICE INFORMATION FROM LEAKING OVER ACOUSTO-OPTIC FIBRE CHANNEL BY USING EXTERNAL OPTICAL NOISE MASKING Russian patent published in 2011 - IPC H04K3/00

Abstract RU 2416167 C2

FIELD: information technology.

SUBSTANCE: external artificial optical noise at acoustic frequencies is entered into the optical cable of standard information transmission systems. The apparatus for implementing the active protection method has a light source with a fibre optic output that generates optical radiation with a noise spectrum at acoustic frequencies.

EFFECT: eliminating leakage of voice information.
