METHOD OF INFORMATION STEGANOGRAPHIC TRANSMISSION Russian patent published in 2017 - IPC H04L9/00 H03M13/00 

FIELD: radio engineering, communication.

SUBSTANCE: method is proposed in which the data is hidden in a container, the role of which is performed by the information transfer channel, the main and hidden channel data are fed to the noise-proof encoders, predictors are made to the digital data of the main channel, which are hidden channel data and dependent on the values of the embedded data, The current signal-to-noise ratio, the masking function and the time, on the receiver side from the output of the noise-proof decoder, the corrected data of the main channel is newly coded with an anti- A coder similar to the transmitting side and supplied to the hidden channel recovery unit, which is also fed with data from the demodulator output and passed the delay line, the reconstructed hidden channel data passes through the noise-immune decoder of the hidden channel, the corrected data is sent to the receiver of the hidden channel, which allows, having data streams from the noise-proof encoder on the receiving side, from the delay line, and also knowing the parameters of the hidden channel distribution function to basically restore the transmitted steganographic data.

EFFECT: providing secret information transfer with variable speed and specified reliability.
