Abstract
1. Способ стеганографической передачи информации, заключающийся в том, что данные скрывают в контейнере, роль которого выполняет канал передачи информации в телекоммуникационных или мультимедийных системах, использующих помехоустойчивое кодирование, отличающийся тем, что в цифровые данные, прошедшие помехоустойчивый кодер, вносятся предыскажения, зависящие от значений встраиваемых данных, текущего соотношения сигнал/шум в физическом канале и маскирующей функции, в качестве которой выступает генератор псевдослучайной последовательности, далее на приеме предыскаженные данные, прошедшие через физическую среду, подают на помехоустойчивый декодер, что позволяет, зная отсчеты до помехоустойчивого декодера, после помехоустойчивого декодера и функцию распределения скрытого канала, в основном, восстановить передаваемые стеганографические данные.2. Способ по п. 1, отличающийся тем, что скрываемые данные на передающей стороне дополнительно кодируют помехоустойчивым кодером, а на приемной, после восстановления, декодируют помехоустойчивым декодером.1. The method of steganographic transmission of information, which consists in the fact that the data is hidden in a container, the role of which is played by the data transmission channel in telecommunication or multimedia systems using noise-resistant coding, characterized in that predistortions are made in the digital data that have passed the noise-resistant encoder, depending on values of the embedded data, the current signal-to-noise ratio in the physical channel and the masking function, which is a pseudo-random sequence generator Then, at the reception, the pre-emphasized data that passed through the physical medium is fed to a noise-free decoder, which allows, knowing the samples to the noise-free decoder, after the noise-free decoder and the distribution function of the hidden channel, basically, to restore the transmitted steganographic data. 2. The method according to claim 1, characterized in that the hidden data on the transmitting side is additionally encoded by an error-correcting encoder, and on the receiving side, after restoration, is decoded by an error-correcting decoder.
