This article explores the steganographic techniques of hiding in- formation using direct spectrum expansion technology. Using noise-like pseu- dorandom sequences (discrete signals), it is possible to reliably hide in- formation messages in redundant digital data (cover files), for example, im- ages, video and audio files, etc. However, the correlation of discrete signals and cover files can be a problem; the extracted information messages can cover a lot of the number of errors. Our experiments (on still images) show that the error rate in the reconstructed information messages is very high. We offer a new technique when the statistical properties of covers are taken into account when generating discrete signals. In this case, it is possible to significantly reduce the error rate without introducing additional distortion in-to the cover.
