Abstract :
The offered algorithm stability to illegal decoding fully corresponds to RSA algorithm stability. Nevetherless, according to practical utilization of described RSA modification, in the coded image we managed to achieve complete noising and avoid domains of similarity (Fig. 5). At the same time to display outlines of the sent image becomes practically impossible. It gave possibility to level possibilities of traditional means usage of image working for illegal receiving of info from the coded image.
