Method of verification of authenticity of information that is passed by steganographic communication channel

Abstract

The improvement of steganographic method which was developed earlier by the author, which has no analogues among modern steganomethods, as it solves simultaneously a triple task: secret data (additional information), as a random binary sequence — authentication and check the integrity of additional information. As a container it views digital color images. It shows the results of numerical experiments that confirm the high efficiency improved steganometod in identifying inauthentic of additional information.
