Description: Approach for increase of information security on the basis of digital steganography methods using is offered in this article. The shortcomings analysis of existing direct embedding information methods in the image container is carried out. For visual stability increasing of existing methods of embedding the functionality from number with embedded information is entered. Requirements for the functional conversion of number with embedded information are formulated. For compliance to requirements of visual stability steganonumber, resistance to transformation and attacks approach for the functional conversion on the basis of nonequilibrium positional coding is reasonable.
Keywords: digital steganography, visual stability, steganogram, algorithms of embedding, nonequilibrium positional number, nonequilibrium positional coding
