Bekirov A. Method of special information security increasing in critical systems based on structural steganographic coding

The thesis shows the solution of scientific and applied task, which includes improvement of special information resources security in infocommunication systems. In this connection, the option for this aspect of information security is a direction based on the using technology of steganographic embedding information into an image-container. In the process of research the following basic scientific and applied results were received: based approaches for improving the methods of direct embedding, developed a method of steganographic structural encoding with localization of structural steganographic redundancy, built structural steganographic system with steganographic masking redundancy, designed software implementation to assess the efficiency of the developed steganographic system. Implementation of steganographic embedding of specific information on the basis of this method can improve the security of special information resources in open infocommunication systems.
