Essay

The dissertation is devoted to the questions of information security with the methods of digital steganography. New effective spectrum steganographical algorithms based on Fourier theory and truncation errors theory have been proposed. The algorithms can be used as the base for construction of stable steganographic systems with the high rate communication canal created and protected with them. Also they can be an additional level of protection in any well known systems of encryption. Proposed algorithms were grounded and their main characteristics were analyzed. The algorithms were optimized by calculative speed. The experimental researches have been made on the model and real data with the developed software. The re-searches confirmed theoretical results.
