Essay

Thesis is devoted to protection issues of information by cryptography and steganography methods. New steganographic algorithm based on segmentation split/merge method has been suggested; which is robust to attacks of the passive intruder. The spectral algorithm of data hiding robust to attack of JPEG compression with losses has been upgraded. The technology of an effective use of steganoanalysis methods for different formats of graphic files has been elaborated. The cryptosteganographic systems model of data protection is offered. The experimental researches on containers-images which have confirmed theoretical results have been conducted.
