Information support of steganography messages hiding

Abstract

Hiding information with steganography means an actual and complicated task from the point of view of modern achievements and data transfer possibilities. So, modeling of information processes of messages hiding with steganography is a necessary, continuously developing and improving process. This work is a review of theoretical implementation of two methods of information model functioning process. Methods of implementation of transformation of input and output data, used in steganography systems, together with their text description were researched in this work. Use of such description enables implementation of semantic analysis of input and output data transformations which itself enables evaluation of adequacy between the aim of the task and received result. A lot of aspects of the aim of steganography transformations are described as a text, so the methods, reviews in the work, are specialized on work with text fragments.
