The article deals with the study of modern steganographic methods and tools for processing digital images using software tools that are freely available through the Internet and available to the ordinary citizen. During the study, was performed identify the structural changes in graphics files which are the results, as well as, the result's images and the original's images. Was performed such comparisons: changes the size of graphics files; counting the number of modified pixel values of the images; study of the modification of the color image components and their respective bit planes; comparison of the structure of the received files. On the basis of the conducted researches were the results of relatively modern implementation methods hide information by steganography software that can be used in the future to improve the efficiency of steganographic system or steganographic analysis.
The article deals with the definition of the possibilities of using steganographic methods, namely, methods of information hiding and steganography analysis, in problems of protection of state information resources. During the work was identified the opportunity of the application of steganographic techniques to meet the requirements of protection’s services of information in information telecommunication systems where information is processed, with the aim of the implementation of protection’s systems in the integrated systems of information protection or protection mechanisms in the software or technical means of information protection. It was the research of the implementation of the steganographic methods of information hiding and steganographic analysis, their characteristics and applications. Based on the conducted research identified services of the information security, implementation of which can be used steganography techniques information hiding and steganographic analysis.
The article proposes and describes a method of identifying secure communication channels which have been formed with the use of a steganographic system on the basis of methods of the steganographic analysis. This method is based on identification hidden message built in the digital image using modifications of the least significant bit of the color component of the RGB model by comparing the distribution of the number of 1 bits in the conditional blocks of bit planes of the color components of the digital image and the character codes of text message when they submitted in binary representation. Listed the results of the research described method to detect and validate the presence of a hidden text message in digital image using the formed matrixes of conditional blocks of the color components; and also a priori language identification used in the hidden text message.
In the article has carried out a research methods to improve the stability of steganographic container up to at-tacks in the time of its transmission of the channels of communication. The main features fixed container was defined, namely a raster image. The analysis of the most common color models images was carried out. A method of rounding meanings elements image for modification low bit was offered. Put the results of the research to justify for the choice of a color model image with increasing stability of steganographic systems.
