IDENTIFY COVERT CHANNELS TRANSFER INFORMATION ON THE BASIS OF STEGANOANALYSIS

Abstract

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.
