A Model of a Digital Graphic Image Containing Steganographic Information

E. P. Stelmakh
A. V. Skurnovich

RÉSUMÉ

The use of wavelet transform for detection of changes introduced by steganographic programs into digital graphic images is analyzed. Requirements to a model of an image containing hidden information are proposed. A model of such image is suggested based on an analysis of the statistics of high-order coefficients of multiscale wavelet transform. Practical results of the use of the developed model are presented.
