Variogram Analyses of Steganograms Shaped Following Integrated Methods of Data Hiding

The paper is devoted to analysis of effectiveness the applying of correlation and variogram analyses for steganogram detection. The case of usage multistage steganographic methods for data embedding in digital images is considered. Applying of variogram analysis gives opportunity to disclosure the steganograms even in case of low container’s degree of stegodata filling. It is shown that correlation analysis has limited opportunities in mentioned case.
