Abstract: Work is devoted the review of statistical steganoanaliz methods of digital images, that created on the basis of estimation of centre-of-mass of discrete Fourier transformation of image histograms. Theoretical bases for creation of technology of the examined methods are developed in supposition about additive hiding of additional information. Effect of additive distortion on signal statistics was analyzed for the hiding norm α ≤ 100%. Embedded information detectors are considered that requiring selection procedure of detection threshold and that using the histogram of a hypothetical smoothed image.
Keywords: steganalysis, the histogram of a hypothetical smoothed image, additive embedding
