An algorithm for extracting invisible information from scanned polygraphic products

Abstract


We propose a steganalysis technique for the Invisible Personal Information algorithm intended for embedding digital watermarks (DWM) in polygraphic products and considered steganographically robust. The steganalysis technique in question involves two stages: first, out of the entire set of embedding keys a probable key subset is extracted and, then, the image is being prepared using each of the keys chosen so that a watermark can be discovered. Also, we investigate the robustness of the steganalysis algorithm relative to distortions due to printing and scanning of stegagrams with DWMs.
