A fast and effective method to detect multiple least significant bits steganography
Xiaoyi Yu, Noboru Babaguchi · 2008
In this paper, we propose a fast and effective LSB steganalysis for detecting the existence of hidden message and estimating hidden message length when the embedding is performed using both of two distinct embedding paradigms in one or more than one LSB. The method is based on the analysis of image statistics and quadratic equation. Compared with weighted stego-image based method, Ker's method and Luo et.al.'s method, the detection accuracy is high. Experimental results and theoretical verification show that the proposed method is an effective method of LSB steganalysis.
