摘要

Based on the researches of LSB (least significant bit, i.e. the last bit of a binary pixel value) matching steganographic method and the steganalytic method which aims at histograms of cover images, this paper proposes a new LSB matching steganographic method. A steganographic information table is defined to record the changes which are introduced by the embedded secrete bits. According to the table, the next LSB which has the same pixel value will be judged to add or subtract one dynamically in order to ensure the histogram’s change of cover image is minimized. Therefore, the modified method improves steganographic security and is less vulnerability to attacks compared with LSB matching. The experimental results show that the histograms maintain their attributes, such as peak values and alternative trends, in an acceptable degree and have better performance than LSB matching in the respects of histogram distortion and resistance against existing steganalysis.
