A novel RS steganalysis algorithm based on support vector machines
Guangxi Chen · Journal of Guilin University of Electronic Technology · 2008
RS steganalysis method is a typical arithmetic in steganalysis theory used for testing steganography least significant bit,but its accuracy is not ideal in the case of the circumstance of low embedded rate.As a response to this problem,a steganalysis algorithm based on statistis theory and support vector machines is proposed in this paper.The revised arithmetic uses SVM to classify selected characteristic set on the condition that RS characteristic selected strategy is kept.The experiment shows that the revised arithmetic is superior to RS steganalysis algorithm in original raw losslessly stored images.
