Huffman codes replacement algorithm is a new steganographic method by replacing Huffman codes to hide information. The advantages are simple computation, large capacity, good imperceptibility, and so on. However there is no steganalytic method can be used for the new algorithm. A statistical model of the Huffman codes replacement is presented by steganalysising a MP3 algorithm and a steganalysis scheme was proposed which was implemented by using support vector machine (SVM) to classify the stego audio from clear audio.
