Abstract Based on the audio amplitude distribution change caused by secret message embedding in different bit-planes, a method of secret message length estimation is presented in this paper. This method can not only discriminate the existence of secret message, but also recognize the embedding bit-plane and estimate the amount of secret message. The proposed method has been implemented on PC. The experimental result shows its good recognition performance and relatively high estimation accuracy of secret message length. The proposed method can be used effectively in audio steganalysis.
