摘要：MP3Stego is a typical steganographic tool for MP3 audio, which embeds secret message into MP3 audio according to the parity of the block length. In this work, we present a steganalytic method to attack MP3Stego. The big_values inside information is considered to extract the steganalytic feature. Re-compression calibration has been applied in order to improve the feature's sensitivity. Experimental results show that the extracted feature can reflect the MP3Stego trace effectively.
