Abstract

This paper analyzes the properties of the audio information-hiding tool -- MP3Stego, and proposes a new detecting method. This method can detect mp3 files produced by MP3Stego correctly by calculating the statistics of part23 length and stuffingBits in mp3 files, and can estimate the size of embedded text accurately by calculating the variance sequence of the block length. The experiments prove that this method is effective.
