摘要:

提出一种基于Huffman码表分布特征和重编码的MP3Stego隐写分析方法.该方法通过Huffman码表分布特征有效地反映了MP3Stego隐写造成的块间量化不均现象.利用重编码得到校准的载体音频,减少不同载体造成的差异,从而提高检测率.实验证明,该方法对MP3Stego有很好的检测效果,在极低的嵌入率下效果仍稳定.

Abstract:

We propose a new steganalysis approach against MP3Stego based on Huffman table distribution and recoding scheme. Huffman table distribution features are used to detect uneven quantization among blocks. Recoding scheme can be used to calibrate cover signals and to reduce the variety caused by different carriers. Experiments show that our method is successful in detecting MP3Stego even at a very low embedding rate.

Key words: information hiding, steganalysis, MP3, MP3Stego
