在这篇文章中，我们提出了一个方案，用于检测隐藏的消息在压缩的音频文件产生的MP3 Stego，我们的文献搜索没有发现以前的工作成功的隐写分析MP3 Stego。我们提取矩统计特征的二阶导数，以及马尔可夫转移功能和相邻的联合密度的MDCT系数的基础上，每个特定的频带上的MPEG-1音频层3。一个支持向量机被应用到不同的特征集进行分类。实验结果表明，该方法能够成功地区分MP3封面和由MP3 Stego生成的隐写图。
In this article, we propose a scheme for detecting hidden messages in compressed audio files produced by MP3Stego, as our literature search has found no previous work on successful steganalysis of MP3Stego. We extract moment statistical features on the second derivatives, as well as Markov transition features and neighboring joint density of the MDCT coefficients based on each specific frequency band on MPEG-1 Audio Layer 3. A support vector machine is applied to different feature sets for classification. Experimental results show that our approach is successful to discriminate MP3 covers and the steganograms generated by using MP3Stego.
