A BliND AUDIO STEGANALYSIS BASED ON FEATURE FUSION

Journal of Electronics(China) 2011年第3期28卷 265-276页

In this paper, we present a blind steganalysis based on feature fusion. Features based on Short Time Fourier Transform (STFT), which consists of second-order derivative spectrum features of audio and Mel-frequency cepstrum coefficients, audio quality metrics and features on linear prediction residue are extracted separately. Then feature fusion is conducted. The performance of the proposed steganalysis is evaluated against 4 steganographic schemes: Direct Sequence Spread Spectrum (DSSS), Quantization Index Modulation (QIM), ECHO embedding (ECHO), and Least Significant Bit em-bedding (LSB). Experiment results show that the classifying performance of the proposed detector is much superior to the previous work. Even more exciting is that the proposed methodology could detect the four steganography, with 85%+ classification accuracy achieved in all the detections, which makes the proposed steganalysis methodology capable of being regarded as a blind steganalysis, and especially useful when the steganalyzer are without the knowledge of the steganographic scheme employed in data embedding.

提出了一种新的MIDI隐写算法.该算法减小了在嵌入秘密信息时对原始数据的修改量,减小了隐写对原始数据统计特征的改变,增强了抗隐写分析的能力;在MIDI事件的时间和力度参数中同时嵌入秘密信息,并采用了自适应方法决定每个参数可供秘密信息嵌入的比特位置.实验结果表明,该算法对音质的影响几乎可以忽略;实现了较强的抗隐写分析能力;与传统MIDI隐写算法相比,隐写容量也有了明显提高.
