A Multi-Source Steganography for Stereo Audio
Yue Wu · Journal of Wuhan University · 2013
We proposed a steganography algorithm for stereo multi-source audio by studying sound source separation technique based on spatial clues and using it in information steganography technology.In this algorithm,the binary spectrum mask technology which is used in sound source separation technology is introduced in steganography algorithm.Regard the separated sound sources as carriers,and embed the stereo sound,by modifying part of the coefficients in odd windows in time-frequency domain,to achieve steganography information embedding,which replaces the traditional single source embedding steganography algorithms.Experimental results show that this algorithm has large embedding capacity,and it is able to resist the attacks of StriMark Benchmark for Audio and other common attacks effectively.The average bit error rate is smaller than 2.80%,which provides good robustness.
