Feng Pan · Computer Engineering and Applications Journal · 2007
A new detection of steganography algorithm based on wavelet statistics of audio and multi-class SVM is proposed.In this algorithm,wavelet packet decompision is implemented to audio files,the magnitude of decomposition coefficients and the error between the actual coefficient and the predicted coefficient magnitudes are used to yield statistics.The multi-class support vector machine algorithm has been employed in the pattern discrimination.Stego audios created by several tools are tested under different embed rates.The experimental results show that the algorithm has stronger universal performance and higher discriminating rate.
