摘要
A new audio information hiding algorithm based Singular Value Decomposition (SVD) is presented. We used discrete wavelet transform (DWT) to obtain the low frequency sub-audio of the host audio. The secret message is embedded in low frequency sub-audio by SVD. Logistic chaotic was utilized as chaotic sequence to process the secure image, the algorithm achieved blind extracting. Many experimental results indicate that this algorithm not only has good imperceptibility, but also has strongly robust to many attacks, such as various noises, re-quantitative, re-sampling, and cutting attack.
