  • A DWT domain multiple watermarking scheme based on blind source separation is proposed in this paper. In consideration of the embedding order and safety, two original watermarks are mixed with a chaotic sequence to generate an embedding watermark signal. Then the host audio signal is transformed into wavelet domain to obtain the low frequency coefficients and the embedding watermark is embedded in with the linear mixing model. In the extraction procedure, the FastICA is applied to obtain the embedding watermark signal and the original watermark signals. The scheme is a blind watermarking method and need not consider the embedding order. The experimental results show that the method proposed in this paper is robust against most common signal processing and the time-scale modification.
