Abstract:

To solve the constraint relationships between robustness and imperceptibility of the DWT-DCT-SVD based audio watermarking, a watermarking scheme based on heuristic search is proposed in this paper. Relations among embedding strength, imperceptibility and robustness are analyzed. An embedding strength optimization model is constructed according to these relations, and a heuristic search algorithm proposed to obtain the solution. Comparative experiments show that the proposed solution has good imperceptibility, and can resist various signal processing and StirMark attacks.

Key words: singular value decomposition (SVD), heuristic search, audio watermarking, embedding strength
