Imperceptibility, robustness and security are the vital considerations in the design of any audio watermarking scheme for copyrights protection. In this paper, a secure and robust audio watermarking scheme involving multiple scrambling and adaptive synchronization is proposed. To prevent the unauthorized detection, the new scheme integrates multiple scrambling operations into the embedding process. That is, encrypting the watermark with a coded-image and randomly selecting certain subbands for the embedding process. Moreover, the detection utilizes adaptive synchronization to enhance the robustness under some destructive de-synchronization attacks, like random samples cropping/inserting, pitch-invariant time stretching, and tempo-preserved pitch shifting. Theoretical analysis and simulation results have revealed that the proposed scheme is self-secured indeed and also immune to a wide range of severe attacks.
