Bisynchronous Approach for Robust Audio Watermarking Technology

A kind of bisynchronous approach, including two processes of selfsynchronization and additive synchronization, is proposed for audio watermarking to get the robust performance. The self-synchronous valley is created for watermark location rapidly, and the additive synchronous approach is adopted to locate the usable watermarks. Moreover, an adaptive matching approach is stated to obtain the final watermark from several candidates. The experimental results show that the valleys can be searched rapidly and effectively. The approach is robust against most common attacks.
