Abstract: The current audio watermarking algorisms lack effective techniques for synchronization.In this paper,the synchronization scheme in communication network is adopted and a fast resynchronized meaning-ful audio watermarking algorithm is proposed.These are some characteristic:with the technology of spatial watermarking,synchronization signal is embedded into the audio signal in order to resist some possible attack along the time axis;the algorithm which is based on the use of wavelet transform domain can enhance the robustness,and the watermark is a binary image here.The experiment results of the emulation show that the algorithm has good robustness in the watermark confrontation additive Gaussian noise,MP3 compression and cutting,and other aspects,and it can be used for digital audio products copyright protection.
