  • A blind audio watermarking algorithm with self-synchronization for copyright protection is proposed. In the application of media copyright management, the decoding results should have a time precision, better robustness and fidelity. However, most of algorithms can not provide enough robustness and time precision. To deal with these problems, in this paper, spread spectrum theory and the short-time relevance of audio signal are used to generate a watermark. To improve the fidelity of audio, a psychoacoustic auditory model is further used. Moreover, special synchronization strategy and watermark message frame structure are used to get a high time precision decoding results. Experimental results show that the watermarking scheme is robust against common audio editing attacks while keeping the watermarked audio a high perceptual quality.
