Self-Synchronization Property Audio Watermarking Anti-Synchronization Attacks

For the problem of digital audio watermarking against synchronization attacks, we propose a self-synchronization properties anti-synchronization attacks audio watermarking algorithm. The algorithm accorded maximize the autocorrelation of watermark data generated by the same pseudo-random sequence to get synchronization, using search mechanism of segments synchronization to obtain synchronization point of watermark without additional synchronization signal. So it make watermark more security. Theoretical analysis and experimental results show that the proposing audio watermarking algorithms is robustness to common audio signal manipulation, such as synchronization attacks, noise addition, filtering, sampling, quantization.
