  • Abstract
    A synchronous audio watermarking algorithm based on chaotic encryption in DCT domain is presented in the paper, which uses the synchronic signal to locate the watermark. The watermark and the synchronic signal are embedded into the low frequency components by quantization. Experiment results show that the proposed watermarking scheme is imperceptible and robust against various signal processing, such as low-pass filtering, adding noise, requantization and cutting.
