Abstract

Internet wide spreads in our daily life, copyright protection of audio frequency becomes to a hotspot. In this paper, a novel algorithm for digital audio watermarking based on the discrete wavelet transform is proposed. In the condition of quantization, the watermark was embedded and extracted based on the contextual border upon low-frequency coefficients which was sorted. The experimental results show that this algorithm has good imperceptibility and robustness against common attack, and the watermark can be extracted without original data.
