Abstract
In this paper, we present a semi-fragile audio watermarking technique which embeds watermark in the discrete wavelet domain of an audio by quantizing the selected coefficients. The quantization parameter used in the algorithm is user-defined. Different value of the quantization parameter affects the robustness of the watermark. This allows the user to control the performance of the watermark. The application of our approach could be copyright verification or content authentication.
