摘要

本文提出了一种半脆弱音频水印技术，通过对所选系数进行量化，在音频的离散小波域中嵌入水印。算法中使用的量化参数是用户自定义的。量化参数的取值不同会影响水印的鲁棒性。这允许用户控制水印的性能。我们的方法的应用可以是版权验证或内容验证。

A novel semi-fragile audio watermarking scheme

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.
