为了更好的保护版权并保证隐藏通信,建立了嵌入同一个水印并通过不同的密钥来分别得到鲁棒水印和脆弱性水印的模型,基于此提出了采用双极性量化策略对离散小波高频系数总能量进行均匀量化的盲提取音频水印算法.新算法以水印的特征值作为水印预处理的密钥.仿真实验表明该方案具备较好的鲁棒性和脆弱性.

@@@@In order to protect the copyright and guarantee the hidden communication better ,the model which can get robust and fragile watermarks with the same embedded watermark through the different keys is established .And then the blind extracting audio discrete watermarking algorithm based on polarity quantification of uniform quantitative the high frequency of total wavelet energy is proposed .The new algorithm takes the characteristic value of the watermark as the key of watermark pretreatment . Experimental result shows that the project has better robustness and fragility .
