摘要
在同一音频作品中先后加入稳健水印和脆弱水印,通过对小波变换系数模2取余方法嵌入稳健水印,通过对离散小波变换系数采取适当的量化处理嵌入脆弱水印。讨论了嵌入参数对水印不可知性、稳健性和脆弱性的影响。
The robust watermark is embedded into the digital audio product based on the modular arithmetic in DWT（Discrete Wavelet Transform） coefficient. The fragile watermark is also embedded into the same product by adopting proper quantization strategy in DWT coefficients. Influences of the embedding parameters on the watermarking performance which include imperceptibility, robustness and sensitivity are discussed.
