摘　　要：提出一种能在一幅图像中同时嵌入鲁棒性水印和易损性水印的复合算法,并对两种水印的嵌入提取策略和过程进行实现和实验验证.结果表明:该水印复合算法以降低较少的水印鲁棒性为代价,实现了对原始图像的双重保护功能.An algorithm of compound adaptive digital watermarking was presented, which can embed robust watermark and fragile watermark in one image simultaneously. Embedding draw tactics and course of watermark are realized and verified. The result of validate indicated that the embedding algorithm of compound watermark scarified less robust watermark as a cost, which achieved the dual-protection function for the primordial images.
