摘　　要：提出一种基于离散小波变换的盲检测数字水印算法.该算法在嵌入时,采用同一水印多重嵌入的思路,不但实现了盲提取,同时还提供提取水印时所需要的纠错信息,提高检测的正确率.通过实验证明,该算法具有较理想的安全性、鲁棒性,且由于该算法在提取水印时不需要原始信息,因此将水印技术应用于产品的网络发布和传播时具有一定的优势.A new digital watermarking algorithm with blind test based on dispersed wavelet transformation was proposed, in which identical watermarking repetitious embedding idea was used. The algorithm not only realized blind extraction, but also provided rectifying information to enhance the exactness rate for watermarking detection. The experimental result showed that the proposed algorithm was secure and robust. At the same time, the algorithm did not need original information to extract the watermark. Without doubt it was superior in the application of watermark technology to network issue and dissemination.
