摘　　要：提出了一种基于小波变换的盲水印算法,根据各个层次相应位置的小波系数排序情况和密钥中{1}元素的位置来决定水印嵌入的位置,在水印提取时根据密钥中{1}的位置可以实现盲水印提取,实验证明具有较好的效果。This paper presented a kind of blind watermarking algorithm based on wavelet transform. The watermark series was embedded depending on every level wavelet coefficients of corresponding locations and the locations of {1} in the secret key. The watermark could be extracted according to the locations of {1} in the secret key, and that was blind watermarking extracting. This method was proved to have a good robust character by experiments.
