中文摘要：
提出一种基于带参数整数小波变换和相对小波系数模糊关系的数字水印算法。应用基于视觉系统小波城量化噪声的视觉权重分析方法，自适应的构造模糊关系矩阵，在水印的提取过程中实现了盲检测。本方法与经典的密码理论以及高级加密算法相结合。应用Rabin方法生成单向Hash函数，信息隐藏算法可以完全公开。水印算法不可感知性好，鲁棒性强，是一种有效的版权保护方法。
英文摘要：
In this paper, a water marking arithmetic is proposed which is based on te wavelets with parameter and wavelets coefficient fuzzy relation. The matrix of fuzzy relation is image-adaptive according to the wavelet quantization noise, with the maximum strength of Just Noticeable Distortion tolerance of Human Visual System. And this watermarking is a kind of blind watermarking. The watermarking combines with classical cryptology arithmetic. And we construct Hash one-way by the Rabin method, and the arithmetic can be public. The watermarking is non perceptible and safety, so it is effective method to protect information.
