今天已经进入了数字化的时代，信息技术这门领域突飞猛进的发展，所以人们给予了信息安全更高的关注。研究信息安全学者们把目光投向了信息隐藏学科。信息隐藏将秘密信息嵌入到载体中并保证与原始载体有着最小的差异再进行传输。在这历史性的转折点上，数字水印就横空出世了。该论文应用混沌随机数生成水印模板，具有很好的随机性和不可追踪性，在利用小波分析的技术，将水印嵌入到载体中，处理效果更好。该文经过仿真实验的测试，通过多次的测试分析，得到的本水印系统首先在水印的不可见性和鲁棒性之间能达到一个很好的平衡。其次通过仿真攻击结果可以看出，该水印系统对一般的旋转、压缩、剪切、加噪声和滤波等，都有一定的抵抗性，并且还对马赛克攻击和模糊攻击有一定的抵抗性。

Nowadays , today in the development of digital information technology rapid development , people give more atten-tion to information security . The discipline of information hiding has become the focus of information security . And the infor-mation hiding that let the secret information into the carrier ensuring that has the smallest difference with the original carrier . So in this case, the digital watermark technology was born. This paper what to produce random sequence use the Logistic chaotic and than to make the watermark. Than it’s time to embed secret information of wavelet domain image to correspond wavelet in-verse transform. The invisibility and robustness reach a good balance about this watermark system. Through the simulation experi-ment results can be seen the watermark system has a certain amount of resistance for the general, rotation, compression, shear, add noise and filtering and so on. The watermark system also has a certain resistance for the fuzzy attack and the Mosaic attack.
