中文摘要：

为了解决数字水印的鲁棒性及个性化设计的问题,将计算机产生的罗曼编码全息图作为水印图像嵌入到原始图像之中.由于计算机产生的全息图不需要实际物体的存在,故水印设计者可以根据自己的想象制作出各种个性化的水印.此外,不可撕毁性是全息图特有的重要属性,因此用其作为水印图像应具有较好的鲁棒性.最后,各种模拟攻击测试实验表明该方法切实可行、鲁棒性较好.

英文摘要：

In order to solve the problem of robustness and individualized design of digital watermarking,computer generated hologram based on Lohmann coding is used as watermarking image to be embeded into the original image.Because computer generated hologram doesn＇t need physically existing objects,designers can design all kinds of individuclized watermarking images.In addition,the hologram has a lot of redundant information,so it can＇t be destroyed and has better robustuess as watermarking image.Various attack experiments show that the algorithm is feasible and robust.
