摘　　要：在计算机网络技术空前发展的今天,网络信息安全问题逐渐为人们所重视,由此激发了数字水印技术的快速发展,因此,数字水印技术的研究显得尤为重要。首先阐述了数字水印技术的研究背景及动态,并着重介绍了该技术的发展概况、分类属性、应用领域及抗几何攻击性能。给出了该技术的理论框架,并通过分析图像水印技术的不可感知性和鲁棒性,详细阐述了其抗几何攻击方面的水印算法和相关技术。With the development of computer network technology,network information security problems became more and more important, which has promoted the rapid development of digital watermarking technology. Therefore, the research of digital watermarking technology is particularly important. This paper describes the background and dynamic digital watermarking technology,and emphatically introduces the general development of the technology,the classification properties,the application field and the performance against geometric attacks. At the same time,the theoretical framework of the technology is given and its resistance to geometric attacks and related technology are described in detail by the analysis of image watermarking imperceptibility and robustness of the watermark algorithm.
