摘　　要：随着计算机通信技术、多媒体信息处理技术以及互联网技术的快速发展,各式各样的多媒体信息通过网络传输的途径也越来越方便快捷,因此,如何在网络环境下保证传输多媒体信息的安全性已经成为一个亟待解决而且富有挑战性的问题。在这样的背景下,音频、视频、图片等信息的拷贝和仿制都变得轻而易举,防伪溯源技术的探究变得越来越重要。数字水印技术作为一种信息隐蔽技术,通过采取特殊算法将一些富有意义的标识信息嵌入图像中。其在图像加密过程中,兼顾了隐蔽性和明确性,保证了图像质量和安全性。基于此,笔者重点分析了基于数字水印的图像加密技术,希望能够为相关研究提供借鉴。With the rapid development of computer communication technology,multimedia information processing technology and Internet technology,a variety of multimedia information transmission through the network is becoming more and more convenient.Therefore,how to ensure the security of multimedia information transmission in the network environment has become an urgent and challenging problem.In this context,audio,video,pictures and other information copy and copy become easy,the anticounterfeiting traceability technology research has become more and more important.As a kind of information hiding technology,digital watermarking technology embeds some meaningful identification information into the image by adopting special algorithm.In the process of image encryption,both concealment and clarity are taken into account to ensure the image quality and security.Based on this,the author focuses on the analysis of image encryption technology based on digital watermarking,hoping to provide reference for related research.
