摘要
数字水印技术是一项保护版权的信息隐藏技术.数字图像作为网络传播的主要媒体内容,数字水印技术对保证其在互联网传播过程中的安全性具有重要意义.通过归纳分析近年关于数字水印技术的研究成果,对数字水印技术分类、水印生成过程、水印嵌入类型以及水印评价标准等方面进行阐述,对部分典型水印算法进行总结,并结合当前信息安全和信息隐藏研究现状,展望数字水印技术未来发展前景.
Digital watermarking is an information hiding technology that protects copyright.Digital images are the main media content of network transmission.Digital watermarking has the great significance in ensuring the transmission security on the Internet.Through the inductive analysis of the research results of digital watermarking in recent years,the classification of digital watermarking,watermarking generation process,watermarking embedding types and watermarking evaluation criteria were explained.In addition,some typical watermarking algorithms were summarized,and combined with the current research status of information security and information hiding,and the future development prospects of digital watermarking was analyzed.
