浅议数字水印算法及性能评估

A Brief Discussion on Digital Watermarking Algorithm and Performance Evaluation

现阶段,人们足不出户就可以获取来自全球各地的所有信息,这些信息的来源主要是网络上的数字化资源。保证这些资源的版权和真伪一直是研究的热点。数字水印技术是进行版权保护最好的办法,本文阐述了数字水印的四类典型算法,介绍了数字水印攻击的类型,最后提出了评测数字水印系统优劣的指标。

At this stage,people can get all the information from all over the world without leaving home,and the source of these information is mainly based on the digital resources on the network. To guarantee the copyright and authenticity of these resources has always been the focus of research. The digital watermarking technology is undoubtedly the best way to solve this problem. This paper introduces the four types typical algorithms of digital watermarking and the type of the attack. Finally,it puts forward the index of evaluating the advantages and disadvantages of the digital watermarking algorithm.
