易损数字水印技术:研究与应用 %A 陆唯杰 %A 陈克非 %J 计算机科学 %D 2002 %I %X Recently, digital watermarking techniques for multimedia get fast growth. Digital watermark is some in-formation that will bring no perceptual feeling when embedded in the multimedia data. There are mainly two kind ofwatermark: robust watermark for copyright protection and fragile watermark for data integrity and data authentici-ty. In this paper, we will mainly focus on fragile watermarking. For the purpose of multimedia integrity and authen-ticity protection, we classify current methods into three categories: digital signature techniques, fragile watermarkingtechniques based on Hash function and other fragile digital watermarking techniques. And we discuss each category inthis paper, and especially discuss fragile watermarking in detail. Such a classification will help us understand thefunctions of digital signature and fragile watermarking in data integrity and authenticity protection. And we also dis-cuss some attacks on fragile watermarking and its applications. %K Fragile watermark %K Digital watermark %K Alteration detection
