摘要
图像认证是近几年发展起来的新技术,目前主要有2种用于图像认证的技术:基于数字签名的图像认证和基于数字水印的图像认证技术。主要针对基于数字水印的图像认证算法分类详细介绍了几种经典算法,对这几种算法各自的优缺点作出比较分析,最后对未来算法的研究工作做出了展望。
Image authentication is a new technology which has been developed in recent years. At present, digital signature and digital watermarking are the two main methods to solve the problem of image authentication. In this paper, the authors mainly study on several classic image authentication algorithms based on digital watermarking, comparing and analyzing their advantages and disadvantages. At last, the authors also make an outlook to the future work on authentication algorithm.
