摘　　要：数字水印技术是近几年发展起来的新技术,根据其应用一般可分为:用于版权信息保护的鲁棒水印(Robust Watermarking)和用于篡改检测的认证水印(Authentication Watermarking)。本文详细介绍了基于数字水印的图像认证技术的特点、分类和研究现状,分析各种算法的优缺点,并提出下一步对认证水印技术的研究方向。Digital watermarking is a newly developed technology in the recent a few years. There are two types of it according to the functions： one is Robust Watermarking which is used in copyright information protection, and the other is Authentication Watermarking which is used in tamper proofing. This papers is to introduce in detail the features, classification,and the current study of image authentication based on digital watermarking, analyzing the pros and cons of various calculation, so as to put forward the further study orientation of digital watermarking image authentication.
