用于图像认证的数字水印技术综述

Overview on digital watermarking for image authentication

随着网络技术和媒体信息数字化的飞速发展,用于图像认证的数字水印技术成为目前研究的热点。主要阐述了当前用于认证的数字图像水印技术的特征、认证系统框架,详细讨论了脆弱水印和半脆弱水印的算法和研究现状,并对认证数字水印技术的未来发展方向进行了展望。

With the development of Internet and digital of the multimedia information,image authentication based on digital watermarking is a hot research focus.This paper proposes the features of the fragile watermarking and the frame of the authentication system,then focuses on the algorithms and state of the fragile and semi-fragile watermarking based on authentication technology.Finally,the future development of digital watermarking for image authentication is also analyzed and conjectured in the paper.
