摘要
伴随着计算机网络技术及多媒体信息技术的快速发展,为了更好地保护数字图像,用于图像认证的数字水印技术已成为当今研究的热点。主要阐述了当前用于图像认证的半脆弱水印技术研究现状及其攻击行为分析,并对几种典型的图像认证算法进行了介绍。通过对典型认证算法的研究,提出了认证数字水印技术未来的发展方向。
With the development of internet and digital of the muhimedia information, and aiming at protecting the digital image, digital watermarking used for image authentication has been a hot research focus. The image authentication's research status and analysis of aggressive behavior were proposed. Some typical image authentication algorithm was introduced. Finally, the future development of digital watermarking for image authentication was also analyzed and conjectured.
