为了解决网页可能被篡改的问题，提出了两个基于信息隐藏的网页认证协议，分析并比较了两个协议的特点。然后提出了一种利用GIF图像的调色板来隐藏网页的数字签名的方法，实现了极佳的透明性和较大的嵌入容量。理论分析和实验结果表明，提出的协议和算法可用于保护现有的网站和网页系统。

In order to protect the integrity of web page content, two authentication protocols are proposed based on information hiding technique. The properties of two protocols are analyzed and compared. A method is also proposed to hide a web page's digital signature into the GIF image's palette. The method achieves perfect transparency and high embedding capacity. Theo-retical analysis and experiments demonstrate that the proposed protocols and the algorithm can protect the current websites and web pages for practical purpose.
