一种基于CSS属性符号标记的信息隐藏技术

An Information Hiding Technology Based on CSS Property Symbol Marking

网页作为信息传递的一种载体,其特殊性决定了信息可嵌入性,可以进行信息隐秘通信。基于此,分析网站构成的CSS代码,对其进行可嵌入信息分析,利用类渲染内容符号不敏感的特点,提出利用CSS符号标记的信息隐藏技术,以标记的形式嵌入CSS文件。信息隐藏技术是信息安全技术的一个分支。实验证明,此方法可以具有很好的安全性、鲁棒性,嵌入量也很高。

As a carrier of information transmission, the particularity of web pages determines the embeddedness of information and can communicate secretly. Based on this, this paper analyzed the CSS code of website, analyzed its embeddable information, and put forward the information hiding technology of using CSS symbol tags to embed CSS files in the form of tags, taking advantage of the insensitivity of class rendering content symbols. Information hiding technology is a branch of information security technology. Experiments show that this method has good security, robustness and high embedding capacity.
