【摘要】 现有的网页信息隐藏算法存在信息隐藏点与网页内容分离、抗机器过滤能力较差的缺点.基于CSS类选择符重复引入策略,提出了一种新的网页信息隐藏算法.按照嵌入规则,采用重复引入可操作CSS块中相关对象的CSS类选择符的方法来嵌入信息.实验结果表明该算法信息隐藏点与网页内容紧密地结合,提高了抗检测和抵抗机器过滤的能力,且具有较好的隐蔽性,能够隐藏较大量的信息,可以应用于网页保护和隐秘通信.更多还原

【Abstract】 The traditional algorithms of webpage information hiding has the common shortcoming that their embedding location is separated from the content of the webpage,so the ability of contradiction with auto filtration is very poor.Based on the scheme of repeated importing the class selectors,a novel webpage information hiding algorithm is proposed in this paper.According to the embedded rule,the living class selectors of some objects in the operable block of CSS are caught and repeatedly imported to embed information.The experiment result shows that the algorithm has good ability to contradict with detection and auto filtration,has preferable imperceptibility and can embed a number of messages.It can be used to webpage protection and covert communication.更多还原
