An Algorithm of Webpage Information Hiding Based on Class Selectors

The traditional algorithms of webpage information hiding have the common shortcoming that their embedding location is separated from the content of the webpage, so the ability of contradict with auto filtration is very poor. Based on the specification of cascading style sheets, brief in CSS, 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 could embed a number of messages. It could be used to webpage protection and covert communication.
