Abstract


Information hiding technology, famous for its nature of "hidden secret communication existence" is a way to protect information safety. Because the web is an important carrier of dissemination of information, people pay more and more attention to the protection of its content. Because of that, web program security has become the hottest issue in the web technology application.This paper is mainly aimed at dealing with the HTML code. Web program is a kind of proposed information hiding method that is based on invisible characters and the irrelevant changes of letters case. This method has a larger hidden information capacity and better concealment. This paper did some research based on the HTML tags web information hiding technology, of which the main work is as follows:(1)This paper presents the first systematical summarization of the information hiding, text information hiding and web information hiding in three aspects: concept, theory and model. An objective analysis of the current characteristics of the methods available and their respective advantages and disadvantages is also included.(2)Aiming at solving the existing problems concerning the HTML tags,we’ve studied the characteristics of properties and property values, thus summarized some feasible methods based on HTML tags and format that could be used for the information hiding after carrying out a lot of experiments by employing the page display effect,.(3)The paper proposes some information hiding methods according to the current ones based on web tags. By this method, we may hide the information by changing tags and models in the web .The method is information hidden based on having no relation with the change of the invisible letters and CAPS. As a result, it improves the current one which has no relation with the change of the invisible letter and CAPS. The method provided in this essay hides the information mainly by adding space in suitable places and modifying tags or property CAPS. So, it doesn’t affect the web show. Aiming at the specific method, this article proposes the details of the rules of inserting and picking-up of the hidden information. It,also supplies the framework for the realizing program with some vivid application examples.
