Abstract

The invention discloses an information hiding and extracting method based on an HTML (Hypertext Markup Language) label attribute sequence. The method comprises the following steps: step 1, determining to-be-hidden information, and converting the to-be-hidden information into a binary Unicode; step 2, determining representing methods of '0' and '1' corresponding label attributes, wherein '0' is represented by two attributes of two different labels, and '1' is represented by two attributes of a same label; step 3, determining a sequence code K, wherein the Unicode consists of 8 binary numbers; selecting nine '1' (one more selected), randomly inserting a plurality of '0' among the nine '1' so as to form the current-time information hiding sequence code K; step 4, determining nine label attributes according to the sequence code K, sequentially putting the nine label attributes on the '1' positions, supplementing residual label attributes, sequentially putting the residual label attributes on the '0' positions so as to synthetize an HTML file label attribute sequence; and step 5, editing codes according to the HTML file label attribute sequence. The method has the beneficial effects that a database is not needed for support, and the webpage execution efficiency is greatly improved.

Description

Technical field [0001] The invention involves information hiding and extraction methods. More specifically, it involves a method of hiding and extraction methods based on the HTML tag attribute sequence. Background technique [0002] HTML (Hyper Text Markup Language, Super Text Marking Language) is developed with the Disclanguage.Because HTML can realize the links between the relevant text and data and the file between the file and the file.Compared with text, super text has richer multimedia content and effects; compared with other words processing files, the amount of information is relatively small, which is very important for online transmission of multimedia information.Because of these outstanding features, this format file is widely used on the website of the Internet and E-mail, and the corresponding information security issues also occur at the same time.Therefore, the research of HTML information hidden technology came into being. [0003] The HTML page is composed of a...
