A content-based protection model for Chinese characters information

Abstract

In this paper, we consider the problem of the content-based Chinese information protections on the web. A new Chinese character security computing model is proposed in this study. The model consists of Chinese character dynamic description (CCDD), CCDD information protection method, and a CCDD information hidden method for Chinese character and Chinese electronic document which is accomplished by defining the stroke-element of Chinese character. The CCDD component is based on Chinese dynamic description technology, which provides a mapping table to extract the stroke-element from the strokes and realize embedding hidden information into Chinese character glyphs. A Chinese character dynamic description library (CCDDL) for the glyphs of Chinese characters is constructed in this model. A novel approach for storing the glyphs of Chinese characters on the web and outputting the characteristic glyphs on the client is fully implemented. Our experiments revealed that the proposed model is effective in Chinese information security and protection.
