摘要
本文通过研究图形学中图与图之间的关系以及人们对汉字认知习惯的特点,将汉字拆分为多个汉字组件。将每个汉字组件看作一个图形单位,对照图与图之间的关系,将这些汉字组件进行重新的组合,从而使同一个汉字具备了多个字形。通过使用不同的字形,将水印信息嵌入到文本当中。实验证明,在水印的不可感知性、鲁邦性等方面均获得了很好的效果。
Based on studying of the relationship between multi-graphs and the human cognitive habits of the Chinese characters,and split one character into a number of components,then Each component as a graphic unit,and according as the relationship of multi-graphs,recombine these components using different way,which makes one Chinese character has multi font style.Through using different font style,embed the water mark into the text.Compared with the previous watermarking algorithm,this algorithm gets a big step forward on aspect of invisible character and robust character.
