摘要
XML文档越来越多地被用于数据交换,其安全性也变得越来越重要。可通过创建结构不同但拥有相同数据或者语意值的XML文档。可通过改变一些元素、属性顺序、增加或去掉一些不重要的空白来改变XML文档的结构,但是在逻辑上没有改变XML文档所拥有的数据或者表示的语意值。基于此提出一种新的XML文档数字水印算法,通过改变XML文档的结构,实现嵌入水印信息,以达到保护版权的目的。实验证明,该算法具有较大的水印容量,较好的隐藏性和鲁棒性。
There are more and more XML files used in data exchange,its security also becomes more and more important.One can establish XML document with different structure and same data or semanteme value.Through changing the order elements and attributes,adding or deleting some inconspicuous spaces,people can change the structure of XML document,but don＇t change the XML document data or semanteme of value on logic.Based on this,this paper proposes a novel XML document digital watermarking algorithm to embed a watermark into a XML document by changing the structure of it in order to achieve the goal of protecting the copyright.The experiment proves that this algorithm has the larger capacity of watermarking,better hiding and robustness.
