摘要: 目前国内外网页信息隐藏算法大多侧重于研究如何提高隐藏效率和扩充隐藏容量,而忽视了信息隐藏算法的安全性。为此,提出了一种基于不可见字符的主副式网页信息隐藏(PSWIH)算法,即以ASCII编码下的不可见字符为主方式实现信息隐藏,并以改变标签大小写、嵌入与待隐藏信息不相关的不可见字符、改变标签属性对顺序为副方式实现信息检测干扰。实验结果表明,相对于基于标签大小写、基于属性对顺序、基于不可见字符方法,PSWIH算法具有更好的不可感知性、抗提取性及鲁棒性。

Abstract: Current domestic and overseas webpage information hiding algorithms mainly focus on how to improve the hiding efficiency and expand the hidden capacity,but they neglect the security of information hiding algorithm.For this reason,the paper put forward a primary and secondary webpage information hiding algorithm based on invisible characters,in which information hiding is realized by the invisible characters based on ASCII coding as the primary method,and interference of information detection is realized by changing the letters of tag,embedding invisible characters unrelated to hidden information,changing the sequence of tag attributes as the secondary method.The experimental result shows that PSWIH algorithm is better than the method based on changing the letters of tag,changing the sequence of tag attributes,embedding invisible characters in non-perceptibility,extractability and robustness.
