摘　　要：利用网页来隐秘传递信息,具有重要的研究意义和实用性.提出了双比特的隐藏方法,使网页表格的隐藏容量比已有方法增大了一倍.同时,针对网页存在多个表格结构的特点,对平行表和嵌套表的进出特性进行分析,设计了全面的多表格隐藏算法和进出管理方法,详细分析其变化路线.本算法可以用于各种规则的多表结构和单表结构,多表结构适于任意平行表和嵌套表的组合.实验结果表明,基于表格属性的网页隐藏方法,具有很好的实用性、隐蔽性和透明性.It is very important and practical to transform messages securely through the web pages.A kind of two-bit hiding approach is proposed to double the hiding capacity of webpage table than the existing method.Meanwhile,considering the status of multiple table structure in a webpage,the features of parallel tables and embedding tables are analyzed.The algorithms of multiple table hiding and table in-out management are designed in detail to obtain the change route of table operating states.So,the algorithms can be available for all kinds of webpage structures of multiple tables and single table.The multiple tables can be composed with parallel table and embedding table.Experimental results show that the proposed approach is practical,secure and transparent.
