摘要
通过网页传递秘密信息具有重要的意义。为了能够利用网页来传递秘密信息,通过对超文本标记的分析,对现有网页信息隐藏技术的研究,提出了一种全新的基于表格行列距属性的网页信息隐藏算法。算法规则依据表格中一行的相邻两列的宽度值的奇偶性和一列的相邻两行高度值的奇偶性。实验结果和分析表明,该算法的隐藏容量等于或略小于表格行数与列数之积,隐蔽性较好,也可以应用于网页内容保护。
It is of great significance to transmit the confidential information through the webpage. In order to transmit the confidential information through the webpage after analyzing HTML tags and researching the existing webpage information hiding technology, an completely new algorithm of webpage information hiding is presented based on the property of row and column in ta- ble. The rule relies on the parity of width value of two adjacent columns in one row, and relies on the parity of height value of two adjacent rows in one column. The experimental results show that the embedded capacity of the algorithm is equal to or slightly less than the product of the number of rows and the number of columns, which shows good imperceptibility. It could be also used to protect the content of a webpage.
