A novel scheme of webpage information hiding based on attributes

Webpage based information hiding technology uses a webpage as the cover object. The research of this area has led to several different techniques, which can be broadly classified into embedding invisible characters based, switching the uppercase-lowercase states of letters in tag based, and altering the order of attributes based. Based on the attributes order, a scheme of information hiding is presented in this paper, which overcomes the drawback of the ability of imperceptibility and robustness of the traditional webpage information hiding algorithms. In the proposed scheme, a map between the set of all permutations of n-attributes and the set of all (n-1)-bit binary string is established first, then the embedding and extracting processes are achieved according to this map. The experimental results and analysis show that the proposed scheme dose not lengthen the size of the cover-webpage, and has better imperceptibility, more robust, and more perfect security than the traditional algorithms. The embedded capacity of the proposed scheme is large enough to embed specified secret data. So the proposed scheme can be used to protect the content of the webpage and covert communication.
