A Reversible Data Hiding Scheme Using Cartesian Product for HTML File

Many data hiding techniques using digital images as cover media were presented in past years. Nowadays, mobile devices become popular in the modern life. To develop a low computation cost data hiding technique is quite important research issue for delivering secret data. In this paper, a data hiding scheme for HTML files by using Cartesian Product strategy is presented. The right receiver can easily extract a secret message from a stego HTML file by parsing the source code of the stego HTML file. We collect the special blank character codes and segment the English sentence in cover HTML into several textual segments. Every textual segment contains some blank character (between-words location). Then, Cartesian production is used to generate the pairs of special blank character codes. Finally, replace the blank character by using selected special blank character code pair (i.e., according to secret bits) to imply secret.
