A Modified Approach to Text Steganography Using HyperText Markup Language

Steganography is the tactics of silent communication, where one person communicates with others through cover medium so that intermediary does not has suspicion about the hidden information. In this paper we propose a modified approach for text steganography based on HTML tags and attributes. As HTML is rich in tags and its attributes, easily communicated in the internet, and the source code is checked rarely by anybody it can be used intelligently to perform text steganography. By hiding the secret data inside the source code of HTML, text steganography can be easily achieved. In this approach the relation between two consecutive attributes is considered for hiding secret data. To hide ´1´ two consecutive attributes of same tag are taken, and to hide ´0´ two consecutive attributes of different tags are taken. The secret data hiding and revealing technique is presented. The proposed approach has been explained using java programming language.
