Using a Parser for Steganography Purpose


Steganography techniques or information hiding are concerned with hiding the existence of data in other cover media. Usually one hiding method is used to hide secret data in a cover text and that will reduce the security, so in this paper we will use more than one hiding method to hide secret data according to syntax grammars of cover text produced by a special parser. We represent the Arabic language grammar as logical terms and use B+tree for storing, and Augmented Transition Network) ATN) for parsing. The proposed technique was implemented using Visual Prolog and after testing according to the authorized measures that are used in this field The proposed approach has provide good security (transparency) for steganography.
