Abstract: Image steganography is the process of data hiding so that information can be transmitted in secure manner. In the process of data hiding various approaches had been used for data embedding. In this paper a novel approach has been proposed so that data can be easily embedded behind the cover pixels. In the process of data hiding data integrity and confidentiality are major concerns that must be accumulated. In proposed work encryption approach has been used so that data security from various attacks can be achieved. In the proposed work multiple bits have been used for embedding of encrypted information. Performance metrics has been analyzed for validation of proposed system. On the basis of these parameters one can conclude that proposed approach provide better results as compare to existing one.
