In this, paper we propose a novel hash-based approach for colour image steganography. As, the available approaches for colour image steganography are using chaos-based and symmetric-key based cryptographic algorithms are not efficient and good for bulky data. However, the hash-based algorithms based approaches are considerably better in terms of providing(More)
Image stegnography is an emerging field of research for secure data hiding for data transmission over internet, copyright protection, and ownership identification. A couple of techniques have been proposed for colour image stegnography. However, the colour images are more costly to transmit on internet due to their size. In this paper, we propose a new(More)
