Security of Information Using Cryptography and Image Processing

Mrunalinee Patole ^[4] | Sheela A Bankar

Abstract: In this paper we propose a same technique of sending confidential information using encryption and data hiding concept with different encryption algorithms; that is for image encryption we use AES algorithm and for data encryption we use Twelve Square cipher substitution algorithm; and try to improve the security mechanism. With plain text data we also consider the confidential audio and video data for embedding purpose. This work also proposes a scheme for separable reversible data hiding in encrypted image which is remove the drawback of non separable reversible data hiding in encrypted image.

Keywords: Image encryption, Decryption, twelve square cipher, reversible data hiding, non-separable reversible data hiding
