RSA Based Secured Image Steganography Using DWT ApproachAbstract: The need for keeping safe secrecy of secret and sensitive data has been ever increasing with the new developments in digital system. In this paper, we present an increased way for getting embedding encrypted secret facts in gray scale images to give high level safety of facts for news over unsecured narrow channels Cryptography and Steganography are two closely related techniques are used in proposed system. Cryptography gets into making one of religion the secret note into a non-recognizable chipper. Steganography is then sent in name for using Double-Stegging to fix this encrypted data into a cover thing by which something is done and keeps secret its existence.
