Security Enhanced RDH Image Steganography by RRBE

Saranya.M | Aswani.K

Abstract: These Steganography is the art of hiding the existence of data in another transmission medium to achieve secret communication and Reversible Data Hiding (RDH) in images is a technique by which the image can be retrieved back after extracting the secret messages embedded in it. The present methods involves reserving room for the secret message before encrypting the message into the cover image. so that the cover image can be effectively retrieved after extracting the secret message by the receiver. But the method involves some disadvantages which reduces the efficiency of this method. The primary disadvantage that the key generation used in Reversible data hiding method is by using random value. When the random value is used in key generation, it can be effectively regenerated by the invaders. So this proves to be inefficient in security. In this paper we propose a new method in which we make use Rivest-Shamir-Adleman algorithm for the key generation which effectively increase the security as the key generation is difficult. This method can also be used to encrypt the message in the video also. The security is highly improve in the new method which is proved by using various experiments.
