A Secure Approach for Reversible Data Hiding using Visual Cryptography

Abstract

Data is the essential part of communication between sender and receiver. So it needed to be secure and authenticated.Number ofapproaches like Cryptography, Steganography can be used to achieve security of data. Cryptography refers to the study of mathematical techniques and related aspects of Information Security like data confidentiality, integrity and authentication. RDH is gaining lot of importance. RDH is nothing but securely transmitting data inside a cover file, such that data and cover file can be properly recovered at the receiver.This paper gives a keyless reversible data hiding techniquebefore image encryptionto make data hiding process effortless. Also visual cryptographic approach is used for encryption which helps to protect the image during transmission.
