RDH in Image with Asymmetric Key Cryptography

Reversible Data Hiding technique (RDH) is an approach to embed secret data into the encrypted original cover image. The confidentiality must be there when the secret media is transmitted to the receiver via network. This paper proposes a new framework for embedding the secret data into the image with the combination of RDH technique with asymmetric key cryptography to gain high security. It achieves perfect extraction of data and quality original image retrieval on decryption process. Thus this system will gain maximum efficiency and maintain high secrecy for both data and image than the existing RDH systems
