Abstract:

While transmitting information over untrusted networks the security of the transmitted information is very vital.For this purpose a new approach for reversible data hiding in encrypted image (RDH-EI) with sequential recovery is proposed here. The overall framework consist of a content owner, a data hider and a remote recipient. The content owner encrypts an appropriate cover image for the secret data hiding and data hider embed a confidential data within this using a embedding key where the recipient can access the information only when the encryption and embedding key is obtained. While majority of the existing approaches utilize only direct decryption of the message, we propose to do the recovery by a sequential method where the quality of the recovered image is improved. This proposed technique is a novel approach to hide confidential data within RGB images for increased embedding capacity and increased recovered image quality.
