A REVIEW PAPER ON DATA HIDING IN ENCRYPTED IMAGE USING LOCATION MAP

Abstract

In recent decades, researchers have attracted considerable attention to the visual privacy of digital data, especially in cloud-based services. It is not possible to disregard the usefulness of Reversible Data Hiding in Encrypted Images (RDHEI) as it satisfies visual privacy and data security requirements. It typically comprises the content creator, data hider, and receiver of three distinct stakeholders. Using the encryption function, the original image is encrypted by the content owner. There is still a chance for the data hider/cloud owner to embed the additional data in it after encryption. The embedded data and the original image are retrieved losslessly at the receiver end. In our suggested RDHEI method, the room is reserved by the content owner for the data concealed before image encryption.
