Abstract :

Recently, more and more attention is paid to reversible data hiding (RDH) in encrypted images, since it maintains the excellent property that the original cover can be losslessly recovered after embedded data is extracted while protecting the image content’s confidentiality. All previous methods embed data by reversibly vacating room from the encrypted images, which may be subject to some errors on data extraction and/or image restoration. In this survey paper, we discuss about various methods and algorithms which were used for reversible data hiding (RDH) in encrypted image to make data hiding process effortless. We also use visual cryptographic approach for encryption which helps to protect the image during transmission. The scheme is suitable for authentication based application where collective acceptance and decision making plays an important role. The main goal is to retrieve the original image with lossless process and minimum computation during image encryption /decryption by using keyless approach. Keywords - Reversible Data Hiding, image encryption, Visual Cryptography, authentication, encryption/decryption.
