Information Security has been one among the largest challenges during this digital era. Images are assisting disproportionately in electronic communication during this digital aeon. Somebody transmits private images over a flabby communication network at times, absolute security is an accost argument to maintain image privacy. Encryption is one of the methods for gripping image reticence. Image encryption adds to the charter security of a preeminent bite for safe transmission of view over the net. For example, medical images, forensic images, military images etc. are such sensitive images where a minimum distortion can lead to the incorrect diagnosis. Thus, these type of images needs security, a proper authentication process, data hiding mechanism for hiding sensitive data, and overall maximum reversibility of the cover image. In digital image systems reversible data hiding has its own importance. Numerous techniques of data hiding are used for digital image hiding, among which RDH is best fit technique for lossless recovery privacy protection. In various image domains such as, compressed and uncompressed, most RDH techniques are proposed. RDH is more significant in terms of its efficiency and applicability for natural uncompressed image domain. The present RDH algorithms on digital image are outlined in this paper.
