Abstract: Using Reversible Data Hiding concept system can provide security, authentication to the information system. Data hiding cannot recover original cover. While Reversible data hiding is a novel concept, which can recover original cover without any loss of image. With Reversible Data Hiding (RDH) the proposed system can perform embedding operation after encryption. In this technology initially image owner creates space for embedding additional data and then encrypts the original image after that data hider module embed additional data in the space created in the encrypted image. At the receiver side, host can extract the data and additional data and recover original message. This concept improves payload & security of the system. This is the basic theme of this concept. Basically this work describes the survey of the reversible data hiding techniques, related methods and procedures that have been developed with the subject.
