Survey on a Highly Secured Reversible Data Hiding: Principles, Techniques and Recent Studies

Today data hacking is a very big problem in networking field. There are many security techniques available to solving this problem. There are many research processing techniques related to internet security, cryptography and steganography etc. One of these is datahiding, using this concept we can provide security, authentication to the 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) we can perform embedding operation after encryption. In this technology initially a content-owner encrypts the uncompressed original image after that data hider module compressed the encrypted image and creates space for embedding additional data. At the receiver side, host can extract the data and additional data and recover original message. This concept improves payload & security of the system.
