A Survey on Medical Images for Reversible Data Hiding Techniques

In the recent trends, technology has advanced so much that most of the individuals are using internet for communication purpose. It became very easy, accurate and fast to send data with the help of internet from one end to another across the world. The major issue while sending data over the internet is the security of the data whether it is personal or confidential. Many of the techniques are there for protecting the data, but data hiding is the most protective technique in data security. Basically, Data hiding is a technique in which secret data is embedded into the cover image and at the receiver side, the host will extract the secret data. Another technique is reversible data hiding (RDH) in which the host can extract the secret data as well as the original image without any loss of data. In this paper, we represent an overview of the recent research in the field of the reversible data hiding techniques, related methods and procedures.
