Reversible data hiding and secure data or information in images is a method that hides information or data in digital images format then secret communication. It is a method to hide extra message into cover media with a reversible approach. Accordingly that the original image and data cover content can be absolutely restored after extraction data or information of the hidden message. Reversible information hiding (RDH) Message this could be done by choosing an encoding key. It is use to encode the initial data once encrypting the data or information hiding secret is used. This information hiding secret is embedded on the encrypted data. Steganography is the science which deals with the information hiding into digital medium. For unsecure communication channel, steganography is a better method than cryptography. In this technique, the secret information is embedded inside a host (cover) file such as audio, video, text or image and the resulting output file (known as stego-file) is perceptually similar to the host file.
