Efficient Reversible Data Hiding Techniques Based on RDH Algorithm for Multimedia Communication

In the paper, we deal with the system that hides the data reversibly which is termed as reversible data hiding scheme. In this technique images will be authenticated and then the authenticate image is restored to their original from. This original form is achieved by removing the digital watermark and it replaces the image data that had been overwritten. The main aim of hiding is to maintain secret communication between two users. The U.S Army also uses this technique for authentication of reconnaissance images reversible technique. Because it has an advantages of high hiding capacity, high security, low complexity and good visual quality. Reversible technique is in the sense extraction of the original input image. Reversible data hiding finds many applications and widely used in the fields of medical imagery, military imagery and law forensics. Reversible data hiding is the best technique which provides more security for hiding information than the other techniques.
