Reversible Data Hiding With De and RW (De-Difference Expansion RW-Reversible Watermarking)

In the past two decades, Reversible Data Hiding (RDH) additionally mentioned as lossless or invertible knowledge concealing has gradually become a really active analysis space in the field of information hiding. In some sensitive scenarios permanent distortion is strictly prohibited. So, in order to solve this problem we go for Reversible Data Hiding (RDH). It proposed to embed the authentication information into a digital medium and enable the legitimate user to extract the embedded authentication information for verifying the authenticity of received data. The project focuses on imperceptivity of both hidden and act of data embedding. The history of technical developments , the current state of arts and possible future are presented and discussed. It is expected that Reversible Data Hiding (RDH)  technology and its application in the real world will continue to move ahead in a rapid manner thus providing efficient and advantage yielding results.
