Information stowing away and encryption are two important methods in information concealing. In the encryption strategies plain text is converted content into garbled figure message, the information stowing procedures implant more information into the source or picture by making slight changes. This paper presents lossless, reversible & joined information plans of hiding in image content figure scrambled in crypto systems of open key cryptography with homomorphic and the probabilistic properties in system. In the lossless phase, figure content pixels were supplanted with recent qualities for inserting data within a few least critical piece planes in figure content pixels with coding of wet paper in multi layers. It utilizes a novel reversed information hiding calculation, which can recover first picture from no twisting from stamped picture, after extraction of shrouded data. Reversible Data Hiding (RDH) in pictures was a method, by which the initial information can be recouped precisely after extraction of inserting message. JPEG RDH-EI work process incorporates three gatherings: content proprietor, data hider and beneficiary. In reversible phase, a pre-processing is utilized for shriveling picture histogram before picture encryption. By using similarity in reversible and lossless phases, the data hiding tasks in the two habitats will be same as performed with in an encoded image.
