Steganography are the most popular or widely used information security scheme or techniques. It is the act of covert communications. The algorithms for hiding data or message in a cover image, and extracting a message from a stego-image were implemented using C# programming language. In this paper, LSB Replacement technique was adopted as the embedding method. In this paper we propose a reversible high capacity data hiding method applying on binary images. We also proposed leakage detection and prevention with the help of unique hash values of the document/images. The paper proposes a novel framework for reversible data hiding in encrypted image (RDH-EI) based on reversible image transformation (RIT). Different from previous frameworks which encrypt a plaintext image into a cipher text form; RIT-based RDH-EI shifts the semantic of original image to the semantic of another image and thus protects the privacy of the original image. In our proposed system, we proposed a new mosaic image technique in which we divide the image/pdf document into parts, and the parts will then transformed, encrypted and encoded into target images. Steganography meaning covered writing. It includes the concealment of information within computer files. It is one of the techniques used for securing data or information over the internet.
