Separable Reversible Data Hiding Technique Based on Rgb-lsb Method

ABSTARCT: Communication over the internet is facing some problem such as data security, copyright control, data size capacity, authentication etc. Here we introduce a novel scheme for separable reversible data hiding in encrypted domain in which we use image as a cover medium. This paper illustrates the various objectives of implementing separable reversible data hiding technique. The separable reversible data hiding is consists of three steps in the first step; a content owner encrypts the image using an encryption key. Then, a data-hider compresses the encrypted image using a data-hiding key. The third step is to extract the additional data and recover the original image. The activities i.e. extracting the additional data and recover the original images are depends upon which key the receiver has. There is separation of these two activities according to availability of keys. The scheme’s main feature is the way of data embedding into the encrypted image using the different positions of LSB within image. Here we are concentrating on using RGB-LSB method for data embedding and finally verifies the performance of using RGB-LSB method in terms of data capacity, image quality etc.
