Reversible data hiding scheme can recover the original image without any distortion from the marked image after the hidden data have been extracted. Several key concepts has been developed in literature, among them public key modulation is a technique used for reversible image data hiding schemes. However it increases time consumption and computation complexity. So in this project, a reversible data hiding (RDH) algorithm with histogram based contrast enhancement technique is proposed for images. For contrast enhancement Gaussian Mixture Model based Contrast Enhancement algorithm is used which enhances the contrast of a image to improve its visual quality. The highest two bins in the histogram are selected for data embedding so that histogram equalization can be performed by repeating the process. The original image is recovered when the side information is along with the host image.
