In this report, reversible data hiding (RDH) algorithm is proposed for digital images. Instead of trying to keep the PSNR value high, the proposed algorithm enhances the contrast of a host 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 side information is embedded along with the message bits into the host image so that the original image is completely recoverable. The proposed algorithm is used for two sets of images to demonstrate its efficiency. To our best knowledge, it is the first algorithm that achieves image contrast enhancement by RDH. Furthermore, the evaluation results show that the visual quality can be preserved after a considerable amount of message bits have been embedded into the contrast-enhanced images, even better than three specific MATLAB functions used for image contrast enhancement.

Cryptography is a technique for secret communication where as obscuring the secret communication using for different data is Steganography. The secret communication is carried through many sources like image, audio & video files. Our work is mainly proposing data hiding by embedding the message of interest using geometric style of cryptographic algorithm, thus providing high security. Wavelet and curvelet transform algorithms are used to perform preprocessing of images.Even if the image carrying embedded data i.e., Stego image undergoes a reverse operation and data cannot be extracted if the receiver is unaware of the exact coordinates of the geometric shape. Hence retrieving secret image for an attacker becomes a hard task. Our Experimental results are verified for both the properties of Cryptography and Steganography it may be applicable for kind of multimedia applications.

In recent years, due to explosive growth in the use of internet the security of sensitive data becomes one of the prime concern. For this various data hiding techniques are in used. Now a days reversible data hiding in encrypted images is in used due to its excellent property which is original cover can be recovered with no loss after extraction of the embedded data. Also it protect the original data. Previously all the methods use vacate room after the encryption (VRAE) method but the problem with that is sometimes errors are occurred at the time of recovery of original image. So we use reversible data hiding by reserving room before the encryption. Also we survey the reversible data hiding techniques with different algorithms used
