Abstract-In this paper, a new data hiding algorithm based on pixel pairs using chaotic map is proposed. Data hiding scheme is created by applying modulo function to pixel pairs. In here, pseudo random number generator (PRNG) is obtained from chaotic maps. The PRNG is very important for this algorithm since the data hiding coefficients are chosen by PRNG. For example, if the coefficient is 0, subtraction operator is used between pixel pairs. If coefficient is 1, summary operator is used for selected pixel pairs. The proposed algorithm is evaluated by embedding different sized secret data into different test images. This method is compared with the determined studies in the literature and the obtained results is evaluated. In this study, special rules are also defined to pixels which have boundary values for resolve overflow/underflow problem.Minimal changes are performed to reach the desired value of the pixel values. According to the results obtained, the proposed algorithm has high visual quality, good running time, secure and high payload capacity.

RDH is the technique of reversible data hiding. It maintains the original image losslessly retrieved after data embedded is obtained while protecting the image content's as confidential. In this survey paper, we studied different reversible data hiding methods. All existing methods embed data by reversibly vacating room from the encrypted images which may result into some errors on data extraction or image restoration. Also in literature survey it is shown that DE, interpolation technique, prediction and sorting, histogram modification are the generalized methods for hiding data, but these methods are implemented only in plain images. In recent past all these methods are used in encrypted images to enhanced security. All these methods have their own advantages but no single approach is feasible as well as applicable for all the case such as, data hiding, security & privacy, image recovery etc. We have analyzed that there is need of high security as well as maintaining quality of original image during transmission and exchange of image

To improve performance of reversing the order of encryption and vacating room is introduced in [12].
