A Reversible Data Hiding Scheme Based on Prediction Difference

Abstract

In this paper, we propose a new data hiding scheme based on prediction difference. The difference between prediction value and the real value in the corresponding position of the cover image is calculated, and the secret bits are embedded into the difference. That is changing or staying the original pixel of corresponding position in the original image to embed secret bits. Experimental results indicated that our scheme provides higher PSNR value with the same payload.
