Reversible data hiding has attracted more and more attention in both researches and applications. It can be categorized into two branches, one is histogram-based scheme, and the other is performed by adjusting the difference between adjacent pixel pairs. We consider the :advantages of both methods and integrate them altogether., and propose the histogram-based difference expansion scheme for reversible data hiding. Simulation results demonstrate the superiority and ease of implementation of the proposed algorithm.
