Adjacent Quad Modification Algorithm for Reversible Data Hiding

Reversible data hiding has been a newly developed branch in data hiding researches. With the definition, when the message is hidden into the original image by some means, the image containing the hidden message is transmitted to the decoder. After decoding, both the original image and the hidden message should both be recovered perfectly. In this paper, we make use of the easily implemented scheme by modifying the histogram of original image, and perform data hiding with the proposed scheme by considering the local statistics in the original image. Simulation results demonstrate the better performance, and hence the effectiveness of the proposed algorithm.
