Data hiding using histogram modification of difference in medical images based on block division

In this work, data hiding method by modifying histogram of medical images and differences based on block division is proposed. Reversible data hiding by using histogram modification method considers the differences of the pixels which increases data hiding capacity. In our present study to enhance the data hiding capacity the block division method is preferred. In comparison to current algorithms, the proposed method shows a simple and effective data hiding for medical images with high image quality.
