3-dimensional difference histogram modification for reversible data hiding is a technique, in which a reversible data hiding scheme is proposed by using difference-pair-mapping for 3-d images. For each pixel pair, it calculates the differences of neighboring pixel values and selects some difference numbers for difference expansion. Then, a three-dimensional difference-histogram is generated. Finally, reversible data embedding is implemented according to the improved difference pair mapping and LSB method. In 3-d difference histogram modification for reversible data hiding, a separable reversible data hiding is implemented.
