摘要：In this paper, a reversible data hiding scheme based on two dimensional difference histogram modification is proposed. We adopted difference-pair- mapping (DPM) strategy. A sequence of pairs of difference values is calculated by taking each pixel-pair and its surroundings. Then, a two-dimensional difference-histogram is produced by counting the frequency of the resulting difference pairs. Then, according to a particularly designed DPM, a reversible data embedding (RDH) is implemented. We have presented a method of data hiding in which the average embedding capacity is inceased. Experimental results have been compared with Li et al. method and found significant increase in embedding capacity of the algorithm.
