英文摘要In order to embed more reversible watermarking information for resolving the threat of easy copying and tampering in digital copyright issue, a new method of reversible data hiding algorithm based on pixel block prediction-error expansion is proposed. Firstly, the cover image is divided into blocks and every block is made with seven consecutive pixels. Secondly, in every image block, the relation of the five pair prediction-errors is used to embed watermark information. In the best case, pixel value of each image block is changed by 1 and each image block can be embedded 10 bits information. So, embedding capacity is effectively increased. Experimental results also demonstrate that the proposed method can achieve high embedding capacity and low computational complexity. Copyright © 2015 Binary Information Press.
