Lee and Huang proposed a dual-image reversible data hiding method to protect the confidential data in 2011. The image quality obtained by the method is good because each pixel in the cover image is modified by only adding or subtracting one to generate the stego image. However, in their method, each set of four cover pixels can only embed five confidential bits, thereby restricting the embedding rate. To overcome the above drawback, this work develops a reversible data hiding method based on… CONTINUE READING
