A data hiding method using 3-directional pixel-value differencing for gray images is presented in this paper. The cover image is divided into non-overlapping 2 x 2 sub-blocks and the basis pixel is selected to calculate different three values of a sub-block. Difference values are replaced by embedding the number of secret bits that is referenced by the range table. For three pixel pairs in the sub-block, the optimal pixel adjustment is preceded to reduce the distortion of visual quality. The experimental results demonstrate that the proposed method provides a high capacity and good visual quality.
