• This paper proposes a new data hiding method for binary images using pixel-value weighting. The binary cover image is partitioned into non-overlapping sub-blocks and finds the most suitable position to embed a secret bit for each sub-block. The proposed method calculates a weighted value for a sub-block to pivot a pixel to be changed. This improves the image quality of the stego-image. The experimental results show that the proposed method achieves good visual quality.
