In this paper, an enhanced combined demosaicking and watermarking (CDW) method is proposed. Such a combination leads to lower power and time consumption comparing with being performed separately. In the proposed method, bits are arranged in a special order employing a Sudoku pattern. Results indicate that this arrangement increases robustness against JPEG compression attack.
