Abstract—A method for improving the watermark extraction performance of the digital watermarking based on the modification of image pixels is proposed in this paper. By embedding a watermark signal with a multiple sections technique in the blue channel, the accuracy of the extracted watermark can be improved. Sets of experiment are carried out to prove our proposed concept. The obtained results show that the improved performance in term of NC, compared to the previous method, is achieved by using our proposed watermarking method. The improved robustness of the proposed method against various common imaging processing based attacks also performs better. Especially in cropping attacks, at cropping 50% the results significantly improve about 0.2 on average in terms of NC value compared to previous proposed algorithm.
