%X A digital watermarking method to resist geometric attack, mainly the scaling attack and the cropping attack, was presented. We used the method of embedding the watermarking to every block and the method of fixing a resisting scaling grid to be against the scaling attack and the cropping attack. The experiment proves that this method can recover the image, and can detect the watermark, and can effectively resist the scaling and the cropping attack.
