    We propose a watermarking method that has robustness against geometrical slight distortions. The method is based on the variances of Cb and Cr components of an image. When a color image is geometrically distorted, Cb and Cr components on the same position cause the same distortion, and so the relation of variances of Cb and Cr components in a local region does not change easily. We embed each bit of a watermark into some adjacent local regions by changing the variances of Cb and Cr components so that the watermark may be robust to geometrical distortions.
