Abstract(in English)	In this report, a digital watermark for color picture using patchwork method is proposed. In the new method, a watermark is embedded on each of Y, Cb, and Cr components of a color picture. The watermark information on Cb and Cr components is expressed as a phase information of a vector in the Cb-Cr plane. As the result of computer simulation, it is found that the new method can embed more information, and have the tolerance over JPEG compression and brightness or color tone correction.
