Using of digital multimedia by sudden development of internet increases and unlawful reproduction also increases accordingly. To solve these problems, technology of watermarking have been taking an interest lately. In this paper, we studied about blind watermarking that do not need additional information in watermark detection. To control between quality and robustness of watermarked image, we propose the method using control variable at watermark insertion process. At watermark insertion process, control variable is determined by the statistical characteristics of image. Experiments show the relations between quality and robustness by insertion method of watermark that is proposed in this paper.
