| Abstract(in English) | We propose a new smear-transformation method that can disperse a digital watermark to a whole image. Then, we propose the digital watermark method that used this smear-transformation. Except for quantumization error, in our method, we show that the quality of the image, in which be written the digital watermark, relys only on the size of the image and the strength of the watermark. Furthermore, we do a JPEG-tolerance test with a computer experiment. Finally, we present the efficacy of this method. |
