| Abstract: | In order to protect the digital product copyright, the digital watermark algorithm is studied by changing its DCT important coefficient and the method to discriminate watermark in the image. Experiment result shows that the algorithm has robustness and perpetual invisibility even if the embedded digital image is processed by the common method such as cutting,noise interfering and rotating etc. |

| Keywords: | discrete cosine transform discrete wavelet transform digital watermarks robustness |
