| Abstract(in English) | Among conventional watermarking systems using wavelet transform, it is shown that the one which embeds watermarking to lower frequency field is effective against alteration attack. But, since human's eye is very sensitive for noise on lower frequency field, the embeded watermarking itself causes some decline of the image. Thus we propose a new method of a watermarking system using wavelet transform. The system utilize Multi Resolution Representation repeatedly and embed the watermark into the edge parts of higher frequency field of each MRR level. We will show the efficiency and safety of our system by experiments. |
