| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We propose a image authentication using complex smearing-desmearing. The diffusion coefficient of complex smear transform is used as key infomation. Therfore,it is difficult for third party to specify watermarked information. Moreover, the detection rate of the authentication has been improved by using the phase of the complex impulse as watermarking information. We performed test, which show to be able to accurate image authentication cor alteration of copy \& paste. |
