| Abstract(in English) | We propose the new digital watermarking method using two-dimensional smearing transform to detect information in magnified image. This method can be detected signature information from enlarged image included it by using two-demensional smearring-desmearing transform, of which new smearing-desmear coefficients are defined. Finally, we present the efficacy of this method. |
