| Abstract(in English) | Most robust digital watermarking, which is based on orthogonal transform, has high security because signature data is embedded in the domain of transforms. We have suggested watermarking techniques based on the number theoretic transform which is a type of orthogonal tranform. The number theoretic transform can be calculated without round-off error arid has fragile nature of coefficient. In this paper, we introduce fragile and lossless watermarking techniques using the characteristics of the NTT. |
