| Abstract(in English) | We propose a method that introduces an auto-associative memory model to Shimana and Kawamura's method that utilizes a hetero-associative memory model to perform the zero-watermarking method. The zero-watermarking method is a watermarking method that preserves the original image by not embedding the watermark into the image. Since one image is associated with one watermark, it becomes difficult to manage the correspondence when handling a large number of images. Shimana and Kawamura's method is able to manage a large number of correspondences by using a hetero-associative memory model. However, when images are heavily attacked, the features of the images are also degraded. Therefore, the hetero-associative memory model cannot be correctly retrieved them. In this research, we propose a method that introduces an auto-associative memory model. Hence, even if the watermark cannot be correctly recalled by the hetero-associative memory model, the error can be successfully corrected by the auto-associative memory model. The proposed method was evaluated for the cases of JPEG compression and additive white Gaussian noise. As a result, the proposed method was able to reduce the errors of the watermark more effectively than the conventional method. |
