| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This study considers a template protection scheme based on an random unitary transformation, where the template consists of the features extracted from the biometric trait. In this paper, we apply the template protection scheme based on an unitary transformation to a kernel-based classification, and the recognition performance is theoretically considered. Previous studies showed that the Euclidean distance between templates protected by a unitary transform is the same as that between original ones, and there is no degradation of the recognition performances of using l2-norm minimization. In this study, we show a new property that there is no degradation of the recognition performances of using a kernel-based classification. The proposed method can obtain the same recognition performance as authentication with original templates even though protected templates are applied to the same procedure as the authentication with original templates. We perform some face recognition experiments of using a kernel eigenface as one of the kernel-based classification schemes experimentally to confirm the validity of the theory. |
