| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this paper, we propose a face recognition scheme using eigenface and kernel eigenface with EtC (Encryption-then-Compression) images, where EtC images are images encrypted by the method which has been proposed for Encryption-then-Systems with JPEG compression. Recently, cloud computing has been spreading in many fields. However, the cloud computing has some serious issues for end users, such as unauthorized use and leak of data, and privacy compromise, due to unreliability of providers and some accident. Because of such a situation, this paper considers a privacy-preserving face recognition method using eigenface and kernel eigenface. In this paper, we show inner products and euclidean distances between the centered vectors of pixels in EtC images are preserved, and the encryption steps do not affect feature vectors generated by eigenface and kernel eigenface. To evaluate the proposed method, we visually compare feature vectors generated from EtC images with ones generated from non-encrypted images. Moreover, a face recognition experiment is carried out under the use of a support vector machine algorithm. |
