Abstract(in English) | In this paper, we propose a SVM computing scheme with EtC images, and evaluate the effectiveness of the proposed scheme, where EtC images are images encrypted by the method, which has been proposed for Encryption-then-Systems with JPEG compression. Recently, cloud computing is 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 accidents. Because of such a situation, this paper considers privacy-preserving SVM computing. It is shown that generating EtC images is reduced to a generation scheme using an unitary transform matrix under the use of z-score normalization of the data, so it does not effect the accuracy of SVM computing, even when most of kernel fuctions are used. In addition, we propose a scheme for reducing the number of dimensions from EtC images directly by considering the block size used for encryption.The proposed scheme allows us to obtain the same results as those computed from unencrypted images with redued dimensions.Some face recognition experiments are carried out as a SVM classification scheme to experimentally confirm the effectiveness of the proposed scheme. |
