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 accident. 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. Some face recognition experiments are carried out as a SVM classification scheme to experimentally confirm the effectiveness of the proposed scheme.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告オーディオビジュアル複合情報処理（AVM）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2018-05-31","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1","bibliographicVolumeNumber":"2018-AVM-101"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":189592,"links":{}}
