use of biometric authentication, which has both high convenience and high security, is advancing. In particular, empty-handed authentication, in which identity verification is performed only with biometric information without entering ID information, is attracting attention as payment at stores and entrance / exit management of offices, and the number of users is expected to increase. However, since empty-handed authentication requires matching with the biometric information of all registrants, as the number of users increases, the authentication processing time also increases, leading to an increase in server load and system cost. Therefore, in order to speed up the authentication process and reduce the load, there is a method (cache authentication) that caches the registered biometric information of a person who frequently uses a certain authentication point in advance and authenticates it, but it is a simple method. The user who visits the point first is not subject to this effect, and there is a limit to the improvement of the cache hit rate. In this paper, we propose a method that allows even first-time users to enjoy the effects of cache authentication by clustering multiple authentication points based on the authentication service usage history. In the evaluation experiment, the effectiveness of the algorithm was shown by comparative evaluation with the conventional method using the store visit data that regards the user's location information data as a store visit.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告コンシューマ・デバイス＆システム（CDS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2022-06-02","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"8","bibliographicVolumeNumber":"2022-CDS-34"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":218231,"updated":"2025-01-19T15:13:23.995260+00:00","links":{},"created":"2025-01-19T01:18:38.505999+00:00"}
