propose a method that dynamically generates secret questions from a user's location trajectory. Our proposed method aims at an authentication method that 1) does not require users to set up their own authentication information in advance, and 2) does not require permanent memory like passwords or static secret questions. The authentication system of the proposed method uses WebAuthn protocol and adapts dynamic questions based on location information as an authentication method for WebAuthn authenticators. In this paper, we conducted a lab study, generating questions from location trajectory obtained from its participants' smartphones as a preliminary experiment to implement the system. In addition, we conducted a qualitative evaluation of our proposed method through a questionnaire to the participants. As a result, we confirmed that our proposed method was accepted by the participants and identified issues for the implementation of the system, such as ones in creating questions.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告インターネットと運用技術（IOT）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2022-02-28","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"23","bibliographicVolumeNumber":"2022-IOT-56"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":216779,"updated":"2025-01-19T15:44:21.415135+00:00","links":{},"created":"2025-01-19T01:17:17.630222+00:00"}
