The framework allows the authentication method to be dynamically adjusted based on the assessed risk. To implement risk-based authentication, we adopt behavioral biometric techniques such as keystroke dynamics. This approach makes it possible to detect unauthorized use of a device on which a FIDO authentication session remains active, without requiring explicit authentication actions from the legitimate user. As a preliminary investigation for the proposed framework, we conduct a comparative evaluation of keystroke authentication methods and discuss which techniques are most suitable for integration with FIDO authenticator.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"537","bibliographic_titles":[{"bibliographic_title":"コンピュータセキュリティシンポジウム2025論文集"}],"bibliographicPageStart":"530","bibliographicIssueDates":{"bibliographicIssueDate":"2025-10-20","bibliographicIssueDateType":"Issued"}}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2026-03-25T04:58:38.308684+00:00","updated":"2026-03-26T04:35:12.793489+00:00"}
