Therefore, as secure and convenient user authentication means on a smart-phone, biometric authentication based on biometric information obtainable from a touch panel which is a common user interface in the smart-phone has attracted much attention. On the other hand, in biometric authentication, various methods have been proposed to securely manage and operate a biometric template that stores a user's biometric information as template-protection technologies. In the biometric authentication using template-protection technologies, it is possible to authenticate a user while concealing biometric information. In various template-protection technologies, the biometric information must be converted into a set of values on a finite field (hereinafter, called biometric bit strings). However, with the many current methods, individuality is lost when the biometric information is converted into biometric bit strings, which may degrade authentication accuracy. Therefore, to design a more secure and convenient template protection method for smart-phones, we propose a method to generate biometric bit strings from flick operation which is a major means of inputting characters on the smart-phone and demonstrate its effectiveness through some simulation experiments.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"2126","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"2118","bibliographicIssueDates":{"bibliographicIssueDate":"2019-12-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"12","bibliographicVolumeNumber":"60"}]},"relation_version_is_last":true,"weko_creator_id":"33195"},"id":201521,"updated":"2025-01-19T20:59:43.578582+00:00","links":{},"created":"2025-01-19T01:04:46.953710+00:00"}
