recent years, ID / password is one of the widely used personal authentication methods, but the use of this method is troublesome. In order to solve this problem, we have been promoting research and experiments by proposing \"lifestyle authentication and analysis\" that considers human behavior habits as individual characteristics and uses it as an authentication factor. In 2017, we conducted experiments with 50,000 people and succeeded in acquiring various and large amounts of behavioral data. In addition, in January to April 2019, an experiment was conducted to visualize the authentication results of the individual as a demonstration experiment 2019 (step 1). In this experiment, we compared the template obtained from ordinary behavior data with the current behavior pattern and quantified it as a certified value. This paper summarizes the results obtained here.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"16","bibliographic_titles":[{"bibliographic_title":"コンピュータセキュリティシンポジウム2019論文集"}],"bibliographicPageStart":"9","bibliographicIssueDates":{"bibliographicIssueDate":"2019-10-14","bibliographicIssueDateType":"Issued"},"bibliographicVolumeNumber":"2019"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":201295,"links":{}}
