BLE を用いて取得する．その際，BLE で自分の名前をブロードキャストするとプライバシが保護されないので，時間経過で変化するランダムな識別子をブロードキャストする．また接触履歴から接触回数を取得するためには二者間での接触履歴を見せ合う必要があるが，接触履歴は個人情報である．そのため互いの接触履歴を暗号化した状態で共通要素を見つけることができる秘匿共通集合計算を用いて接触日時と回数を導出する．","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"7","bibliographic_titles":[{"bibliographic_title":"研究報告ヒューマンコンピュータインタラクション（HCI）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2023-11-14","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"36","bibliographicVolumeNumber":"2023-HCI-205"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":229402,"links":{}}
