のユーザの入札を利用したタスク実行ユーザ決定過程において，ユーザの入札情報にはセンシティブな情報が含まれており，そのような情報をプラットフォームに対し知られてしまうことが，ユーザの MCS 参加への妨げになっている．関連研究では，プラットフォームに対し，ユーザの入札値のみを秘匿化したオークションによるタスク実行ユーザ決定手法が存在するが，ユーザが入札したタスクを秘匿化することは考慮されていない．また，入札値の秘匿化の下，個人合理性を満たすように全ユーザの入札値以上の報酬額を与えるため，総報酬額が高くなってしまう．本稿では，モバイルクラウドセンシングにおける入札情報を秘匿化したオークションによるタスク実行ユーザ決定手法 DTU-AOBI（A Method for Deciding Task Execution User Using Auctions with Obfuscated Bidding Information）を検討する．DTU-AOBI では，差分プライバシ性を保証した秘匿化メカニズムにより入札情報を秘匿化し，総報酬額を抑えたタスク実行ユーザ決定手法を目指す．また，個人合理性，正直性，計算効率性を考慮したオークションによるタスク実行ユーザ決定手法を考案する．","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告モバイルコンピューティングと新社会システム（MBL）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2021-11-30","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"9","bibliographicVolumeNumber":"2021-MBL-101"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":214232,"links":{}}
