ID レス認証であるため，利便性が高い．さらに，生体情報を提示する際のユーザの心理的負荷が比較的小さいため，受容性にも優れる．しかし，掌紋認証では，撮影する度にユーザの手の姿形が異なるため，認証に用いる掌紋領域を安定して抽出することが難しく，認証精度が低下してしまう．さらに，ID レス認証であることは大きな利点であるが，登録された全ユーザの中から，生体情報を提示したユーザを特定する必要がある．現状，提示された生体情報と登録された全ユーザの生体情報に速度を重視した照合処理を適用することでユーザの順位付けを行った後，精度を重視した照合処理を行うことで真に正当なユーザか検証している．しかし，この順位付けにおいて全ユーザとの照合処理を必要とするため，認証速度にも課題を抱えている．ここで，Google  社が，マルチメディアデータを利用した機械学習用フレームワーク MediaPipe を公開している．本研究では，MediaPipe を用いて，画像中の手のひらから推定された 21 点の座標情報（骨格情報）を利用した各種課題の解決を検討する．掌紋認証は，手のひらを撮影して生体情報を取得することから，掌紋認証において MediaPipe は追加の機器を必要とせず，親和性が非常に高いと言える．本稿では，以上の課題の中でも，MediaPipe を用いて得られた骨格情報を用いて全登録ユーザの順位付けを行うことで，掌紋認証を高速化する基礎検討について結果を報じる．","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"7","bibliographic_titles":[{"bibliographic_title":"研究報告セキュリティ心理学とトラスト（SPT）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2022-07-12","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"34","bibliographicVolumeNumber":"2022-SPT-48"}]},"relation_version_is_last":true,"weko_creator_id":"44499"}}
