To provide an authentication system and authentication method capable of improving authentication accuracy.SOLUTION: An authentication system X comprises a database 13, a receiving unit, an authentication unit, and a transmitting unit. The authentication unit has: a first authentication method for authenticating an image subject P1 by collating all biometric information Ua with image information P1a; and a second authentication method that includes an individual authentication method for authenticating an image subject P2 by identifying registration information Ub corresponding to identification information P2b of the image subject P2 and collating the biological information Uat associated with the identified registration information Ub with the image information P2a. The second authentication method is executed when the receiving unit receives the identification information P2b of the image subject P2 together with the image information P2a.SELECTED DRAWING: Figure 3 【課題】認証精度を改善できる認証システムおよび認証方法を提供する。【解決手段】認証システムＸは、データベース１３と、受信部と、認証部と、送信部と、を備え、認証部は、全ての生体情報Ｕａと画像情報Ｐ１ａとを照合して被撮像者Ｐ１を認証する第一認証方式と、被撮像者Ｐ２の識別情報Ｐ２ｂに対応する登録情報Ｕｂを特定し、特定された登録情報Ｕｂに関連付けられた生体情報Ｕａｔと画像情報Ｐ２ａとを照合して被撮像者Ｐ２を認証する個別認証方式を含む第二認証方式と、を有し、第二認証方式は、受信部が画像情報Ｐ２ａと共に被撮像者Ｐ２の識別情報Ｐ２ｂを受信したときに実行される。【選択図】図３
