(EN) The invention relates to an automatic transaction device, a biometric authentication unit, and a biometric authentication method. When authentication failures are caused by permanent errors caused at time of registration of biometric information, such as forgetting placement of fingers at time of registration or registration being carried out in an inappropriate state, or from temporary errors on the part of the person concerned, such as injuries to fingers or foreign matter or filth adhering to fingers, the likelihood that authentication will be determined to fail even after retrying the authentication is high. If the match degree of the biometric information is low, remains insufficient even after performing estimated cause and corrective steps in placement of fingers, and the cause of the lack of improvement lies with an error at time of registration, personal identifying material which the user supplied at time of registration of biometric materials is queried, and a re-registration of biometric information and transaction process carried out. If the cause of the lack of improvement lies with a temporary error on the part of the person being identified, the problem cannot be resolved at time of transaction, and thus, a migration is carried out to a restricted transaction after scanning the personal identifying material and querying and verifying same.

本发明的自动交易装置、生物体认证单元及生物体认证方法，在由于忘记生物体信息注册时手指的放置方法、或在不恰当的状态下进行了注册等的永久性注册时不良原因、手指损伤、或在手指上附着了异物或脏污等的暂时性本人原因而导致认证失败时，即使进行再认证也很可能判断为认证失败。在即使实施一致度低的推断原因和手指的放置方法的改善方案，生物体信息的一致度也不足的情况下，当未改善的原因是注册时不良原因时，在对照生物体信息注册时使用者所提交的本人确认资料的基础上，进行生物体信息的再注册及交易处理。另一方面，在未改善的原因是临时性本人原因的情况下，由于在该时刻不能解决，因此在读取本人确认资料来对照确认的基础上向限制交易转移。
