A biological information authentication device 1 includes a control unit 9 configured as follows: when authenticating biological information S1 with respect to registered biological information 90 which has been registered, if authentication is not established a predetermined number of times and the degree of similarity of the biological information S1 and the registered biological information 90is no more than a reference threshold value 92, an authentication threshold value 91, which is used for authentication, is changed so that authentication becomes more difficult. The biological information authentication device 1 can ensure security and improve operability.
本发明的生物体信息认证装置(1)的控制部(9)构成为:在基于所登记的登记生物体信息(90)的生物体信息(S)的认证中,在预定的次数的认证不成立并且生物体信息(S)与登记生物体信息(90)的相似度为基准阈值(92)以下的情况下,以使认证变得困难的方式变更用于认证的认证阈值(91)。生物体信息认证装置(1)能够在确保安全性的同时使操作性提高。
