Abstract
Provided are an authentication device, an authentication system, and an authentication method, which are capable of increasing an authentication rate while suppressing an increase in a processing load. To solve this problem, the authentication device acquires a periodic temporal variation of an authentication rate, using history information stored in an authentication history storage unit storing a previous authentication result as history information, predicting whether or not a future authentication rate is lower than a previous value, based on the temporal variation of the authentication rate, and updates registration data regarding biometric information which has been registered, using input data regarding biometric information input from a user, when it is predicted that a future authentication rate will be lower than a predetermined value.
