Abstract
To provide an authentication device capable of performing authentication accurately even when biological information changes with time. An authentication device () includes an acquisition unit () configured to acquire biological information about a user; an authentication processing unit (); a storage unit () configured to store standard biological information and basic biological information; and a standard biological information updating unit (). When a difference between the standard biological information and current biological information is less than a first threshold, the authentication processing unit () determines that authentication is established. When the authentication is established by the authentication processing unit (), the standard biological information updating unit () updates the standard biological information according to the current biological information for which the authentication is established, based on the basic biological information and a second threshold.
