Authentication apparatus, authentication method, and non-transitory computer-readable storage medium

An authentication method, executed by a computer, comprising:

• acquiring master biological information of a target person from a mobile terminal, and acquiring biological information for authentication being biological information of the target person generated by a biological information generation apparatus installed at an entrance of a target area;
• authentication processing of executing authentication processing for the target person, by using the biological information for authentication and the master biological information;
• executing, in response to the authentication processing being successful, at least a part of processing for enabling the target person to enter a target area;
• and
• causing, in response to the authentication processing being successful, a storage unit to store the master biological information, and also invalidating or deleting, from the storage unit, the master biological information in which a time of being stored in the storage unit is equal to or more than a predetermined time,
• the authentication method further comprising,
• by the computer:
• in the acquiring, acquiring, before acquiring the master biological information from the mobile terminal, the biological information for authentication;
• in the executing authentication-processing, authenticating, for the master biological information which is valid and stored in the storage unit, the biological information for authentication;
• and
• in the acquiring, acquiring the master biological information from the mobile terminal in response to the master biological information which is valid and matched with the biological information for authentication not being stored in the storage unit.

A non-transitory computer-readable storage medium storing a program for causing a computer to execute a method comprising:

• acquiring master biological information of a target person from a mobile terminal, and acquiring biological information for authentication being biological information of the target person generated by a biological information generation apparatus installed at an entrance of a target area;
• executing authentication processing for the target person, by using the biological information for authentication and the master biological information;
• executing, in response to the authentication processing being successful, at least a part of processing for enabling the target person to enter a target area;
• and
• causing, in response to the authentication processing being successful, a storage unit to store the master biological information, and also invalidating or deleting, from the storage unit, the master biological information in which a time of being stored in the storage unit is equal to or more than a predetermined time, wherein:
• in the acquiring, before acquiring the master biological information from the mobile terminal, the biological information for authentication,
• in the executing authentication processing, executing, for the master biological information which is valid and stored in the storage unit, authentication processing for the biological information for authentication, and
• in the acquiring, acquiring the master biological information from the mobile terminal in response to the master biological information which is valid and matched with the biological information for authentication not being stored in the storage unit.
