Abstract

A control unit issues temporary authentication information for disabling a locking/unlocking process to a user terminal satisfying a first condition. The control unit determines whether first authentication information has been issued to another user terminal, issues second authentication information to the user terminal to which the temporary authentication information has been issued when the first authentication information has not been issued to another user terminal, and issues the second authentication information to the user terminal to which the temporary authentication information has been issued with detection of ending of use of the first authentication information in another user terminal as a trigger when the first authentication information has been issued to the other user terminal.

First claim

What is claimed is:

1. An authentication information control system that controls a user's access to a predetermined area in a vehicle or a facility by issuing predetermined authentication information for enabling a locking/unlocking process using a locking/unlocking control device, the authentication information control system comprising:
a control unit configured to:
issue temporary authentication information to a user terminal satisfying a first condition, and
issue second authentication information when a distance between the user terminal to which the temporary authentication information has been issued and the vehicle or the facility becomes less than a first distance.

2. The authentication information control system according to claim 1 , wherein the control unit is configured to not perform a process of invalidating the second authentication information on the user terminal until a predetermined time elapses after ending of use of the second authentication information in the user terminal has been detected.

3. The authentication information control system according to claim 2 , wherein the user terminal invalidates an unlocking process using the locking/unlocking control device and validates a locking process in a period of time from the detection of the ending of use of the second authentication information in the user terminal to execution of the process of invalidating the second authentication information.

4. The authentication information control system according to claim 1 , wherein the control unit is configured to:
set a validity period of the second authentication information at the same time as issuing the second authentication information to the user terminal, and
detect ending of use of the second authentication information in the user terminal when the validity period expires.

5. The authentication information control system according to claim 1 , wherein the control unit is configured to:
set a validity period of the temporary authentication information at the same time as issuing the temporary authentication information,
determine whether a time remaining until the validity period of the temporary authentication information expires is less than a predetermined time length when the distance between the user terminal to which the temporary authentication information has been issued and the vehicle or the facility becomes less than the first distance, and
not issue the second authentication information to the user terminal when the remaining time is less than the predetermined time length.

6. An authentication information control method of controlling a user's access to a predetermined area in a vehicle or a facility by issuing predetermined authentication information for enabling a locking/unlocking process using a locking/unlocking control device, the authentication information control method comprising:
issuing temporary authentication information to a user terminal satisfying a first condition; and
issuing second authentication information when a distance between the user terminal to which the temporary authentication information has been issued and the vehicle or the facility becomes less than a first distance.

7. The authentication information control method according to claim 6 , further comprising not performing a process of invalidating the second authentication information on the user terminal until a predetermined time elapses after ending of use of the second authentication information in the user terminal has been detected.

8. The authentication information control method according to claim 7 , wherein the user terminal invalidates an unlocking process using the locking/unlocking control device and validates a locking process in a period of time from the detection of the ending of use of the second authentication information in the user terminal to execution of the process of invalidating the second authentication information.

9. The authentication information control method according to claim 6 , further comprising:
setting a validity period of the second authentication information at the same time as issuing the second authentication information to the user terminal, and
detecting ending of use of the second authentication information in the user terminal when the validity period expires.

10. The authentication information control method according to claim 6 , further comprising:
setting a validity period of the temporary authentication information at the same time as issuing the temporary authentication information,
determining whether a time remaining until the validity period of the temporary authentication information expires is less than a predetermined time length when the distance between the user terminal to which the temporary authentication information has been issued and the vehicle or the facility becomes less than the first distance, and
not issuing the second authentication information to the user terminal when the remaining time is less than the predetermined time length.

11. A non-transitory computer readable medium storing a program for controlling a user's access to a predetermined area in a vehicle or a facility by issuing predetermined authentication information for enabling a locking/unlocking process using a locking/unlocking control device, the program causing a computer to perform a method, the method comprising:
issuing temporary authentication information to a user terminal satisfying a first condition; and
issuing second authentication information when a distance between the user terminal to which the temporary authentication information has been issued and the vehicle or the facility becomes less than a first distance.

12. The non-transitory computer readable medium according to claim 11 , the method further comprising not performing a process of invalidating the second authentication information on the user terminal until a predetermined time elapses after ending of use of the second authentication information in the user terminal has been detected.

13. The non-transitory computer readable medium according to claim 12 , wherein the user terminal invalidates an unlocking process using the locking/unlocking control device and validates a locking process in a period of time from the detection of the ending of use of the second authentication information in the user terminal to execution of the process of invalidating the second authentication information.

14. The non-transitory computer readable medium according to claim 11 , the method further comprising:
setting a validity period of the second authentication information at the same time as issuing the second authentication information to the user terminal, and
detecting ending of use of the second authentication information in the user terminal when the validity period expires.

15. The non-transitory computer readable medium according to claim 11 , the method further comprising:
setting a validity period of the temporary authentication information at the same time as issuing the temporary authentication information,
determining whether a time remaining until the validity period of the temporary authentication information expires is less than a predetermined time length when the distance between the user terminal to which the temporary authentication information has been issued and the vehicle or the facility becomes less than the first distance, and
not issuing the second authentication information to the user terminal when the remaining time is less than the predetermined time length.
