Abstract

An authentication system comprises a register image storage unit, which stores a pre-registered register image of a mobile terminal user; a communication control unit, which receives a moving image of the user transmitted from the mobile terminal; and an authentication processing unit, which authenticates the user by checking the moving image received by the communication control unit against the register image stored in the register image storage unit.

Claims

1. An authentication system comprising:

a register image storage unit, which stores a pre-registered register image of a mobile terminal user;

a communication control unit, which receives a moving image of the user transmitted from the mobile terminal; and

an authentication processing unit, which authenticates the user by checking the moving image received by the communication control unit against the register image stored in said register image storage unit.

2. The authentication system of claim 1, wherein the communication control unit receives the moving image while connected to the mobile terminal.

3. The authentication system of claim 1, wherein;

the register image storage unit connects and stores identification data for identifying the user with the register image;

the communication control unit receives the moving image and the identification data; and

the authentication processing unit authenticates by checking the moving image against the register image and the received identification data against the identification data stored in the register image storage unit.

4. The authentication system of claim 1, further comprising a starting condition storage unit, which stores the starting conditions for starting authentication;

wherein

the authentication processing unit authenticates based on the starting conditions stored in the starting condition storage unit.

6. The authentication system of claim 1, wherein, in the case that a checked result of the moving image against the register image does not identify the user as him/herself, the authentication processing unit performs re-authentication by using the moving image being received by the communication control unit and performing re-authentication.

7. The authentication system of claim 1, wherein the authentication processing unit acquires a static image from the moving image received by the communication control unit, and checks the acquired static image against the register image.

8. The authentication system of claim 1, further comprising a registration processing unit, which registers the register image received by the communication control unit in the register image storage unit, wherein

the communication control unit receives the register image transmitted from the mobile terminal.

9. The authentication system of claim 8, wherein:

the communication control unit receives the register image transmitted from the mobile terminal and identification data for identifying the user; and

the registration processing unit connects the identification data with the register image received by said communication control unit, arid stores these in the register image storage unit.

5. The authentication system of claim l, wherein the authentication processing unit accepts a request for authentication, and authenticates based on the accepted request.

10. A mobile terminal comprising:

a moving image acquisition unit, which acquires a moving image of the mobile terminal user; and

a communication control unit, which transmits the moving image acquired by the moving image acquisition unit to the authentication system, which authenticates the user.

11. The mobile terminal of claim 10, wherein the communication control unit transmits the moving image while connected to the authentication system.

12. The mobile terminal of claim 10, further comprising a register image acquisition unit, which acquires a register image of the user to be registered in the authentication system;

wherein

the communication control unit transmits the register image acquired by the register image acquisition unit to the authentication system.

13. An authentication method, comprising:

receiving, by an authentication system that authenticates a mobile terminal user, a moving image of the mobile terminal user transmitted from a terminal; and

checking the received moving image against a register image to authenticate the user by the authentication system, which stores the pre-registered register image of the user.

14. The authentication method of claim 13, wherein the authentication system receives the moving image while connected to the mobile terminal.

15. The authentication method of claim 13, wherein:

the authentication system connects and stores identification data for identifying the user with the register image;

the authentication system receives the moving image and the identification data; and

the authentication system authenticates by checking the moving image against the register image, and the received identification data against the stored identification data.

16. The authentication method of claim 13, wherein:

the authentication system stores a starting condition for starting authentication; and

The authentication system authenticates based on the stored starting condition.

17. The authentication method of claim 13, wherein:

the authentication system accepts a request for authentication; and

the authentication system authenticates based on the accepted request.

18. The authentication method of claim 13, wherein the authentication system performs re-authentication by using the received moving image when re-authentication is performed, in a case where a checked result of the moving image against the register image does not identify the user as him/herself.

19. The authentication method of claim 13, wherein the authentication system acquires a static image from the received moving image, and checks the acquired static image against the register image.

20. The authentication method of claim 13, wherein:

the authentication system receives the register image transmitted from the mobile terminal; and

the authentication system stores the received register image in the authentication system.
