Abstract
The present invention provides a system and a method, in which after authenticating a device, the user authentication methods are switched and used. Specifically, in performing user authentication via a terminal apparatus, the terminal apparatus is authenticated first and then based on this authentication result, a practical use of the terminal apparatus is determined, and the user authentication methods are switched so as to suit this practical use and the resultant method is implemented.
Claims11
A center apparatus for providing a service to a terminal apparatus, comprising:
- a communication unit which transmits/receives data;
- a terminal apparatus information DB which stores a practical use for each terminal apparatus;
- an authentication policy DB having a plurality of combinations of practical uses and authentication methods of the terminal apparatus registered therein as an authentication policy;
- an authentication method determining unit which determines a user authentication method from the authentication policy registered in the authentication policy DB;
- an authentication processing unit which performs authentication processing according to a user authentication method determined by the authentication method determining unit;
- and
- a service providing unit which provides a service to the terminal apparatus if the authentication processing is successful.
A terminal apparatus which enjoys a service provided by a center apparatus, the terminal apparatus comprising:
- a communication unit which transmits/receives data to/from the center apparatus;
- a data transmission/reception unit which transmits/receives data to/from a user device;
- a terminal apparatus information unit which stores terminal apparatus information of the terminal apparatus;
- an authentication processing unit which performs authentication processing according to an authentication request of the center apparatus;
- and
- a service enjoying unit which enjoys a service provided by the center apparatus if the terminal apparatus is authenticated by the center apparatus through the authentication processing.
An authentication system wherein a center apparatus authenticates a user using a terminal apparatus in order to provide a service, wherein the terminal apparatus comprises:
- a terminal apparatus information unit which stores terminal apparatus information of the terminal apparatus;
- and
- a service enjoying unit which enjoys a service provided by the center apparatus, wherein
- the center apparatus comprises:
- a terminal apparatus information DB which stores a practical use for each terminal apparatus;
- an authentication policy DB having a plurality of combinations of practical uses and authentication methods of the terminal apparatus registered therein as an authentication policy;
- an authentication method determining unit which determines a user authentication method from the authentication policy registered in the authentication policy DB;
- an authentication processing unit which performs authentication processing according to a user authentication method determined by the authentication method determining unit;
- and
- a service providing unit which provides a service to the terminal apparatus if the authentication processing is successful.
