Service providing method, system and program

Abstract

In a single-sign on system provided, being prevented from centralization of communication load and processing load onto a central system, with taking security and privacy into the consideration, an authentication portion of a field server makes check on an authentication information received from the portable terminal. A ticket issue portion issues a ticket, and then registers it in a ticket DB, as well as, transmits to the portable terminal. Receiving a permission certificate and the ticket from the portable terminal, a service provider portion provides service to the user within an area permitted by the permission certificate, while the ticket issue portion issues a new ticket to be transmitted to the portable terminal, when the ticket received is correct one. A past record inquiring portion gives an inquiry on correctness of the ticket to that field server when receiving the ticket issued by other field server.

Description

technical field [0001] The present invention relates to a mobile tracking type service provision system capable of reducing the service utilization burden of users who use distributed services, and more particularly to a mobile tracking type service providing system that can safely use various services in places with different public spaces such as office buildings and station buildings. service delivery system. Background technique [0002] The importance of access control centered on personal authentication has been recognized in an environment where services are provided using information processing devices. Although authentication is implemented by presenting and confirming authentication information such as passwords, in an environment where various services are distributed over the network, whenever an attempt is made to use a service, authentication information is required to be presented many times, thereby increasing user authentication. Information input burden. ...

Problems solved by technology

That is, all requests must be directed to the authentication department. When the number of users increases or application services are scattered in a large area, the communication load for access in the authentication department and the processing load on the authentication department will increase. to increase

[0006] In addition, when a system such as an infrared ID such as a radiation active mark is used for seamless authentication, there is a problem that a third party maliciously copies the infrared ID and uses it for illegal purposes

In addition, a system in which the user's location is centrally monitored is not suitable from the viewpoint of user privacy protection.
