Abstract

The present invention relates to a gateway system which relays a request from a user for a service provided by another system and to a recording medium therefor. An object of the present invention is to provide a desired information service with a single user ID and password entered on the side of each user by transmitting a request from each user received by a gateway to another desired information provider server or gateway with the user ID and password being converted and by returning a response to the request to the user through a reverse conversion process when the response is received. The gateway system according to the present invention includes a unit which authenticates the user upon receiving the request from the user, a unit which makes the request using link information and authentication information corresponding to the requested service, and a unit which incorporates link information concerning the gateway system into link information included in returned data corresponding to the requested service.

Claims

1. A gateway system relaying a request from a user for a service provided by another system, the gateway system comprising:

an authentication unit which receives the request and authenticates the user;

a service request unit which makes the request to said another system on behalf of the user based on a result of an authentication by said authentication unit by accessing said another system via an Internet using a URL specifying said another system, using link information and authentication information corresponding to the requested service; and

an information link unit which incorporates link information concerning the gateway system into link information included in returned data corresponding to the request.

2. The gateway system as claimed in claim 1, characterized by having a plurality of systems each including said authentication unit, said service request unit, and said information link unit, the systems being provided in a hierarchical structure.

3. The gateway system as claimed in claim 1, characterized in that:

said service request unit comprises a table in which accessible service information retained by the user is entered, and makes the request for a service on behalf of the user when the service is accessible to the user.

4. The gateway system as claimed in claim 1, characterized in that:

said service request unit comprises a table in which an option ID serving as a billing unit is entered in correspondence to the system providing the service, and transmits the option ID in making the request.

5. The gateway system as claimed in claim 1, characterized in that:

said information link unit converts the link information included in the returned data into the link information concerning the gateway system, the link information included in the returned data being included in control information set in the returned data, the control information including access information of the user to a WWW server.

6. The gateway system as claimed in claim 2, characterized in that:

said information link unit converts the link information included in the returned data into the link information concerning the gateway system, the link information included in the returned data being included in control information set in the returned data, the control information including access information of the user to a WWW server.

7. The gateway system as claimed in claim 3, characterized in that:

said information link unit converts the link information included in the returned data into the link information concerning the gateway system, the link information included in the returned data being included in control information set in the returned data, the control information including access information of the user to a WWW server.

8. The gateway system as claimed in claim 4, characterized in that:

said information link unit converts the link information included in the returned data into the link information concerning the gateway system, the link information included in the returned data being included in control information set in the returned data, the control information including access information of the user to a WWW server.

9. A computer-readable recording medium:

having a program which causes a computer to execute the operations of;

authenticating a user upon receiving a request for a service from the user;

making the request to said another system on behalf of the user based on a result of authenticating the user by accessing said another system via an Internet using a URL specifying said another system, using link information and authentication information corresponding to the requested service; and

incorporating link information concerning a gateway system into link information included in returned data corresponding to the request.

10. The computer-readable recording medium as claimed in claim 9, wherein making the request to said another system includes use of a table in which accessible service information retained by the user is entered, and making the request for a service on behalf of the user when the service is accessible to the user.

11. The computer-readable recording medium as claimed in claim 9, wherein making the request to said another system includes use of a table in which an option ID serving as a billing unit is entered in correspondence to a system providing the service, and transmitting the option ID in making the request.

12. The computer-readable recording medium as claimed in claim 9, wherein incorporating the link information includes converting the link information included in the returned data into the link information concerning the gateway system, the link information included in the returned data being included in control information set in the returned data, the control information including access information of the user to a WWW server.

13. The computer-readable recording medium as claimed in claim 10, wherein incorporating the link information includes converting the link information included in the returned data into the link information concerning the gateway system, the link information included in the returned data being included in control information set in the returned data, the control information including access information of the user to a WWW server.

14. The computer-readable recording medium as claimed in claim 11, wherein incorporating the link information includes converting the link information included in the returned data into the link information concerning the gateway system, the link information included in the returned data being included in control information set in the returned data, the control information including access information of the user to a WWW server.

15. A method of relaying a request for a service provided by another system, comprising:

requesting for the service provided by said another system on behalf of an authenticated user upon receiving the user'"'"'s request including a URL specifying said another system; and

accessing said another system using the URL, link information and authentication information corresponding to the requested service and incorporating the link information in data returned to the user.
