Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an authentication system using an electronic card such as an IC card in which an ID has been entered, and particularly to an electronic card use authentication which simplifies management for both service providers and users. Regarding the system.

[0002]

2. Description of the Related Art Due to the rapid growth of the Internet and mobile phones, opportunities to receive various services face-to-face are increasing. Along with this, each person who receives a service has a personal authentication tool issued by each service company, and it is necessary to properly use these personal authentication tools for each service to be enjoyed. Furthermore, with the diversification of these service access means, the number of personal authentication tools that need to be managed tends to continue to increase, and it can be said that the number of personal authentication tools exceeds the range that can be managed by individuals.

Personal identification tools include bank cash cards, credit cards, and Internet service I
A D / password or the like is used, and a bank ATM, a convenience store kiosk terminal, a telephone, an Internet PC, a WEBTV or the like is used as a service access means. For all services that the user receives, the user must self-manage the personal authentication tool for each service provider, find the channel provided by the service provider, and access it. At present, issuing a unique account ID / password for each service company to the customer, for example, issuing an original IC card, is very costly, while individual users also receive an IC card for each service beneficiary company. It is very inconvenient to own and manage / set another account ID / password.

In order to solve such inconvenience, Japanese Patent Laid-Open No. 2001-147969 proposes to provide a common platform and issue and process a common IC card. However, the proposals disclosed here are
The file access keys of all the service providers are recorded and stored in the card. Even after the IC card is issued, each time a new service contract with each company is added, added, or changed, the IC card will be reissued for reissue. I have to go back and forth. This is an annoying and inconvenient task for both the service provider and the individual user.

[0005]

SUMMARY OF THE INVENTION The present invention is an easy-to-manage electronic card use authentication that can solve the above-mentioned inconvenience and annoyance for both the service providing company and the individual user of the above-mentioned conventional technology. The purpose is to provide a system.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a conceptual block diagram of an electronic card use authentication system showing an example of an embodiment of the present invention (Embodiment 1).

First, items which are prerequisites for constructing an electronic card use authentication system according to the present invention will be described. (1) Individual users choose to use the IC card issuer 1 that adopts the “common use mutual authentication center” 3. (2) The “Common Usage Mutual Authentication Center” 3 cooperates with some service companies 2. (3) An individual user (individual customer) uses the “common use mutual authentication center” 3 to register the service company 2 that receives the service.

There are the following cases when individual users register for services.

Here, the service companies participating in the "common use authentication center" are assumed to be company A, company B, and company C. For individual users, the differences between companies A, B, and C are as follows. Company A: We already have a transaction record and have obtained a customer ID / password. Company B: Transaction history but no customer ID / password. Company C: No transaction record. I want to start trading this time. <Case of Company A> -The customer himself / herself inputs the customer ID from the screen, whereby the customer ID is registered in the "common use authentication center". <Case of Company B> -Since the customer ID does not exist, the user himself cannot input the customer ID. From the screen, the “Common Usage Authentication Center” is instructed to additionally use the B company service. -Company B receives from the "Common Use Authentication Center",
The customer information database is searched based on the personal information (name / address / phone number) that has been authenticated, and the corresponding customer is verified. If the collation result is OK, the customer ID is generated and registered in the customer database.・ Customer ID is registered in "Common Usage Authentication Center" together with basic ID. <C company case> ・ Because there is no transaction record, use the personal authentication function of the "Common Use Authentication Center" to register as a member of the C company. -The user himself / herself will instruct the “Common Use Authentication Center” to apply for a new C company service from the screen.・ C company receives from "Common Use Authentication Center",
The customer information database is searched based on the personal information (name / address / phone number) that has been authenticated, and the corresponding customer is newly registered, and at the same time, the customer ID is also generated.・ Customer ID is registered in "Common Usage Authentication Center" together with basic ID. (4) Upon completion of all registrations (initial registration), the “common use mutual authentication center” 3 issues an electronic card such as an “IC card” 7 for authentication to the individual user. (5) When using the "IC card" 7, the user individually sets and registers an arbitrary usage password. (6) The individual user may access the access channel 15 (bank ATM, convenience store kiosk terminal, telephone,
In a mobile phone, Internet PC, WEB TV, etc., insert the "IC card" 7 and enter the password.

With this, the preparation for receiving the common tie-up service is completed.

Next, the configuration of this electronic card use authentication system will be described with reference to FIG. In this electronic card use authentication system, the IC card issuer 1 is provided with a basic ID of an individual housed in the IC card 7 and personal attribute information related to the basic ID (including a personal identification number determined by the customer). A computer system A11 is provided which has a database A111 in which is recorded, and which inputs, changes, refers to, and outputs the data. To service company 2,

In this way, the computer system A11 and each computer system B21 are connected to each other via the computer system C31 via a network such as online or the Internet.

The computer system A11 has a program A1 which receives the customer access information, collates the customer access information with the basic ID and the personal identification number of the customer access information with the database A111, and then transmits the same to the computer system C31. The computer system C31 is the computer system A1.
Upon receiving the customer access information from 1, the database C3
It has a program C1 that compares the basic ID recorded in 11 with the customer ID associated therewith and sends the customer access information to a computer system B21 having a database B211 in which the customer ID is recorded. The computer system B21 has a program B1 that receives the customer access information and executes the processing that is the content of the customer's request.

Further, each computer system B21
Has a program B2 for transmitting the addition of the customer ID of the database B211 to the computer system C31. The computer system C31 has a program C2 which receives this and associates it with the basic ID and registers it in the database C311. Here, the above-mentioned programs A1, B1, B2, C1, C2 are distributed and put in the program file of each computer system, but any program that fulfills the procedure of each program is sufficient. , Integrated or combined programs.
