Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that in individual authentication using collation of biological features, it takes a long time to output a collation result depending on the size of an object to be collated for the collation of biological features. <P>SOLUTION: The object to be collated for collation of biological features is reduced in size in advance by use of the position of a radio portable terminal before authentication in settlement or the like is required.

Description

The present invention is a technique for reducing the time spent for authentication work for personal authentication by collating biometric information, and a technique for adjusting the response time of a personal authentication system by collating biometric information.

A network having wireless equipment such as a cellular phone service has position information of a wireless terminal by using information on a communication state based on the strength of radio waves between the wireless terminal and the wireless base station. The position information is identified as a specific range on the earth.

A user of a wireless terminal is usually an individual who has the right to use the wireless terminal, and personal information such as the user's address is registered at the time of contract.

As a method for identifying and authenticating an individual, there is personal authentication by collating biometric information.

There is no correlation between the position information of the wireless terminal and personal authentication based on biometric information verification.

An individual having a specific biometric feature can be identified with high probability by the individual identification method based on biometric feature matching. However, depending on the size of the target matrix for matching biometric features, it may take a long time to output the matching result, and the length of time until the authentication is a company or group that benefits from personal authentication. In most cases, it is a disadvantage to the individual, such as loss of opportunity.

The location information of the wireless terminal is directly or is converted into predefined location identification information from a wireless network such as a cellular phone service, and distributed to a personal authentication system managed by a biometric personal authentication service provider.

Based on the distributed position information, the personal authentication system using biometric information collation reduces the biometric information collation target matrix. Since this operation is automatically performed according to a change in the wireless terminal position information, the reduction of the biometric information verification target matrix has already been completed at the time of personal authentication by biometric information verification in a store or the like.

When performing personal authentication by collating biometric information, there is a possibility that biometric information is collated as it is from the above-mentioned reduced collation target parent, or only the authentication target individual such as a password is known before that By inputting high information, the verification target matrix is further reduced and biometric information verification is performed.

In the biometric information collation method, the biometric information data itself is a collation target, or a CRC (Cyclic Redundancy Check) value of the data is calculated, and the CRC value is the collation target.

The present invention is based on the fact that the biometric information verification target matrix used for personal authentication by biometric information verification is reduced based on the wireless terminal position information in advance regardless of the authentication request for personal authentication. This contributes to shortening the time required for personal authentication when requesting authentication. In addition, due to time savings, personal information can be used to refer to information such as affiliation to the organization and the right to receive services without presenting a membership card to a specific organization or service. it can.

Embodiments of the present invention will be described with reference to the drawings.

In realizing this patent, function groups F0000 to F0007 in FIG. 1 are defined.
However, the configuration and function are logically defined, and their physical arrangement and number depend on the realization environment.

F0000: Wireless communication network overview The network described in the wireless communication network overview holds location information of wireless terminals.

Further, an area identifier is extracted from the wireless terminal position information with reference to the area database. Thereafter, a terminal identifier and an area identifier are transmitted to the corresponding F0003: personal information storage server (hereinafter referred to as a personal information copy request).

F0003: Personal information storage server This function receives and stores personal information including biometric feature data from the F0006: personal information and area management server described later (hereinafter referred to as a personal information database). Further, F0004, which will be described later associated with the area identifier: a database of identifiers of the biometric personal authentication server (hereinafter referred to as biometric personal authentication server database) and the radio terminal associated with the radio terminal identifier. It has a database (hereinafter referred to as the current area database) of existing areas (hereinafter referred to as the current area).
