Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a user authentication system and an authentication method, and more particularly to a user authentication system and an authentication method using biological information such as a user's fingerprint, iris, shape, and voice in a network environment.

[0002]

2. Description of the Related Art In recent years, various online services using the Internet have been put to practical use.
Among such various application fields, in particular, about the purchase and usage fee of information such as articles such as newspapers and magazines, real estate information, papers, etc., and how to pay for purchased goods via the Internet,
In particular, research and development are being actively pursued with regard to safety issues.

[0003] According to the conventional settlement method, after the user places an order for goods and confirms the amount of goods via the Internet,
A method has been used in which an article price is passed through a non-passbook and the payment is confirmed. Alternatively, a credit card number is input online through a security server, and a settlement method based on the input number is used. In recent years, with the introduction of the concept of electronic money, a method has been used in which a fixed amount of electronic money is purchased in advance and the amount of the money is settled, and a payment method using a prepayment card is also used.

[0004]

However, in such a payment method using a credit card, a credit card number or a reciting number must be entered. In this inputting process, information such as a card number and a validity period is lost. There is a possibility that the information is leaked, and such a loss of information develops into a problem of card forgery. There is a problem that another person may use this forgery card, and security in using the card becomes a problem.

On the other hand, in places where security is required, such as homes, businesses, buildings, etc., various lock devices and user authentication devices have been developed and used to prevent intrusion from outside, in addition to such electronic settlement. . However, since most of such lock devices use the password input method, there is a risk that the password is leaked. As a result, it is difficult to use in places requiring security, and there is a disadvantage that a security request must be separately made to an external company.

In order to solve such a problem, US Pat. No. 5,280,527 proposes a method for accessing a system using a token or card storing biometric information. I have. However, such an authentication method is merely a user authentication system based on a single piece of biometrics information, and there is a possibility that a token or a card may be lost. There was a problem that it was difficult to use it as a perfect security system due to the inconvenience of updating the system.

[0007] The present invention has been made to fundamentally solve the above-mentioned problems.
An object of the present invention is to enable user authentication with excellent security in electronic commerce or a building and home security system.

[0008] Another object of the present invention is to perform user authentication using at least one or more pieces of biometric information, thereby reducing errors according to the biometric information and enabling accurate user authentication.

Yet another object of the present invention is to make it possible to easily update and store changing biological information,
The purpose is to always provide accurate use authentication.

[0010]

In order to achieve the above object, the present invention provides a biometric information acquisition system for obtaining biometric information such as a user's fingerprint, iris, shape, and voice; A transmission means for transmitting; a user authentication unit for performing user authentication by comparing the transmission information from the transmission means with the stored biometric information database; and data relating to biometric information of a user who can be authenticated and access rights for each user. And a biological information database having information.

A user authentication method using such a system includes a step of inputting at least one or more pieces of biological information; a step of transmitting the input biological information; and a step of transmitting the input biological information and the recorded biological information. Comparing; and performing a user authentication based on the comparison value.

[0012] The user authentication method may include a step of comparing the transmitted biometric information with the recorded biometric information and storing a comparison value.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a diagram showing a system for obtaining biological information of a user.

As shown in FIG. 1, the system for obtaining the biological information of the user includes a user's fingerprint, iris, shape,
It is characterized by having an input unit 10 for obtaining information such as voice, and a conversion unit 20 for converting the biological information of the user input by the input unit into data in a form that can be transmitted.

The input unit 10 includes a voice information detecting module 1 for inputting a user's voice, a fingerprint detecting sensor for detecting a fingerprint based on a charge distribution or a pressure difference of the fingerprint, or a fingerprint including a camera for detecting a fingerprint pattern. The information sensing module 2 may be an iris information sensing module 3 including a camera for sensing an image pattern of the iris.

The conversion unit 20 converts the biometric information obtained by the voice recognition module, the fingerprint information sensing module, the iris information sensing module, and the like into data that can be transmitted, or compresses the data, if necessary. It plays a role, and can be an application that can be mounted on a computer or the like and that can be executed independently.

The transmission means 30 is preferably included in the system, but plays a role of transmitting data by a method such as parallel communication, serial communication, or infrared communication. In the case of a computer, it can be a communication means such as a network card or a modem.

The biometric information database 40 has a user's name, information necessary for user authentication, and information on the biometric information of the user. Further, the biometric information database may selectively include a biometric information update database 41 that stores transmitted biometric information and tracks and updates the degree of change for tracking the trajectory of changing biometric information. .

The user authentication section 50 authenticates the user by comparing the biological information transmitted from the network transmission section with a biological information database.

FIG. 2 is a process diagram of performing user authentication through the user authentication system according to the present invention. When the user requires authentication, at least one or more of his or her biometric information, for example, input an iris or fingerprint, and the input data such as the iris or fingerprint is transmitted to the server through the network, If the user matches the stored biometric information after comparing with the existing biometric information, the user is authenticated as a valid user.

[0021]

According to the present invention, the use of unique personal biometric information for user authentication can significantly increase the accuracy of authentication, and perform user authentication without using a separate keyword or ID code. be able to. Therefore, the security of the personal authentication can be improved without the keyword or ID code being stolen by another person. In addition, since there is no need to set a keyword or an ID code or to store the keyword or the ID code, the convenience of the user in the authentication system can be improved.
