Description

[0001] FINGERPRINT RECOGNITION CARD AND AUTHENTICATION METHOD USING THE SAME [0002]

The present invention relates to a fingerprint recognition card based on NFC communication and a payment method using the same.

Fingerprints are considered to be an important element to identify a person because of the fact that people have different fingerprints and that they do not change forever as they were when they were born.

According to the recent research, when the fingerprint is used as the authentication means, the problem of trespassing is least generated compared to other authentication means, the authentication means rarely causes an accident that is stolen, Which is significantly smaller than the authentication means.

In the conventional card, a user inputs a password of a card to an ATM or inputs a card unique number and an expiration date to authenticate the user. To use such a conventional card requires an expensive large-capacity host computer, and if the card is duplicated, lost, or the password of the card is exposed, the owner of the card would be economically damaged.

The fingerprint recognition card is a system that complements the data storage function, which is a disadvantage of existing credit card or debit card, and combines the advantages of IC (Integrated Circuit) card with the advantages of fingerprint security system. In order to solve the problems of the prior art, a payment system using such a fingerprint recognition card is being studied.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. It is to be understood, however, that the embodiments described below are only for explanation of the embodiments of the present invention so that those skilled in the art can easily carry out the invention, It does not mean anything. In describing various embodiments of the present invention, the same reference numerals are used for components having the same technical characteristics.

1 is a conceptual diagram illustrating an authentication system using a fingerprint recognition card 100 according to an embodiment of the present invention.

The fingerprint recognition card 100 may include a control unit 120, a memory unit 130, a communication unit 140, a power supply unit 160, a sensor unit 180, and a piezoelectric element 190 .

The control unit 120 stores the fingerprint recognized through the sensor unit 180 in the memory unit 130 and generates a unique identification value corresponding to the fingerprint. When the NFC terminal 200 is accessed, It is used to control the card, such as sending a value.

The memory unit 130 stores a unique identification value corresponding to the recognized user fingerprint through the sensor unit 180. [ When a plurality of users are recognized in one fingerprint recognition card 100, the memory unit 130 stores a plurality of identification values classified for each user.

The communication unit 140 may include an NFC module. The NFC module is formed to be able to exchange data with an adjacent NFC terminal 200. The communication unit 140 transmits the unique identification values of the users stored in the memory unit 130 to the NFC terminal 200 to perform user authentication.

The power supply unit 160 supplies power to each component of the fingerprint recognition card 100. The power supply unit 160 may include an embedded battery. The built-in battery is formed to be chargeable and can be charged by the electric energy generated by the piezoelectric element 190.

The sensor unit 180 has a fingerprint recognition sensor formed on one surface thereof, and can recognize the fingerprint of the user when the user touches the sensor unit 180. When the user fingerprint is recognized, the control unit 120 generates a unique identification value corresponding to each user's fingerprint, and the generated unique identification value is stored in the memory unit 130. [ The sensor unit 180 is formed so that it can be bent when the user touches the fingerprint recognition sensor.

The piezoelectric elements 190 are disposed so as to face each other and away from the power supply unit. The piezoelectric element 190 converts the physical deformation that occurs when the user touches the sensor unit 180 into electrical energy. In other words, when the user presses the sensor unit 180 to bend the fingerprint recognition sensor, the piezoelectric element 190 arranged to overlap with the sensor unit 180 receives pressure from the fingerprint recognition sensor. The pressure-receiving piezoelectric element 190 causes physical deformation and generates electrical energy.

When the fingerprint recognition card 100 accesses the NFC terminal 200, the communication unit 140 compares the unique identification value stored in the memory unit 130 with the unique identification value information stored in the server 300 If they match, the user authentication is completed. According to an embodiment of the present invention, when the initial user registration is performed through the fingerprint recognition card 100, only the unique identification value information of the first user is transmitted to the server 300, and the user's fingerprint or personal information is transmitted to the server 300, Lt; / RTI > That is, since the personal information is designed to be stored only in the owner's card and not to be transmitted to the server 300 or the database, the problem of leakage of personal information through hacking can be prevented in advance.

2 is a conceptual diagram illustrating a fingerprint recognition structure according to an embodiment of the present invention.

2, the fingerprint recognition structure includes a sensor unit 180 bending by a user's touch, a piezoelectric element 190 generating an electric energy under pressure from the sensor unit 180, a piezoelectric element 190, And a power supply unit 160 receiving energy generated from the power supply unit 160. [

A terminal 191 may be formed on one surface of the piezoelectric element 190. Likewise, the terminal 161 may be formed on one side of the power supply unit 160. When the sensor unit 180 is bent, the two terminals 161 and 191 come into contact with each other and current flows.

In other words, the recognition structure shown in Fig. 2 can serve as a pressure reducing switch. When the user presses the sensor unit 180 and the pressure is applied, the circuit is connected, power is supplied to the fingerprint recognition card 100, and when the user releases the hand and the pressure disappears, the circuit is opened and the power supply is interrupted. When the user presses the sensor unit 180 to apply pressure, electric energy is generated. At this moment, the circuit is connected to recognize the user's fingerprint. When the fingerprint recognition is completed and the user releases the hand, the circuit is cut off and the power is prevented from being wasted.

3 is a flowchart illustrating an initial user registration procedure according to an embodiment of the present invention.

Referring to FIG. 3, it is necessary to execute the fingerprint registration program in the NFC terminal 200 for the initial user registration. After the user executes the fingerprint registration program in the NFC terminal 200, the user brings the fingerprint recognition card 100 close to the terminal and recognizes the fingerprint on the card.

The fingerprint recognition card 100 receives a unique identification value generation command from the NFC terminal 200 and generates a unique identification value corresponding to the recognized fingerprint. The unique identification value can be encrypted and stored. The generated unique identification value is stored and stored in the memory unit 130 of the card.

The server 300 stores information corresponding to the generated unique identification value or unique identification value. The stored information is used as a basis for judging whether the unique identification value of the registered user is used when the user intends to authenticate using the card.

According to an embodiment of the present invention, one fingerprint recognition card 100 can be used by several users. For example, all of your family members can register and use it as a family card.

In this case, in order to register a multi-user, the NFC terminal 200 is caused to execute a user addition program. When the user addition program is executed, an instruction to recognize the fingerprint of the first registrant may be output. If the unique identification value of the first registrant is recognized, additional user registration procedures can be performed. A separate unique identification value corresponding to the fingerprint of the additional registrant is generated and stored in the card.

4 is a flowchart illustrating a user authentication method according to an embodiment of the present invention.

Referring to FIG. 4, the fingerprint recognition card 100 normally remains in a non-active state. When a fingerprint is detected due to pressure applied to the fingerprint sensor, the card goes into standby mode and power is supplied to verify fingerprints match.

When the registered user confirmation is completed through the stored unique identification value, the fingerprint recognition card 100 becomes an active mode and can perform operations such as user authentication or credit card settlement. When the fingerprint is separated from the fingerprint sensor after completion of the operation, the fingerprint sensor is switched to the non-active mode again.

When the fingerprint information discrepancy occurs, the fingerprint recognition card 100 remains in a standby mode and waits until a matching fingerprint is detected. However, if a matching fingerprint is not detected even after a certain response time has elapsed, the fingerprint reader is switched back to the non-active mode again.

If the fingerprint recognition sensor is pressed and the card is accessed to the NFC terminal 200, the user authentication process proceeds and if the fingerprint matches the information corresponding to the unique identification value stored in the server 300, The procedure is complete.

According to at least one embodiment of the present invention configured as described above, the fingerprint recognition card 100 is configured such that the fingerprint recognition sensor, the piezoelectric element 190, and the switch are organically coupled to efficiently transmit the electric energy generated when the user recognizes the fingerprint The card life can be increased.

In addition, according to the present invention, since the unique identification value corresponding to the fingerprint of the user is stored in the card without transmitting the user information to the server 300 at the time of user registration, leakage of the personal information can be prevented, Authentication can be performed.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
