Description

[0001] CERTIFICATION CARD CHECKING FINGERPRINT [0002]

The present invention relates to a wireless rechargeable authentication card interlocked with fingerprint recognition. And more particularly to a wireless rechargeable authentication card that is interlocked with fingerprint recognition that can not be used unless the user's personal information is lost even if the authentication card is lost.

It is a point of biometric authentication technology applied to a fusion authentication card using fingerprint and finger vein recognition, that is, authentication of a person by acquiring biometric information unique to each person using a cash payment card and recognizing it.

In the case of fingerprint recognition, there is a problem that the front of the fingerprint can be easily forged and copied. In addition, frequent authentication errors were pointed out, such as when moisture or foreign matter is present on the finger or when the finger skin is damaged or deformed.

On the other hand, the irregularity recognition technology has pointed out the error problem by distance and angle. In addition, there was a problem that the subject failed authentication when wearing a color content lens or undergoing LASIK or LASIK surgery. Especially, the time required for authentication was long.

The NFC (Near Field Communication) method is activated by being applied to a smart phone because it is advantageous for security because of non-contact short distance communication. NFC communication is performed wirelessly between an NFC reader and an NFC tag, And a loop antenna (Loop Antenna).

The NFC technique includes a component including a communication interface operating as an inductive coupling and has two or more operation modes including a reader mode and a card emulation mode.

The NFC communication unit performs short-range data communication to perform an RFID reader function and / or a tag function in the outside, for example, in the 13.56 MHz band.

Also, as a method of decrypting a magnet (hereinafter referred to as MGT) card, a magnet card having a magnet has three magnet tracks on a magnet strip. A magnetic flux is streaked in the magnet track segment. The interval between magnetic fluxes changes according to binary information (binary information) 0 or 1. The magnetic fluxes which are successive to each other are then operated with corresponding magnetization directions.

Fingerprint authentication technology is superior to biometrics technology in that it provides superior biometric information in all aspects, such as inferiority composition, false acceptance rate, false rejection rate, failure to enroll rate, It was announced.

The finger vein authentication technique is a technique of recognizing a vein pattern by transmitting a near infrared ray to a finger. Because it authenticates the inside of a blood vessel, it can not be tampered with, and there is also an advantage that a finger vein pattern of a dead person can not be utilized.

This fingerprint authentication technology combines a hardware device technology for obtaining a finger vein image using a CCD camera and a software technique for filtering a finger vein image using a pattern processing program or extracting vein patterns .

Generally, as a method of checking the authenticity of a card user in using a cash card and a credit card, there is a method of inputting a password in the process of using the card, so that the input password is matched with the password stored in the bank. We confirmed the authenticity of the card user.

However, the conventional card user's intention confirmation method as described above can not be used by any other person by using a lost card or a duplicated card, or by taking a card in a coercive way to the owner of the card, But could not control it at its source.

Hence, in the past, a card payment method by fingerprint recognition using a fingerprint and the card have been developed.

Japanese Patent Laid-Open Publication No. 2002-0052021 discloses a fingerprint recognition device for generating and outputting data by pressure light emission on a card, thereby greatly improving the reliability and security of the user's authenticity check in the process of using the card It was invented.

That is, in the related art, a fingerprint recognition device that reads fingerprint data by a pressure light emitting method on a card and generates and outputs fingerprint data is provided to improve the security and reliability of authenticity verification of a card user. The user information such as the user's fingerprint data and the user's personal data input by the fingerprint input and inputs the inputted user information to the main data portion 3 of the management system 2, A card issuing step (100) of issuing identification data to the card memory (13) and issuing the card (10); A card inserting process 210 for inserting the fingerprint recognition device 12 of the card 10 issued through the card issuing process 100 and inserting the card 10 into the card using equipment 1; A card recognition process (220) for reading the inserted card (10) through the card insertion process (210); A password confirmation process 230 for receiving the password of the card 10 from the user and confirming whether the password is matched; A genuine confirmation data input confirming process 240 for determining whether genuine confirmation data is inputted from the card 10 through the fingerprint authenticity checking process of the card 10 when the password is identical through the password checking process 230, A work item input step (250) of receiving a work item from a user when a signal input is confirmed through a confirmation data input checking step (240); A work execution decision step (260) for determining whether or not the work items inputted through the work item input step (250) are implemented; A task execution process (270) for performing a task when it is judged to be executable through the task execution determination process (260); And a card discharging process 280 for discharging the input card 10 after the completion of the job performing process 270.

Here, the fingerprint verifying process of the card 10 includes a fingerprint data generating and outputting process 310 in which the fingerprint recognizing device 12 outputs fingerprint data by pressing the fingerprint recognizing device 12 when the user inserts the fingerprint recognizing device 12 ; A fingerprint authenticity determination process 320 for comparing fingerprint data input through the fingerprint data generation and output process 310 with fingerprint data stored in the card memory unit 13 to determine whether the fingerprint data is genuine; An intrinsic confirmation data output step (330) for outputting intrinsic confirmation data to the card-using device (1) and the fingerprint recognition device (12) when the intrinsic property is determined through the fingerprint intrinsic property determination process (320); A fingerprint recognition device reset process 340 for resetting the fingerprint recognition device 12 that has been lighted in response to the input signal in accordance with the determination result of the authenticity confirmation data output process 330 and the fingerprint authenticity determination process 320 will be.

Reference numeral 15 denotes a magnetic part used in a typical card.

As described above, the card 10 capable of recognizing a fingerprint includes a fingerprint recognition device 12 for generating and outputting fingerprint data by pressure light emission, a fingerprint reading device 12 for reading a fingerprint from the fingerprint recognition device 12, And a data output unit 14 for outputting the signal output from the card controller 11 to the card using equipment 1 .

However, the above-mentioned card payment method by fingerprint recognition and a technique relating to the card include a fingerprint recognition device for generating and outputting fingerprint data by pressing light on the card, so that the authenticity check operation of the card user is reliable, It is possible to confirm the authenticity of the card user in the card using equipment 1 without using a separate identification device because the card using equipment 1 is used. It is advantageous that convenience is improved even if the fingerprint recognition is not carried out in the process of authenticating the fingerprint. However, if the fingerprint authentication device 1 is not installed, Even if the pattern is embedded, the card could not be used, and a separate system must be developed to utilize it Next, a situation that its technology is the boss.

In addition, there was a problem that the fingerprint authentication could not cover the possibility of false recognition and the false recognition rate of only one fingerprint.

The IC card has important information such as a user's private key, personal information, and main code, and is used in many applications due to its high security compared to a conventional magnetic tape card.

Further, the IC card is divided into a contact type card which is driven by receiving power from a card reader, and a non-contact type card which is supplied with power by using an electromagnetic induction principle. These IC cards commonly have a common point that power is externally applied to drive an internal circuit of a card.

In addition, the passive hacking operation of the IC card is performed by driving the internal circuit while power is externally applied to the card system, Or analyzing the response time of the operation.

As an alternative to such a hacking method, a method of preventing passive hacking by using a card system having a built-in battery has recently been proposed.

[0004] However, only a minute current is required to drive the IC chip circuit of the card. However, a phenomenon that a larger amount of current is required when displaying a fingerprint image or a self-authentication image mounted on the card, It was a situation that was hard to afford alone.

Therefore, a method of supplying power to the IC card from the outside or a method of accumulating power at a normal time is more efficient.

In addition, in the case of fingerprint recognition and facial photographing applied in the present invention, there is a problem that much more power is required to operate than in the case of a commonly used IC card.

It is an object of the present invention to provide a method of charging an external power source rather than a battery because power is supplied to the IC card even when power is supplied to the IC card, It has its purpose.

It is also an object of the present invention to provide a fingerprint authentication system which is capable of loading fingerprint data on an authentication card itself and making it impossible to use the authentication card itself after blood flow detection is performed at the time of fingerprint recognition by a user, It is possible to enhance the security and authenticity of card authenticity verification of the card user, and the purpose of fingerprint recognition itself is to pursue accuracy and simplicity. That is, it is an object of the present invention to provide an authentication system which prevents authentication of temperature and / or blood flow due to forgery or alteration of silicon or the like.

Furthermore, since there is a problem in that the power supply for use of the NFC of the authentication card or the power supply for using the IC chip can not be used for a long time in the case of a general battery, the fingerprint authentication card based on the wireless charging method is considered, And the design of the authentication card can be simplified.

8, the authentication card 1500 includes a fingerprint scanning unit 1520 for generating and outputting fingerprint data by a finger of a person, a blood flow sensor for detecting a flow of the blood flow of the finger of the customer, A scan unit 1502 including a blood flow sensor 1522 for activating the card controller 1501 through the scan unit 1502 is formed and the fingerprint data is read from the scan unit 1502 to check the authenticity stored in the card memory unit 1503 And a data output unit 1506 for writing a signal output from the card controller 1501 to a tag unit 1506 such as an NFC tag 1506a or an IC chip 1506b, And a display portion 1504 for displaying whether the display portion 1504 is operated or not.

Here, the fingerprint data stored in the card memory unit 1503 stores the fingerprint data obtained by scanning the fingerprint through a scanning device (not shown) separately provided to the financial institution and the card issuing organization when the authentication card 1500 is initially issued .

The solar panel 1507a is formed on the front surface of the authentication card 1500 as a power source unit 1507 for generating and storing a power source for operating the authentication card 1500. [

The card controller 1501 transmits the signal to be written to the tag unit 1506, that is, the card information, when the data inputted from the scanning unit 1502 and the fingerprint data stored in the card memory unit 1503 are identical, It is preferable to initialize the tag unit 1506 so that the card information is lost after using the card information by touching.

9, an IC chip 1506b and a solar cell panel 1507a of a power source unit 1507 are mounted on the front surface of the authentication card 1500 with a tag unit 1506, And an NFC tag 1506a may be formed as a tag unit 1506 on the back surface as shown in FIG.

11, the scan unit 1502 is provided with a finger receiving unit 1523 for placing a finger to scan the fingerprint on the front surface of the authentication card 1500, (1502) are formed. At this time, it is preferable that the finger receiving portion 1523 is formed of a transparent material through which infrared rays and visible rays of the fingerprint scanning portion 1520 can be transmitted.

The fingerprint scanning unit 1520 forms a line-of-sight light source unit 1520a and a fingerprint image sensor 1520b for photographing the fingerprint of the finger on the edge of the finger receiving unit 1523. [ At this time, the visible ray light source unit 1520a may be inclined toward the contact surface where the finger is in contact with the authentication card 1500 so that the visual line may be irradiated to the entire fingerprint of the finger, A reflection member 1520c for reflecting the finger contact surface to the fingerprint image sensor 1520b at the lower part of the contact surface of the fingerprint image sensor 1520b may be formed to increase the degree of positional freedom of the fingerprint image sensor 1520b.

Therefore, even if the fingerprint image sensor 1520b is formed at the edge, the finger contact surface is reflected through the reflection member 1520c, so that the fingerprint of the finger can be photographed. At this time, the reflecting member 1520c may be formed as a flat surface or a curved surface depending on the installation environment.

In addition, the line-of-sight light source unit 1520a and the fingerprint image sensor 1520b of the fingerprint scan unit 1520 may be formed in pairs at opposite positions or may have a plurality of line-of-sight light sources 1520a.

In addition, a blood flow sensor 1522 is formed in the finger receiving portion 1523 to sense the flow of blood of the finger when the finger contacts the finger, thereby activating the card controller 1501, 1502 may be activated.

Although the blood flow sensor has one point in the drawing, one authentication layer 1611 can be formed by using one layer of the fingerprint authentication module 1600 to authenticate the temperature and / or blood flow of a person.

That is, even if the power is turned off in the standby state, the card controller 1501 can be activated by the bioelectricity generated when the finger contacts the finger receiving portion 1523, so that the standby power can be reduced and the standby power load can be reduced The size of the solar cell panel 1507a and the storage battery (not shown) of the power source unit 1507 can be reduced, thereby improving space utilization.

The fusion authentication card according to the present embodiment is configured such that when a user places a finger on the finger receiving portion 1523 of the authentication card 1500, the human body temperature of the scan portion 1502 and / or the temperature of the card controller 1501 ). The card controller 1501 thus activated activates the fingerprint scan unit 1520 of the scan unit 1502 to irradiate the finger placed on the finger receiving unit 1523 with the line of sight through the line of sight light source unit 1520a, 1520b to receive the fingerprint data.

The human body temperature and the blood flow can be distinguished. However, in the case of recognizing the temperature, the human body can be automatically recognized as normal and processed as long as the blood flow of the human body flows through one sensor.

When the fingerprint data of the finger is inputted, the card controller 1501 compares the fingerprint data of the user stored in the card memory unit 1503 and, if they match, transmits the card information to the tag unit 1506 through the data output unit 1505, Tag 1506a and the IC chip 1506b so that the authentication card 1500 can be used for payment or the like.

If the blood flow of the finger is not detected in step S1500, the card controller 1501 is not activated and remains in the standby state continuously.

On the other hand, if the blood flow of the finger is detected in step S1500 and the card controller 1501 is activated, the card controller 1501 operates the fingerprint scan units 1520 and 1521 corresponding to the fingerprints 1 and 2 of the scan unit 1502, The fingerprint is contacted to the authentication module 1600a (1600b) (S1510).

In step S1520, fingerprints are scanned through the respective fingerprint image sensors while the fingerprint is being contacted to the fingerprint authentication module 1600a (1600b), and the fingerprint data is received (S1520).

Here, the card controller 1501 compares the inputted fingerprint data with the fingerprint data of the user stored in the card memory unit 1503.

If the scan information scanned by the user's finger is identical to the fingerprint 1 information stored in the card memory unit 1503 in step S1530, the scan information scanned by the finger of the user in step S1535 is stored in the card memory unit 1503 The card controller 1501 outputs the card information through the data output unit 1505 to at least one of the NFC tag 1506a and the IC chip 1506b of the tag unit 1506, Information is recorded (S1540).

When the card information is normally recorded in the tag unit 1506, the card controller 1501 activates the display unit 1504 so that the user can recognize that the authentication card can be normally used (S1550).

In a state where the use of the authentication card 1500 is enabled in step S1550, the authentication card 1500 may be provided to another person for payment such as clerk. After enabling the use of the authentication card 1500, the card controller 1501 compares whether the set time has elapsed (S1560).

If, for example, five seconds have elapsed in step S1560, the card controller 1501 initializes the tag unit 1506 so that the card information recorded in the NFC tag 1506a and the IC chip 1506b is lost So that the use of the authentication card 1500 is disabled.

When an authentication card is produced using the two modules as described above, there may be an error in the degree of fingerprint recognition during the production process. If the probability of imitation of the fingerprint is lowered by using only one of the two modules, When the angle of adhesion is different at the time of authentication, the degree of recognition is lowered. In the case of designing a match of 100%, recognition of a part of a finger is difficult due to water or ink, etc. Therefore, if the two fingerprints are authenticated at the same time while the degree of matching is reduced to about 60%, and the operation signal of the card can be generated, the design of the mechanical recognition technology is facilitated, and the state .

That is, if the probability of error of one fingerprint is one hundred thousandths, it is lowered to 80% of recognition, and if two modules are used simultaneously to satisfy the condition of being satisfied, As the results show, there is a probability of covering the global population, and consequently there is no realistically the same two fingerprints.

In addition, when the finger is grounded with two fingers, a recognition structure of the fingerprint can be stably and uniformly grounded, thereby increasing the recognition degree.
