In particular, the present invention relates to an authentication processing algorithm of a fused card that enables NFC module short-range wireless communication in cooperation with fingerprint recognition that can not be used unless human identity information is lost even if the authentication card is lost, will be.

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. The recognition rate of fingerprint recognition is known to be about 5%. For example, five out of 100 fingerprints can not be recognized.

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 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.

Therefore, since the decompression power source sensor 1509 is formed at a portion where the card is naturally pressed when the card is held in order to recognize the fingerprint, the decompression power source sensor 1509 is handled as a permanent material that can be easily used, Therefore, it is adopted as a power source for fingerprint recognition.

In addition, a temperature and / or blood flow sensor 1522 is formed on the fingerprint authentication module, which is a finger accommodating part, to activate the card controller 1501 by detecting the temperature of the finger or the blood flow when the finger contacts the finger, So that the scan unit 1502 can be operated.

These effects are as described above.

When the fingerprint data input from the scan unit 1502a and the fingerprint data stored in the card memory unit 1503 match, the card controller 1501 transmits the signal, that is, the card information, to the tag unit 1506, It is preferable to initialize the tag unit 1506 so that the card information is lost after using the card information by touching.

Alternatively, after the card controller 1501 records the card information in the tag unit 1506, the card controller 1501 holds the card information for 5 seconds, which is used for card approval, for example, and makes the tag unit 1506 available A method of initializing and losing card information is also desirable.

13, an IC chip 1506b and a solar cell panel 1507a of a power source unit 1507 are formed as a tag unit 1506 on the front surface of the authentication card 1500, as shown in Fig. 13, And a fingerprint authentication module 1600. The NFC tag 1506a may be formed as a tag portion 1506 on the back surface.

The fingerprint authentication module 1600 has a multilayer thin plate structure. A fingerprint registration layer 1620 is formed on the lower layer of the fingerprint authentication module 1600, a fingerprint recognition layer 1610 is formed on the upper layer thereof, The fingerprint 1600a is registered in the lower part thereof and is divided into layers in which the user can read and read the authentication, and it is a useful technique to utilize them to play a role as a security card.

As described above, according to the fusion authentication card using the fingerprint recognition according to the embodiment of the present invention, the fingerprint data is loaded on the authentication card itself, and if the user does not read the fingerprint on the card itself and read the fingerprint, In the case of performing the operations such as withdrawal of cash or payment of a card, it is possible to increase the security and reliability of card authenticity verification. In case of security, the false recognition rate of the fingerprint can be remarkably improved The authentication of the fingerprint and the blood flow detection sensor linked to the fingerprint can be concurrently authenticated, thereby reducing the error rate due to the forgery and alteration of the fingerprint and easily recognizing the human body information of the fingerprint with only one finger. There is an effect that can be eased.

15 is a flowchart illustrating a method of processing a fusion authentication card according to an embodiment of the present invention.

As shown in FIG. 15, first, in order to process the fusion authentication card according to an embodiment of the present invention, the blood flow state of the finger is detected whether the finger is placed on the finger receiving unit 1523 (S1500).

In the present embodiment, when blood flow of a finger is sensed through the blood flow sensor 1522 of the scan unit 1502 formed in the finger receiving unit 1523, the card controller 1501 Activate.

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 sensed at step S1500 and the card controller 1501 is activated, the card controller 1501 operates the fingerprint scan unit 1520 of the scan unit 1502 to irradiate the line of sight of the visible ray light source unit 1520a Or contacts the fingerprint authentication module with the fingerprint (S1510).

In step S1520, fingerprint data is inputted by scanning a finger through the fingerprint image sensor 1520b or the fingerprint authentication layer while touching the finger to the fingerprint authentication module or touching the fingerprint authentication module in step S1510.

After receiving the fingerprint data input from the user's finger in step S1520, the card controller 1501 compares the fingerprint data stored in the card memory unit 1503 with the fingerprint data stored in the card memory unit 1503 (S1530).

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

The card controller 1501 outputs the card information through the data output unit 1505 to thereby output the card information to the tag unit 1506. When the scan information of the finger of the user matches the information stored in the card memory unit 1503 in step S1530, Card information is recorded on at least one of the NFC tag 1506a and the IC chip 1506b (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.

At this time, if the card controller 1501 touches the authentication card 1500 once to use the card information, the card controller 1501 initializes the tag unit 1506 so that the card information is lost.

After the card controller 1501 initializes the tag unit 1506, the operation of the display unit 1504 is stopped so that the user can recognize the state in which the authentication card 1500 can not be used.

The following describes an invention in which two authentication modules are installed in an authentication card.

FIG. 16 is a block diagram illustrating a main configuration of a fusion authentication card according to another embodiment of the present invention. FIG. 17 is a configuration diagram specifically illustrating a scanning unit of a fusion authentication card according to another embodiment of the present invention. FIG. 18 is a flowchart illustrating a method of processing a fusion authentication card according to an embodiment of the present invention. Referring to FIG.

8, except that the fingerprint scanning unit 1521 is formed in addition to the fingerprint scapper unit 1520. The fingerprint scanning unit 1521 may be a fingerprint scanning unit.

16, the authentication card 1500 includes two fingerprint scanning units 1520 and 1521 for generating and outputting fingerprint data by a finger of a person, A scan unit 1502 including a blood flow sensor 1522 for activating the card controller 1501 through a blood stream recognizing the flow is formed and the fingerprint data is read from the scan unit 1502 and stored in the card memory unit 1503, And a tag unit 1506 such as an NFC tag 1506a or an IC chip 1506b for outputting a signal output from the card controller 1501. The tag controller 1501 determines whether the fingerprint data matches the fingerprint data stored in the tag memory 1506, And a data output unit 1505 for recording the data on the display unit 1504. The display unit 1504 is provided to indicate whether or not the operation is performed.

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 .

A solar cell panel 1507a or a reduced voltage power source sensor 1509 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.

Alternatively, after the card controller 1501 records the card information in the tag unit 1506, the card controller 1501 holds the card information for 5 seconds, which is used for card approval, for example, and makes the tag unit 1506 available A method of initializing and losing card information is also desirable.

As shown in Fig. 17, Fig. 17 is a perspective view of the fusion authentication card of the present invention, showing positions where two fingers are to be held, and the shape of a fingerprint is shown on the top.

A decompressed power source sensor 1509 used here is formed by laminating a polymer conductor film on the ground of a thin film and alternately arranging a negative electrode and a positive electrode in the form of a comb in the surface of another film opposite to the base plate, And a pressure sensitive resistance variable sensor element made of tungsten oxide powder are layered and pressed against the polymer conductive film to detect a change in resistance to pressure and transmit the electrical signal.

As shown in FIG. 18, FIG. 18 is a flowchart illustrating a method of processing a fusion authentication card according to an embodiment of the present invention.

In order to process the fusion authentication card according to an embodiment of the present invention, first, the blood flow state of the finger is detected whether the finger is placed on the finger receiving unit 1523 (S1500).

In the present embodiment, when blood flow of a finger is sensed through the blood flow sensor 1522 of the scan unit 1502 formed in the finger receiving unit 1523, the card controller 1501 Activate.

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).

After receiving the fingerprint data input from the user's finger in step S1520, the card controller 1501 compares the fingerprint data stored in the card memory unit 1503 with the fingerprint data stored in the card memory unit 1503 (S1530).

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.

At this time, if the card controller 1501 touches the authentication card 1500 once to use the card information, the card controller 1501 initializes the tag unit 1506 so that the card information is lost.

After the card controller 1501 initializes the tag unit 1506, the operation of the display unit 1504 is stopped so that the user can recognize the state in which the authentication card 1500 can not be used.

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.

As described above, according to the method for processing a fusion authentication card using fingerprint recognition according to the embodiment of the present invention, the fingerprint data is loaded on the authentication card itself, and after the user's fingerprint is read from the card itself and read , It is possible to increase the security and reliability of the authenticity check of the card user in performing operations such as withdrawal of cash or payment of a card by making it impossible to use the card. It is possible to reduce the false recognition rate of the fingerprint and to easily recognize the human body information of the fingerprint with only one finger by using the blood flow detection sensor which can improve the effect of the security that can replace the authorized certificate have.

When the fingerprint data input from the scan unit 1502 and the fingerprint data stored in the card memory unit 1503 match, the card controller 1501 transmits the signal, that is, the card information, to the tag unit 1506, It is preferable to initialize the tag unit 1506 so that the card information is lost after using the card information by touching.

Alternatively, after the card controller 1501 records the card information in the tag unit 1506, the card controller 1501 holds the card information for 5 seconds, which is used for card approval, for example, and makes the tag unit 1506 available A method of initializing and losing card information is also desirable.

As shown in FIG. 21, in order to process the fusion authentication card according to an embodiment of the present invention, the power source 1703 is first turned on (S1700).

When the power is turned on, it is first determined whether the fingerprint, the photograph, and the basic information unique to the smart card formed in the smart chip are registered (S1700a).

If the information is not registered, the fingerprint or proof photograph is scanned and registered in the card memory unit 1720 formed with a smart chip or basic information such as a resident registration number (name, corporation name, etc.) is registered (S1710).

If desired information is registered in the card memory unit formed with the smart chip, the process ends.

As a next step, when the information is registered, the credit card is operated by using the credit card.

In this case, although the step of registering the various kinds of information and the authentication step of determining whether the fingerprint is matched to the next step are successively displayed, they must be separated into a separate registration step and a separate information coincidence determination step. And a fingerprint that is an authentication procedure while the power is supplied by a pressure sensor (or a solar battery or a battery) at the time of use.

After enabling the use of the authentication card 1500, the card controller 1501 compares whether the set time has elapsed (S1750).

If, for example, 5 seconds (or 10 seconds) elapses in step S1750, the card controller 1501 initializes the tag unit 1506 and transmits the NFC tag 1506a and the IC chip 1506b The recorded card information is lost so that the use of the authentication card 1500 is disabled.

At this time, if the card controller 1501 touches the authentication card 1500 once to use the card information, the card controller 1501 initializes the tag unit 1506 so that the card information is lost.

After the card controller 1501 initializes the tag unit 1506, the operation of the liquid crystal display unit 1508 is stopped so that the user can recognize the disabled state of the authentication card 1500.
