Description

Technical Field

[0001] The present invention relates to a power supply film and a method for registering a user's fingerprint on a fingerprint recognition card using the power supply film.

Background Art

[0002] Generally, a fingerprint recognition card is equipped with a fingerprint recognition sensor on the card so that a user's fingerprint can be registered and used.

[0003] However, since the power required to save and register a user's fingerprint on the fingerprint recognition card is not provided by the fingerprint recognition card itself, it is possible to receive the input of fingerprint information via a card reader device.

[0004] In recent years, a type has been developed in which a battery is built into the fingerprint recognition card to supply the power required for fingerprint recognition and registration. However, when a battery is built into the fingerprint recognition card, problems such as failure or deformation may occur due to the battery life during long-term use, and the durability as a fingerprint recognition card may decrease.

Summary of the Invention

Problems to be Solved by the Invention

[0005] Normally, in order to register a user's fingerprint on a fingerprint recognition card, a PC (Personal Computer), a registration program, and a registration terminal must be provided. However, the present invention provides a power supply film that can be attached with a disposable power supply film without such equipment and can receive the power required for registering a user's fingerprint into the fingerprint recognition card and process it, and a method for registering a user's fingerprint on a fingerprint recognition card using the power supply film.

Means for Solving the Problems

[0006] According to one aspect of the present invention for achieving the above objective, a power supply film is provided which adheres to a fingerprint recognition card and supplies power to the fingerprint recognition card, wherein the power supply film includes a paper battery that supplies power.

[0007] Furthermore, according to another aspect of the present invention, a method for registering a user's fingerprint for a fingerprint recognition card is provided, comprising: a first step of removing a protective film from a power supply film; a second step of attaching the power supply film to one side of a fingerprint recognition card after the first step so that power from a paper battery in the power supply film is supplied to the fingerprint recognition card; a third step of supplying power to a CPU in the power supply film after the second step; a fourth step of the CPU transmitting a command signal for registering the user's fingerprint by the fingerprint recognition card to the security CPU of the fingerprint recognition card after the third step; and a fifth step of the security CPU in the fingerprint recognition card extracting the user's fingerprint template after the user's fingerprint is input to the fingerprint recognition sensor of the fingerprint recognition card. [Effects of the Invention]

[0008] As described above, the present invention is a disposable power supply film equipped with a paper battery. When the power supply film is attached to and connected to a fingerprint recognition card when a user registers their fingerprint on the fingerprint recognition card, the power from the paper battery is supplied to the fingerprint recognition card and can be used as power when registering the user's fingerprint via the fingerprint recognition sensor on the fingerprint recognition card.

[0009] Furthermore, the present invention allows for the separation and removal of the attached power supply film once the user's fingerprint registration on the fingerprint recognition card is complete.

[0010] This invention provides a disposable power supply film in sticker form, which is attached to a fingerprint recognition card to provide the power necessary to register the user's fingerprint in the memory section of the fingerprint recognition card. As a result, the fingerprint recognition card does not have a separate battery built in, allowing it to be used semi-permanently.

[0011] Therefore, a fingerprint recognition card on which a user's fingerprint has been registered based on a fingerprint registration method according to one embodiment of the present invention can be used as an entry / exit control means or as an authentication means for various purposes, such as when settling card payments.

[Figure 8] This figure shows a second embodiment of the fingerprint recognition card of the present invention. [Figure 9] This figure shows a third embodiment of the fingerprint recognition card of the present invention. [Modes for carrying out the invention]

[0013] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the technical idea of the present invention is not limited to the described embodiments, can be realized in various forms, and within the scope of the technical idea of the present invention, at least one of the components between the embodiments can be selectively combined and / or replaced.

[0014] According to an embodiment of the present invention, in order to perform the fingerprint registration method of the fingerprint recognition card according to the present invention, it can include a fingerprint recognition card 100 and a power supply film 200 that can be attached to supply power to the fingerprint recognition card 100.

[0015] Here, the power supply film 200 attached to the fingerprint recognition card 100 can be provided in the form of a sticker. Therefore, after being attached to the fingerprint recognition card 100, when the user's fingerprint registration procedure is completed, it can be separated again and removed from the fingerprint recognition card 100.

[0016] A protective film can be provided on one side of the power supply film 200. When the protective film is separated, the adhesive component is exposed and can be detachably attached to the fingerprint recognition card 100.

[0017] In other words, the power supply film 200 can be attached to the fingerprint recognition card 100 for disposable use, supply the power required for fingerprint registration, and then be removed when the fingerprint registration is completed.

[0018] Contact terminals can be provided on the fingerprint recognition card 100 and the power supply film 200 so that the power of the power supply film 200 is provided to the fingerprint recognition card 100. Each contact terminal can be in a state of being connected to an IC card connector 130 and an IC connector 240 provided on the fingerprint recognition card 100 and the power supply film 200, respectively.

[0019] The power supply film 200 can include a paper battery 210, a current sensor 220, a CPU 230, and an IC connector 240.

[0020] The paper battery 210 does not mean a battery made of paper, but can mean a battery that is as thin and flexible as paper.

[0021] The paper battery 210 can supply power to the CPU 230 so that operations can be performed.

[0022] At this time, the current sensor 220 can prevent the power of the paper battery 210 from continuously being supplied to the CPU 230 and prevent the current from being wasted during the standby state. When the power supply film 200 adheres to the fingerprint recognition card 100, the power supply from the paper battery 210 to the CPU 230 can be performed by the output signal output while the current sensor 220 is activated.

[0023] The current sensor 220 can output an output signal of 0V to the working voltage (3.3V, 5V). It can be 0V when no current is flowing and the working voltage when current is flowing.

[0024] The current sensor 220 can be composed of a shunt resistor and a non-inverting amplifier OP-Amp.

[0025] When the power supply film 200 is attached to the fingerprint recognition card 100, a signal is output while the current sensor 220 is activated, and the power of the paper battery 210 can be supplied to the CPU 230 using this signal so that the CPU 230 can be in an operable state.

[0026] When the power supply film 200 is attached to the fingerprint recognition card 100, the CPU 230 detects the current from the paper battery 210 via the current sensor 220 and operates accordingly, allowing it to control the supply of power from the paper battery 210 to the fingerprint recognition card 100.

[0027] The fingerprint recognition card 100 may include an antenna 110 and a controller 120 that enable wireless communication with a wireless terminal 300 and receive wireless power (AC power) from the wireless terminal 300, an IC card connector 130 that enables wireless communication with a wired terminal 400 and receives DC power, a power management unit 140, a biometric information recognition sensor 150, a security CPU 160, a security chip 170, and a memory unit 180.

[0028] When the fingerprint recognition card 100 registers a user's fingerprint via wireless power supplied from the wireless terminal 300, the wireless power is supplied impulsively with a time delay, and therefore not continuously, making it difficult to use with the power required for fingerprint registration.

[0029] Therefore, while the fingerprint recognition card 100 according to the present invention can be used to provide the necessary power for fingerprint registration when power is supplied via a wired connection rather than wirelessly, the power supplied via wireless connection is insufficient. To solve this problem, the present invention provides a power supply film 200, which is provided separately, to enable the card to receive the necessary power for fingerprint registration.

[0030] The wireless terminal 300 may include an NFC (Near Field Communication) or RFID terminal (including a reader).

[0031] The controller 120 can receive data and wireless power wirelessly from the wireless terminal 300 via the antenna 110. The supplied wireless power can be sent to the power management unit 140.

[0032] The IC card connector 130 can function as a terminal to receive data transmission and reception and DC power supply via a wired connection from the wired terminal 400. When a fingerprint recognition card 100 is inserted into the socket, the socket is connected to the wired terminal 400 via a wired connection to receive DC power, which can be sent to the power management unit 140, and the data can be sent to the controller 120.

[0033] The power management unit 140 can perform a power control function that converts the AC power, which is wireless power input from the controller 120, into DC power, determines the optimal power source from the input power sources, and supplies power to the biometric information recognition sensor 150, security CPU 160, and security chip 170.

[0034] The biometric information recognition sensor 150 can sense and acquire biometric information such as the user's fingerprints.

[0035] When power is supplied to the security CPU 160 via the antenna 110 or IC card connector 130, it can acquire a biometric image of the user from the biometric information recognition sensor 150 and compare it with a fingerprint template pre-stored and registered in the memory unit 180 to determine whether or not they match.

[0036] The security CPU 160, upon comparing the user's biometric information image with a fingerprint template, activates the security chip 170 if a match is found. The security chip 170 then encrypts the CID (Card Identification Number) information, which is data stored in the memory unit 180 and serves as a card security code, and transmits it to the wireless terminal 300 or wired terminal 400.

[0037] Additionally, the card security code may be the card number if the fingerprint recognition card 100 is a credit card.

[0038] Then, the wireless terminal 300 or wired terminal 400 can perform actions such as payment authorization or unlocking entrance / exit doors, depending on the terminal's function.

[0039] The memory unit 180 can store biological information acquired from the biological information recognition sensor 150 or various recognition devices.

[0040] The fingerprint recognition card 100 may be equipped with an LED lamp 102 to indicate its operating status.

[0041] Furthermore, the LED lamps 102 can be provided individually or in multiple units. If multiple units are provided, they can be configured to blink and display different colors to indicate different operating states.

[0042] The fingerprint recognition card 100 can receive a unique identifier generation command from a wireless terminal 300 or a wired terminal 400 and generate a unique identifier corresponding to the recognized fingerprint. The unique identifier can be stored in an encrypted state. The generated unique identifier can be stored in the memory unit 180.

[0043] A method for registering a user's fingerprint for a fingerprint recognition card 100 using a power supply film 200 according to one embodiment of the present invention is as follows:

[0044] A method for registering a user's fingerprint for a fingerprint recognition card according to one embodiment of the present invention includes a first step (S10) of removing the protective film from the power supply film 200, Following the first step, a second step (S20) is taken to attach the power supply film 200 to one side of the fingerprint recognition card 100 so that the power from the paper battery 210 in the power supply film 200 is supplied to the fingerprint recognition card 100, Following the second step, a third step (S30) is performed in which power is supplied to the CPU 230 in the power supply film 200, Following the third step, the CPU 230 transmits a command signal for registering the user's fingerprint using the fingerprint recognition card 100 to the security CPU 160 of the fingerprint recognition card 100 in a fourth step (S40), After the fourth step, when the user's fingerprint is entered into the fingerprint recognition sensor 150 of the fingerprint recognition card 100, the security CPU 160 extracts the user's fingerprint template in the fifth step (S50), After the fifth step, the sixth step (S60) is to save the fingerprint template in the memory unit 180 of the fingerprint recognition card 100, The process may include a seventh step (S70) after the sixth step, in which the power supply film 200 is removed from the fingerprint recognition card 100. During the second step (S20), the contact terminals formed on the power supply film 200 can contact the card contact terminals formed on the fingerprint recognition card 100, thereby connecting the IC connector 240 of the power supply film 200 and the IC card connector 130 of the fingerprint recognition card 100.

[0045] Furthermore, when the IC connector 240 of the power supply film 200 and the IC card connector 130 of the fingerprint recognition card 100 are connected during the execution of the second step (S20), the current sensor 220 in the power supply film 200 can supply power to the CPU 230 from the paper battery 210 in the power supply film 200.

[0046] Furthermore, during the execution of step 5 (S50), fingerprint information can be entered multiple times via the fingerprint recognition sensor 150 of the fingerprint recognition card 100. At this time, the LED lamp 102 can be indicated by flashing each time fingerprint information is entered.

[0047] Furthermore, once the extraction of a valid fingerprint template is complete and encryption and storage are finished, the LED lamp 102 will blink to indicate that the fingerprint template extraction operation is complete. At this time, the LED lamp 102 can blink in a different color than the one that blinks when fingerprint information is entered.

[0048] The power supply film 200 can be removed from the fingerprint recognition card 100 and discarded. Therefore, the power supply film 200 can be used as a disposable item.

[0049] A method for registering a user's fingerprint on a fingerprint recognition card 100 using a power supply film 200 according to one embodiment of the present invention is characterized by providing a separate power supply film 200 that adheres to the fingerprint recognition card 100 during fingerprint registration to provide the power necessary for fingerprint registration.

[0050] Therefore, a fingerprint recognition card 100 using the power supply film 200 according to one embodiment of the present invention does not need to have a built-in battery.

[0051] The method for storing and registering a user's fingerprint information in the memory unit 180 of the fingerprint recognition card 100 of the present invention can be carried out as follows.

[0052] Conventionally, registering a user's fingerprint information in the memory unit 180 may require a computer and a card reader for fingerprint registration.

[0053] The computer may have a related program installed that is capable of storing fingerprint information in the memory unit 180 of the fingerprint recognition card 100 of the present invention.

[0054] The card reader can be connected to a computer via a wired connection, and a fingerprint recognition card 100 can be inserted to send and receive data.

[0055] Therefore, by running the relevant program on a computer to proceed with fingerprint information registration, the fingerprint recognition sensor 150 of the fingerprint recognition card 100 attempts to recognize the user's fingerprint information multiple times (for example, 8 to 12 times) by changing its orientation. The recognized and acquired fingerprint information can then be stored in the memory unit 180 and made available for use as a fingerprint template.

[0056] However, the present invention does not require such a computer and card reader, and allows for easy registration of the user's fingerprint information via the fingerprint recognition card 100 and power supply film 200.

[0057] Thus, the fingerprint recognition card 100 can be pre-loaded with the user's unique biometric information, such as fingerprints, and can be used as an authorization means for payment authorization or control of various entrances and exits in conjunction with various terminals as needed.

[0058] For example, when used as an authorization means for controlling entrances and exits, an access authentication system using fingerprint recognition may typically have a fingerprint recognition device 500 installed on one side of the entrance / exit, and after registering the user's fingerprint in advance, when using the entrance / exit, the user attempts to recognize the fingerprint by touching the fingerprint recognition unit 510 with their finger at the fingerprint recognition unit 500. If the fingerprint matches the registered information, the use of the entrance / exit may be authorized.

[0059] The present invention enables the authorization of entry and exit to an entrance / exit by linking a fingerprint recognition device 500 and a fingerprint recognition card 100, without using a server that stores fingerprint information for managing fingerprint information.

[0060] Since the fingerprint recognition card 100 stores the user's personal biometric information, when the user places their finger in contact with the fingerprint recognition device to attempt fingerprint recognition, the recognized fingerprint information is temporarily transmitted to the fingerprint recognition card 100. At this time, when the fingerprint recognition card 100 is connected (inserted, etc.) to the fingerprint recognition device 500, it is possible to compare it with the fingerprint template, which is biometric information stored inside the fingerprint recognition card 100, and determine whether or not a match is found.

[0061] In other words, since the fingerprint recognition card 100 has the user's fingerprint template stored in advance, it can act as a separate server when the fingerprint recognition device 500 is used.

[0062] According to one embodiment of the present invention, a fingerprint recognition card 100, upon receiving a transmission of a fingerprint image acquired by recognizing fingerprint information, which is biometric information, from the fingerprint recognition unit 510 of a fingerprint recognition device 500, can compare it with a fingerprint template stored in the memory unit 180 using the security CPU 160.

[0063] Therefore, if the comparison results show that the transmitted fingerprint image matches the stored fingerprint template, the security chip 170 transmits the matching result data to the fingerprint recognition device. The fingerprint recognition device 500 then issues a command to the door lock device 600, which opens or closes the entrance, approving entry and exit and causing the entrance to open.

[0064] Another example would be a method of using fingerprint information to process card payments.

[0065] When used as a card for settling various payments, if the fingerprint recognition card 100 of the present invention is connected to a card terminal and the user's finger is placed in contact with the fingerprint recognition sensor 150 provided on the fingerprint recognition card 100 to attempt fingerprint recognition, fingerprint information will be recognized. The recognized fingerprint information will be compared with a fingerprint template stored in the memory unit 180 by the security CPU 160 located inside the fingerprint recognition card 100, and if a match is found, the security chip 170 will transmit a card security code to the card terminal to initiate the payment authorization procedure.

[0066] Although this invention has been described in relation to fingerprint recognition cards that register a user's fingerprint information, it is not limited to this and can also be applied to cases where other biometric information such as finger vein patterns, facial features, or iris patterns are stored on the card.

[0067] Next, the second and third embodiments of the fingerprint recognition card of the present invention will be described in more detail. Conventional biometric authentication has the problem that the biometric information of the biometric authentication customer is stored in a server on the network or in the memory of the recognition device itself, which is a specific storage means of the biometric authentication service provider. Conventionally, if the storage means is stolen or hacked by an external intruder, there is a problem that the user's unique information may be leaked, causing enormous damage to the user.

[0068] Conventionally, if biometric information used for authentication in various opening / closing devices and e-commerce is leaked to the outside, for example, all opening / closing devices and e-commerce systems that use fingerprint information will authenticate the fraudulent user using the leaked fingerprint information as a legitimate user. This poses a problem that could cause enormous damage to users who widely utilize biometric information.

[0069] The fingerprint recognition card of the present invention is a biometric authentication card (used in the same term as "fingerprint recognition card" in this invention) that stores biometric information on a card, which is a storage medium that the user may possess, and enables authentication via communication with a terminal.

[0070] Therefore, since there is no need to store and utilize biometric information on an external storage device such as a server, as in the past, problems such as server theft and hacking can be fundamentally solved.

[0071] The biometric authentication card of the present invention can receive power for the authentication procedure from a power management unit when connected to a wireless or wired terminal, without storing a separate battery inside. This fundamentally solves the problem of deterioration or damage to the battery inside the biometric authentication card during long-term use, and as a result, it can be used without any problems even during long-term use.

[0072] Figure 8 shows a second embodiment in which the authentication procedure is performed on the terminal.

[0073] The components (elements) provided inside the biometric authentication card 10 may include a communication module (such as an NFC module) 11 for communicating with the terminal 20, a power management unit 12, a memory unit consisting of a first memory 13 and a second memory 14, a security CPU 15, and a security chip 16.

[0074] The communication module 11 may include an antenna for near-field communication (NFC) and a controller for controlling the communication status.

[0075] The power management unit 12 can receive wireless power input from the terminal 20 and control the operation of each component of the biometric authentication card 10 (security CPU 15, security chip 16, etc.).

[0076] Furthermore, the first memory 13 (M1) can store the biometric information of the user (owner) of the biometric authentication card 10 in advance, and the second memory 14 (M2) can receive and store newly entered biometric information.

[0077] Authentication can be performed by including the following steps: a first step of touching or bringing a biometric authentication card close to a terminal; a second step of receiving terminal information from the terminal using the biometric authentication card; a third step of transmitting a biometric template stored in the biometric authentication card to the terminal; a fourth step of acquiring new biometric information via the biometric recognition unit of the terminal; and a fifth step of performing an authentication procedure within the terminal based on the information of the terminal.

[0078] Figure 9 shows a third embodiment in which the authentication procedure is performed within the biometric authentication card.

[0079] Authentication can be performed by including the following steps: a first step of acquiring new biometric information of the user via the biometric information recognition unit of the terminal; a second step of touching or bringing a biometric information authentication card close to the terminal; a third step of temporarily storing the new biometric information acquired from the terminal in the biometric information authentication card based on the terminal information received by the biometric information authentication card; a fourth step of performing an authentication procedure to determine whether or not a match exists by comparing the new biometric information temporarily stored in the biometric information authentication card with reference biometric information stored in the biometric information authentication card; and a fifth step of transmitting the authentication result data to the terminal for temporary storage and performing a procedure in the terminal according to the authentication result.

[0080] On the other hand, as described above, an embodiment is also possible in which a fingerprint recognition sensor 150 is built into the fingerprint recognition card 100. With the fingerprint recognition sensor 150 installed in the fingerprint recognition card 100, new biometric information can be received via the fingerprint recognition sensor 150, compared with reference biometric information previously stored in the fingerprint recognition card 100 to determine whether or not there is a match, perform an authentication procedure, and send the authentication result data to the terminal to perform an approval procedure.

[0081] In particular, when the fingerprint recognition card 100 is used by receiving wireless power via a wireless terminal, there may not be enough power to store and register the user's biometric information, such as fingerprint information.

[0082] When the user's fingerprint information is recognized via the fingerprint recognition sensor 150 built into the fingerprint recognition card 100, power can be supplied via the power supply film 200 described above as a separate power supply means.

[0083] The present invention relates to a power supply film that adheres to a fingerprint recognition card and supplies power to the fingerprint recognition card, wherein the power supply film may include a paper battery that supplies power and a current sensor that is activated to supply power to the paper battery when the power supply film is attached to the fingerprint recognition card.

[0084] A power supply film can be provided that includes a CPU that receives power from the paper battery based on a signal output by the activation of the current sensor and controls the supply of power to the fingerprint recognition card, and an IC connector connected to the fingerprint authentication card, through which the CPU transmits command signals for registering the user's fingerprint template into the fingerprint recognition card.

[0085] Furthermore, the present invention provides a method for registering a user's fingerprint for a fingerprint recognition card, comprising: a first step of removing the protective film from the power supply film; a second step of attaching the power supply film to one side of the fingerprint recognition card after the first step so that power from the paper battery in the power supply film is supplied to the fingerprint recognition card; a third step of supplying power to the CPU in the power supply film after the second step; a fourth step of the CPU transmitting a command signal for registering the user's fingerprint by the fingerprint recognition card to the security CPU of the fingerprint recognition card after the third step; a fifth step of the security CPU in the fingerprint recognition card extracting the user's fingerprint template after the fourth step when the user's fingerprint is input to the fingerprint recognition sensor of the fingerprint recognition card; a sixth step of storing the fingerprint template in the memory section of the fingerprint recognition card after the fifth step; and a seventh step of removing the power supply film from the fingerprint recognition card after the sixth step.
