Technical Field

The invention relates to the field of card manufacturing of smart cards, in particular to a fingerprint verification type smart card, a verification method thereof and a computer readable storage medium.

Background

With the development of electronic technology, smart cards are widely used in many fields of people's daily life and industrial production. Common smart cards include bank cards, communication cards installed in mobile phones, bus cards, access cards, various membership cards and the like, and the existing smart cards are provided with a card base in which an intelligent chip is installed.

The existing smart card is provided with a fingerprint sensor, the smart card acquires fingerprint information of a user in advance through the fingerprint sensor and stores the fingerprint information in a security chip, when the user needs to perform payment transaction, verification fingerprint information of the user needs to be acquired through the fingerprint sensor, the security chip compares the acquired verification fingerprint information with pre-recorded fingerprint information, if the verification fingerprint information is consistent with the pre-stored fingerprint information, the verification fingerprint information passes through fingerprint verification and allows the payment transaction to be performed; if the verification fingerprint information is not consistent with the pre-stored fingerprint information, the fingerprint verification is not passed and the payment transaction is not allowed to be executed.

The fingerprint verification type intelligent card has the advantages that card using safety and convenience are greatly considered in the transaction process, so that the intelligent card is prevented from being used without authorization of a cardholder, and the intelligent card cannot be normally used after being acquired by a non-cardholder; the traditional password type smart card is prevented from being peeped or recorded in the password input process, so that the risk of disclosure is avoided; meanwhile, compared with password input, fingerprint verification is more convenient, and public facilities such as a password keyboard do not need to be contacted, so that the risk of virus and bacteria infection is avoided. Therefore, fingerprint authentication type smart cards are increasingly popular with users, and the number of issued smart cards is gradually increasing.

However, the following problems also occur in the use of the fingerprint authentication type smart card:

the first is that the accuracy of fingerprint verification is not high. Because certain false rejection rate and false acceptance rate exist during fingerprint verification, it is determined that fingerprint verification operation is not completely successful, especially under the condition that a finger of a user is polluted or the finger is in poor contact with a fingerprint sensor, fingerprint verification may need to be performed for many times, while a transaction is in progress, the transaction time is increased due to the fingerprint verification for many times, especially on the occasion with a transaction time limit, the transaction time is possibly exceeded due to the fingerprint verification performed for many times, so that the transaction is failed, and the user experience is poor.

Secondly, the limitation of the use scene, for the machines of the types such as ATM, the smart card needs to swallow the ATM machine for transaction, and the fingerprint verification can not be carried out, so that the fingerprint verification function can not be used on the ATM machine.

The third is the limitation of service handling, for the scene that the smart card needs to be handed to the handling personnel for handling, if the counter service handling, the smart card is operated in the counter at the moment, and the card holder is inconvenient to go to the inside of the counter to carry out fingerprint verification on the smart card, which results in poor using effect.

Because the existing fingerprint verification type smart card has the use limitation, the popularization and the use of the smart card are influenced.

Disclosure of Invention

The first purpose of the invention is to provide a fingerprint verification type smart card verification method which is convenient for users to use and has less limitation on use scenes and service scenes.

A second object of the present invention is to provide a fingerprint verification-type smart card applying the above verification method.

A third object of the present invention is to provide a computer-readable storage medium for implementing the authentication method of the fingerprint authentication type smart card described above.

In order to achieve the first object of the present invention, the verification method of the fingerprint verification type smart card provided by the present invention comprises obtaining a pre-verification instruction, obtaining verification fingerprint information input by a user, and verifying the verification fingerprint information; if the fingerprint information passes the verification, setting the verification information of the security chip as pre-authorization and setting the valid period of the pre-authorization; and if a transaction verification request instruction is received, obtaining verification information recorded by the security chip, if the verification information is pre-authorized, passing the transaction authentication request, and otherwise, prompting to execute real-time fingerprint verification operation.

According to the scheme, before payment transaction is not carried out, the user can carry out pre-verification operation, namely fingerprint verification operation in advance, and the security chip records pre-authorization information. When the transaction is needed, the fingerprint verification operation is not needed to be carried out again, and the security chip directly obtains the pre-authorized information and carries out corresponding payment operation. Therefore, the operation of multiple times of verification due to the failure of fingerprint verification in the transaction process can be avoided, and the transaction time can be effectively shortened; in addition, aiming at special scenes such as ATM machines or counter operation and the like, corresponding transaction can be completed in a pre-verification mode, and the use scene limitation of the fingerprint verification type intelligent card is greatly reduced.

Preferably, the verification information is set to be unauthorized after the transaction authentication request is passed.

Therefore, the successful result of the one-time pre-verification operation of the user can only be used once, namely the pre-authorization result cannot be reused, so that lawbreakers can be prevented from using the pre-authorization loophole to carry out illegal transactions, and the use safety of the smart card is improved.

The further scheme is that the safety chip sets the verification information as unauthorized after the expiration date is over.

It can be seen that even if the result of the pre-authorization is not used, if the valid period of the pre-authorization is over, the result of the pre-authorization will automatically fail, so that the lawless persons can be prevented from using the result of the pre-authorization to engage in illegal transactions.

In a further scheme, the power module supplies power to the security chip only when the fingerprint information is verified and the verification information is changed.

Therefore, the time for the safety chip to use electricity is very short, the problem that the intelligent card consumes too high energy due to long-time electricity consumption of the safety chip can be avoided, and the intelligent card can be ensured to be used for a long time under the condition of using the storage battery for supplying power.

The fingerprint verification type intelligent card is further provided with a verification indication module; if the fingerprint information passes the verification, the verification indicating module sends a first verification indicating signal; if the fingerprint information is not verified, the verification indicating module sends out a second verification indicating signal.

Therefore, the user can know the current fingerprint verification result through the information sent by the verification indicating module, if the fingerprint verification result does not pass the verification, the user can perform the verification again, and the situation that the user finds that the fingerprint verification does not pass the verification during the transaction is avoided.

In a further aspect, the verification instruction module issues a third verification instruction signal if the complete verification fingerprint information is not extracted.

Therefore, if the fingerprint sensor cannot extract complete fingerprint information, the fingerprint sensor cannot perform comparison operation of the fingerprint information, and the operation of fingerprint verification cannot be completed. Therefore, by sending the third verification indication signal, the user can know the current fingerprint verification result in time, and the fingerprint information is collected again.

The further scheme is that a pre-verification key is arranged on the fingerprint verification type intelligent card; obtaining the pre-validation instruction includes: and acquiring a signal that the pre-verification key is pressed.

Therefore, when the user carries out fingerprint verification, the user only needs to press the pre-verification key to start executing the pre-verification operation, and the fingerprint sensor and the safety chip are started to work, so that the problem that the power consumption is overlarge due to the fact that the fingerprint sensor and the safety chip work for a long time can be avoided.

In order to achieve the second object, the fingerprint verification type smart card provided by the present invention includes a card base, a security chip and a fingerprint sensor are disposed in the card base, a processor and a memory are further disposed in the card base, a computer program is stored in the memory, and each step of the fingerprint verification type smart card can be implemented when the processor executes the computer program.

Preferably, a storage battery and an induction coil are arranged in the card base, and the safety chip is powered by the storage battery and/or the induction coil.

Therefore, the security chip can be powered by multiple modes, when the smart card is inserted into a card reader or transacts in a non-contact mode, external electric energy can be acquired and the security chip is powered, if the smart card is not in a transaction stage, the battery is used for supplying power to the security chip, and the security chip can be ensured to receive a stable power supply.

To achieve the third objective, the present invention provides a computer-readable storage medium having a computer program stored thereon, where the computer program is executed by a processor to implement the steps of the authentication method for fingerprint authentication smart cards.

Fig. 2 is a flowchart of an embodiment of a method for authenticating a fingerprint authentication smart card according to the present invention.

The invention is further explained with reference to the drawings and the embodiments.

Detailed Description

The verification method of the fingerprint verification type intelligent card is applied to the fingerprint verification type intelligent card, a safety chip and a fingerprint sensor are arranged in a card base of the intelligent card, a processor and a memory are further arranged, preferably, a computer readable storage medium is stored in the memory, and when the processor executes a computer program of the computer readable storage medium, all steps of the verification method of the fingerprint verification type intelligent card can be realized.

Fingerprint verification type smart card embodiment:

referring to fig. 1, the present embodiment has a card base 10, preferably, the card base 10 is a rectangular card base, the card base may be made of plastic, and a security chip 15, a controller 16 and a fingerprint sensor 18 are disposed in the card base 10, wherein the security chip 15 stores financial transaction information and pre-entered fingerprint information, the pre-entered fingerprint information is referred to as reference fingerprint information, the security chip 15 stores a fingerprint comparison success indicator, the indicator is a binary value, for example, a binary number "1" is used to indicate that the fingerprint comparison is successful, i.e., pre-authorization, and a binary number "0" is used to indicate that the fingerprint comparison is unsuccessful, i.e., unauthorized.

The controller 16 is a microcontroller for controlling the operation of the fingerprint sensor 18 and may communicate with the security chip 15. Preferably, a processor and a memory are arranged in the controller 16, the memory is stored with a computer readable storage medium, and when the processor executes a computer program of the computer readable storage medium, the steps of the authentication method of the fingerprint authentication type smart card can be realized.

In order to supply power to the security chip 15, the controller 16 and the fingerprint sensor 18, a power module is disposed on the card base 10, the power module of this embodiment includes a storage battery 12 and a power processing module 14, the storage battery 12 supplies power to the power processing module 14, and the power processing module 14 supplies power to the security chip 15, the controller 16 and the fingerprint sensor 18 after voltage stabilization, filtering and other processing are performed on the received voltage.

And, the card base 10 is further provided with an induction coil 11, when the smart card approaches the contactless transaction device, the induction coil 11 will generate an induction current, and the power processing module 14 can receive the induction current and supply power to the security chip 15, the controller 16 and the fingerprint sensor 18 after voltage conversion.

In addition, the card base 10 is further provided with an SE contact carrying module 13, the SE contact carrying module 13 is a module conforming to the 7816 standard size design, and when the smart card is connected with a contact type card reading device, the SE contact carrying module 13 is connected with an electrical contact of the contact type card reading device and obtains electrical energy, and meanwhile, the SE contact carrying module supplies power to the power supply processing module 14.

Thus, the smart card may obtain power in a number of ways, such as by being powered by the battery 12, by being induced by the induction coil 11, or by contacting the carrier tape module 13 by SE. Preferably, when the induction coil 11 obtains the induction current or the belt module 13 obtains the power in a contact manner through SE contact, the storage battery 12 stops supplying power to the power processing module 14, so as to avoid too fast consumption of the power of the storage battery 12 and ensure that the storage battery 12 can be used for a long time. Specifically, the power processing module 14 is provided with a switch, and when the induced current is detected or the SE contacts the carrier tape module 13 to supply power, the connection between the power processing module 14 and the storage battery 12 is disconnected, so as to prevent the storage battery 12 from discharging. When no induction current is detected or the SE contacts the carrier tape module 13 to supply power, the storage battery 12 and the power supply processing module 14 are automatically connected.

Since the fingerprint authentication operation is usually performed before the transaction is executed, the operation such as fingerprint authentication usually requires the use of the electric energy of the battery 12, and the smart card can be ensured to be used for a long time by automatically switching the power supply. Preferably, the electric energy stored in the storage battery 12 should meet the electric energy use requirement of the smart card for 3 years to 4 years.

In addition, the card base 10 is further provided with a pre-authentication key 17, and when the user presses the pre-authentication key 17, the controller 16 starts the fingerprint authentication operation. Since there are three results often in the user's fingerprint verification: the card base 10 is provided with a verification indication module 19 for the user to clearly know the current verification result, and the verification indication module 19 of the embodiment is a three-color indicator light, for example, a red, green and yellow indicator light can be emitted. When the fingerprint verification of the user is successful, the green indicating lamp emits light, if the fingerprint verification is unsuccessful, the red indicating lamp emits light, and if the fingerprint verification information is not completely extracted, the yellow indicating lamp emits light. Of course, the verification indication module 19 may also be a color indicator light to indicate different results in different display states. For example, when the user fingerprint verification is successful, the indicator light is normally on, if the fingerprint verification is unsuccessful, the indicator light flashes at a first frequency, and if the complete verification fingerprint information cannot be extracted, the indicator light flashes at a second frequency.

The embodiment of the verification method of the fingerprint verification type smart card comprises the following steps:

the following describes a specific flow of the authentication method of the fingerprint authentication type smart card with reference to fig. 2. First, in step S1, the controller 16 of the smart card determines whether a pre-authentication command is received. Specifically, it is determined whether a signal that the user presses the pre-authentication key 17 is received, and if the pre-authentication key 17 is pressed, and if the pre-authentication signal is not received by the controller 16, it indicates that the user does not need to perform the pre-authentication operation currently, the waiting is continued. Preferably, the power module does not supply power to the security chip 15 and the fingerprint sensor 18 when the user does not need to perform the pre-authentication operation, so as to save the power of the storage battery.

If the pre-authentication instruction is received, step S2 is executed to collect the fingerprint information of the user by the fingerprint sensor 18. In this embodiment, the fingerprint information collected by the fingerprint sensor 18 is referred to as verification fingerprint information. After the fingerprint sensor 18 collects the fingerprint information, the fingerprint information is sent to the security chip 15, and the security chip 15 verifies the verified fingerprint information.

Next, step S3 is executed, and the secure chip 15 determines whether the verification fingerprint information is verified. Specifically, the security chip 15 stores therein reference fingerprint information previously entered by the user, so that step S3 is to compare the verification fingerprint information with the reference fingerprint information, and if the verification fingerprint information is consistent with the reference fingerprint information, it is determined that the verification fingerprint information passes the verification, and step S4 is executed to set the verification information recorded by the security chip 15 as pre-authorization. For example, a binary number of one bit is set in the security chip 15 as the verification information, a binary number "1" is used to indicate pre-authorization, and a binary number "0" is used to indicate non-authorization. Setting the authentication information to pre-authorization is to modify the binary number to "1".

In addition, the security chip 15 also sets a valid period of pre-authorization, for example, the valid period of pre-authorization is 20 minutes or 30 minutes. Preferably, the valid period of the pre-authorization is the time fixedly set by the smart card, the user is not allowed to modify the valid period of the pre-authorization by himself, and the valid period of the pre-authorization starts to be counted immediately after the verification information is set as the pre-authorization.

In addition, if the verification fingerprint information is verified, the security chip further sends a signal to the verification indication module 19 to confirm that the verification fingerprint information is verified, and at this time, the verification indication module 19 sends a first verification prompt message, such as a green indicator light or a normally bright light, so that the user can know the verification result.

If the judgment result of the step S3 is no, that is, the fingerprint information is not verified, then step S9 is executed to set the verification information to unauthorized, for example, to set the binary number stored in the secure chip 15 to "0". Meanwhile, the verification indication module 19 issues a second verification prompt message, for example, a red indicator lamp or a flashing light with a first frequency, so that the user can know the verification result. Of course, the user may perform fingerprint authentication again, for example, press the pre-authentication key 17 again, and fingerprint information of the user is collected again by the fingerprint sensor 18.

Certainly, there is also a case where the fingerprint sensor 18 collects the fingerprint information of the user, that is, the complete verification fingerprint information cannot be extracted, in this case, the security chip 15 cannot identify the verification fingerprint information, the security chip 15 sends a signal to the verification indication module 19, and the verification indication module 19 sends a third verification prompt message, for example, a yellow indicator lamp emits light or flashes light at a second frequency. The user knows the current verification result according to the third verification prompt message, and can acquire and verify the fingerprint information again.

If the security chip 15 confirms that the authentication fingerprint information of the user is authenticated and sets the authentication information as the pre-authorization, step S5 is performed to determine whether the validity period of the pre-authorization is over, i.e., whether the current time is still within the validity period of the pre-authorization, and if not, step S9 is performed to set the authentication information stored in the security chip 15 as unauthorized, i.e., to modify the specific binary number from "1" to "0". Therefore, the pre-authorization verified by the fingerprint is only effective in a short time, and if the valid period is exceeded, the pre-authorization is invalid, so that the loss of a user and a bank caused by illegal operation by a lawbreaker by utilizing the long valid period of the pre-authorization can be avoided.

If the judgment result of the step S5 is yes, that is, the current time is still within the pre-authorized valid period, step S6 is executed to judge whether the transaction verification request command is received. Specifically, when the user uses the smart card to perform a payment transaction, for example, the smart card is inserted into a contact-type card reader, or the smart card is close to a contactless card reader, the security chip 15 of the smart card receives a transaction verification request instruction after the merchant initiates a payment transaction request through the card reader. Step S6 is to determine whether the instruction is received, and if so, it indicates that the user is currently performing payment transaction using the smart card.

If the determination result in the step S6 is yes, step S7 is executed to determine whether the currently stored verification information of the security chip 15 is pre-authorized, that is, whether the specific binary number is "1", if so, indicating that the current verification information is pre-authorized, step S8 is executed, the transaction verification request is passed, otherwise, indicating that the current verification information is unauthorized, step S10 is executed to prompt to execute a real-time fingerprint verification operation, for example, execute a normal fingerprint verification process, that is, obtain the fingerprint information of the user in real time, and verify the fingerprint information of the user.

After the current transaction verification request is passed, step S9 is also executed to set the verification information to unauthorized, i.e., to modify the binary number recorded by the secure chip 15 to "0". Therefore, after the user passes the fingerprint verification each time, the pre-authorization information can be used only once and is not allowed to be used for multiple times, so that illegal persons can be prevented from carrying out illegal operation by using the pre-authorization information of the user.

Preferably, after the verification information is converted from pre-authorization to unauthorized, the verification indication module may send out indication information, for example, send out second indication verification information, that is, the red indicator light is illuminated, so that the user can know the state change of the verification information.

In addition, in order to reduce the power consumption of the battery 12, the power supply module supplies power to the security chip 15 only when the fingerprint information is verified and when the verification information is changed, and does not supply power to the security chip 15 at other times. Specifically, after the user presses the pre-authentication key 17, the storage battery 12 supplies power to the fingerprint sensor 18 and the security chip 15 through the power processing module 14, the fingerprint sensor 18 collects fingerprint information of the user, and the security chip 15 authenticates the fingerprint information. When the security chip 15 obtains the verification result and modifies the verification information, for example, the verification information is set as pre-authorized or unauthorized, the power module stops supplying power to the fingerprint sensor 18 and the security chip 15, so as to avoid excessive consumption of the storage battery 12.

Of course, if the validity period of the pre-authorization is over, or the transaction verification request message is passed, the security chip 15 needs to modify the verification message, and at this time, the power module also supplies power to the security chip 15, so that the security chip 15 updates the verification message.

Preferably, if the smart card has a life span, for example, five years for a credit card, the capacity of the battery 12 may be set so that the power of the battery 12 can meet the power demand of the security chip 15 or the like only within the life span of the credit card, so that even if a lawbreaker picks up an expired credit card discarded by the user, it is difficult to perform a payment transaction using the credit card.

Therefore, the fingerprint verification type intelligent card provided by the invention allows a user to extract and execute pre-verification, for example, the pre-verification is carried out in a period of time before payment transaction is carried out, so that the pre-verification can be avoided when the payment transaction is carried out, the problem that the transaction time is too long due to the fact that multiple times of verification are required because the fingerprint verification is unsuccessful is avoided, and the user experience is improved. In addition, the user can perform pre-verification and can use the fingerprint verification type intelligent card in scenes such as ATM machines, counters and the like, so that the problem that the use scene of the existing fingerprint verification type intelligent card is limited can be well solved. Meanwhile, the card can be used only once due to pre-authorization and the limitation of the valid period, so that the card using safety of a user can be guaranteed.
