Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with one or more embodiments of the present specification. Rather, they are merely examples of apparatus and methods consistent with aspects of one or more embodiments of the present description as detailed in the accompanying claims.

It should be noted that: in other embodiments, the steps of the corresponding method are not necessarily performed in the order shown and described in this specification. In some other embodiments, the method may include more or fewer steps than described in this specification. Furthermore, individual steps described in this specification, in other embodiments, may be described as being split into multiple steps; while various steps described in this specification may be combined into a single step in other embodiments.

In order to solve the technical problem that the risk of communication failure is high, the embodiment of the application provides an access control authentication method, which can acquire fingerprint data of a cardholder of an access control card according to a fingerprint acquisition instruction before the access control card communicates with access control equipment, perform fingerprint authentication by utilizing the fingerprint data of the cardholder and preset fingerprint template data in the access control card, determine the fingerprint identification state of the access control card, and perform access control authentication when the access control card communicates with the access control equipment according to the fingerprint identification state based on the authentication type of the access control card.

Fig. 1 is a schematic diagram of an internal module of an access card according to an embodiment of the present application. Fig. 2 is a schematic flow chart of an access control authentication method applied to an access control device according to an embodiment of the present application.

As shown in fig. 1, the access authentication method of the present application can be applied to an access card 10. The access authentication method can also be applied to the mobile terminal with the access card 10. By way of example, the mobile terminal may include a smart phone, a smart watch, and the like. And are not exemplified here.

Referring to fig. 1, an access card 10 will be described as an example. The access card 10 may include a chip 11. The chip 11 can encrypt the hardware security, encrypt the data, and realize the security communication. The access card 10 may comprise an active access card, among other things. The active access card may include an energy storage power source 13, where the energy storage power source 13 may be configured to store electrical energy to provide electrical energy to the access card 10. The stored energy power source 13 may be a battery, for example. Thus, the access card 10 is portable and can be used alone.

As shown in fig. 2, the access authentication method according to the embodiment of the present application may include the following steps 110 to 140:

step 110, acquiring a fingerprint acquisition instruction before the access card communicates with the access control device.

The access card communication with the access device may include non-contact communication of the access card with the access device and contact communication of the access card with the access device. The fingerprint collection instruction is used for collecting fingerprint data of a cardholder of the access card.

As shown in fig. 1, the access card 10 may include a power control module 14 and a fingerprint acquisition module 12.

The power supply control module 14 is connected with the energy storage power supply 13, and the power supply control module 14 is respectively connected with the chip 11 and the fingerprint acquisition module 12. The key (not shown) of the power supply control module 14 is used for conveniently controlling the power supply on/off of the fingerprint acquisition module 12 and the chip 11. When the key is pressed or not pressed, the power supply control module 14 controls the energy storage power supply 13 to start power supply or to cut off power supply. The fingerprint acquisition module 12 is used for acquiring fingerprint data of a cardholder.

With continued reference to fig. 1, the energy storage power supply 13 is respectively connected with the fingerprint acquisition module 12 and the chip 11. In this way, the energy storage power supply 13 can supply power to the fingerprint acquisition module 12 and the chip 11 through the power supply control module 14. When the key is powered on, the energy storage power supply 13 supplies power to the chip 11 through the power supply control module 14, so that the chip 11 sends out a fingerprint acquisition instruction, and the fingerprint acquisition and comparison function can be started.

And 120, acquiring fingerprint data of a cardholder of the access card according to the fingerprint acquisition instruction.

A cardholder refers to a person who needs to communicate with an access device using an access card. The cardholder may be the owner of the access card corresponding to the preset fingerprint template data. The cardholder may also be a person other than the host. In actual use, the owner of the access card loses the access card, and other people impersonate the access card, so that fingerprint data of the cardholder needs to be acquired, fingerprint authentication is carried out on preset fingerprint template data in the access card, whether the cardholder is the owner of the access card is checked, the access card is guaranteed to belong to the owner, and communication of subsequent access equipment is carried out.

Referring to fig. 2, the step 120 may further include determining whether preset fingerprint template data exists in the access card in response to the fingerprint acquisition command; and if the preset fingerprint template data exists in the access card, acquiring the fingerprint data of the cardholder. Therefore, the fingerprint template data can be preset in the access card, the fingerprint data of the cardholder can be obtained, and the obtaining efficiency of the fingerprint data of the cardholder can be improved.

In some examples of applications, as shown in connection with fig. 1, when the key is turned on, a key-on locking signal is generated, where the locking signal is used to lock the energy storage power supply in a power supply state, and during the power-on period of the energy storage power supply 13, the chip 11 sends a fingerprint acquisition instruction to the fingerprint acquisition module 12 to start the fingerprint acquisition and comparison function. If the preset fingerprint template data exists in the access card, the fingerprint data of the cardholder acquired by the fingerprint acquisition module 12 is acquired, and the power-on time length is longer than or equal to the communication time length of the chip 11 and the fingerprint acquisition module 12. So in the duration of the power on of the energy storage power supply 13, the normal power supply of the chip 11 is ensured, and the normal communication between the chip 11 and the fingerprint acquisition module 12 is completed, so that the fingerprint data of a cardholder can be obtained through the fingerprint acquisition module 12. The fingerprint acquisition module 12 acquires fingerprints, extracts fingerprint data, encrypts the fingerprint data, and transmits the encrypted fingerprint data to the chip 11. The chip 11 decrypts the fingerprint data from the encrypted fingerprint data.

Wherein the access card comprises a timeout timer (not shown). When the key is powered on, a start signal is generated when a key-on locking signal is generated; and starting a timeout timer according to a starting signal, wherein the locking signal is used for locking the energy storage power supply in a power supply state within the timing time length of the timeout timer, the timing time length of the timeout timer is equal to the power-on time length, and the timing time length is longer than the communication time between the chip and the fingerprint acquisition module. Therefore, even if the key is released, normal power supply of the chip can be ensured, normal communication between the chip and the fingerprint acquisition module is completed, and communication between the fingerprint access card and the access control system is supported. The method further includes disconnecting the energy storage power supply when the timeout timer reaches the timed duration. Thus, the communication between the chip and the fingerprint acquisition module can be ensured to be completed. And when the chip and the fingerprint acquisition module are not in communication, the fingerprint acquisition module can disconnect the power supply after the power-on time reaches the timing time. Meanwhile, after the power-on time reaches the timing time, the fingerprint acquisition module is closed, so that the power consumption of the access control equipment can be reduced.

The timing duration may be set according to a user requirement, for example, the timing duration may be 200ms to 500ms. The timing duration may also be an average value of communication durations between the fingerprint acquisition module and the chip. And are not limited in detail herein. As long as the timing duration of the communication between the fingerprint acquisition module and the chip can be completed.

And 130, performing fingerprint authentication by utilizing fingerprint data of a cardholder and preset fingerprint template data in the access card, and determining the fingerprint identification state of the access card.

The preset fingerprint template data refers to fingerprint data which is recorded in advance in the access card, and the fingerprint data is of an owner of the access card.

In the step 130, fingerprint authentication is performed by using the fingerprint data of the cardholder and the preset fingerprint template data in the access card, so as to obtain an authentication result of fingerprint authentication, which can reflect whether the cardholder is the owner of the access card. If the result of the fingerprint authentication is the result of the fingerprint authentication failure, it indicates that the cardholder is not the owner of the access card, and the subsequent need is to avoid the cardholder using the access card. If the result of the fingerprint authentication is the result of successful fingerprint authentication, the cardholder is the owner of the access card, and the subsequent cardholder can use the access card.

In connection with fig. 2, the step 110 may further include acquiring a fingerprint acquisition command triggered by the key. Therefore, the fingerprint acquisition instruction can be triggered through the key, real-time acquisition is not needed, and energy is saved. The step 120 may further include: responding to the fingerprint acquisition instruction, and judging whether preset fingerprint template data exist in the access card; if the preset fingerprint template data exists in the access card, acquiring fingerprint data of a cardholder of the access card acquired by a fingerprint acquisition module; the step 130 may further include: comparing whether fingerprint data of a cardholder is consistent with preset fingerprint template data in an access card; if the fingerprint data of the cardholder is inconsistent with the preset fingerprint template data, determining that the fingerprint identification state is a fingerprint authentication failure state; if the fingerprint data of the cardholder is consistent with the preset fingerprint template data, determining that the fingerprint identification state is a fingerprint authentication success state.

The fingerprint identification state is used for indicating whether fingerprint data of a cardholder and preset fingerprint template data are authenticated or not. The fingerprint identification status may be realized by an identification data or an identification indicator light. The fingerprint identification state includes a fingerprint authentication success state, a fingerprint authentication failure state, or a state in which fingerprint authentication is not performed. For example, the successful fingerprint authentication state is set to 1, the failed fingerprint authentication state is set to 0, and the state where no fingerprint authentication is performed is set to null, i.e., null. The data herein are merely illustrative. For example, the successful fingerprint authentication state is set as the lighting signal of the first state indicating unit, the failed fingerprint authentication state is set as the lighting signal of the second indicating lamp, and the state without fingerprint authentication is set as the no lighting signal. This is merely illustrative. The first status indication unit may be a green LED lamp, and the second indication lamp may be a red LED lamp. Therefore, the fingerprint authentication success state or the fingerprint authentication failure state can be conveniently distinguished, and the user can be conveniently reminded according to different colors of lamplight.

As shown in fig. 2, the access card includes a status indication module 18, where the status indication module 18 is configured to indicate whether the status is currently authenticated. The status indication module 18 includes a first status indication unit and a second indicator light, and the status indication module 18 is connected to the fingerprint acquisition module 12. The first status indication unit may be a red LED lamp and the second indication lamp may be a green LED lamp. In practical application, when acquiring a fingerprint acquisition instruction, a red LED lamp is lightened to prompt a cardholder to press the fingerprint. And when the fingerprint authentication by utilizing the fingerprint data of the cardholder and the preset fingerprint template data in the access card is successful, the green LED lamp is turned on. When fingerprint authentication by utilizing fingerprint data of a cardholder and preset fingerprint template data in an access card fails, neither the green LED lamp nor the red LED lamp is lighted.

The access control authentication method of the embodiment of the application is divided into two communication stages, wherein the first stage is a communication stage for carrying out fingerprint authentication on fingerprint data of a cardholder and preset fingerprint template data before the access control card communicates with the access control equipment, and the second stage is a communication stage of the access control card and the access control equipment. The details are as follows.

And 140, based on the authentication type of the access card, performing access authentication when the access card communicates with the access device according to the fingerprint identification state.

The access card has a plurality of authentication types, such as one or more of a unique identification number authentication type and a key authentication type. Of course, other types of authentication of the access card are also possible, and are not exemplified here. The following describes two authentication types, i.e., a unique identification number authentication type and a key authentication type, in detail.

As shown in connection with fig. 1, the access card includes a unique identification number register 15. A unique identification number register 15 is in connected communication with the chip 11. In some embodiments, the embodiment of the application provides an access authentication method further including that the access card includes a unique identification number register 15, and the unique identification number register 15 defaults to storing an invalid identification number; the method further comprises the steps of: for the access card, the authentication type is the unique identification number authentication type, and when the fingerprint identification state is the state of not performing fingerprint authentication, the unique identification number register 15 is determined to store invalid identification numbers, and the fingerprint identification state of the access card is determined to be not performing fingerprint authentication. The invalid identification number refers to data which cannot pass through access control authentication. Illustratively, the invalid identification number is an invalid serial number, and the number of digits of the invalid serial number may be the same as or different from the number of digits of the correct fingerprint card serial number. In this way, the default state in which fingerprint authentication is not performed can be effectively identified so as to be quickly reflected.

The state that fingerprint authentication is not performed refers to that fingerprint template data is not input yet. The fingerprint template data refers to fingerprint data of an owner of the access card which is input for the first time. The fingerprint data of the cardholder of the access card obtained in step 120 may include fingerprint features of the cardholder of the access card, where the fingerprint features of the cardholder of the access card are features extracted by processing the fingerprint data collected by the fingerprint collection module by the chip. Referring to fig. 3, the method further includes the step 230 of extracting fingerprint features of the fingerprint template data by the chip as preset fingerprint template data. The fingerprint characteristics of the cardholder of the access card are conveniently compared with the fingerprint characteristics of the fingerprint template data.

As shown in fig. 2, the step 140 in the access authentication method provided in the embodiment of the present application may further include: when the fingerprint authentication of the fingerprint data of the cardholder fails to be performed with the preset fingerprint template data, the fingerprint identification state of the access card is determined to be the fingerprint authentication failure state, and the unique identification number register 15 is determined to store invalid identification numbers.

As shown in fig. 2, the step 140 in the access authentication method provided in the embodiment of the present application may further include: for the authentication type of the access card as a unique identification number authentication type, when the fingerprint authentication of the fingerprint data of the cardholder and the fingerprint authentication of the preset fingerprint template data is successful, determining that the fingerprint identification state of the access card is the fingerprint authentication successful state; based on the authentication type of entrance guard card, carry out entrance guard authentication when entrance guard card and entrance guard equipment communication according to fingerprint identification state, include: determining the serial number of the access card according to the fingerprint identification state based on the authentication type of the access card; the access card serial number is written into the unique identification number register 15, so that when the access card is communicated with the access device, the access device reads the access card serial number from the unique identification number register 15, determines whether the access card serial number is matched with a preset unique identification number in the access device, and controls the door opening or refuses the door opening. Therefore, a fingerprint authentication mode of card serial number comparison can be adopted, and user authentication is facilitated.

The access card serial number is used for uniquely identifying the serial number of the access card. The access card serial number can be a preset unique access card serial number, and can be set according to user requirements or set by manufacturers.

As shown in fig. 2, the step 140 in the access authentication method provided in the embodiment of the present application may further include that the authentication type of the access card is a key authentication type, when the fingerprint identification state is a successful fingerprint authentication state, when the access card communicates with the access device, the access device receives data to be encrypted sent by the access device; encrypting the data to be encrypted by using a key of the access card to obtain ciphertext data; and transmitting ciphertext data to the access control equipment so that the access control equipment can determine whether the key of the access control card is consistent with the key of the access control equipment according to the ciphertext data and control the door opening or refusing to open the door. Thus, when the authentication type of the access card is the key authentication type, the security of the access card authentication is improved.

Referring to fig. 1, an access card 10 includes an energy storage power supply 13, where the energy storage power supply 13 is connected with a chip 11, and the embodiment of the application further includes that when a key is not pressed and the access card is placed in a non-access field, the chip does not work, and the energy storage power supply enters a charging state. The access card 10 includes a charging module 16 and a non-contact antenna 17 connected to the charging module 16, when the chip 11 is located in a non-contact charger, the non-contact antenna 17 receives energy of the non-contact charger, and charges the energy storage power supply 13 under the control of the charging module 16. And during the charging process, the chip 11 senses the non-receiving energy of the non-contact charger, but the chip 11 does not perform further communication because no related command is used for controlling the chip 11 to act. At this time, since the key is not pressed, the power supply control module 14 disconnects the energy storage power supply 13 to charge the chip 11, so that the energy storage power supply 13 is ensured not to discharge other circuits in the charging process. The safety of the circuit is improved.

In the embodiment, before the access control card communicates with the access control device, fingerprint authentication is performed on the cardholder and the preset fingerprint template data, at the moment, the compared preset fingerprint template data only has one person data, the compared data size is small, the time of fingerprint authentication of the cardholder in the communication process of the access control card and the access control device is reduced, the risk of communication failure caused by exceeding the timing duration is reduced, and the access control card is also convenient to use by an owner. And the independent fingerprint identification state is used for rapidly reflecting whether a cardholder is matched with the access card, so that the identification efficiency of whether the access card is matched with a person is improved, and the use safety of the access card is further improved.

Fig. 3 is a schematic diagram of a process for obtaining preset fingerprint template data in the access authentication method shown in fig. 2. As shown in fig. 3, the preset fingerprint template data is obtained by the following steps 210 to 260:

step 210, a fingerprint acquisition instruction is acquired.

Step 220, generating a starting signal according to the fingerprint acquisition instruction, so as to control the energizing time of the energy storage power supply according to the starting signal.

Step 230, detecting whether preset fingerprint template data exist in the access card within the power-on duration of the energy storage power supply, if yes, that is, detecting that preset fingerprint template data exist in the access card, and executing step 240. If not, that is, if the preset fingerprint template data does not exist in the access card, the fingerprint identification state is the state of not performing fingerprint authentication, and the access card can be used only by inputting the fingerprint template data, then step 250 and step 260 are executed.

Step 240, obtaining fingerprint data of a cardholder of the access card.

Step 250, obtain fingerprint template data for the cardholder.

The step 250 further includes obtaining fingerprint data of a predetermined number of times of the cardholder collected by the fingerprint collection module, and obtaining fingerprint template data according to the fingerprint data of the predetermined number of times. Therefore, fingerprint template data can be acquired through the fingerprint acquisition module, and the fingerprint template data can be acquired for a plurality of times to ensure the validity of the data. The predetermined number of times may be set according to the user's requirement, for example, the predetermined number of times is greater than 6 and less than 10. Alternatively, the predetermined number of times is equal to 8.

Step 260, storing the fingerprint template data as preset fingerprint template data. Therefore, if the preset fingerprint template data does not exist in the access control card in the power-on duration of the energy storage power supply, the fingerprint template data of the cardholder is obtained so as to obtain the preset fingerprint template data, and the follow-up comparison is convenient.

If the authentication type of the access card is the key authentication type, the access device acquires the access card serial number, and the access device determines whether the access card serial number is matched with a preset serial number in a preset database so as to control the door opening or refusing the door opening. And if the serial number of the access card is matched with the preset serial number in the preset database, the access equipment generates an access authentication success signal which is used for controlling the door to be opened. And if the access card serial number is not matched with the preset serial number, generating an access authentication failure signal by the access equipment, wherein the access authentication failure signal is used for refusing to open the door. Thus, the access control equipment does not need to collect fingerprints or authenticate fingerprints, and access control authentication can be rapidly performed through the serial number of the access control card.

In practical application, as shown in fig. 1, when a fingerprint acquisition instruction is acquired, a red LED lamp is turned on to prompt a cardholder to press a fingerprint. After the fingerprint acquisition module 12 obtains the fingerprint data of the cardholder, the red LED light is turned off, prompting the cardholder to remove the finger. When the fingerprint data of the cardholder are collected again, the red LED lamp is lighted again, and the cardholder is prompted to press the fingerprint. This is repeated until the predetermined number of times the fingerprint data is required to be acquired is completed.

In the embodiment of the application, a fingerprint template is acquired in the energizing time of the energy storage power supply, fingerprint template data are extracted, and preset fingerprint template data are obtained. And in the energizing time of the energy storage power supply, the normal power supply of the chip is ensured, and the normal communication between the chip and the fingerprint acquisition module is completed. And the preset fingerprint template data are input into the access control card in advance, and before the access control card is communicated with the access control equipment, the on-site fingerprint acquisition is required to be completed, the comparison with the fingerprint template is completed, the fingerprint authentication state identification is generated, and the subsequent authentication process of the access control equipment is executed.
