All the above alternatives, can form the alternative embodiment of the disclosure according to any combination, and the disclosure is real It applies example and this is no longer repeated one by one.

Fig. 3 is a kind of method flow diagram of fingerprint recognition shown according to an exemplary embodiment, and this method is applied to lock Shield in program, as shown in figure 3, the present embodiment will carry out expansion explanation to embodiment shown in Fig. 2.This method includes following step Suddenly.

In step 301, the third-party application of terminal is sent by callback interface between screen locking program to screen locking program Call instruction.

Due to the convenient, fast and safe feature of fingerprint recognition, more and more third-party applications are all integrated with fingerprint It identifies this function, and then completes the authentication of user by fingerprint recognition.When third-party application carries out fingerprint recognition, Need to obtain the fingerprint identification region of fingerprint module in face, and the function of unlocking terminal screen is often the included function of system, Fingerprint identification region usually can be got when unlocking terminal screen.Therefore, the embodiment of the present disclosure is arranged in screen locking program One callback interface, may be implemented the interaction namely third between third-party application and screen locking program by the callback interface Fang Yingyong can obtain the fingerprint identification region of fingerprint module in face based on the callback interface by screen locking program, and then realize Fingerprint recognition.

It should be noted that third-party application may include multiple interfaces, such as home interface and other specified functions pair The interface answered, therefore, third-party application can detecte whether be switched to the corresponding interface of fingerprint identification function.When third party answers With detect be switched to fingerprint identification function corresponding interface when, illustrate that third-party application may need to carry out fingerprint recognition, Third-party application can send call instruction to screen locking program by the callback interface between screen locking program at this time.Certainly, it uses Family may use the fingerprint identification function in third-party application more frequent, and therefore, third-party application can also detect Third-party application is opened to user, i.e., when third-party application is in home interface, the readjustment that will pass through between screen locking program is connect Mouth sends call instruction to screen locking program.The embodiment of the present disclosure sends the execution of call instruction to third-party application to screen locking program Opportunity is not construed as limiting.

Wherein, third-party application can be the application for needing to be verified to user identity using fingerprint identification function, example Such as, payment application.When third-party application be payment in application, third-party application can detect need by fingerprint recognition into When row payment, call instruction is sent to screen locking program, and then carry out the verifying of user identity.In addition, third-party application and screen locking Callback interface between program can be callback interface.

In step 302, screen locking program refers to when receiving the call instruction of third-party application transmission according to the calling It enables, opens fingerprint module in the face being integrated on terminal screen.

Screen locking program can determine at this time after the call instruction for receiving third-party application transmission by callback interface It needs to open fingerprint module in the face being integrated in terminal, therefore, screen locking program can pass through fingerprint mould in screen locking program and face Fingerprint module in the face is opened in interaction between block.In order to which just with description, the embodiment of the present disclosure answers screen locking program with third party Interface between is known as the first callback interface, and the interface between fingerprint module in screen locking program and face is known as the second readjustment and is connect Mouthful.Therefore, screen locking program receive third-party application transmission call instruction and determine need fingerprint module in opening face when, Fingerprint module in opening face can be controlled by the second callback interface.

It should be noted that screen locking program by the second callback interface control opening face in fingerprint module when, Ke Yigen Open command is generated according to the call instruction received, then which refers to the unlatching for fingerprint module in opening face Order is sent to fingerprint module in face, and fingerprint module, can fingerprint module in opening face when receiving the open command in face.

Further, it after interior fingerprint module is successfully opened face to face, can be sent by the second callback interface to screen locking program special Determine information, the specific information is for determining fingerprint module in the opening face that succeeded.Screen locking program when receiving the specific information, It can determine and successfully open fingerprint module in face,

Wherein, the second callback interface and the first callback interface can be the same interface, be also possible to different interfaces, this Open embodiment does not limit this.When the second callback interface and the first callback interface are the same interfaces, third-party application Pass through with fingerprint module in face and interacted between an interface and screen locking program, saves interface resource, and then save The resource that fingerprint recognition is consumed.When the second callback interface and the first callback interface are different interface, third-party application and It is interacted between screen locking program and interacts and can be carried out between fingerprint module in face and screen locking program simultaneously, improve friendship Mutual efficiency, and then improve the efficiency of fingerprint recognition.

In step 303, screen locking program determines whether the call instruction is used to unlock terminal screen, when the call instruction not When being for unlocking terminal screen, fingerprint identification region of the fingerprint module in terminal screen in acquisition face.

Since screen locking program and third-party application can call fingerprint module in face；Therefore, which may be Screen locking program oneself triggering, it is also possible to third-party application triggering.Also, the call instruction of screen locking program oneself triggering is used In unlock terminal screen, and the call instruction of third-party application triggering is for verifying user identity.Therefore, screen locking program The treatment mechanism for the call instruction that the call instruction triggered according to oneself is triggered with third-party application is different.Therefore, screen locking program When receiving call instruction, which can be parsed, determine the call instruction whether be oneself triggering tune With instruction；When the call instruction is the call instruction of oneself triggering, determine the call instruction for unlocking terminal screen；When this When call instruction is not the call instruction of oneself triggering namely the call instruction is the call instruction of third-party application triggering, really The fixed call instruction is not intended to unlock terminal screen.

In a kind of possible embodiment, the call instruction of screen locking program triggering can carry the mark of screen locking program；And the The call instruction of tripartite's applications trigger can carry the mark of third-party application.Namely screen locking program can be carried in the call instruction Mark or third-party application mark.Screen locking program can determine the call instruction according to the mark that the call instruction carries Whether the call instruction of oneself triggering, which can be with are as follows: screen locking program parses call instruction, then according to parsing Obtained mark judges that the call instruction is the tune of the call instruction by screen locking program oneself triggering or third-party application triggering With instruction.When the mark that parsing obtains is the mark of screen locking program, determine that the call instruction is triggered by screen locking program oneself Call instruction；When the instruction that parsing obtains is the mark of third-party application, determine that the call instruction is by third-party application The call instruction of triggering.For example, when third-party application is payment in application, can take in the call instruction that third-party application triggers Mark with payment.

It should be noted that being the call instruction of oneself triggering when screen locking program determines the call instruction not, that is, determine When the call instruction is not intended to unlock terminal screen, then it can determine that the call instruction is that the calling of third-party application triggering refers to It enables, illustrates that third-party application needs to obtain at this time fingerprint identification region by screen locking program, and then realize fingerprint recognition.Cause This, for screen locking program when determining that the call instruction is not intended to unlock terminal screen, fingerprint module is in terminal in available face Fingerprint identification region in screen.

Wherein, screen locking program can determine that whether the call instruction is used to unlock end panel when receiving call instruction Curtain, can also receive call instruction and according to the call instruction open in the face that is integrated on terminal screen fingerprint module it Afterwards, it then determines whether the call instruction is used to unlock terminal screen, call instruction can also received, and open and be integrated in end Determine whether the call instruction is used to unlock terminal screen, the embodiment of the present disclosure again while fingerprint module in face on the screen of end It does not limit this.Wherein, it if screen locking program is receiving call instruction, and is opening in the face being integrated on terminal screen It determines whether the call instruction is used to unlock terminal screen again while fingerprint module, fingerprint identification process can be saved and spent Time, improve the efficiency of fingerprint recognition.

It, can fingerprint mould in first receiving plane in addition, screen locking program is according to call instruction opening face after fingerprint module Fingerprint module in the specific information and the determining opening face that succeeded that block is sent, then determine whether the call instruction is used to unlock terminal Screen, can also first determine the call instruction whether be used to unlock fingerprint module in terminal screen, then receiving plane send it is specific Information simultaneously determines fingerprint module in the opening face that succeeded, can also the specific information of fingerprint module transmission and determination in receiving plane Succeeded fingerprint module in opening face while determine whether the call instruction is used to unlock terminal screen, the embodiment of the present disclosure pair This is without limitation.Wherein, if screen locking program in receiving plane fingerprint module send specific information and determination successfully open When determining whether the call instruction is used to unlock terminal screen while fingerprint module in face, fingerprint identification process institute can be saved The time of cost improves the efficiency of fingerprint recognition.

In step 304, screen locking program shows fingerprint icon at the fingerprint identification region of current interface, the fingerprint icon For prompting the finger of user to press in fingerprint identification region.

Since fingerprint module is arranged in terminal screen in face, user can not intuitively recognize which region of terminal screen It is the fingerprint identification region of fingerprint module in face, therefore, fingerprint identification area can be prompted the user with by fingerprint image target form The position in domain, and then complete fingerprint recognition.

In a kind of possible embodiment, the screen locking program fingerprint recognition of fingerprint module in terminal screen in acquisition face Behind region, one layer of locking screen interface can be superimposed in current interface, and show and refer at the fingerprint identification region of the locking screen interface Line icon.Due to being to show that fingerprint icon namely fingerprint icon can accurately reflect fingerprint recognition at fingerprint identification region The position in region, therefore, the finger of user touch the fingerprint icon and are equivalent to the finger of user at fingerprint identification region It is pressed, fingerprint identification function can be realized at this time, avoid fingerprint image marker tape to the misleading of user, therefore fingerprint recognition Effect it is preferable.

It should be noted that screen locking program can also carry out transparent processing, screen locking circle after transparent processing to locking screen interface Face is used to show the prompt information of third-party application through the locking screen interface.Optionally, screen locking program is superimposed in current interface After one layer of locking screen interface, transparent processing first can be carried out to the locking screen interface, then the finger of the locking screen interface after transparent processing Fingerprint icon is shown at line identification region；Fingerprint icon can also be first shown at the fingerprint identification region of locking screen interface, then Transparent processing is carried out to the locking screen interface after display fingerprint icon, the embodiment of the present disclosure does not limit this.Wherein, to display When locking screen interface after fingerprint icon carries out transparent processing, it can will show in the locking screen interface after fingerprint icon in addition to fingerprint image Region except mark carries out transparent processing.

Since the current interface of third-party application would generally show some prompt informations, such as when third-party application is payment In application, showing the prompt information of " fingerprint please be input, and carry out authentication by fingerprint to complete to pay " in current interface. Therefore, when current interface is superimposed one layer and includes fingerprint image target locking screen interface, the prompt in third-party application in order to prevent The locking screen interface that information is applied blocks, and the embodiment of the present disclosure has made transparent processing to the locking screen interface.In this way, user not only may be used Accurately to carry out fingerprint recognition, can also clearly check shown in the current interface of third-party application it is all in Hold, including prompt information.

It wherein, can also be at fingerprint identification region other than it can show fingerprint icon at fingerprint identification region Show fingerprint icon and fingerprint identification information；The fingerprint identification information is for prompting user to press user's at the fingerprint icon Finger.For example, showing the fingerprint recognition letter of fingerprint icon and " please pressing finger at fingerprint icon " at fingerprint identification region Breath.In this case, user can be through the region in the locking screen interface other than fingerprint icon and fingerprint identification information All the elements for checking third-party application, including prompt information.

In step 305, when screen locking Programmable detection fingerprint identification region is pressed by finger, the fingerprint identification region is obtained In the finger finger print information, and according to the finger print information carry out fingerprint recognition.

Due to showing fingerprint icon at fingerprint identification region, and user can prompt to incite somebody to action according to the fingerprint image target Finger is pressed at the fingerprint identification region, and therefore, it is to be pressed by region by finger that screen locking program, which can detecte fingerprint, And the finger print information of finger at the hand fingerprint identification region is obtained, and then fingerprint recognition is carried out according to the finger print information.Below will Step 305 is described in detail by step (1), (2) and (3):

(1) screen locking program detects fingerprint identification region.

Screen locking program can detect fingerprint identification region, and when detect that the fingerprint identification region is pressed by When pressure event, the event type and pressure value of the press event are obtained, when the event type is specified type, and the pressure value is super When crossing preset threshold, determine that the fingerprint identification region is pressed by finger.Wherein, specified type is the corresponding event class of fingerprint recognition Type.

In a kind of possible embodiment, screen locking program can also be examined fingerprint identification region by pressure sensor It surveys.It that is to say, screen locking program can send acquisition instructions to pressure sensor, and pressure sensor is receiving the acquisition instructions Afterwards, fingerprint identification region can be detected.When pressure sensor detects the pressing thing that the fingerprint identification region is pressed When part, the event type and pressure value of the press event are determined, and report the event type and the pressure value to screen locking program.Lock Shield program in the event type and pressure value for receiving the press event, and works as the event type for specified type, and the pressure When value is more than preset threshold, determine that the fingerprint identification region is pressed by finger.

Wherein, pressure sensor, can during detecting after receiving the acquisition instructions to fingerprint identification region First to detect whether to receive the location information of the finger of touch sensible module transmission, when receiving the location information of finger, Fingerprint identification region is detected, and determines whether the finger is located at fingerprint identification region according to the location information of finger.When When pressure sensor determines that the finger is located at fingerprint identification region, the pressing that the fingerprint identification region is pressed has been confirmly detected Event.

Since user may accidentally touch fingerprint identification region, and generally accidentally the pressure value of touching is usually all smaller, therefore, in order to The event that user is accidentally touched to fingerprint identification region is avoided to need to press the pressing of fingerprint identification region when fingerprint recognition as user Specified type and preset threshold can be set in event, the embodiment of the present disclosure, only when the event type of press event is specified class When type and pressure value are more than preset threshold, just the determination fingerprint identification region is pressed by finger, improves the efficiency of fingerprint recognition.
