Detailed Description

For purposes of clarity in describing the embodiments of the present application, the words "exemplary" or "such as" are used herein to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "for example" should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.

In the embodiments of the present application, "at least one" means one or more, and "a plurality" means two or more. "and/or", describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate: a alone, a and B together, and B alone, wherein a, B may be singular or plural. The character "/" generally indicates that the context-dependent object is an "or" relationship. "at least one of" or the like means any combination of these items, including any combination of single item(s) or plural items(s). For example, at least one (one) of a, b, or c may represent: a, b, c, a-b, a-c, b-c, or a-b-c, wherein a, b, c may be single or plural.

It should be noted that "at … …" in the embodiment of the present application may be an instant when a certain situation occurs, or may be a period of time after a certain situation occurs, which is not particularly limited in the embodiment of the present application. In addition, the display interface provided by the embodiment of the application is only used as an example, and the display interface can also comprise more or less contents.

In a possible implementation, when the terminal device is unlocked by using the ultrasonic fingerprint, the terminal device may possibly fail to unlock the screen, so that the use experience of the user is affected.

This is because the terminal device may be stopped from listening to the fingerprint or cancel listening to the fingerprint while in a state of listening to the fingerprint. When the terminal equipment reinitiates the fingerprint monitoring process, the terminal equipment can judge whether the fingerprint unlocking parameter of the terminal equipment meets the condition of updating the fingerprint state. In a possible implementation, the fingerprint unlocking parameter may not meet the condition of updating the fingerprint state due to the fact that the distance between the fingerprint unlocking icon and the ultrasonic fingerprint unlocking module is far when the terminal device initiates monitoring on the password input interface. The terminal equipment does not successfully initiate the fingerprint monitoring flow and can not update the fingerprint state into the state of monitoring the fingerprint. The terminal device is not able to recognize the user's fingerprint nor verify the fingerprint and unlock the screen.

In view of the above, the embodiment of the application provides a fingerprint unlocking method, which is implemented by adding a flag bit of a first button; when the first button is clicked, the terminal device sets the flag bit of the first button to a second value; when the flag bit of the first button is set to the second value, the terminal equipment can execute the fingerprint monitoring process. In this way, the terminal device can successfully update the fingerprint state to the state of monitoring the fingerprint, so that the terminal device can recognize and verify the user fingerprint later, and the unlocking screen is realized.

In the embodiment of the present application, the terminal device may also be referred to as a terminal (terminal), a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), and so on. The terminal device may be a mobile phone, a smart television, a wearable device, a tablet (Pad), a computer with wireless transceiving function, a Virtual Reality (VR) terminal device, an augmented reality (augmented reality, AR) terminal device, a wireless terminal in industrial control (industrial control), a wireless terminal in unmanned driving (self-driving), a wireless terminal in teleoperation (remote medical surgery), a wireless terminal in smart grid (SMART GRID), a wireless terminal in transportation security (transportation safety), a wireless terminal in smart city (SMART CITY), a wireless terminal in smart home (smart home), or the like.

A scenario of fingerprint unlocking in a possible implementation is described in connection with fig. 3. Fig. 3 shows an interface schematic of optical fingerprint unlocking and an interface schematic of ultrasonic fingerprint unlocking. As shown in fig. 3:

Illustratively, the interface shown in a in fig. 3 to the interface shown in c in fig. 3 illustrate a scenario in which an optical fingerprint is unlocked. In the interface shown in a of fig. 3, the terminal device displays a lock screen interface, which includes a fingerprint acquisition area identifier 301. In one possible implementation, when the terminal device identifies the user fingerprint in the fingerprint acquisition area, the terminal device acquires the user fingerprint information and compares the user fingerprint information with the pre-entered fingerprint, and after verification is successful, the terminal device can display the interface shown as c in fig. 3. The interface shown in c in fig. 3 may be an unlocked desktop.

In another possible implementation, in the interface shown in a in fig. 3, when the terminal device receives a slide-up operation, the terminal device may enter the interface shown in b in fig. 3. The interface shown in b in fig. 3 displays a fingerprint acquisition area identifier 302, a password input area, a keyboard, and the like. In the interface shown in b in fig. 3, the user may choose to unlock the screen using both password unlocking and fingerprint unlocking. When the terminal device receives a trigger operation for the fingerprint acquisition area identifier 302, the terminal device may also display the interface shown in c in fig. 3.

Illustratively, the interface shown as d in fig. 3 to the interface shown as g in fig. 3 illustrate one scenario of ultrasonic fingerprint unlocking.

In the interface shown in d of fig. 3, the terminal device displays a lock screen interface, which includes the fingerprint acquisition area identifier 303. In a possible implementation, when the terminal device receives a trigger operation for the fingerprint acquisition area identifier 303, the terminal device displays the interface shown in g in fig. 3. The interface shown in g in fig. 3 is the unlocked desktop.

In another possible implementation, in the interface shown in d in fig. 3, when the terminal device receives a slide-up operation, the terminal device may enter a password input interface, such as the interface shown in e in fig. 3. The interface shown in e in fig. 3 displays a first button 304, a password input area, a keyboard, etc., wherein the fingerprint acquisition area identifier 303 and the first button 304 may have the same style, and the icon specification of the first button 304 is smaller than the identifier specification of the fingerprint acquisition area identifier 303. In the interface shown in e in fig. 3, the user may choose to unlock the screen using password unlocking. When the terminal device receives a trigger operation for the first button 304, the terminal device displays a fingerprint authentication interface, such as the interface shown as f in fig. 3. The interface shown by f in fig. 3 displays a fingerprint collection area identifier 305, a prompt text 306 and a cancel unlock button 307, where the identifier specification of the fingerprint collection area identifier 305 is consistent with the identifier specification of the fingerprint collection area identifier 303 and is greater than the icon specification of the first button 304. When the terminal device receives a trigger operation for the fingerprint acquisition area identification 305, the terminal device may unlock the screen and display the interface shown at g in fig. 3.

It will be appreciated that the terminal device may use an ultrasonic fingerprint unlocking module to collect the user's fingerprint, and in some scenarios, the ultrasonic fingerprint unlocking module may be disposed in the middle and lower part of the terminal device, for example, the ultrasonic fingerprint unlocking module may correspond to the display position of the fingerprint collection area identifier 303 in the interface shown in d in fig. 3. Thus, when a finger of a user is placed in the area displayed by the fingerprint collection area identifier 303, the ultrasonic fingerprint unlocking module below the area can collect fingerprint information of the user.

In the interface e shown in fig. 3, if the terminal device can support both password unlocking and fingerprint unlocking, the keyboard and the fingerprint acquisition area identifier in the interface e shown in fig. 3 will overlap, which affects the use of the terminal device. Therefore, in order to improve the aesthetic property and reduce false triggering after the two functional icons are overlapped, the terminal device may be provided with the first button. The interface shown as e in fig. 3 shows a first button 304 which the terminal device can use to invoke the interface shown as f in fig. 3.

The fingerprint acquisition area identification 305 in the interface shown as f in fig. 3 coincides with the location of the fingerprint acquisition area identification 303 in the interface shown as d in fig. 3. The user can place the finger in the region that fingerprint collection region sign 305 shows, and when terminal equipment received the trigger operation to fingerprint collection region sign 305, terminal equipment can use ultrasonic wave fingerprint unlocking module to gather user's fingerprint information and accomplish the fingerprint unblock.

It should be noted that, in general, the terminal device may support optical fingerprint unlocking or ultrasonic fingerprint unlocking; the terminal device may display the interface shown as a in fig. 3 or the interface shown as d in fig. 3. The embodiment of the application compares the optical fingerprint unlocking process with the ultrasonic fingerprint unlocking process, and aims to illustrate that when the terminal equipment uses the ultrasonic fingerprint for unlocking, an interface f shown in fig. 3 possibly appears, and the meaning of simultaneously using the optical fingerprint unlocking and the ultrasonic fingerprint unlocking in the terminal equipment is not provided.

A scenario in which the terminal device uses the ultrasonic fingerprint unlock screen in the embodiment of the present application will be described with reference to fig. 4 to 6. Fig. 4 is an interface schematic diagram of a fingerprint unlocking method according to an embodiment of the present application, where the interface schematic diagram is shown in fig. 4:

The interface a shown in fig. 4 can be displayed after the terminal equipment is on the screen, and the interface a shown in fig. 4 comprises a fingerprint acquisition area identifier 401 and a camera application icon 402; wherein, fingerprint acquisition area identifier 401 can be used to characterize the area where the ultrasonic fingerprint unlocking module can identify the fingerprint. The terminal device may pull up the camera application based on the camera application icon 402. Illustratively, when the terminal device receives a press operation (interface shown as a in fig. 4) and an upward drag operation (interface shown as b in fig. 4) for the camera application icon 402, the terminal device may launch the camera application and display the interface shown as c in fig. 4.

The interface shown in c in fig. 4 includes a photographing button, gallery application icon 403, and the like. In one possible implementation, the terminal device may view the photograph. When the terminal device receives a trigger operation for the gallery application icon 403, the terminal device enters the interface shown as d in fig. 4. In the interface shown as d in fig. 4, the terminal device may display gallery application icon 404.

It will be appreciated that the gallery application icon 404 may be used by the terminal device to launch the gallery application, but when the terminal device is in an unlocked state, the terminal device needs to be unlocked to be able to continue accessing the gallery application. For example, when the terminal device receives a trigger operation for gallery application icon 404, the terminal device may display the interface shown as e in fig. 4. The interface shown by e in fig. 4 may be a password input interface, and the terminal device displays a first button 405; the first button is used for indicating the terminal equipment to enter the fingerprint verification interface.

In the interface shown as e in fig. 4, the user can enter a password or unlock it by a fingerprint. For example, when the terminal device receives a trigger operation for the first button 405, the terminal device may display an interface shown by f in fig. 4. In the interface shown at f in fig. 4, the terminal device displays a fingerprint acquisition area identifier 406. At this point, the user may place a finger in the fingerprint acquisition area. The terminal equipment can collect user fingerprints, compares the collected fingerprints with pre-recorded fingerprint information, and can unlock the screen after verification is passed. For example, when the terminal device receives the triggering operation for the fingerprint acquisition area identifier 406, the terminal device displays an interface shown by g in fig. 4, where the interface shown by g in fig. 4 may be an interface when the terminal device runs a gallery application in the foreground.

In the above scenario, the terminal device may pull up the lock screen application based on the camera application, and then the terminal device may unlock the screen using the fingerprint to display the picture in the gallery application. Another scenario applicable to the fingerprint unlocking method provided by the embodiment of the present application is as follows with reference to fig. 5. Fig. 5 shows an interface schematic diagram of a fingerprint unlocking screen according to an embodiment of the present application, as shown in fig. 5:

The interface a shown in fig. 5 can be displayed after the terminal device is on the screen. In some embodiments, the terminal device in the locked state may provide a function of quickly starting the application, and illustratively, when the terminal device receives a trigger operation of sliding up from the bottom of the screen, the terminal device may display the interface shown in b in fig. 5. The interface shown in b in fig. 5 shows a shortcut operation panel 501, and the shortcut operation panel 501 may include a sound recording application icon 502, a calculator icon 503, a flashlight icon 504, a clock icon 505, and the like. The terminal device may customize the application in the shortcut operation panel 501, which is not limited in this embodiment of the present application.

Taking the recording application in the shortcut operation panel 501 as an example, when the terminal device receives a trigger operation for the recording application icon 502, the terminal device may start the recording application and display the interface shown in c in fig. 5. The interface shown in c in fig. 5 includes a record button 506, and when the terminal device receives a trigger operation for the record button 506, the terminal device starts recording audio, and the audio recording interface is shown as interface d in fig. 5. In the interface shown in d in fig. 5, the terminal device may terminate recording using the stop recording button 507, for example, when the terminal device receives a trigger operation for the stop recording button 507, the terminal device stops recording and saves the already recorded audio.

It can be appreciated that the user can view the recorded audio after finishing recording the audio, but when the terminal device is in an unlocked state, the terminal device needs to unlock the screen first to view the audio file. For example, when the terminal device receives a trigger operation for the stop record button 507, the terminal device displays an interface shown as e in fig. 5, and the user can unlock the terminal device using password unlocking or fingerprint unlocking. Taking fingerprint unlocking as an example, when the terminal device receives a trigger operation for the first button 508, the terminal device enters the interface shown by f in fig. 5. In the interface shown at f in fig. 5, the terminal device displays a fingerprint acquisition area identifier 509.

At this point, the user may place a finger in the fingerprint acquisition area. The terminal equipment can collect user fingerprints, compares the collected fingerprints with pre-recorded fingerprint information, and can unlock the screen after verification is passed. For example, when the terminal device receives a trigger operation for the fingerprint acquisition area identifier 509, the terminal device displays an interface shown by g in fig. 5, where the interface shown by g in fig. 5 may display a recorded audio file.

In the above scenario, the terminal device may pull up the recording application based on the shortcut operation panel, and when the terminal device finishes recording, the recording application may pull up the screen locking application, and the terminal device may unlock the screen in the screen locking application by using the user fingerprint to display the recording file in the recording application. Another scenario applicable to the fingerprint unlocking method provided by the embodiment of the present application is as follows with reference to fig. 6. Fig. 6 shows an interface schematic diagram of a fingerprint unlocking screen according to an embodiment of the present application, as shown in fig. 6:

After the terminal device is on, a screen locking interface can be displayed, such as an interface shown as a in fig. 6. When the terminal device receives the slide-up operation, the terminal device may display a password input interface, such as the interface shown as b in fig. 6. The interface shown in b in fig. 6 shows a first button 601, and when the terminal device receives a trigger operation for the first button 601, the terminal device may enter a fingerprint authentication interface, such as the interface shown in c in fig. 6. In the interface shown in c in fig. 6, the terminal device is displayed with a fingerprint acquisition area identification 602 and a cancel unlock button 603. At this time, the user may not wish to unlock the screen or click by mistake to cancel the unlocking, for example: when the terminal device receives a trigger operation for canceling the unlock button 603, the terminal device returns to the password input interface, as indicated by d in fig. 6. When the user wants to unlock using the fingerprint, the user may click on the first button 604 in the interface shown in d in fig. 6, and in response to a trigger operation for the first button 604, the terminal device may reenter the fingerprint authentication interface, such as the interface shown in e in fig. 6.

In the interface shown as e in fig. 6, the terminal device displays a fingerprint acquisition area identifier 605. At this point, the user may place a finger in the fingerprint acquisition area. The terminal equipment can collect user fingerprints, compares the collected fingerprints with pre-recorded fingerprint information, and can unlock the screen after verification is passed. For example, when the terminal device receives a trigger operation for the fingerprint acquisition area identifier 605, the terminal device displays an interface f shown in fig. 6, where the interface f shown in fig. 6 may be a desktop.

It should be noted that, in the embodiment of the present application, taking the case that the foreground of the terminal device does not run other application programs as an example, after the screen is unlocked, the terminal device displays the interface f shown in fig. 6; when the application program, such as a social application, is running in the foreground of the terminal device, the chat interface can be displayed by the terminal device after the terminal device unlocks the screen. The embodiment of the application does not limit the interface shown by f in fig. 6.

It can be understood that, the above embodiments are described in connection with fig. 4 to fig. 6 for a scenario where the fingerprint unlocking method provided by the embodiment of the present application is applicable, but the interface is not limited to the embodiment of the present application.

The fingerprint unlocking method provided by the embodiment of the application is described in detail below with reference to the accompanying drawings. It should be noted that "at … …" in the embodiment of the present application may be an instant when a certain situation occurs, or may be a period of time after a certain situation occurs, which is not particularly limited in the embodiment of the present application.

The fingerprint unlocking method provided by the embodiment of the application is described with reference to fig. 7. Fig. 7 shows a flowchart of a fingerprint unlocking method according to an embodiment of the present application. As shown in fig. 7:

in an exemplary embodiment, at S701, at a first moment, a first application is running in a foreground of a terminal device, the terminal device is in an unlocked state, and a fingerprint state of the terminal device is a first fingerprint state.

The first application may be an application program installed in the terminal device, the first application being different from the lock screen application. The first application may comprise a camera application. The terminal device is in an unlocked state, which can be understood as: the terminal equipment is preset with fingerprint unlocking; at a first moment, the terminal device does not unlock the screen, and the terminal device only uses part of the functions of the first application.

The fingerprint state of the terminal device may be a fingerprint running state (FINGERPRINT RUNNING STATE), and the fingerprint state may be set as a first fingerprint state, a second fingerprint state, and a third fingerprint state; the first fingerprint state can be used for indicating that the terminal equipment is in a state of not monitoring fingerprints, the second fingerprint state is used for indicating that the terminal equipment is in a state of monitoring fingerprints, and the third fingerprint state is used for indicating that the terminal equipment is in a state of not monitoring fingerprints. For example, the first fingerprint state may be fingerprint state stop (fingerprint_state_stop), the second fingerprint state may be fingerprint state run (fingerprint_state_running), and the third fingerprint state may be fingerprint state cancel (fingerprint_state_cancel).

It will be appreciated that, as shown in the scenario of fig. 4, the first application may be a camera application, and the terminal device foreground running with the first application may correspond to the scenario shown in c in fig. 4 or the scenario shown in d in fig. 4.

S702, at a second moment, the first application pulls up the screen locking application, and the terminal equipment displays a first interface; the first interface comprises a password input interface provided by the screen locking application and a first button, and a flag bit of the first button is a first value; the second time is later than the first time.

The screen locking application may be Keyguard; the first interface may be a password input interface, and the first interface may correspond to the interface shown as e in fig. 4; the password entry interface may be bouncer interface. The first interface includes a first button therein, which may correspond to the first button 405 in the interface shown as e in fig. 4.

The terminal equipment is pre-added with a zone bit of a first button, wherein the zone bit of the first button can be a first value or a second value; the first value is used for indicating that the terminal equipment does not execute the fingerprint monitoring process; the second value is used to indicate that the terminal device executes the listening fingerprint procedure. In one possible implementation, the first value may be False and the second value may be True; in another possible implementation, the first value may be 0 and the second value may be 1. The embodiment of the application does not limit the values of the first value and the second value, and the first value and the second value can also be other values which can be used for indicating whether the terminal equipment executes the monitoring fingerprint flow.

The terminal device may pull up the lock screen application using the first application. After the terminal equipment starts the screen locking application, the terminal equipment displays a password input interface, and the flag bit of the first button is a first value.

It can be understood that, at the second moment, the terminal device is in an unlocked state and the terminal device does not execute the fingerprint monitoring process, at this moment, the terminal device can input a password unlocking screen in the password input interface, but the terminal device cannot pass through the fingerprint unlocking screen in the password input interface.

S703, at a third moment, the terminal equipment receives a triggering operation for a first button, wherein a flag bit of the first button is a second value; the second value is different from the first value; the third time is later than the second time.

The trigger operation for the first button may be a trigger operation of clicking the first button 405 in the interface shown as e in fig. 4.

The terminal device may set the flag bit of the first button to the second value when receiving a trigger operation for the first button. The second value is used to indicate that the terminal device executes the listening fingerprint procedure. In one possible implementation, the flag bit of the first button may be clicking the first button (CLICK SMALL FINGERPRINT), and CLICK SMALL FINGERPRINT is assigned True when the terminal device receives a trigger operation for the first button.

S704, at a fourth moment, responding to the triggering operation of the first button, displaying a second interface by the terminal equipment, wherein the second interface comprises a fingerprint acquisition area identifier, the distance between the fingerprint acquisition area identifier and the ultrasonic fingerprint unlocking module is smaller than a first threshold value, and setting the fingerprint state to be a second fingerprint state by the terminal equipment; the second fingerprint state is used for indicating that the terminal equipment is in a state of monitoring fingerprints, and the fourth moment is later than the third moment.

The second interface may correspond to the interface shown as f in fig. 4. The fingerprint acquisition region identification may correspond to the fingerprint acquisition region identification 406 in the interface shown as f in fig. 4. The first threshold may be a preset value, and the first threshold is used for determining whether the fingerprint acquisition area identifier is within a range in which the ultrasonic fingerprint unlocking module can ultrasonically identify the fingerprint.

The terminal device sets the fingerprint state to the second fingerprint state, which can be understood as: the terminal device executes a process of starting to monitor fingerprints (START LISTENING For Fingerprint). The terminal equipment is in a state of monitoring fingerprints, and can monitor whether the terminal equipment receives the pressing operation of a user or not within the coverage range of the fingerprint acquisition area identifier. And subsequently, when the user places the finger in the coverage area of the fingerprint collecting area identifier, the ultrasonic fingerprint unlocking module can identify the user fingerprint in the fingerprint collecting area identifier and verify the user fingerprint. If the verification is passed, the terminal equipment is in an unlocking state; if the verification is not passed, the terminal device still keeps the unlocked state, and the terminal device can prompt the user to perform fingerprint verification again.

According to the fingerprint unlocking method provided by the embodiment of the application, the foreground of the terminal equipment is operated with the first application at the first moment, and the terminal equipment is in an unlocking state; the fingerprint state of the terminal equipment is a first fingerprint state; at a second moment, the first application pulls up the screen locking application, the terminal equipment displays a first interface, the first interface comprises a password input interface provided by the screen locking application and a first button, and a flag bit of the first button is a first value; at a third moment, the terminal equipment receives triggering operation aiming at a first button, and the zone bit of the first button is a second value; the second value is different from the first value; at a fourth moment, responding to the triggering operation of the first button, displaying a second interface by the terminal equipment, wherein the second interface comprises a fingerprint acquisition area identifier, the distance between the fingerprint acquisition area identifier and the ultrasonic fingerprint unlocking module is smaller than a first threshold value, and setting the fingerprint state to be a second fingerprint state by the terminal equipment. In this way, the terminal device may perform a listening fingerprint procedure when the flag bit of the first button is the first value, and the terminal device may unlock the screen using the fingerprint.

S705, at a fifth moment, the terminal equipment restores the zone bit of the first button to a first value; the fifth moment is later than the fourth moment.

In a possible implementation manner, the terminal device may restore to the first value when the fingerprint state is not the second fingerprint state; for example: CLICK SMALL FINGERPRINT is assigned to False.

In another possible implementation manner, the terminal device may determine whether to execute the listening procedure based on a preset condition, and the terminal device may set the flag bit of the first button to the first value after the determination is completed. For example: CLICK SMALL FINGERPRINT is assigned to False. The preset conditions and the determination process will be described in detail later in the embodiments of the present application, and will not be described here in detail.

According to the fingerprint unlocking method provided by the embodiment of the application, the terminal equipment restores the zone bit of the first button to the first value at the fifth moment. Therefore, when the terminal equipment receives the triggering operation for the first button next time, the terminal equipment can update the zone bit of the first button to the second value, so that the accuracy of the fingerprint unlocking method is improved.

Alternatively, the following describes steps S701-S704 with reference to the scenario shown in fig. 4, with the first application being a camera application.

The terminal device displays a screen lock interface, which includes a start button of the camera application. For example, the terminal device displays an interface shown in a in fig. 4, which includes a camera application icon 402 in fig. 4.

When the terminal device receives a trigger operation of a start button for the camera application, the terminal device starts the camera application. For example, the terminal device receives a trigger operation for the camera application icon 402, and in response to the trigger operation, the terminal device starts the camera application.

At a first moment, a camera application is operated at a foreground of the terminal equipment, the terminal equipment displays a third interface, and the third interface comprises a second button which is used for starting a gallery application; the fingerprint state of the terminal device is a first fingerprint state. For example, the third interface is the interface shown as d in fig. 4, where the interface shown as d in fig. 4 includes the gallery application icon 404, and the fingerprint state is fingerprint_state_stop.

At a second moment, the terminal equipment receives triggering operation aiming at a second button, and the camera application pulls up the screen locking application; the terminal device displays a first interface, and the flag bit of the first button is a first value. For example, the terminal device receives a trigger operation for the gallery application icon 404 in the interface shown in d in fig. 4, and the terminal device starts the lock screen application and enters the interface shown in e in fig. 4. The interface shown as e in fig. 4 includes a first button with a flag bit False.

At a third moment, the terminal device receives a triggering operation for the first button, and the flag bit of the first button is a second value. For example, in the interface shown in e of fig. 4, the terminal device receives a trigger operation for the first button 405, and the flag bit of the first button is True.

At a fourth time, in response to the triggering operation of the first button, the terminal device displays a second interface, and the terminal device sets the fingerprint state to a second fingerprint state. For example, in response to a trigger operation for the first button 405 in the interface shown as e in fig. 4, the terminal device enters the interface shown as f in fig. 4. The interface shown at f in fig. 4 includes a fingerprint acquisition region identifier 406, with a fingerprint state of fingerprint_state_running.

And when the ultrasonic fingerprint unlocking module identifies the fingerprint in the fingerprint acquisition area of the second interface and the verification is successful, the terminal equipment starts the gallery application. For example, in the interface shown by f in fig. 4, when the terminal device identifies a fingerprint in the fingerprint acquisition area and verifies the fingerprint successfully, the terminal device enters the interface shown by g in fig. 4, and the interface shown by g in fig. 4 may be an interface with a gallery application running in the foreground.

In order to facilitate understanding of the fingerprint unlocking method provided by the embodiment of the present application, the fingerprint unlocking method in the embodiment of the present application is described in detail below with reference to fig. 4, and fig. 8 shows a flow chart of the fingerprint unlocking method provided by the embodiment of the present application. As shown in fig. 8:

Exemplary, S801, the terminal device is on screen.

The terminal equipment is preset with fingerprint unlocking. When the terminal device is on the screen, the terminal device may receive a screen-on message, which may be onScreenTurningOn messages.

S802, displaying a screen locking interface by the terminal equipment, wherein the fingerprint state of the terminal equipment is a second fingerprint state.

The lock screen interface may be a notification unlock (notification keyguard) interface. The screen locking interface may correspond to the interface a shown in fig. 4, where the fingerprint state of the terminal device is a second fingerprint state, and may be: FINGERPRINT RUNNING STATE is finger print_state_running.

The terminal equipment can pull up the screen locking application after the screen is lightened. The terminal equipment displays a screen locking interface of the screen locking application, the screen locking interface comprises a fingerprint acquisition area identifier, the terminal equipment is in a state of monitoring fingerprints, and at the moment, the terminal equipment can unlock the screen based on the fingerprint acquisition area identifier.

In one possible implementation, the terminal device may launch the first application when the terminal device is in an unlocked state. For example, the terminal device may launch a first application based on the camera application icon 402 at an interface as shown in a in fig. 4.

S803, when the terminal equipment starts the first application, the terminal equipment updates the fingerprint state into a first fingerprint state.

It can be understood that the terminal device starts the first application, the first application is running in the foreground of the terminal device, the fingerprint state of the terminal device is the first fingerprint state, and the terminal device stops monitoring the fingerprint. For example, when the terminal device runs the first application, the terminal device sets FINGERPRINT RUNNING STATE to finger print_state_stop. At this time, the terminal equipment can not monitor the fingerprint, also can not use ultrasonic fingerprint unblock module to gather the fingerprint.

S804, the terminal equipment displays the first interface.

The first interface may correspond to the interface shown as e in fig. 4, and a first button may be included in the first interface. In a possible implementation, when the foreground of the terminal device runs the first application, the terminal device may display an interface as shown in c in fig. 4 or an interface as shown in d in fig. 4. When the terminal device receives a triggering operation for the gallery application icon 404 in the interface shown in d in fig. 4, the terminal device may pull up the lock screen application using the first application, and the terminal device displays the first interface with the flag bit of the first button as the first value.

S805, when the terminal device receives a trigger operation for the first button, the terminal device sets a flag bit of the first button to a second value.

When the user clicks the first button, the terminal device sets the flag bit of the first button to a second value in response to the clicking operation of the user. For example, the first button may have a flag bit of CLICKSMALLFINGERPRINT (TRUE) as the second value.

It should be noted that, when the terminal device receives the triggering operation for the first button, the terminal device may initiate monitoring the fingerprint, and the terminal device may update the fingerprint state to the second fingerprint state when the fingerprint unlocking parameter satisfies the preset condition. The preset condition may be related to a position where the terminal device supports fingerprint unlocking, an interface displayed by the terminal device, a distance between the first button and the ultrasonic fingerprint unlocking module, and/or a value of a flag bit of the first button.

And when the fingerprint unlocking parameters of the terminal equipment meet the preset conditions, the screen locking application sets the fingerprint state to be a second fingerprint state. Specifically, as shown in steps S806 to S809:

s806, the screen locking application judges whether the position of the terminal equipment supporting fingerprint unlocking is in the screen.

The location where the terminal device supports fingerprint unlocking may include on-screen, sideways, back, etc. In one possible implementation, a lock screen utility (Keyguard Utils) of a lock screen application may obtain a location where a terminal device supports fingerprint unlocking. The lock screen application determines whether the location where the terminal device supports fingerprint unlocking is in-screen (under dispiay, UD, also referred to as under-screen).

When the location where the terminal device supports fingerprint unlocking is in the screen, the terminal device may perform step S807.

S807, the screen locking application judges whether the interface displayed by the terminal equipment is a password input interface.

A screen-lock update listener (Keyguard Update Monitor) of the screen-lock application may determine an interface of the screen-lock application displayed by the terminal device. The lock screen application may include a lock screen interface, a password entry interface, and a fingerprint verification interface. The first interface is a password input interface.

In one possible implementation, the mbouncer value of the password entry interface is a third value and the mbouncer value of the lock screen interface is a fourth value. The lock screen application may determine the displayed interface based on mbouncer values. For example, the third value may be True and the fourth value may be False; the third value may also be 1 and the fourth value may be 0. The embodiment of the application does not limit the values of the third value and the fourth value.

When the interface displayed by the terminal device is a password input interface (for example, mbouncer values of the interface displayed by the terminal device are True), the terminal device may determine whether the position of the first button in the first interface is within a range in which the fingerprint can be identified by the ultrasonic fingerprint unlocking module, as shown in step S808.

S808, the screen locking application judges whether the distance between the first button and the ultrasonic fingerprint unlocking module is smaller than a first threshold value.

The first threshold is used for determining whether the fingerprint acquisition area is within the range of the ultrasonic fingerprint unlocking module capable of identifying fingerprints in an ultrasonic mode, for example, the first threshold can be 0.38, and the value of the first threshold is not limited in the embodiment of the application.

It will be appreciated that the first button is similar to the fingerprint capture area identification, but that the terminal device will not capture a user fingerprint at the first button when a user finger is placed on the first button. The finger view assistant (FINGER VIEW HELPER) of the screen locking application can acquire the distance between the first button and the ultrasonic fingerprint unlocking module and determine that the distance between the first button and the ultrasonic fingerprint unlocking module is greater than or equal to a first threshold.

The distance between the first button and the ultrasonic fingerprint unlocking module is greater than or equal to a first threshold, and the terminal device may execute step S809.

S809, the screen locking application judges whether the flag bit of the first button is a second value.

In one possible implementation, the flag bit of the first button is a second value, e.g., CLICK SMALL FINGERPRINT is True. The terminal device may set the fingerprint state to a second fingerprint state as shown in step S810.

S810, the terminal equipment sets the fingerprint state to be a second fingerprint state.

When the Fingerprint unlock parameter of the terminal device satisfies the preset condition, the terminal device may perform a procedure of starting to monitor the Fingerprint (START LISTENING For Fingerprint), set the Fingerprint state to the second Fingerprint state, for example, the terminal device may set the Fingerprint state to fingerprint_state_running through SET FINGERPRINT running state ().

In step S805, the terminal device receives a trigger operation for the first button. After the screen locking application performs the determining process of steps S806-S809, the terminal device may display the second interface of the screen locking application in response to the triggering operation for the first button. For example, the terminal device may display the interface shown by f in fig. 4, and the terminal device is in a state of listening to the fingerprint.

Alternatively, in a possible implementation manner, after the terminal device completes step S809, the terminal device may restore the flag bit of the first button to the first value.

The embodiment of the application takes the case that the preset condition is related to the position of the terminal equipment supporting fingerprint unlocking, the interface displayed by the terminal equipment, the distance between the first button and the ultrasonic fingerprint unlocking module and the value of the marker bit of the first button as an example, and describes the fingerprint unlocking method in the embodiment of the application. Embodiments of the present application may also use one or more of the conditions described above to determine whether to perform a snoop fingerprint procedure, as embodiments of the present application are not limited in this respect.

The above embodiment describes the fingerprint unlocking method in the embodiment of the present application by taking the scenario shown in fig. 4 as an example. The fingerprint unlocking method provided by the embodiment of the application is described below with a scene shown in fig. 5.

The step S901 is that, at a sixth moment, the terminal device displays a fourth interface, where the fourth interface includes a fingerprint collection area identifier; the fingerprint state is a second fingerprint state.

The fourth interface may be a lock screen interface, such as the interface shown as a in fig. 5. The interface shown as a in fig. 5 includes a fingerprint acquisition area identification. The fingerprint state of the terminal device is fingerprint_state_running.

When the terminal equipment displays the lock screen interface, fingerprint monitoring is initiated, and the fingerprint state is updated to be the second fingerprint state. The second fingerprint state may be understood as: the terminal device may identify a user fingerprint of the fingerprint acquisition area in the fourth interface.

S902, at a seventh moment, the terminal equipment receives a first operation in the fourth interface, and responds to the first operation, the terminal equipment displays a fifth interface; the fifth interface comprises a shortcut operation panel and a third button; the third button is used for starting the second application; the seventh moment is later than the sixth moment.

The first operation may correspond to a trigger operation sliding up from the bottom of the screen in the interface shown in a in fig. 5. The fifth interface may be the interface shown in b in fig. 5, and the third button may be the recording application icon 502; the interface shown in b in fig. 5 includes a shortcut operation panel 501 and a recording application icon 502.

S903, at the eighth moment, a second application is run on the foreground of the terminal equipment, and the terminal equipment is in an unlocked state; the fingerprint state is a first fingerprint state; the eighth time is later than the seventh time.

The second application may be a sound recording application. After the terminal equipment starts the recording application, the foreground of the terminal equipment runs the recording application. The terminal device is in an unlocked state, which can be understood as: the terminal equipment is preset with fingerprint unlocking; at the eighth moment, the terminal device does not unlock the screen, and the terminal device only uses part of the functions of the second application.

The fingerprint state is fingerprint_state_stop, and the terminal device is in a state of not monitoring the fingerprint.

S904, at a ninth moment, the second application pulls up the screen locking application, and the terminal equipment displays a sixth interface; the sixth interface comprises a password input interface and a first button, and the flag bit of the first button is a first value; the ninth moment is later than the eighth moment.

The sixth interface may be a password input interface, and the sixth interface may correspond to the interface shown as e in fig. 5; the sixth interface may be bouncer interfaces. The sixth interface includes a first button therein, which may correspond to the first button 508 in the interface shown as e in fig. 5. The flag bit of the first button is False.

The terminal device may pull up the lock screen application using the second application. After the terminal equipment starts the screen locking application, the terminal equipment displays a password input interface, and the flag bit of the first button is a first value.

It can be understood that, at the ninth moment, the terminal device is in an unlocked state and the terminal device does not execute the fingerprint monitoring process, at this moment, the terminal device can input a password unlocking screen in the password input interface, but the terminal device cannot pass through the fingerprint unlocking screen in the password input interface.

S905, at a tenth moment, the terminal equipment receives a triggering operation for a first button, wherein a flag bit of the first button is a second value; the tenth moment is later than the ninth moment.

The trigger operation for the first button may be a trigger operation of clicking the first button 508 in the interface shown as e in fig. 5.

S906, at an eleventh moment, responding to the triggering operation of the first button, displaying a seventh interface by the terminal equipment, wherein the seventh interface comprises a fingerprint acquisition area identifier, and setting the fingerprint state to be a second fingerprint state by the terminal equipment; the eleventh time is later than the tenth time.

The seventh interface may correspond to the interface shown as f in fig. 5. The fingerprint acquisition region identification may correspond to the fingerprint acquisition region identification 509 in the interface shown as f in fig. 5. The terminal device updates the fingerprint state from fingerprint_state_stop to fingerprint_state_running.

According to the fingerprint unlocking method provided by the embodiment of the application, the terminal equipment displays the fourth interface at the sixth moment, and the fingerprint state is the second fingerprint state; at a seventh moment, the terminal equipment receives a first operation in the fourth interface, responds to the first operation, and displays a fifth interface, wherein the fifth interface comprises a shortcut operation panel and a third button; at the eighth moment, the foreground of the terminal equipment runs a second application, and the terminal equipment is in an unlocking state; the fingerprint state is a first fingerprint state; at the ninth moment, the second application pulls up the screen locking application, and the terminal equipment displays a sixth interface; the sixth interface comprises a password input interface and a first button, and the flag bit of the first button is a first value; at a tenth moment, the terminal equipment receives triggering operation aiming at the first button, and the zone bit of the first button is a second value; at an eleventh moment, in response to the triggering operation for the first button, the terminal device displays a seventh interface, wherein the seventh interface comprises a fingerprint acquisition area identifier, and the terminal device sets the fingerprint state to a second fingerprint state. Therefore, a scene of unlocking the screen after the application program is started based on the shortcut operation panel can be provided for the user, and the use experience of the user is improved.

Optionally, steps S901 to S906 are further described below using the second application as an example of the recording application. The fingerprint unlocking method provided by the embodiment of the application further comprises the following steps:

Illustratively, at the eighth moment, the terminal device foreground runs the recording application, and the terminal device displays an eighth interface; the eighth interface includes a fourth button for stopping recording. For example, the eighth interface is an interface shown as d in fig. 5, the fourth button is a stop recording button 507, the stop recording button 507 is included in the interface shown as d in fig. 5, and the fingerprint state is fingerprint_state_stop.

At the ninth moment, the terminal device receives the triggering operation for the fourth button, and the recording application pulls up the screen locking application. For example: the terminal device receives a trigger operation for stopping the recording button 507 in the interface shown in d of fig. 5, and the terminal device starts the screen locking application and enters the interface shown in e of fig. 5. The interface shown as e in fig. 5 includes a first button with a flag bit False.

When the ultrasonic fingerprint unlocking module identifies the fingerprint in the fingerprint acquisition area of the seventh interface and the verification is successful, the terminal equipment displays the stored sound recording file. For example, in the interface shown by f in fig. 5, when the terminal device identifies a fingerprint in the fingerprint acquisition area and the verification is successful, the terminal device enters the interface shown by g in fig. 5, and the interface shown by g in fig. 5 may be an interface on which a sound recording file is displayed.

In order to facilitate understanding of the fingerprint unlocking method provided by the embodiment of the present application, the fingerprint unlocking method in the embodiment of the present application is described in detail below with reference to fig. 10 in a scene shown in fig. 5, and fig. 10 shows a flow chart of the fingerprint unlocking method provided by the embodiment of the present application. As shown in fig. 10:

Exemplary, S1001, the terminal device is on screen.

S1002, the terminal device displays a fourth interface, and the fingerprint state of the terminal device is the second fingerprint state.

The fourth interface may be a lock screen interface, and the fourth interface may correspond to the interface a shown in fig. 5, where the fingerprint state of the terminal device is a second fingerprint state, and may be: FINGERPRINT RUNNING STATE is finger print_state_running.

In one possible implementation, the terminal device may start the second application when the terminal device is in the unlocked state. For example, the terminal device may display an interface b shown in fig. 5, including the shortcut operation panel 501 in the interface b shown in fig. 5, when the terminal device receives an operation of sliding up from the bottom of the screen as shown in the interface a in fig. 5, and the terminal device may start the second application based on the recording application icon 502 in the shortcut operation panel 501.

S1003, when the terminal equipment starts the second application, the terminal equipment updates the fingerprint state into the first fingerprint state.

It can be understood that after the terminal device starts the second application, the terminal device foreground runs the second application, the fingerprint state of the terminal device is the first fingerprint state, and the terminal device can stop monitoring the fingerprint. For example, the terminal device sets FINGERPRINT RUNNING STATE to finger print_state_stop when running the second application. At this time, the terminal equipment can not monitor the fingerprint, also can not use ultrasonic fingerprint unblock module to gather the fingerprint.

S1004, the terminal equipment displays a sixth interface.

The sixth interface may be a password input interface, and the sixth interface may correspond to the interface shown as e in fig. 5, and the sixth interface may include the first button therein. In a possible implementation, when the terminal device foreground runs with the second application, the terminal device may display an interface as shown by c in fig. 5 or an interface as shown by d in fig. 5. When the terminal device receives a trigger operation for stopping the recording button 507 in the interface shown in d of fig. 5, the terminal device may pull up the lock screen application using the second application, and the terminal device displays a sixth interface, with the flag bit of the first button being a first value.

S1005, when the terminal device receives the trigger operation for the first button, the terminal device sets the flag bit of the first button to the second value.

And when the fingerprint unlocking parameters of the terminal equipment meet the preset conditions, the screen locking application sets the fingerprint state to be a second fingerprint state. Specifically, as shown in steps S1006 to S1009:

s1006, the screen locking application judges whether the position of the terminal equipment supporting fingerprint unlocking is in the screen.

When the location where the terminal device supports fingerprint unlocking is in the screen, the terminal device may perform step S1007.

S1007, the screen locking application judges whether the interface displayed by the terminal equipment is a password input interface.

When the interface displayed by the terminal device is a password input interface (for example, mbouncer values of the interface displayed by the terminal device are True), the terminal device may determine whether the position of the first button in the sixth interface is within a range in which the fingerprint can be identified by the ultrasonic fingerprint unlocking module, as shown in step S1008.

S1008, the screen locking application judges whether the distance between the first button and the ultrasonic fingerprint unlocking module is smaller than a first threshold value.

The distance between the first button and the ultrasonic fingerprint unlocking module is greater than or equal to the first threshold, and the terminal device may execute step S1009.

S1009, the lock screen application determines whether the flag bit of the first button is a second value.

In one possible implementation, the flag bit of the first button is a second value, e.g., CLICK SMALL FINGERPRINT is True. The terminal device may set the fingerprint state to a second fingerprint state as shown in step S1010.

S1010, the terminal equipment sets the fingerprint state to be a second fingerprint state.

In step S1005, the terminal device receives a trigger operation for the first button. After the screen locking application performs the determination process of steps S806 to S809, the terminal device may display a seventh interface of the screen locking application in response to the triggering operation for the first button. For example, the terminal device may display the interface shown by f in fig. 5, and the terminal device is in a state of listening to the fingerprint.

Alternatively, in a possible implementation manner, after the terminal device completes step S1009, the terminal device may restore the flag bit of the first button to the first value.

The principles of steps S1001 to S1010 in the embodiment of the present application are similar to those of steps S801 to S810, and the embodiment of the present application will not be described in detail in steps S1001 to S1010.

The above embodiment takes the scenario shown in fig. 5 as an example to explain the fingerprint unlocking method in the embodiment of the present application. The fingerprint unlocking method provided by the embodiment of the application is described below with a scenario shown in fig. 6.

Exemplary, S1101, at the twelfth moment, the terminal device displays a ninth interface, where the ninth interface includes a fingerprint acquisition area identifier; the fingerprint state is a second fingerprint state.

The ninth interface may be a lock screen interface, such as the interface shown as a in fig. 6. The interface shown as a in fig. 6 includes a fingerprint acquisition area identification. The fingerprint state of the terminal device is fingerprint_state_running.

When the terminal equipment displays the lock screen interface, fingerprint monitoring is initiated, and the fingerprint state is updated to be the second fingerprint state. The second fingerprint state may be understood as: the terminal device may identify a user fingerprint of the fingerprint acquisition area in the ninth interface.

S1102, at thirteenth moment, the terminal equipment receives a second operation, and responds to the second operation, and the terminal equipment displays a tenth interface; the tenth interface comprises a password input interface and a first button, and the zone bit of the first button is a first value; the thirteenth moment is later than the twelfth moment.

The second operation may correspond to a slide up operation in the interface shown as a in fig. 6. The tenth interface may be a password input interface, for example, the interface shown in b in fig. 6; the interface shown in b in fig. 6 includes a first button 601 with a flag bit False.

S1103, at a fourteenth moment, the terminal equipment receives trigger operation aiming at a first button in a tenth interface, wherein a flag bit of the first button is a second value; responding to the triggering operation for the first button, and displaying an eleventh interface by the terminal equipment; the eleventh interface comprises a fingerprint acquisition area identifier and a fifth button, and the fifth button is used for canceling fingerprint unlocking; the fourteenth moment is later than the thirteenth moment.

When the terminal equipment receives the triggering operation for the first button, the terminal equipment sets the zone bit of the first button to True. The eleventh interface may be a fingerprint authentication interface, such as the interface shown in c in fig. 6; the fifth button may be a cancel unlock button 603. The interface shown in c in fig. 6 includes a fingerprint acquisition area identification 602 and a cancel unlock button 603.

S1104, at the fifteenth moment, the terminal equipment receives a triggering operation for a fifth button, responds to the triggering operation for the fifth button, and displays a twelfth interface, wherein the fingerprint state is a third fingerprint state; the twelfth interface comprises a password input interface and a first button, and the zone bit of the first button is a first value; the third fingerprint state is used for indicating that the terminal equipment is in a state of not monitoring fingerprints, and the fifteenth moment is later than the fourteenth moment.

The twelfth interface may be a password entry interface, as shown by d in fig. 6. The fingerprint state is fingerprint_state_reporting.

Note that, at the twelfth to fourteenth moments, the fingerprint state of the terminal device is fingerprint_state_running. At the fifteenth timing, when the terminal device receives a trigger operation for canceling the unlock button 603, the terminal device switches the fingerprint state to fingerprint_state_cancel. At this time, the terminal device is in a state of not monitoring the fingerprint.

S1105, at a sixteenth moment, the terminal equipment receives a triggering operation for a first button in a twelfth interface, wherein a flag bit of the first button is a second value; the sixteenth moment is later than the fifteenth moment.

The trigger operation for the first button may correspond to a trigger operation of clicking the first button 508 in the interface shown as d in fig. 6.

S1106, at a seventeenth moment, responding to the triggering operation of the first button, displaying a thirteenth interface by the terminal equipment, wherein the thirteenth interface comprises a fingerprint acquisition area identifier, and setting the fingerprint state to be a second fingerprint state by the terminal equipment; the seventeenth moment is later than the sixteenth moment.

The thirteenth interface may be a fingerprint verification interface, such as the interface shown as e in fig. 6; the thirteenth interface includes a fingerprint acquisition area identifier 605. The terminal device updates the fingerprint state from fingerprint_state_reporting to fingerprint_state_running. At this time, the terminal device is in a state of monitoring the fingerprint, and the terminal device can recognize the user fingerprint of the fingerprint acquisition area, as shown in step S1107.

S1107, when the ultrasonic fingerprint unlocking module identifies the fingerprint in the fingerprint acquisition area of the thirteenth interface and the verification is successful, the terminal equipment displays the fourteenth interface.

In the interface shown in e in fig. 6, when the terminal device identifies a fingerprint in the fingerprint acquisition area and the authentication is successful, the terminal device enters the interface shown in f in fig. 6, and the interface shown in f in fig. 6 may be a desktop.

In order to facilitate understanding of the fingerprint unlocking method provided by the embodiment of the present application, the fingerprint unlocking method in the embodiment of the present application is described in detail below with reference to fig. 12 in a scene shown in fig. 6, and fig. 12 shows a flow chart of the fingerprint unlocking method provided by the embodiment of the present application. As shown in fig. 12:

exemplary, S1201, terminal device bright screen.

S1202, the terminal device displays a ninth interface, and the fingerprint state of the terminal device is a second fingerprint state.

The ninth interface may be a lock screen interface, where the ninth interface may correspond to the interface shown in a in fig. 6, and the fingerprint state of the terminal device is a second fingerprint state and may be: FINGERPRINT RUNNING STATE is finger print_state_running.

In one possible implementation, when the terminal device is in an unlocked state, the terminal device may enter the password input interface. For example, the terminal device may receive a slide-up operation at a ninth interface (an interface shown as a in fig. 6), and the terminal device enters a tenth interface (an interface shown as b in fig. 6). When the terminal device receives a trigger operation for the first button in the tenth interface, the terminal device may display an eleventh interface (interface shown as c in fig. 6). The terminal device may enter the twelfth interface (interface shown as d in fig. 6) based on the cancel unlock button 603 in the eleventh interface.

And S1203, when the terminal device cancels fingerprint unlocking, the terminal device updates the fingerprint state into a third fingerprint state.

It is understood that when the terminal device receives a trigger operation for canceling the unlock button 603, the terminal device cancels the fingerprint unlock. The fingerprint state of the terminal device is a third fingerprint state, and the terminal device cancels the monitoring fingerprint. For example, when the terminal device cancels fingerprint unlocking, the terminal device sets FINGERPRINT RUNNING STATE to fingerprint_state_cancel. At this time, the terminal equipment can not monitor the fingerprint, also can not use ultrasonic fingerprint unblock module to gather the fingerprint.

S1204, the terminal equipment displays a twelfth interface.

The twelfth interface may correspond to the interface shown as d in fig. 6, and a first button may be included in the twelfth interface. In a possible implementation, the terminal device may display an interface as shown in c in fig. 6. When the terminal device receives a trigger operation for canceling the unlock button 603 in the interface shown in c in fig. 6, the terminal device cancels the fingerprint unlock, and the terminal device displays the twelfth interface, with the flag bit of the first button being a first value.

S1205, when the terminal device receives the trigger operation for the first button, the terminal device sets the flag bit of the first button to the second value.

And when the fingerprint unlocking parameters of the terminal equipment meet the preset conditions, the screen locking application sets the fingerprint state to be a second fingerprint state. Specifically, as shown in steps S1206 to S1209:

S1206, the screen locking application judges whether the position of the terminal equipment supporting fingerprint unlocking is in the screen.

When the location where the terminal device supports fingerprint unlocking is in the screen, the terminal device may perform step S1207.

S1207, the screen locking application judges whether the interface displayed by the terminal equipment is a password input interface.

When the interface displayed by the terminal device is a password input interface (for example, mbouncer of the interface displayed by the terminal device is True), the terminal device may determine whether the position of the first button in the twelfth interface is within the range where the fingerprint can be identified by the ultrasonic fingerprint unlocking module, as shown in step S1208.

S1208, the screen locking application judges whether the distance between the first button and the ultrasonic fingerprint unlocking module is smaller than a first threshold value.

The distance between the first button and the ultrasonic fingerprint unlocking module is greater than or equal to the first threshold, and the terminal device may execute step S1209.

S1209, the screen locking application judges whether the flag bit of the first button is a second value.

In one possible implementation, the flag bit of the first button is a second value, e.g., CLICK SMALL FINGERPRINT is True. The terminal device may set the fingerprint state to a second fingerprint state as shown in step S1210.

S1210, the terminal equipment sets the fingerprint state to be a second fingerprint state.

When the Fingerprint unlock parameter of the terminal device satisfies the preset condition, the terminal device may perform a procedure of starting to monitor the Fingerprint (START LISTENING For Fingerprint), and set the Fingerprint state to the second Fingerprint state, for example, the terminal device may set the Fingerprint state to the second Fingerprint state through SET FINGERPRINT running state ().

In step S1205, the terminal device receives a trigger operation for the first button. After the screen locking application performs the determination process of steps S1206 to S1209, the terminal device displays a thirteenth interface in response to the trigger operation for the first button. For example, the terminal device may display the interface shown as e in fig. 6, and the terminal device is in a state of listening to the fingerprint.
