[0005] One aspect of an exemplary embodiment of this disclosure provides a fingerprint unlocking optimization method, the method comprising:

[0006] When a user touches the fingerprint recognition module, the system wake-up process and window drawing process are initiated, and screen brightness blocking is set to prevent the screen backlight from being turned on. During the execution of the system wake-up process and the window drawing process, the fingerprint authentication process is executed in parallel. If fingerprint authentication is successful, the screen light blocking will be lifted and the screen backlight will be turned on; or if fingerprint authentication fails, the wake-up process will be terminated and the system will re-enter sleep mode.

[0007] In another aspect of exemplary embodiments of this disclosure, a fingerprint unlocking optimization device is provided, the device comprising: The fingerprint recognition module is used to initiate the system wake-up process and window drawing process when a user touches the fingerprint recognition module, and at the same time set the screen light blocking, which is used to prevent the screen backlight from being turned on. The data processing module is used to execute the fingerprint authentication process in parallel during the system wake-up process and the window drawing process. The data processing module is also used to unblock the screen and turn on the screen backlight when fingerprint authentication is successful; or to terminate the wake-up process and allow the system to re-enter sleep mode when fingerprint authentication fails.

[0018] The names of messages or information exchanged between multiple devices in the embodiments of this disclosure are for illustrative purposes only and are not intended to limit the scope of such messages or information.

[0019] It is understood that before using the technical solutions disclosed in the various embodiments of this disclosure, users should be informed of the types, scope of use, and usage scenarios of the personal information involved in this disclosure in an appropriate manner in accordance with relevant laws and regulations, and user authorization should be obtained.

[0020] Fingerprint recognition, as an important biometric technology, has been widely used in identity authentication scenarios, such as access control systems, attendance devices, smartphones, tablets, and fingerprint payment. With the increasing prevalence of fingerprint recognition on mobile devices, users are demanding faster unlocking speeds.

[0021] In related technologies, fingerprint unlocking in screen-off state usually adopts a serial processing method. The system only performs operations such as waking up the system, drawing the window and turning on the backlight after successful fingerprint authentication, resulting in a long overall unlocking time and affecting the user experience.

[0022] Therefore, in order to solve the above problems, the exemplary embodiments of this disclosure provide a fingerprint unlocking optimization method. By introducing a phased key value reporting and screen-on blocking mechanism, the time-consuming operations such as system wake-up and interface rendering are brought forward and performed synchronously with the fingerprint authentication process without affecting security authentication. This allows the screen to be lit up quickly at the moment of successful authentication, significantly shortening the overall time from pressing the fingerprint to unlocking the screen and improving the user's operating experience.

[0023] For example, Figure 1 The flowchart of the fingerprint unlocking optimization method provided in the embodiments of this disclosure is as follows: Figure 1 As shown, it can specifically include: Step S110: When a user touches the fingerprint recognition module, the system wake-up process and window drawing process are initiated, and screen-on blocking is set. Screen-on blocking is used to prevent the screen backlight from turning on.

[0024] Step S120: During the system wake-up process and window drawing process, the fingerprint authentication process is executed in parallel.

[0025] Step S130: If fingerprint authentication is successful, unlock the screen and turn on the screen backlight; or if fingerprint authentication fails, terminate the wake-up process and the system re-enters sleep mode.

[0026] In this embodiment, after detecting a user's touch on the fingerprint recognition module, the system initiates the system wake-up process and window rendering process, while simultaneously setting a screen-on blocking control flag. The screen-on blocking control flag temporarily disables the screen backlight, keeping the screen off until unlocking is complete. This allows the time-consuming system preparation and interface rendering to be completed ahead of time without the user's awareness.

[0027] Subsequently, while the system wake-up and window drawing are executed in parallel, the fingerprint authentication process is executed simultaneously.

[0028] Finally, if fingerprint authentication is successful, the screen-on blocking flag is released, the screen backlight is turned on, and the user immediately enters the unlocked interface. If fingerprint authentication fails, the system does not release the screen-on blocking flag and directly triggers the re-sleep process. The power management module will interrupt the current wake-up state and gradually shut down any running modules.

[0029] Based on this, by advancing the wake-up and drawing operations to run in parallel with fingerprint authentication, the overall unlocking time from fingerprint touch to screen illumination is significantly shortened, improving the instantaneous responsiveness of the operation. Furthermore, a screen-on blocking mechanism ensures both security and visual continuity during unlocking by controlling screen illumination.

[0030] Based on the above embodiments, in another embodiment provided in this disclosure, the fingerprint unlocking optimization method may further include: In response to the user touching the fingerprint recognition module, the first key value is reported to the system. The first key value is used to trigger the start of the system wake-up process and the window drawing process. During the continuous pressing of the finger on the fingerprint recognition module, a second key value is reported to the system. The second key value is used to indicate the start of the fingerprint image acquisition process. When the fingerprint image acquisition is completed and the finger leaves the fingerprint recognition module, a third key value is reported to the system. The third key value is used to indicate that the fingerprint acquisition process has ended.

[0031] For example, the fingerprint acquisition process may include three stages, with specific control key values ​​reported at each stage to coordinate system state: When a user's finger touches the fingerprint sensor and generates a valid press event, the system reports the first key value KEY1. The first key value KEY1 indicates the start of the physical interaction for fingerprint recognition.

[0032] During the press-down period, the system initiates the image acquisition process and reports the second key value KEY2. KEY2 indicates that the fingerprint image is being acquired.

[0033] When image acquisition is complete, the system reports the third key value KEY3. KEY3 indicates the end of this fingerprint acquisition cycle.

[0034] Based on this, by dividing the fingerprint acquisition process into three stages with clear status indicators and reporting specific control key values ​​at each stage, the technical problem of inaccurate process triggering timing and poor response coordination caused by the system's inability to accurately perceive the user's operation stage in fingerprint unlocking is solved.

[0035] Based on the above embodiments, in another embodiment provided in this disclosure, the above-mentioned system wake-up process and window drawing process, while simultaneously setting screen-on blocking, may include: In response to the first key value, a wake-up request is sent to the power management module. The wake-up request carries a screen-on blocking flag, which is used to instruct the power management module to disable the screen backlight when executing the wake-up process. The power management module initiates the system wake-up process based on the wake-up request and notifies the window management service to execute the window drawing process.

[0036] For example, the fingerprint unlocking process may include: When the system receives the first key value KEY1, it sends a wake-up request to the power management module, including a screen-on blocking flag. Upon receiving the wake-up request, the power management module gradually restores the functions of each subsystem and simultaneously sends interface drawing instructions to the Window Management Service (WMS). The WMS then begins executing drawing operations such as building the window tree and rendering the interface. At this time, although the system internally marks the screen state as on, the backlight driver module does not receive the lighting instruction due to the screen-on blocking flag, thus the screen remains off.

[0037] Based on this, by sending a wake-up request carrying a screen-on blocking flag to the power management module when the first key value is triggered, the problem of excessive overall unlocking delay caused by the serial execution of wake-up, drawing and authentication operations in the traditional fingerprint unlocking process is solved.

[0038] Based on the above embodiments, in another embodiment provided in this disclosure, the process of unlocking the screen and turning on the screen backlight upon successful fingerprint authentication may include: If fingerprint authentication is successful, the power management module is notified to remove the screen-on blocking flag; After the power management module detects that the screen-on blocking flag has been cleared, it determines whether the window drawing process is complete. Once the window drawing process is complete, perform the operation to turn on the screen backlight; If the window drawing process is not completed, wait for the window to be drawn before performing the screen backlight lighting operation.

[0039] In this embodiment, once the fingerprint authentication process is complete, the system will adopt different control strategies based on the authentication result: If fingerprint authentication is successful, the system first removes the screen-on blocking flag, then checks if the window drawing process is complete and notifies SystemUI of the result. If the window drawing process is complete, SystemUI invokes the power management module to wake up the process. At this point, since the screen-on blocking flag has been removed, the backlight control command can be executed smoothly, the screen immediately lights up, and the user instantly enters the unlocked interface.

[0040] If the window drawing process is not completed, the screen backlight will be turned on while waiting for the window to be drawn.

[0041] Based on this, by establishing a backlight control mechanism based on authentication results and drawing completion status, the problems of inaccurate screen lighting timing, stuttering unlock response, and delayed light effect caused by the uncertain window drawing time in the fingerprint unlock optimization process are solved.

[0042] Based on the above embodiments, in another embodiment provided in this disclosure, the fingerprint unlocking optimization method may further include: If no fingerprint authentication result is received within the preset time, the screen-on blocking flag will be automatically removed, the wake-up process will be terminated, and the system will re-enter sleep mode.

[0043] In this embodiment, the fingerprint unlocking optimization method may further include a state synchronization mechanism: If no authentication result is received within the specified time after the first key value KEY1 is reported, the system will automatically remove the screen-on blocking flag and return to the screen-off state. Simultaneously, modules synchronize in real time via status flags to ensure correct response to abnormal operation scenarios such as interruptions or retries at any execution node.

[0044] Based on this, if no authentication result is received within a preset time, the screen-on blocking is automatically lifted and the system returns to the screen-off sleep state, thereby avoiding the system from continuously maintaining unnecessary wake-up and drawing states due to waiting for timeout response, effectively reducing invalid power consumption and resource occupation.

[0045] Based on the above embodiments, in another embodiment provided in this disclosure, the fingerprint unlocking optimization method may further include: During the parallel execution of the system wake-up process, window drawing process, and fingerprint authentication process, the execution status of each process is synchronized in real time through shared status flags; In the event of an anomaly in the process, the abnormal process is restored based on the shared status flag.

[0046] In this embodiment, a shared status flag can be established to synchronize the execution status in real time among the three parallel processes: system wake-up, window drawing, and fingerprint authentication. Each process updates the flag at key nodes and notifies other processes of their progress, thereby achieving global coordination. The shared status flag may include: in progress, completed, and error.

[0047] When any process encounters an anomaly, the system can accurately pinpoint the source of the problem based on the anomaly information recorded in the shared status flags, and perform process recovery or rollback operations according to preset strategies. Process recovery or rollback operations can include: retaining the completed wake-up and drawing states and waiting for re-authentication, without directly resetting the entire process.

[0048] Based on this, the synchronization and recovery mechanism based on shared status flags ensures that the source of the problem can be quickly located and targeted recovery can be implemented when an anomaly occurs, effectively preventing the spread of single-point failures or the system from falling into an unresponsive state, thereby compressing the anomaly handling time and further shortening the overall unlocking delay.

[0049] For example, Figure 2 This is a schematic diagram of a conventional fingerprint unlocking process provided in the embodiments of this disclosure, such as... Figure 2 As shown, when a user touches the fingerprint sensor, the system reports the key value and then determines whether fingerprint authentication is successful. If fingerprint authentication fails, the process ends directly, and the screen remains off. If fingerprint authentication is successful, the system sequentially performs a wake-up operation, a window drawing operation, and finally illuminates the backlight, turning on the screen and completing the unlocking process. In this process, the wake-up, window drawing, and backlight illumination steps are all executed sequentially after successful fingerprint authentication.

[0050] For example, Figure 3 This is a flowchart illustrating the fingerprint unlocking optimization method provided in the embodiments of this disclosure, as shown below. Figure 3 As shown, when a user touches the fingerprint sensor, the system reports the key value KEY1. After reporting KEY1, the system simultaneously performs wake-up, window drawing, and backlight blocking operations. Although the backlight is blocked at this time, the wake-up and window drawing operations have already started. Then, it determines whether fingerprint authentication is successful. If fingerprint authentication fails, the process ends directly, and the system re-enters sleep mode. If fingerprint authentication is successful, the system further checks whether the backlight is blocked. If so, the system continues to check whether window drawing is complete. If drawing is complete, it performs backlight setting and screen lighting, completing fingerprint unlocking. If drawing is incomplete, it continues to wait until completion before lighting the screen.

[0051] Therefore, in conventional solutions, the system sequentially performs operations such as waking up the system, drawing the window, and turning on the backlight only after successful fingerprint authentication. In contrast, this disclosed solution advances these time-consuming operations to the moment the user presses their fingerprint and receives the fingerprint interrupt signal, meaning that the system initiates the wake-up process and window drawing process in parallel before fingerprint authentication is complete. Only after successful fingerprint authentication does the system execute the backlight-on process, thus significantly shortening the overall time required for fingerprint unlocking in screen-off mode.

[0052] The foregoing primarily describes the solutions provided by exemplary embodiments of this disclosure. It is understood that, in order to achieve the above functions, the electronic device includes corresponding hardware structures and / or software modules for performing each function.

Claims

1. A fingerprint unlocking optimization method, characterized in that, The method includes: When a user touches the fingerprint recognition module, the system wake-up process and window drawing process are initiated, and screen brightness blocking is set to prevent the screen backlight from being turned on. During the execution of the system wake-up process and the window drawing process, the fingerprint authentication process is executed in parallel. If fingerprint authentication is successful, the screen light blocking will be lifted and the screen backlight will be turned on; or if fingerprint authentication fails, the wake-up process will be terminated and the system will re-enter sleep mode.

2. The method according to claim 1, characterized in that, The method further includes: In response to the user touching the fingerprint recognition module, a first key value is reported to the system. The first key value is used to trigger the start of the system wake-up process and the window drawing process. During the continuous pressing of the finger on the fingerprint recognition module, a second key value is reported to the system, which is used to indicate the start of the fingerprint image acquisition process; When the fingerprint image acquisition is completed and the finger leaves the fingerprint recognition module, a third key value is reported to the system. The third key value is used to indicate that the fingerprint acquisition process has ended.

3. The method according to claim 2, characterized in that, The system wake-up process and window drawing process are initiated, and screen-on blocking is set, including: In response to the first key value, a wake-up request is sent to the power management module. The wake-up request carries a screen-on blocking flag, which is used to instruct the power management module to disable the screen backlight when executing the wake-up process. The power management module initiates the system wake-up process based on the wake-up request and notifies the window management service to execute the window drawing process.

4. The method according to claim 3, characterized in that, Upon successful fingerprint authentication, the process of removing the screen light blocking and illuminating the screen backlight includes: If fingerprint authentication is successful, the power management module is notified to remove the screen-on blocking flag; After the power management module detects that the screen-on blocking flag has been cleared, it determines whether the window drawing process is complete. Once the window drawing process is complete, perform the operation to turn on the screen backlight; If the window drawing process is not completed, wait for the window to be drawn before performing the screen backlight lighting operation.

5. The method according to claim 1, characterized in that, The method further includes: If no fingerprint authentication result is received within the preset time, the screen-on blocking flag will be automatically removed, the wake-up process will be terminated, and the system will re-enter sleep mode.

6. The method according to claim 1, characterized in that, The method further includes: During the parallel execution of the system wake-up process, window drawing process, and fingerprint authentication process, the execution status of each process is synchronized in real time through a shared status flag. In the event of an abnormal process, the abnormal process is restored based on the shared status flag.

7. A fingerprint unlocking optimization device, characterized in that, The device includes: The fingerprint recognition module is used to initiate the system wake-up process and window drawing process when a user touches the fingerprint recognition module, and at the same time set the screen light blocking, which is used to prevent the screen backlight from being turned on. The data processing module is used to execute the fingerprint authentication process in parallel during the system wake-up process and the window drawing process. The data processing module is also used to unblock the screen and turn on the screen backlight when fingerprint authentication is successful; or to terminate the wake-up process and allow the system to re-enter sleep mode when fingerprint authentication fails.

8. A computer device, comprising a memory, a processor, and a computer program stored in the memory, characterized in that, The processor executes the computer program to implement the method of claim 1.

9. A computer-readable storage medium having a computer program / instructions stored thereon, characterized in that, When the computer program / instruction is executed by the processor, it implements the method of claim 1.
