detailed description

The embodiment of the invention provides a method for unlocking the fingerprint of the screen and a terminal for applying the method, so as to shorten the occupation time of the screenless fingerprint unlocking and increase the speed.

Referring to FIG. 1a, the terminal may include a lock screen module 1 and a fingerprint recognition module 2. In addition, the terminal further includes a fingerprint sensor 3.

In one example, the function of the lock screen module 1 described above may be specifically implemented by a lock screen application installed in the terminal.

The function of the fingerprint recognition module 2 can be implemented by a fingerprint recognition service installed in the terminal. In one example, the fingerprint sensor 3, the fingerprint recognition module 2, and the fingerprint service (Fingerprint Service) which will be mentioned later are all part of the fingerprint identification service. When fingerprint recognition is required, the fingerprint recognition function is called through the FingerprintService.

Of course, in another example, the fingerprint recognition service may also not include the fingerprint sensor 3, but includes the fingerprint recognition module 2 and the FingerprintService and the like which will be mentioned later.

Referring to FIG. 1b, from the hardware architecture, the above terminal may include a bus, a processor 101, a memory 102, a communication interface 103, an input device 104, and an output device 105. The processor 101, the memory 102, the communication interface 103, the input device 104, and the output device 105 are connected to each other through a bus. The processor 101 executes the program stored in the memory 102 and invokes other devices, and can be used to implement various steps in the method for unlocking the fingerprint of the screen provided by the foregoing embodiment of the present invention.

Fig. 1c shows an exemplary flow of the method of unlocking the fingerprint from the perspective of the terminal.

FIG. 1d shows an exemplary flow of an off-screen fingerprint unlocking method in which each module (application) of the terminal interacts.

The above method for unlocking the fingerprint of the screen may include the following steps:

Step 100: Detect a touch operation of the terminal fingerprint sensor.

In an implementation, the user touches the fingerprint sensor and the fingerprint sensor detects that it is touched.

Step 101: The lock screen application/module transparently processes the lock screen interface.

As a result of the transparency process, the lock screen interface becomes transparent, so that once the screen is lit, the screen below the lock screen interface is seen by the user.

In one example, the transparency process can be achieved by adjusting the transparency of the lock screen interface. Transparency generally appears as a percentage, completely transparent at 0% and completely opaque at 100%. The transparency can be adjusted to 0% to make the lock screen interface transparent.

In other embodiments of the present invention, the transparent processing of the lock screen interface may also be performed after the fingerprint recognition is successful.

Step 102: The lock screen application/module performs lighting screen processing.

The following will introduce the lighting screen processing.

Step 103: The fingerprint identification service performs fingerprint identification processing.

It should be noted that the fingerprint recognition process and the screen lighting process are performed synchronously by different modules. It saves time compared with the existing ones that start to light the screen after successful fingerprint recognition.

Step 104: If the fingerprint recognition is successful and the screen is successfully illuminated, the unlocking module performs an unlocking operation.

Of course, if the fingerprint recognition fails, failure processing is performed, for example, prompting fingerprint recognition failure.

It can be seen that, in the embodiment of the present invention, the screen lighting process and the fingerprint recognition process are synchronous parallel processing. Compared with the existing ones that start to light the screen after successful fingerprint identification, it can save time and improve processing speed.

At the same time, before the screen lighting process is performed, the lock screen interface is transparent, so that once the screen is lit, the screen under the lock screen interface (the interface before the lock screen) is seen by the user. . Compared with the prior art, from the perspective of the user, after pressing the fingerprint, the interface before the lock screen can be seen more quickly.

It should be noted that when the user sees the interface before the lock screen, the terminal is still unlocked. However, the user will experience a certain time T from seeing the interface before the lock screen, to removing the finger from the fingerprint sensor, and then using the finger to manipulate the interface before the lock screen that he sees. During this time T, the terminal is simultaneously performing an unlocking operation.

Unlocking operations typically take about 100-200ms, while T is generally second-order. Therefore, the user does not feel the pause, which can enhance the user experience.

FIG. 2 illustrates another interactive exemplary process of the above-described screen-off fingerprint unlocking method, which may include at least the following steps:

Step 200: detecting a touch operation of the terminal fingerprint sensor;

When the user touches the fingerprint sensor, the fingerprint sensor detects that it is touched.

Step 200 is similar to step 100 and will not be described here.

Step 201: The terminal raises the operating frequency of the processor to speed up the instruction cycle of the processor, thereby improving the processing speed of the subsequent fingerprint recognition process.

Of course, subsequent transparency processing, unlocking, etc. will also become faster.

In one example, the terminal can include an operating frequency management module that performs an operation of boosting the operating frequency of the processor by the operating frequency management module.

In another example, the functionality of the operating frequency management module can be completed by the underlying layer of the terminal.

In other embodiments, the fingerprint sensor can detect the interruption of the finger press, and the bottom layer detects the interrupt, thereby performing processing for increasing the operating frequency of the processor.

In one example, the underlying layer can call an interface that adjusts the processor frequency for the purpose of increasing the operating frequency.

Taking Qualcomm's chip as an example, the interface that can adjust the processor frequency is specifically a perf_lockr (performance lock) interface, and the bottom layer can call the perf_lockr interface, which corresponds to the perf_lock module. Perf_lock will set the CPU to the node in sysfs (a file system of the Linux kernel), thus changing the maximum/minimum operating frequency of each CPU and turning the CPU on/off.

Alternatively, the operation of raising the operating frequency of the processor may be performed by the fingerprint recognition module.

Step 202: The lock screen application/module transparently processes the lock screen interface.

As a result of the transparency process, the lock screen interface becomes transparent, so that once the screen is lit, the screen below the lock screen interface (ie, the interface before the lock screen) is seen by the user.

Step 202 is similar to the foregoing step 102, and details are not described herein.

Step 203: The lock screen application/module performs screen lighting processing.

The following will introduce the lighting screen processing.

Step 204: The fingerprint identification service performs fingerprint identification processing.

It should be noted that the fingerprint recognition process and the screen lighting process are performed by different modules at the same time. It saves time compared with the existing ones that start to light the screen after successful fingerprint recognition.

Step 205: If the fingerprint recognition is successful and the screen is successfully illuminated, the unlocking module performs an unlocking operation.

Steps 204 and 205 are similar to the foregoing

steps

103 and 104, and are not described herein.

The biggest difference from the foregoing embodiment is that the present embodiment adds an operation of raising the operating frequency of the processor (step 201), so that the processing time can be further shortened.

FIG. 3 illustrates still another interactive exemplary flow of the above-described screen-off fingerprint unlocking method, which may include at least the following steps:

Step 300: detecting a touch operation of the terminal fingerprint sensor;

Step 300 is similar to steps 100 and 200, and is not described herein.

Step 301: The terminal increases the operating frequency of the processor to speed up the instruction cycle of the processor, thereby improving the processing speed of the subsequent fingerprint recognition process.

Step 301 is similar to step 201 and will not be described here.

Step 302: The lock screen application/module receives the touch event notification, and transparently processes the lock screen interface.

In other embodiments, the fingerprint sensor sends a touch event notification to the lock screen application when a finger touch is detected. After receiving the notification, the lock screen application is transparent.

In one example, the touch event notification can be carried in a callback message. The callback message delivery path is: after the fingerprint sensor is touched, the callback is sent to the fingerprint server framework through the FingerprintDaemon of the Hardware Abstract Layer, the framework FingerprintService forwards the callback to the FingerprintManager, and the FingerprintManager forwards the callback to Lock screen application.

Of course, from the perspective of the lock screen application, the fingerprint recognition module sends a touch event notification to it.

For the related content of the transparent processing, refer to the foregoing step 102, which is not described herein.

Step 303: The fingerprint identification module (fingerprint identification service) captures an image;

Step 304: The fingerprint identification module (fingerprint identification service) matches the captured image with the preset fingerprint image to obtain a matching result, and the matching result is used to indicate whether the fingerprint identification is successful.

In other embodiments, the capture and matching can be initiated by the hal layer, particularly FingerprintHal.

The real capture and matching are in the TEE layer (Trust Execution Environment) Finish and get the matching result. Because the code running environment is trusted, the matching result is also trusted. Then the matching result is returned to FingerprintHal, and then forwarded to the FingerprintManager step by step, so that the called lock screen application gets the matching result.

In one example, the number 0 can be used to characterize the success of the fingerprint recognition, the digit 1 is used to characterize the fingerprint recognition failure, or vice versa; in another example, the flag can be used to characterize whether the fingerprint recognition is successful, the flag has two values, and one representation is successful. A representation failure.

There are other types of signals in actual conditions, so more than two flags are used to indicate different states. For example, the status of fingerprint recognition may include three states of finger contact sensor, image capture, and recognition success/failure, and three flags may be used to indicate these three states.

Step 303 and step 304 are refinements of the fingerprint recognition process of all the aforementioned embodiments.

Step 305: The lock screen application/module performs screen lighting processing.

Step 306: If the fingerprint recognition is successful and the screen is successfully illuminated, the unlocking module performs an unlocking operation.

FIG. 4a illustrates still another interactive exemplary flow of the above-described screen-off fingerprint unlocking method, which may include at least the following steps:

Step 400: The user touches the fingerprint sensor, and the fingerprint sensor detects that it is touched.

Step 400 is similar to steps 100, 200, and 300, and is not described herein.

Step 401: The terminal increases the operating frequency of the processor.

Step 401 is similar to steps 201 and 301, and is not described herein.

Step 402: The lock screen application/module transparently processes the lock screen interface.

Step 402 is similar to the foregoing steps 101, 202, and 302, and is not described herein.

Step 403: The fingerprint identification module captures an image.

Step 404: The fingerprint identification module matches the captured image with the preset fingerprint image to obtain a matching result, where the matching result is used to indicate whether the fingerprint identification is successful.

Steps 403 and 404 are similar to steps 303 and 304, respectively, and are not described herein.

Step 405: The lock screen application/module notifies the bottom layer to perform window drawing.

In other embodiments, the underlying drawing window is notified by the lock screen application via a window manager (Windowmanager). For details on how to draw a window, please refer to the existing drawing window mode, which will not be described here.

Step 406: If the window drawing is completed and the fingerprint recognition is successful, the window manager performs a lighting operation of the screen illumination source.

In one example, the program that illuminates the screen is turned on by the lock screen application/module, and the program determines whether to illuminate the backlight according to whether the window drawing and fingerprint recognition are completed, and the final judgment point is in the window manager.

In other embodiments, in the process of unlocking the screen, the command to be lit is issued by the lock screen application to the wakeup interface of the power manager (PowerManager), and the window manager checks the window drawing result/status during the lighting process. And the fingerprint identification result/state. If the window drawing is completed and the fingerprint recognition is successful, the power manager is finally notified to illuminate the illumination source.

In one example, the window manager will get the status of the fingerprint recognition. The status of fingerprint recognition may include three states of finger contact sensor, image capture, and success/failure recognition. When the success status is recognized and the window drawing is completed, the power manager is notified to illuminate the screen illumination source.

In one example, the screen illumination source can be a Light Emitting Diode (LED) backlight. Of course, the screen illumination source can also be an organic light emitting diode (OLED) light source or other light source.

Step 407: If the fingerprint recognition is successful and the screen illumination source is successfully illuminated, the unlocking module performs an unlocking operation.

It should be noted that after the fingerprint recognition fails, the lighting source of the screen illumination will not be lit. The lighting process will be interrupted.

Figure 4b shows the modules in the terminal after the user puts a finger on the fingerprint sensor. Piece) The process of lighting up in two branches (paths).

To distinguish them, two branches (paths) are represented by numbers and English respectively.

Path 1:

S1-S3: After the fingerprint sensor is touched, the callback is forwarded to the lock screen application through FingerprintHal, FingerprintService, and the like.

S4: the lock screen application sends a lighting command to the power manager;

See step 406 for details.

S5: the power manager sends a lighting command to the window manager;

S6: The window manager notifies the SurfaceFinger to draw the window;

S7: The window manager gets the drawing result/status from SurfaceFinger.

The window manager can actively obtain the drawing result/status from the SurfaceFinger, and the SurfaceFinger can also send the drawing result/status to the window manager.

S8: The window manager notifies the power manager to illuminate the illumination source when the window drawing is completed and the fingerprint recognition is successful.

Path 2:

a: The fingerprint sensor detects the interruption of the finger press;

b: FingerprintHal initiates execution of the capture and match.

The actual capture and matching are done in the TEE layer and the results are matched. Because the code running environment is credible, the resulting matching result is also trusted, and the matching result is returned to FingerprintHal.

C-e: The matching result (fingerprint result/status) is forwarded to the window manager via FingerprintHal, FingerprintService, lock screen application, and so on.

After the window manager obtains the drawing result/status (characterization completion) and the matching result (the characterization is successful), the above step S8 is performed.

Surfaceflinger is a class, and at the same time it is a thread. The thread is continuously calculated through loops. And refresh the display content required by the current screen. The Surfaceflinger thread belongs to the SystemServer process, that is, the Surfaceflinger thread is started in the SystemServer process. Surfaceflinger holds various layers, and its main job is to be responsible for the fusion of various layers, so it can be seen as a thread for maintaining various layers. To start the Android thread, you need to provide two interfaces. One is readyToRun(), which defines the content that needs to be initialized before the thread loops. The second is threadLoop(), which must be implemented by each thread. This function defines the thread execution content. The function returns true (true), the thread will continue to call threadLoop(), and if false (false) is returned, the thread will exit.

In one example, the value in the rendering result/state can be 0 or 1, with the number 0 indicating that the window plot is incomplete, the digit 1 is used to characterize the window plot not complete, or vice versa; in another example, the flag can be used to characterize the window plot Whether it is completed, the flag has two values, one is completed, and one is not completed.

Similarly, in one example, the value in the fingerprint identification result/state can be 0 or 1, the digit 0 can be used to characterize the fingerprint recognition success, the digit 1 is used to characterize the fingerprint recognition failure, or vice versa; in another example, the flag can be used to characterize Whether fingerprint identification is successful, flag has two values, one is successful, and one is failed. There are other types of signals in actual conditions, so more than two flags are used to indicate different states. For example, the status of fingerprint recognition may include three states of finger contact sensor, image capture, and recognition success/failure, and three flags may be used to indicate these three states.
