Technical Field

The present disclosure relates to the field of terminal control technology, and in particular to a method, device and storage medium for controlling a working mode of a fingerprint module.

Background technique

Fingerprint recognition technology has been widely used in terminals. Among them, the fingerprint module in the terminal can use a capacitive fingerprint sensor as the sensor used by the terminal for fingerprint recognition.

Detailed ways

Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

The fingerprint module working mode control method provided by the embodiment of the present disclosure can be applied to a terminal equipped with a fingerprint module and in a scenario where fingerprint authentication and identification is performed based on the fingerprint module, for example, a scenario where the terminal performs fingerprint authentication and identification based on the fingerprint module to realize the terminal unlocking function.

In the related art, the fingerprint module may be a capacitive fingerprint sensor. Its working modes in the working scenario may include: recognition mode and navigation mode. Among them, the recognition mode is a mode for fingerprint monitoring and user identity authentication. Navigation mode is a mode for navigating users to trigger certain events to execute. After unlocking based on fingerprint, the working mode of the fingerprint module will switch from recognition mode to navigation mode, so that the user can trigger navigation events based on the fingerprint recognition function on the terminal to realize the application function. For example, triggering to enter the camera mode in navigation mode, and after entering the camera mode, using fingerprints to control photo shooting, etc. However, after the terminal is unlocked, directly switching the working mode of the fingerprint module from recognition mode to navigation mode can easily trigger navigation events by mistake without the user's knowledge, which in turn causes the fingerprint module to report the mistakenly triggered navigation events to the upper layer of the terminal, resulting in unnecessary power consumption.

In view of this, the present disclosure provides a method for controlling the working mode of a fingerprint module, which can switch the recognition mode of the fingerprint module to the idle (IDLE) mode when the fingerprint authentication is successful. In the idle mode, the fingerprint module is placed in a state of waiting without a task after being unlocked. Since the working mode of the fingerprint module after unlocking is switched from the recognition mode to the idle mode instead of switching to the navigation mode, when the user accidentally touches the fingerprint module without knowing it, the navigation event will not be triggered, thereby helping to avoid useless power consumption of the fingerprint module and reduce the power consumption loss caused by the fingerprint module.

An exemplary embodiment of the present disclosure provides a method for controlling a working mode of a fingerprint module, which is applied to a terminal. The terminal includes a fingerprint module, and can identify fingerprint information.

In one example, the fingerprint module may be a capacitive fingerprint sensor. The working mode of the fingerprint module may include at least a recognition mode and an idle mode. The recognition mode is a working mode for monitoring fingerprints and for user identity authentication. The idle mode is a working mode in which the fingerprint module is in a waiting state without any tasks.

In another example, the type of terminal may include a mobile terminal, such as a mobile phone, a tablet, an iPod, etc. In yet another example, the structure of the terminal may include a double-sided screen terminal, a folding screen terminal, a full-screen terminal, etc.

FIG1 is a flow chart of a method for controlling a working mode of a fingerprint module according to an exemplary embodiment. As shown in FIG1 , the method for controlling a working mode of a fingerprint module is used in a terminal and includes the following steps S11 to S12.

In step S11, the fingerprint authentication result in the recognition mode is determined.

In the disclosed embodiment, the identification mode is a working mode of the fingerprint module for fingerprint monitoring and user identity verification. In the identification mode, fingerprint authentication can be performed on the fingerprint touched on the fingerprint module to determine whether the fingerprint belongs to a valid user's fingerprint, and then obtain a fingerprint authentication result of the fingerprint. Among them, the fingerprint authentication result can represent a successful authentication or a failed authentication. When the fingerprint authentication result is characterized as a successful authentication, it proves that the fingerprint is a legal fingerprint and the terminal can be used. When the fingerprint authentication result is characterized as an unsuccessful authentication, it proves that the fingerprint is an illegal fingerprint and the terminal cannot be used. In one example, the use scenarios for fingerprint authentication may include: terminal unlocking, account authentication or payment and other scenarios.

In step S12, if the fingerprint authentication result indicates that the identity authentication is successful, the working mode of the fingerprint module is switched from the recognition mode to the idle mode.

In the disclosed embodiment, if the fingerprint authentication result indicates that the identity authentication is successful, it indicates that the fingerprint used for fingerprint authentication is a legal fingerprint, and the terminal can be used. In the disclosed embodiment, after determining that the fingerprint authentication is successful, the underlying service of the terminal can switch the working mode of the fingerprint module from the identification mode to the idle mode. In the idle mode, the fingerprint module is in a state of waiting without tasks after being unlocked, so it can save unnecessary power consumption generated by the fingerprint module and reduce power consumption loss.

Through the above-mentioned embodiments, after the fingerprint authentication is successful, the bottom layer service based on the terminal switches the working mode of the fingerprint module from the identification mode to the idle mode without informing the upper layer service. On the other hand, when the working mode of the fingerprint module is switched, the upper layer receives the event after the fingerprint authentication is successful, and there is no need to call and switch the navigation mode, which helps to reduce the power consumption loss caused by the upper layer service calling the navigation mode. In addition, after the working mode is switched to the idle mode, the fingerprint module is in a state of waiting without a task after unlocking, so it can save unnecessary power consumption generated by the fingerprint module, which is beneficial to reduce the overall power consumption waste of the terminal.

In one implementation scenario, when the terminal is in the lock screen state, the fingerprint module works in the identification mode, and at this time, it can monitor whether there is a fingerprint that triggers fingerprint authentication. When a finger press is detected in the identification mode, the fingerprint of the finger is authenticated. If the fingerprint authentication result indicates that the identity authentication is successful, the fingerprint is a legal fingerprint and can pass the unlocking authentication. After the fingerprint authentication is passed, the terminal's underlying service switches the fingerprint module's identification mode to the idle mode, draws the desktop, and completes the unlocking.

In one embodiment, the working mode of the fingerprint module also includes a navigation mode. The navigation mode is a mode for navigating users to trigger certain events, and can trigger and execute corresponding navigation events based on the user's touch. The calling and switching of the navigation mode can be controlled by the upper layer service in the terminal.

FIG2 is a flow chart of another method for controlling the working mode of a fingerprint module according to an exemplary embodiment. As shown in FIG2 , the method for controlling the working mode of a fingerprint module is used in a terminal, and includes the following steps S21 to S23 .

In step S21, the fingerprint authentication result in the recognition mode is determined.

In step S221 , if the fingerprint authentication result indicates that the identity authentication is successful, the working mode of the fingerprint module is switched from the recognition mode to the idle mode.

In step S222, if the fingerprint authentication result continues to indicate that the authentication is unsuccessful within the specified number of times, the working mode of the fingerprint module is switched from the recognition mode to the navigation mode, and non-fingerprint identity authentication is performed in the navigation mode.

In the disclosed embodiment, the threshold of the specified number of times for fingerprint authentication is limited to avoid the deviation of the place where the fingerprint is pressed from the location of the fingerprint module when the user performs fingerprint authentication, resulting in the inability to perform effective authentication in the identification mode when performing fingerprint authentication. If the fingerprint authentication results of the fingerprint are not successfully authenticated within the specified number of times, it is proved that the fingerprint is an illegal fingerprint and cannot access and use the terminal. In order to avoid misidentification of the fingerprint module or to avoid the legal user from being unable to complete the fingerprint authentication normally, the terminal bottom layer will report the unsuccessful authentication event to the upper layer, which calls the navigation mode of the fingerprint module and switches the working mode of the fingerprint module from the identification mode to the navigation mode, so that the legal user can use other identity authentication methods to perform identity authentication. Since the fingerprint module cannot recognize the fingerprint in the navigation mode, a non-fingerprint authentication method is provided in the navigation mode, so that the user corresponding to the current fingerprint can use other touch methods for non-fingerprint identity authentication in the navigation mode. By providing a non-fingerprint identity authentication method, it is possible to avoid the occurrence of an event that the user corresponding to the fingerprint cannot perform identity authentication due to temporary inability to perform fingerprint authentication. In one example, the non-fingerprint identity authentication method may include: password unlocking, pattern unlocking or gesture unlocking.

In step S23, in response to successful identity authentication in the navigation mode, the fingerprint module is switched from the navigation mode to the idle mode.

In the disclosed embodiment, in response to the successful identity authentication of the user corresponding to the fingerprint in the navigation mode, it can be characterized that the user corresponding to the fingerprint is a legitimate user and can use the terminal. After the identity authentication is successful, the upper layer service of the terminal turns off the navigation mode and switches the fingerprint module from the navigation mode to the idle mode to avoid the power consumption caused by the upper layer service sending the navigation event task due to the user accidentally triggering the navigation event without knowing it when the navigation mode is turned on for a long time.

Through the above embodiment, when fingerprint authentication fails, the upper-layer service of the terminal can switch the working mode of the fingerprint module to the navigation mode, so that the user can use other authentication methods for identity authentication based on the navigation mode, thereby helping to avoid the phenomenon of fingerprint misrecognition and allowing the user to use the terminal normally.

In another embodiment, if within the specified number of times, the fingerprint authentication result continues to indicate that the authentication is unsuccessful, and the authentication also fails when the identity authentication is performed in the navigation mode, it indicates that the user currently using the terminal for identity authentication is an illegal user. At this time, the waiting mechanism of the fingerprint module is triggered, and the fingerprint module is canceled from continuing to perform the identity authentication function, so that the fingerprint module cannot perform the identity authentication process within the specified time, thereby protecting the terminal and preventing the user information in the terminal from being leaked. After exceeding the specified time, the fingerprint module is switched from the navigation mode to the identification mode, and the fingerprint and user identity verification are re-monitored to ensure the normal use of the terminal.

In another embodiment, in order to ensure the normal use of the terminal, when the working mode of the fingerprint module is required to be in the navigation mode, the working mode of the fingerprint module can be switched from the idle mode to the navigation mode based on the satisfied trigger conditions and by using the upper layer service. In one example, as shown in FIG3, based on the successful fingerprint authentication, the working mode of the fingerprint module is switched from the identification mode to the idle mode. Among them, FIG3 is a flowchart of another working mode control method of a fingerprint module according to an exemplary embodiment. In another example, as shown in FIG4, the working mode of the fingerprint module is in the idle mode, which can be obtained after switching from the navigation mode after the identity authentication is successful. Among them, FIG4 is a flowchart of another working mode control method of a fingerprint module according to an exemplary embodiment.

Among them, in the embodiment of the present disclosure, the triggering conditions for entering the navigation mode can be pre-set, and then based on the user's operation, the user's triggered event is reported to the upper-layer service, and the upper-layer service monitors it. When the upper-layer service determines that the user's operation meets the triggering conditions for entering the navigation mode, the upper-layer service responds and calls the navigation mode, switching the working mode of the fingerprint module from the idle mode to the navigation mode, so that the fingerprint module can respond to the user's trigger and ensure the normal use of the user.

In one embodiment, determining that the trigger condition for entering the navigation mode is satisfied may be determined based on a first event that the terminal is triggered to execute. The first event in the disclosed embodiment is triggered to execute based on the authentication result of the fingerprint module. That is, the first event is triggered to execute based on successful fingerprint authentication or successful identity authentication. The trigger condition for entering the navigation mode may be a condition that requires calling and using the navigation mode to perform a response function operation. In the disclosed embodiment, in response to the terminal being triggered to execute the first event, it is determined that the trigger condition for entering the navigation mode is satisfied, and the working mode of the fingerprint module is controlled to switch to the navigation mode.

In one example, the first event may be running an application that requires touch operation. When the application is running, the trigger condition for entering the navigation mode is met, and the application processor corresponding to the application notifies the upper-layer service to call and switch the working mode of the fingerprint module to the navigation mode. For example: when the first application is a camera application, running the camera requires fingerprint control of photo shooting. If the camera application is triggered to start, it can be determined that the camera startup event meets the trigger condition for entering the navigation mode. The application processor corresponding to the application notifies the upper-layer service to call and switch the working mode of the fingerprint module to the navigation mode.

In another embodiment, when the first event is executed, it indicates that the user does not need to use fingerprint to trigger related events temporarily, and then the upper layer service turns off the navigation mode and switches the navigation mode to the idle mode to reduce the power consumption of the fingerprint module.

In one implementation scenario, the working mode control flow of the fingerprint module can be shown in Figure 5. When the terminal is in the lock screen state, the working state of the fingerprint module is in the identification mode for fingerprint monitoring. In the identification mode, when the user's finger is detected to press, unlock authentication is performed. If successful, the user's identity authentication is successful, the desktop is drawn, and the working mode of the fingerprint module is switched to the idle mode. If it fails, and the unlocking fails 5 times, the working mode of the fingerprint module is switched to the navigation mode, and the fingerprint unlocking is switched to the password unlocking. If the password unlocking is successful, the working mode of the fingerprint module is switched to the idle mode. If the password unlocking fails, the waiting mechanism is triggered, and after waiting for 30 seconds (s), the working mode of the fingerprint module is switched to the identification mode. Based on the successful identity authentication, in response to the terminal being triggered to execute the first event, it is determined that the triggering condition for entering the navigation mode is met, and the working mode of the fingerprint module is switched from the idle mode to the identification mode. The first event may include taking a photo using a fingerprint. After the first event is executed, the working mode of the fingerprint module is switched from the navigation mode to the idle mode.

Based on the same concept, the embodiment of the present disclosure also provides a device for controlling the working mode of a fingerprint module applied to a terminal, wherein the terminal includes a fingerprint module, and the working mode of the fingerprint module includes at least an identification mode and an idle mode.

It is understandable that the working mode control device of the fingerprint module provided in the embodiment of the present disclosure includes hardware structures and/or software modules corresponding to the execution of each function in order to realize the above functions. In combination with the units and algorithm steps of each example disclosed in the embodiment of the present disclosure, the embodiment of the present disclosure can be implemented in the form of hardware or a combination of hardware and computer software.
