Description
Technical Field

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terminal equipment related to the embodiment of the invention can be a terminal with a fingerprint identification function, such as a mobile phone, a tablet personal computer and the like, and the terminal equipment comprises equipment for providing voice and/or data service for a user. The positions of the fingerprint acquisition module on the terminal equipment and the power key are overlapped.
Fig. 1 is a schematic diagram illustrating a fingerprint identification process in the related art. Fig. 1 is named by taking a screen locking application module as an example, and the flow of other application modules is the same as that of the screen locking application module, and the reference is only needed.
As shown in fig. 1, keyguard updatemonitor is a lock screen application module, belonging to a user process. Fingerprint Manager, Fingerprint Service and Authentication Client are Fingerprint Android services, and belong to system Service processes. Fingerprintds (fingerprint daemon) are fingerprint native service modules, Hal (Hardware Abstraction Layer) is a fingerprint Hal module, and the fingerprint Hal module and fingerprintds belong to a separate daemon. As can be seen from the above process, the fingerprint identification is accomplished by means of callback.
The screen locking process comprises the following steps: the screen locking application module calls a fingerprint identification interface, a fingerprint Hal module is called by a fingerprint Android service module and a fingerprint native service module, and the fingerprint is in an image scanning mode (waiting for finger release). When the finger is detected, the fingerprint Hal module initiates image acquisition and fingerprint feature matching, and informs a fingerprint native service module of a fingerprint matching result, and then transmits the fingerprint native service to a fingerprint Android service in a callback mode, and finally calls back to the screen locking application module to complete an unlocking function.
However, when the positions of the fingerprint collection module and the power key of the terminal device coincide, as in the fingerprint identification method shown in fig. 1, when the power key is pressed, the fingerprint collection module also responds, and thus the fingerprint operation and the key operation cannot be distinguished.
In order to solve the technical problem, in the fingerprint identification method provided in the embodiment of the present invention, by detecting a key operation of a power key, before the fingerprint Hal module sends a fingerprint matching result to the fingerprint native service module, a notification message is sent to the fingerprint Hal module to indicate whether the fingerprint Hal module sends the fingerprint matching result to the fingerprint native service module. Specifically, when detecting key operation, send first notice message to fingerprint Hal module to instruct fingerprint Hal module to stop sending fingerprint matching result to fingerprint native service module, the power key plays at this moment, and fingerprint operation does not play, and then accurately distinguish fingerprint operation and key operation, improves terminal equipment's user experience.
The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 2 is a flowchart of a fingerprint identification method according to an embodiment of the present invention. The execution subject of this embodiment is a processor in a terminal device, and as shown in fig. 2, the method of this embodiment may include:
s101, judging whether the key pressing operation of the power key is detected.
The power key and the fingerprint acquisition module of this embodiment may be disposed on a side surface of the terminal device, may also be disposed on a front surface of the terminal device, or may be disposed on a back surface of the terminal device, which is not limited in this embodiment.
The fingerprint acquisition module can be a fingerprint sensor and other devices capable of acquiring fingerprint images.
According to the terminal equipment, when a user presses a power key, the time length for the processor in the terminal equipment to detect that the power key is pressed is a first time length, the time length for the fingerprint acquisition module to acquire a fingerprint image and the fingerprint feature matching completion time length of the fingerprint feature module is a second time length, and the first time length is less than the second time length.
Therefore, in order to avoid the interference of the fingerprint operation on the power key processing flow, the processor detects the key operation of the power key, specifically, detects whether the user presses the power key and detects the time for pressing the power key.
Because the processor detects that the key operation is carried out, the fingerprint matching is not completed, so that the processor can send a notification message to the fingerprint Hal module before the fingerprint matching result is generated, namely before the fingerprint Hal module sends the fingerprint matching result to the fingerprint native service module, so as to indicate whether the fingerprint Hal module needs to send the fingerprint matching result to the fingerprint native service module.
S102, when the key operation is detected, sending a first notification message to a fingerprint Hal module, wherein the first notification message is used for indicating the fingerprint Hal module to stop sending a fingerprint matching result to a fingerprint native service module.
The fingerprint matching result is obtained by matching the fingerprint image acquired by the fingerprint acquisition module with a preset fingerprint image.
Specifically, when the processor detects that the user presses the key of the power key, it indicates that the user desires to operate the power key at this time, so as to implement the processing of turning on or off the screen of the terminal device, instead of operating the fingerprint acquisition module. At the moment, the processor sends a first notification message to the fingerprint Hal module, wherein the first notification message is used for indicating the fingerprint Hal module to stop sending the fingerprint matching result to the fingerprint native service module. Therefore, after the fingerprint Hal module receives the first notification message, the generated fingerprint matching result is not sent to the fingerprint native service module, the fingerprint identification result is not called back to the related application module, and the fingerprint operation is stopped. At this time, the power key implements corresponding operations according to key operations, for example, when the terminal device is turned on, the terminal device is turned off after the user presses the power key, or when the terminal device is turned off, the terminal device is turned on after the user presses the power key.
In this embodiment, when the processor does not detect the key operation of the power key, the corresponding situations are many, for example, the user may not perform any operation on the terminal device, or the user touches the fingerprint acquisition module but does not press the power key, or the user does not perform any operation on both the fingerprint acquisition module and the power key.
At this time, the processor needs to analyze and judge whether to send a notification message to the fingerprint Hal module. For example, when the processor judges that the user does not perform any operation on the terminal device or does not perform any operation on the fingerprint acquisition module, the processor does not send a notification message to the fingerprint Hal module.
Optionally, when the processor determines that the user operates the fingerprint acquisition module, the processor may send a notification message to the fingerprint Hal module, and instruct the fingerprint Hal module to call back a fingerprint matching result to the corresponding application module.
Optionally, when the processor determines that the user operates the fingerprint acquisition module, the processor may not send a notification message to the fingerprint Hal module, and at this time, when the fingerprint Hal module does not receive the notification message sent by the processor, the instruction fingerprint Hal module may call back the fingerprint matching result to the corresponding application module.
Based on the above description, in this embodiment, when the processor does not detect the key operation of the power key, the specific processing procedure of the processor is not limited, and is specifically set according to the actual requirement.
According to the fingerprint identification method provided by the embodiment of the invention, whether the key operation of the power key is detected or not is judged, and when the key operation is detected, a first notification message is sent to the fingerprint Hal module so as to instruct the fingerprint Hal module to stop sending the fingerprint matching result to the fingerprint native service module. This embodiment promptly, to the terminal equipment of the coincidence in position of power key and fingerprint collection module, through the key operation who detects the power key, when having solved user operation power key, the problem that the fingerprint operation also responded to accurately distinguish fingerprint operation and key operation, improve terminal equipment's user experience.
Fig. 3 is a flowchart of a fingerprint identification method according to a second embodiment of the present invention. On the basis of the above embodiments, the present embodiment relates to a specific process in which the processor determines whether or not a key operation of the power key is detected. As shown in fig. 3, the S101 may specifically include:
s201, judging whether the application module calls a fingerprint identification interface.
The terminal device of the embodiment may include a plurality of application modules, such as a WeChat module, a Payment treasure module, a power on/off module, and the like.
The Operating system of the terminal device in this embodiment may be an ios (iphone Operating system) mobile Phone Operating system of apple, an Android Operating system of google, a Windows Phone Operating system of microsoft, or an os (Operating system) system of blackberry, and the like, which is not limited in this embodiment.
When the operating system of the terminal device is an Android operating system, then S201 may specifically be: and judging whether an application module in the fingerprint Android service calls the fingerprint identification interface or not.
S202, when the application module is judged to call the fingerprint identification interface, detecting the key pressing operation of the power key.
In this embodiment, in order to accurately detect the key operation of the power key, the processor of this embodiment detects the key operation of the power key when the application module in the terminal device calls the fingerprint identification interface, so as to reduce the detection workload of the processor on the key operation.
In practical use, when an application module in the terminal device starts a fingerprint function, the application module needs to call a fingerprint identification interface of a third party. For example, the user sets the wechat module to realize payment by using a fingerprint, and at this time, the wechat module needs to call a fingerprint identification interface when performing fingerprint payment.
And when no application module calls the instruction identification interface in the terminal equipment, the fingerprint acquisition module in the terminal equipment is in a stop state, and when the fingerprint acquisition module stops working, the fingerprint acquisition module also stops starting, and the fingerprint of the user cannot be sensed. At this moment, when the user pressed the power key, the fingerprint collection module can not cause the interference to the power key.
Therefore, when detecting the key operation of the power key, the processor of this embodiment first determines whether there is an application module in the terminal device to call the fingerprint identification interface. And when the processor judges that an application module in the terminal equipment calls the fingerprint identification interface, the processor detects the key operation of the power key. When the processor judges that no application module calls the fingerprint identification interface in the terminal equipment, the processor does not detect the key operation of the power key, so that the detection workload of the processor on the key operation is reduced, and the detection accuracy of the processor is improved.
On the basis of the above description, when the key operation is detected, the S102 sends the first notification message to the fingerprint Hal module, specifically, when the processor determines that the application module calls the fingerprint identification interface, and detects the key operation of the power key, the processor sends the first notification message to the fingerprint Hal module.
Specifically, the processor judges whether an application module calls the fingerprint identification interface in the terminal device, and when the processor judges that the application module calls the fingerprint identification interface, the processor detects the key operation of the power key. When the processor detects the key operation of the power key, the processor sends a first notification message to the fingerprint Hal module to indicate the fingerprint Hal module to stop sending the fingerprint matching result to the fingerprint native service module. And further, on the basis of realizing accurate difference of key operation and fingerprint operation, the detection workload of the processor is reduced.
According to the fingerprint identification method provided by the embodiment of the invention, the processor firstly judges whether the application module in the terminal equipment calls the fingerprint identification interface, if so, the key operation of the power key is detected, and when the key operation of the power key is detected, the first notification message is sent to the fingerprint Hal module, so that the accurate difference between the key operation and the fingerprint operation is realized, the detection workload of the processor is reduced, and the working reliability of the terminal equipment is improved.
Fig. 4 is a flowchart of a fingerprint identification method according to a third embodiment of the present invention. On the basis of the above embodiments, this embodiment relates to a specific process of detecting the key operation of the power key when the processor determines that the application module calls the fingerprint identification interface. As shown in fig. 4, the step S202 may specifically include:
s301, when the application module calls the fingerprint identification interface, judging whether the fingerprint acquisition module acquires a fingerprint image.
S302, when the fingerprint image is collected by the fingerprint collection module, the key operation of the power key is detected.
During in-service use, there is application module to call the fingerprint identification interface among the terminal equipment, but fingerprint image is not gathered to the fingerprint collection module, for example, when the user does not use the finger to press the power key, fingerprint collection module can't carry out the fingerprint identification operation, can not cause the interference to the power key. At this time, the processor may not detect the key operation of the power key.
In view of the above situation, the processor of this embodiment first determines whether an application module calls the fingerprint identification interface in the terminal device, and determines whether the fingerprint image is acquired by the fingerprint acquisition module after determining that the application module calls the fingerprint identification interface. When the fingerprint image is collected by the fingerprint collection module, the fingerprint collection module is indicated to be touched by a finger of a user, and at the moment, the processor detects the key operation of the power key again to judge whether the power key is pressed by the user.
And when the processor judges that the fingerprint image is not acquired by the fingerprint acquisition module, the processor can not detect the key operation of the power key. Therefore, the detection workload of the processor can be greatly reduced, and the detection accuracy of the processor is improved.
Optionally, in order to further improve the detection accuracy of the processor, when the processor determines that the fingerprint image acquired by the fingerprint acquisition module is valid (the fingerprint image is valid, that is, fingerprint feature information can be clearly extracted from the fingerprint image, and fingerprint feature matching is performed), the processor detects the key operation of the power key. This is because, when the fingerprint image of fingerprint collection module collection was not clear, fingerprint characteristic module can't carry out fingerprint characteristic matching for whole fingerprint operation flow stops, and fingerprint collection module can not disturb the power key. In order to reduce the workload of the processor, the processor may not detect the key operation of the power key at this time.
And S303, when the key operation of the power key is detected, sending a first notification message to the fingerprint Hal module.
On the basis of the above description, when the processor judges that the application module calls the fingerprint acquisition module and judges that the fingerprint acquisition module acquires a fingerprint image (optional, which may be an effective fingerprint image), the processor detects the key operation of the power key. When the processor detects the key operation of the power key, the processor sends a first notification message to the fingerprint Hal module to indicate the fingerprint Hal module to stop sending the fingerprint matching result to the fingerprint native service module, so that the fingerprint operation flow is stopped, and the terminal equipment responds according to the key operation of the power key. And then realize the treater and operate accurate control to the fingerprint, accurately distinguish fingerprint operation and button operation, improve user's experience.
In this embodiment, when the processor determines that the fingerprint image is acquired by the fingerprint acquisition module and determines that the key operation is not detected, it indicates that the user is operating the fingerprint module at this time, and it is expected that fingerprint identification is implemented. At this time, the processor may not send any notification message to the fingerprint Hal module, and before the fingerprint Hal module sends the fingerprint matching result to the fingerprint native service module, when no indication message of the processor is received, the fingerprint Hal module may directly send the fingerprint matching result to the fingerprint native service module, and then call back the fingerprint matching result to the corresponding application module, so that the application module realizes the corresponding operation, for example, completing payment or answering a call.
Optionally, in this embodiment, when it is determined that the fingerprint image is collected by the fingerprint collection module and it is determined that the key operation is not detected, the processor may further execute the following step of S304.
S304, when the fingerprint image is collected by the fingerprint collection module and the key operation is not detected, sending a second notification message to the fingerprint Hal module, wherein the second notification message is used for indicating the fingerprint Hal module to send the fingerprint matching result to the fingerprint native service module.
Specifically, when the processor judges that the fingerprint image is collected by the fingerprint collection module and the key operation is not detected, the processor sends a second notification message to the fingerprint Hal module. As can be seen from the above description, the fingerprint Hal module does not generate the fingerprint identification result when receiving the second notification message. And after receiving the second notification message, the fingerprint Hal module analyzes the second notification message, and when the second notification message is determined to indicate that the second notification message sends a fingerprint matching result, the fingerprint Hal module sends the generated fingerprint identification result to the fingerprint native service module so as to call back the fingerprint identification result to the corresponding application module to complete fingerprint operation.
According to the fingerprint identification method provided by the embodiment of the invention, an application module calls a fingerprint identification interface in terminal equipment, and when a fingerprint image is acquired by a fingerprint acquisition module, a processor detects the key operation of a power key and sends a first notification message to a fingerprint Hal module when the detected key operation is performed so as to instruct the fingerprint Hal module to stop sending a fingerprint matching result to a fingerprint native service module. And when the key operation is not detected, sending a second notification message to the fingerprint Hal module to indicate the fingerprint Hal module to send a fingerprint matching result to the fingerprint native service module. And further, the workload of the processor is reduced on the basis of accurately distinguishing the key operation and the fingerprint operation.
