Description

Fingerprint identification method and device and computer readable storage medium
Technical Field
The present disclosure relates to the field of terminal technologies, and in particular, to a method and an apparatus for fingerprint identification, and a computer-readable storage medium.
Background
The appearance of the in-plane fingerprint module further increases the screen occupation ratio of the terminal, and the in-plane fingerprint module is a module which is arranged in the terminal and is used for fingerprint identification in a terminal screen for a user. The in-plane fingerprint module in the terminal can acquire the fingerprint information of a user through the fingerprint icon displayed in the screen so as to realize the fingerprint identification function. At present, not only does a screen locking program of a terminal need to call an in-plane fingerprint module for fingerprint identification, but also a third-party application of the terminal needs to call the in-plane fingerprint module for fingerprint identification, so that identity authentication is performed on a user.
Because the in-plane fingerprint module is arranged in the terminal screen, a user cannot visually recognize which area of the terminal screen is the fingerprint identification area of the in-plane fingerprint module. Therefore, when the in-plane fingerprint module is called, a third-party application typically displays a fingerprint icon on the current interface, and prompts the user to press the fingerprint icon. However, since the third-party application is not compatible with the in-plane fingerprint module, the third-party application cannot acquire the fingerprint identification area. Therefore, the third-party application usually displays the fingerprint icon at any position in the current interface, for example, displays a fingerprint icon at an intermediate position of the current interface, and then implements the fingerprint identification function through the fingerprint icon.

Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like 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 invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention.
First, before explaining the embodiments of the present disclosure in detail, an application scenario of the embodiments of the present disclosure is introduced:
the conventional fingerprint module in the terminal is disposed below a screen of the terminal, or at the back of the terminal. However, the fingerprint module arranged below the terminal screen can affect the screen occupation ratio of the terminal, and the fingerprint module arranged on the back of the terminal needs to excavate the terminal, so that the risk of damage to the terminal is increased. Therefore, in order to meet the higher and higher requirements of users on the terminal, an in-plane fingerprint module is currently appeared, namely, the in-plane fingerprint module is arranged in the terminal and provides a module for performing fingerprint identification in a terminal screen for the users. At present, not only does a screen locking program of a terminal need to call an in-plane fingerprint module for fingerprint identification, but also a third-party application of the terminal needs to call the in-plane fingerprint module for fingerprint identification, so that identity authentication is performed on a user.
However, the third-party application is not compatible with the in-plane fingerprint module, that is, the third-party application cannot acquire the fingerprint identification area, so that when the in-plane fingerprint module is called, the third-party application displays a fingerprint icon at any position in the current interface, and further, the fingerprint identification function is realized. However, since the third-party application cannot acquire the fingerprint identification area, the fingerprint icon displayed on the current interface often does not coincide with the real fingerprint identification area, that is, the fingerprint icon cannot accurately reflect the position of the fingerprint identification area, resulting in poor fingerprint identification effect. Therefore, the embodiment of the disclosure provides a fingerprint identification method, by which a third party can accurately reflect the position of a fingerprint identification area in a fingerprint icon displayed on a current interface, thereby improving the accuracy of fingerprint identification.
Next, an implementation environment of the embodiment of the present disclosure is introduced:
referring to fig. 1, a schematic diagram of an implementation environment related to a fingerprint identification method provided in an embodiment of the present disclosure is shown. The implementation environment may include: the terminal 100. The terminal 100 may be a smart phone, a computer, or a multimedia player, and fig. 1 illustrates the terminal 100 as a smart phone.
As shown in fig. 1, an in-plane fingerprint module 1002 may be installed in a screen 1001 of the terminal 100. The functions of unlocking a terminal screen, paying a fingerprint and the like can be completed through the in-plane fingerprint module 1002. The in-plane fingerprint module may be an optical in-plane fingerprint module.
The terminal can be provided with a touch sensing module and a pressure sensor. When the user presses the fingerprint identification area with a finger, the touch sensing module may send position information of the finger to the pressure sensor. The pressure sensor receives the position information, detects the fingerprint identification area and determines whether the finger is positioned in the fingerprint identification area according to the position information of the finger; when the finger is located in the fingerprint identification area, determining that a pressing event that the fingerprint identification area is pressed is detected, determining the event type and the pressure value of the pressing event, and reporting the event type and the pressure value to a screen locking program. And the screen locking program receives the event type and the pressure value reported by the pressure sensor, and determines that the fingerprint identification area is pressed by a finger when the event type is detected to be the designated type and the pressure value exceeds a preset threshold value. The specified type is an event type corresponding to fingerprint identification. And then the screen locking program instructs the display module to set the backlight of the terminal screen to be in a high-brightness mode. In the highlight mode, the screen locking program can control the in-plane fingerprint module through a call-back interface between the screen locking program and the in-plane fingerprint module to acquire the image of the finger, and the image of the finger is used as fingerprint information of the finger. At this time, the in-plane fingerprint module may transmit the fingerprint information to an algorithm program of the terminal. When the algorithm program receives the fingerprint information, the matching degree between the fingerprint information and the fingerprint information in the fingerprint template library can be determined, the matching result is sent to the screen locking program, and the screen locking program forwards the matching result to a third party application, so that the fingerprint identification is completed.
Fig. 2 is a flowchart illustrating a method of fingerprint recognition applied to a screen locking program according to an exemplary embodiment, and includes the following steps, as shown in fig. 2.
In step 201, a call instruction sent by a third-party application of the terminal is received through a callback interface with the third-party application.
In step 202, according to the call instruction, an in-plane fingerprint module integrated on the terminal screen is started.
In step 203, a fingerprint identification area of the in-plane fingerprint module in the terminal screen is acquired, and a fingerprint icon is displayed at the fingerprint identification area of the current interface, wherein the fingerprint icon is used for prompting a user to press a finger in the fingerprint identification area.
In step 204, when it is detected that the fingerprint identification area is pressed by the finger, fingerprint information of the finger in the fingerprint identification area is acquired, and fingerprint identification is performed according to the fingerprint information.
Optionally, before displaying the fingerprint icon at the fingerprint identification area of the current interface, the method further comprises:
and when specific information sent by the in-plane fingerprint module is received, determining that the in-plane fingerprint module is successfully started, and executing the step of displaying the fingerprint icon at the fingerprint identification area of the current interface, wherein the specific information is used for indicating that the in-plane fingerprint module is successfully started.
Optionally, the in-plane fingerprint module is acquired before the fingerprint identification area in the terminal screen, and the method further includes:
determining whether the calling instruction is used for unlocking the terminal screen;
and when the calling instruction is not used for unlocking the terminal screen, executing the step of acquiring the fingerprint identification area of the in-plane fingerprint module in the terminal screen.
Optionally, displaying a fingerprint icon at the fingerprint identification area of the current interface, including:

Optionally, before displaying the fingerprint icon at the fingerprint identification area of the lock screen interface, the method further comprises:
and transparently processing the screen locking interface, wherein the transparently processed screen locking interface is used for displaying prompt information of the third-party application through the screen locking interface.
Optionally, the method further comprises:
detecting the fingerprint identification area;
when a pressing event that the fingerprint identification area is pressed is detected, acquiring an event type and a pressure value of the pressing event;
when the event type is a designated type and the pressure value exceeds a preset threshold value, the fingerprint identification area is determined to be pressed by a finger.
Optionally, acquiring fingerprint information of the finger in the fingerprint identification area includes:
setting the backlight of the terminal screen to be in a high-brightness mode;
and acquiring an image of the finger in the highlight mode, and taking the image of the finger as fingerprint information of the finger.
In the embodiment of the disclosure, a call-back interface between the terminal and a third-party application receives a call instruction sent by the third-party application, and then the in-plane fingerprint module integrated on the terminal screen is started according to the call instruction. The fingerprint identification area of the in-plane fingerprint module in the terminal screen is obtained, and the fingerprint icon is displayed in the fingerprint identification area of the current interface, namely the fingerprint icon can accurately prompt the position of the fingerprint identification area to a user, so that the finger of the user can be pressed in the fingerprint identification area. And then when detecting that this fingerprint identification region is pressed by the finger, acquire the fingerprint information of the finger in this fingerprint identification region to carry out fingerprint identification according to this fingerprint information. That is, the in-plane fingerprint module is started through a callback interface between the in-plane fingerprint module and the third-party application of the terminal, and the fingerprint icon is displayed in the real fingerprint identification area. Therefore, even if the third-party application is not compatible with the in-plane fingerprint module, the user can visually recognize the fingerprint identification area of the in-plane fingerprint module in the terminal screen through the fingerprint icon displayed in the real fingerprint identification area, and then fingerprint identification is realized.
All the above optional technical solutions can be combined arbitrarily to form optional embodiments of the present disclosure, and the embodiments of the present disclosure are not described in detail again.
Fig. 3 is a flowchart illustrating a method for fingerprint identification according to an exemplary embodiment, which is applied to a screen locking program, and as shown in fig. 3, this embodiment will be described with reference to fig. 2. The method comprises the following steps.
In step 301, the third-party application of the terminal sends a call instruction to the screen locking program through a callback interface between the third-party application and the screen locking program.
Due to the characteristics of convenience, rapidness and safety of fingerprint identification, more and more third-party applications integrate the function of fingerprint identification, and then the identity verification of a user is completed through fingerprint identification. When a third-party application performs fingerprint identification, a fingerprint identification area of an in-plane fingerprint module needs to be acquired, and the function of unlocking a terminal screen is often a function of the system, namely the fingerprint identification area can be acquired when the terminal screen is unlocked. Therefore, the callback interface is arranged in the screen locking program, interaction between the third-party application and the screen locking program can be achieved through the callback interface, namely the third-party application can acquire the fingerprint identification area of the in-plane fingerprint module through the screen locking program based on the callback interface, and then fingerprint identification is achieved.
It should be noted that the third-party application may include a plurality of interfaces, for example, a home interface and an interface corresponding to other specified functions, and therefore, the third-party application may detect whether to switch to an interface corresponding to the fingerprint identification function. When the third-party application detects that the interface corresponding to the fingerprint identification function is switched to, it indicates that the third-party application may need to perform fingerprint identification, and at this time, the third-party application may send a call instruction to the screen locking program through a callback interface between the third-party application and the screen locking program. Of course, the user may use the fingerprint identification function in the third-party application more frequently, and therefore, the third-party application may also send a call instruction to the screen locking program through the callback interface between the third-party application and the screen locking program when it is detected that the user opens the third-party application, that is, the third-party application is located on the top page interface. The execution time of the third-party application sending the call instruction to the screen locking program is not limited in the embodiment of the disclosure.
The third party application may be an application that requires authentication of the user using a fingerprint recognition function, for example, a payment application. When the third-party application is the payment application, the third-party application can send a calling instruction to the screen locking program when detecting that the payment is required to be carried out through fingerprint identification, and then the identity of the user is verified. In addition, the callback interface between the third party application and the screen locking program may be a callback interface.
In step 302, when receiving a call instruction sent by a third-party application, the screen locking program starts an in-plane fingerprint module integrated on a terminal screen according to the call instruction.
After receiving a call instruction sent by a third-party application through a callback interface, the screen locking program can determine that the in-plane fingerprint module integrated on the terminal needs to be opened at the moment, and therefore the screen locking program can open the in-plane fingerprint module through interaction between the screen locking program and the in-plane fingerprint module. For convenience and description, the embodiment of the present disclosure refers to an interface between the screen lock program and the third party application as a first callback interface, and refers to an interface between the screen lock program and the in-plane fingerprint module as a second callback interface. Therefore, when the screen locking program receives a calling instruction sent by the third-party application and determines that the in-plane fingerprint module needs to be opened, the in-plane fingerprint module can be controlled to be opened through the second callback interface.
It should be noted that, when the screen locking program controls the in-plane fingerprint module through the second callback interface, the screen locking program may generate an opening instruction according to the received call instruction, where the opening instruction is used to open the in-plane fingerprint module, and then send the opening instruction to the in-plane fingerprint module, and when the in-plane fingerprint module receives the opening instruction, the in-plane fingerprint module may be opened.
Further, after the in-plane fingerprint module is successfully opened, specific information can be sent to the screen locking program through the second callback interface, and the specific information is used for determining that the in-plane fingerprint module is successfully opened. The screen locking program, upon receiving the specific information, may determine that the in-plane fingerprint module has been successfully opened,
the second callback interface and the first callback interface may be the same interface or different interfaces, which is not limited in this disclosure. When the second callback interface and the first callback interface are the same interface, the third-party application and the in-plane fingerprint module interact with the screen locking program through the one interface, so that interface resources are saved, and resources consumed by fingerprint identification are saved. When the second callback interface and the first callback interface are different interfaces, interaction between the third-party application and the screen locking program and interaction between the in-plane fingerprint module and the screen locking program can be carried out simultaneously, interaction efficiency is improved, and fingerprint identification efficiency is improved.
In step 303, the screen locking program determines whether the call instruction is used to unlock the terminal screen, and when the call instruction is not used to unlock the terminal screen, a fingerprint identification area of the in-plane fingerprint module in the terminal screen is obtained.
The in-plane fingerprint module can be called by the screen locking program and the third-party application; therefore, the call instruction may be triggered by the screen locking program itself or by a third-party application. And the calling instruction triggered by the screen locking program is used for unlocking the terminal screen, and the calling instruction triggered by the third-party application is used for verifying the identity of the user. Therefore, the screen locking program has different processing mechanisms according to the call instruction triggered by the screen locking program and the call instruction triggered by the third-party application. Therefore, when receiving the call instruction, the screen locking program can analyze the call instruction and determine whether the call instruction is a call instruction triggered by the screen locking program; when the calling instruction is triggered by the calling instruction, determining that the calling instruction is used for unlocking a terminal screen; and when the calling instruction is not the calling instruction triggered by the calling instruction, namely the calling instruction is the calling instruction triggered by the third-party application, determining that the calling instruction is not used for unlocking the terminal screen.
In a possible embodiment, the calling instruction triggered by the screen locking program carries an identifier of the screen locking program; and the calling instruction triggered by the third-party application carries the identifier of the third-party application. That is, the call instruction may carry an identifier of the screen locking program or an identifier of the third party application. The screen locking program may determine whether the call instruction is a call instruction triggered by itself according to the identifier carried by the call instruction, and the process may be: and the screen locking program analyzes the calling instruction, and then judges whether the calling instruction is a calling instruction triggered by the screen locking program or a calling instruction triggered by a third-party application according to the identifier obtained by analysis. When the analyzed identifier is the identifier of the screen locking program, determining that the calling instruction is the calling instruction triggered by the screen locking program; and when the parsed instruction is the identifier of the third-party application, determining that the calling instruction is a calling instruction triggered by the third-party application. For example, when the third-party application is a payment application, the identifier of the payment may be carried in the call instruction triggered by the third-party application.
It should be noted that, when the screen locking program determines that the call instruction is not a call instruction triggered by itself, that is, when it is determined that the call instruction is not used for unlocking the terminal screen, it may be determined that the call instruction is a call instruction triggered by the third-party application, which indicates that the third-party application needs to acquire the fingerprint identification area by means of the screen locking program at this time, thereby implementing fingerprint identification. Therefore, when the screen locking program determines that the calling instruction is not used for unlocking the terminal screen, the fingerprint identification area of the in-plane fingerprint module in the terminal screen can be acquired.
The screen locking program may determine whether the call instruction is used to unlock the terminal screen when receiving the call instruction, may determine whether the call instruction is used to unlock the terminal screen after receiving the call instruction and opening the in-plane fingerprint module integrated on the terminal screen according to the call instruction, and may also determine whether the call instruction is used to unlock the terminal screen when receiving the call instruction and opening the in-plane fingerprint module integrated on the terminal screen. If the screen locking program receives the call instruction and determines whether the call instruction is used for unlocking the terminal screen while opening the in-plane fingerprint module integrated on the terminal screen, the time spent in the fingerprint identification process can be saved, and the fingerprint identification efficiency is improved.
In addition, after the screen locking program opens the in-plane fingerprint module according to the call instruction, the screen locking program may first receive specific information sent by the in-plane fingerprint module and determine that the in-plane fingerprint module has been successfully opened, and then determine whether the call instruction is used for unlocking the terminal screen, or first determine whether the call instruction is used for unlocking the terminal screen, and then receive specific information sent by the in-plane fingerprint module and determine that the in-plane fingerprint module has been successfully opened, or may also determine whether the call instruction is used for unlocking the terminal screen while receiving specific information sent by the in-plane fingerprint module and determining that the in-plane fingerprint module has been successfully opened, which is not limited in the embodiments of the present disclosure. If the screen locking program receives the specific information sent by the in-plane fingerprint module, determines whether the calling instruction is used for unlocking the terminal screen or not while the in-plane fingerprint module is successfully opened, the time spent in the fingerprint identification process can be saved, and the fingerprint identification efficiency is improved.
In step 304, the screen locking program displays a fingerprint icon at the fingerprint identification area of the current interface, wherein the fingerprint icon is used for prompting the user to press a finger in the fingerprint identification area.
Because the in-plane fingerprint module is arranged in the terminal screen, a user cannot visually identify which area of the terminal screen is the fingerprint identification area of the in-plane fingerprint module, so that the position of the fingerprint identification area can be prompted to the user in a fingerprint icon mode, and fingerprint identification is further completed.
In a possible embodiment, after acquiring the fingerprint identification area of the in-plane fingerprint module in the terminal screen, the screen locking program may superimpose a layer of screen locking interface on the current interface, and display a fingerprint icon at the fingerprint identification area of the screen locking interface. Because the fingerprint icon is displayed in the fingerprint identification area, namely the fingerprint icon can accurately reflect the position of the fingerprint identification area, the fingerprint icon is touched by the finger of the user and is equivalent to the finger of the user pressing in the fingerprint identification area, the fingerprint identification function can be realized at the moment, the misleading of the fingerprint icon to the user is avoided, and the fingerprint identification effect is better.
It should be noted that the screen locking program may also perform transparent processing on the screen locking interface, and the screen locking interface after the transparent processing is used for displaying the prompt information of the third-party application through the screen locking interface. Optionally, after the screen locking program superimposes a layer of screen locking interface on the current interface, the screen locking interface may be transparently processed first, and then a fingerprint icon is displayed in a fingerprint identification area of the screen locking interface after the transparent processing; the fingerprint icon can also be displayed in the fingerprint identification area of the screen locking interface, and then the screen locking interface after the fingerprint icon is displayed is transparently processed, which is not limited by the embodiment of the disclosure. When the screen locking interface after displaying the fingerprint icon is subjected to transparent processing, the areas except the fingerprint icon in the screen locking interface after displaying the fingerprint icon can be subjected to transparent processing.
Since the current interface of the third-party application usually displays some prompt information, for example, when the third-party application is a payment application, a prompt message of "please input a fingerprint and perform authentication by the fingerprint to complete payment" is displayed on the current interface. Therefore, when a layer of lock screen interface containing the fingerprint icon is overlaid on the current interface, in order to prevent the prompt message in the third-party application from being blocked by the overlaid lock screen interface, the lock screen interface is transparently processed by the embodiment of the disclosure. Therefore, the user can not only accurately perform fingerprint identification, but also clearly view all contents displayed in the current interface of the third-party application, wherein the contents include prompt information.
Wherein, in addition to displaying the fingerprint icon at the fingerprint identification area, the fingerprint icon and the fingerprint identification information can be displayed at the fingerprint identification area; the fingerprint identification information is used to prompt the user to press the user's finger at the fingerprint icon. For example, a fingerprint icon and fingerprint identification information of "please press a finger at the fingerprint icon" are displayed at the fingerprint identification area. In this case, the user can view all contents of the third-party application, including the prompt message, through the area of the lock screen interface except for the fingerprint icon and the fingerprint identification information.
In step 305, when the screen locking program detects that the fingerprint identification area is pressed by a finger, fingerprint information of the finger in the fingerprint identification area is acquired, and fingerprint identification is performed according to the fingerprint information.
Because the fingerprint icon is displayed in the fingerprint identification area, and the user can press the finger in the fingerprint identification area according to the prompt of the fingerprint icon, the screen locking program can detect that the fingerprint is pressed by the finger in the area, acquire the fingerprint information of the finger in the fingerprint identification area, and then perform fingerprint identification according to the fingerprint information. Step 305 will be described in detail below by steps (1), (2), and (3):
(1) and the screen locking program detects the fingerprint identification area.
The screen locking program can detect the fingerprint identification area, acquire an event type and a pressure value of a pressing event when the pressing event that the fingerprint identification area is pressed is detected, and determine that the fingerprint identification area is pressed by a finger when the event type is a specified type and the pressure value exceeds a preset threshold value. The specified type is an event type corresponding to fingerprint identification.
In a possible embodiment, the screen locking program can also detect the fingerprint identification area through a pressure sensor. That is, the screen locking program can send an acquisition instruction to the pressure sensor, and the pressure sensor can detect the fingerprint identification area after receiving the acquisition instruction. When the pressure sensor detects a pressing event that the fingerprint identification area is pressed, the event type and the pressure value of the pressing event are determined, and the event type and the pressure value are reported to a screen locking program. And when the event type and the pressure value of the pressing event are received and the event type is a designated type and the pressure value exceeds a preset threshold value, the screen locking program determines that the fingerprint identification area is pressed by the finger.
The pressure sensor can detect whether the position information of the finger sent by the touch sensing module is received or not in the process of detecting the fingerprint identification area after receiving the acquisition instruction, and when the position information of the finger is received, the fingerprint identification area is detected, and whether the finger is located in the fingerprint identification area or not is determined according to the position information of the finger. When the pressure sensor determines that the finger is located in the fingerprint identification area, it is determined that a pressing event in which the fingerprint identification area is pressed is detected.
Because the user may touch the fingerprint identification area by mistake, and the pressure value of touching by mistake is generally smaller, therefore, in order to avoid pressing the event that the user touches the fingerprint identification area by mistake when the user needs fingerprint identification, the embodiment of the disclosure can set a designated type and a preset threshold value, and only when the event type of the pressing event is the designated type and the pressure value exceeds the preset threshold value, the fingerprint identification area is determined to be pressed by the finger, so that the efficiency of fingerprint identification is improved.
(2) And the screen locking program acquires the fingerprint information of the finger in the fingerprint identification area.
When the screen locking program detects the fingerprint identification area and determines that the fingerprint identification area is pressed by a finger, the fingerprint information of the finger in the fingerprint identification area can be acquired. When acquiring the fingerprint information of the finger in the fingerprint identification area, the screen locking program may set the backlight of the terminal screen to a highlight mode, collect an image of the finger in the highlight mode, and use the image of the finger as the fingerprint information of the finger.
It should be noted that, in the process of acquiring the image of the finger by the screen locking program in the highlight mode, the in-plane fingerprint module may be controlled to acquire the image of the finger. That is, the screen locking program can send the information of the adjusted highlight mode to the in-plane fingerprint identification module through the second callback interface between the screen locking program and the in-plane fingerprint module, and the in-plane fingerprint identification module can collect the image of the finger in the highlight mode when receiving the information, and the image of the finger is used as the fingerprint information of the finger.
It should be further noted that, in order to further ensure the security of fingerprint identification, while the screen locking program detects the fingerprint identification area, the in-plane fingerprint module may also detect the fingerprint identification area, and when the in-plane fingerprint module detects a pressing event that the fingerprint identification area is pressed, an event type and a pressure value of the pressing event are obtained, and when the event type is a specific type and the pressure value exceeds a preset threshold value, it is determined that the fingerprint identification area is pressed by a finger. Therefore, the in-plane fingerprint module receives the information of the completion of the adjustment of the highlight mode sent by the screen locking program through the second callback interface, and starts to work when the fingerprint identification area is determined to be pressed by a finger according to the detection of the fingerprint identification area, namely, the image of the finger starts to be collected in the highlight mode, and the image of the finger is used as the fingerprint information of the finger.
Optionally, the screen locking program may further set only the backlight at the fingerprint identification area to be in the highlight mode when acquiring the fingerprint information of the finger in the fingerprint identification area, and acquire the image of the finger, and use the image of the finger as the fingerprint information of the finger.
In order to acquire a clearer finger image, the embodiment of the present disclosure may set a backlight of a terminal screen to a highlight mode when acquiring fingerprint information of a finger, and may also set a backlight at a fingerprint identification area to a highlight mode, and acquire an image of the finger. When the backlight of the terminal screen is set to be in the highlight mode, not only can the images of the fingers be clearly collected, but also the uniformity of the backlight of the terminal screen can bring certain comfort to a user. When the backlight at the fingerprint identification area is set to be in a highlight mode, not only can the image of the finger be clearly collected, but also the electric quantity can be saved, and further the fingerprint identification resources are saved.
(3) And the screen locking program carries out fingerprint identification according to the fingerprint information.
After the screen locking program acquires the fingerprint information of the finger in the fingerprint identification area, fingerprint identification can be performed according to the fingerprint information.
It should be noted that, because the screen locking program can control the image of the finger collected by the in-plane fingerprint module, and use the image of the finger as the fingerprint information of the finger, the in-plane fingerprint module can send the fingerprint information to the algorithm program. When the algorithm program receives the fingerprint information, the matching degree between the fingerprint information and the fingerprint information in the fingerprint template base can be determined, and when the matching degree is greater than the preset matching degree, the matching result is determined to be that the verification is passed; and when the matching degree is not greater than the preset matching degree, determining that the matching result is verification failure. And after the algorithm program determines a matching result, the matching result is sent to the screen locking program, and the screen locking program forwards the matching result to the third-party application.
The fingerprint template library stores at least one piece of fingerprint information of a legal user, the legal user is a user authorized to use the terminal, and the at least one piece of fingerprint information of the legal user is input and stored in the fingerprint template library in the registration stage. In addition, the algorithm program may determine the degree of match between two pieces of fingerprint information through any degree of match algorithm. And the algorithm program can also determine the matching degree between the two fingerprint information according to the characteristic value information of the two fingerprint information. Correspondingly, for each fingerprint information in the fingerprint template library, the step of determining, by the algorithm program, the matching degree between the received fingerprint information and the fingerprint information in the fingerprint template library may be: the algorithm program extracts first characteristic value information of the received fingerprint information, determines second characteristic value information of the fingerprint information in the fingerprint template base, determines the matching degree between the first characteristic value information and the second characteristic value information, and determines the matching degree as the matching degree between the received fingerprint information and the fingerprint information in the fingerprint template base.
When the algorithm program determines the matching degree between the two fingerprint information according to the characteristic value information of the two fingerprint information, the fingerprint template library may store the characteristic value information of at least one fingerprint information, instead of storing at least one fingerprint information of a legitimate user. Of course, the fingerprint template library may also store at least one piece of fingerprint information and at least one piece of feature value information of the fingerprint information. Correspondingly, the step of the algorithm program determining the second feature value information of the fingerprint information in the fingerprint template library may be: and the algorithm program acquires second characteristic value information of the fingerprint information from the fingerprint template library or extracts the second characteristic value information from the fingerprint information of the fingerprint template library.
In the embodiment of the disclosure, a call-back interface between the terminal and a third-party application receives a call instruction sent by the third-party application, and then the in-plane fingerprint module integrated on the terminal screen is started according to the call instruction. The fingerprint identification area of the in-plane fingerprint module in the terminal screen is obtained, and the fingerprint icon is displayed in the fingerprint identification area of the current interface, namely the fingerprint icon can accurately prompt the position of the fingerprint identification area to a user, so that the finger of the user can be pressed in the fingerprint identification area. And then when detecting that this fingerprint identification region is pressed by the finger, acquire the fingerprint information of the finger in this fingerprint identification region to carry out fingerprint identification according to this fingerprint information. That is, the in-plane fingerprint module is started through a callback interface between the in-plane fingerprint module and the third-party application of the terminal, and the fingerprint icon is displayed in the real fingerprint identification area. Therefore, even if the third-party application is not compatible with the in-plane fingerprint module, the user can visually recognize the fingerprint identification area of the in-plane fingerprint module in the terminal screen through the fingerprint icon displayed in the real fingerprint identification area, and then fingerprint identification is realized.
