Detailed Description
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, 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 fingerprint acquisition method provided by the embodiment of the invention is applied to a terminal, and the terminal can be a smart phone, a computer, a multimedia player, an electronic reader, a wearable device and the like.
The fingerprint acquisition method and the terminal provided by the invention are described in detail by listing a plurality of specific embodiments.
Example one
Referring to fig. 1, a flowchart illustrating steps of a fingerprint acquisition method according to an embodiment of the present invention is shown, which may specifically include the following steps:
At present, because the pursuit of terminal pair ultra-narrow frame and high-screen proportion at present, the cell-phone manufacturer is keen on reducing the terminal machine and on one's body unnecessary subassembly, and along with full-screen fingerprint unblock technique has gradually developed maturity, apple, samsung etc. cell-phone manufacturers' next generation smart machine or all will cancel fingerprint unblock button, adopt full-screen fingerprint unblock technique, in concrete realization, full-screen fingerprint unblock technique has two kinds of implementation:
first, can be provided with fingerprint sensor in the regional below of presetting of touch-sensitive screen, when the user is touching the preset region of screen with the finger, can accomplish fingerprint collection and discernment operation through fingerprint sensor.
Second, a fingerprint sensor is disposed under the entire touch screen, and when a user touches any area of the screen with a finger, fingerprint collection and recognition operations can be completed through the fingerprint sensor.
Compared with the first implementation mode, the second implementation mode has a larger area for fingerprint unlocking and is more free to operate, so that the second implementation mode is widely applied at present, and the terminal based on the full-screen fingerprint identification provided by the invention does not limit the fingerprint detection mode, such as: the fingerprint detection method may be capacitive detection, optical detection, ultrasonic detection, or the like.
Further, in the embodiment of the present invention, after the terminal starts the application and enters the application interface, when the triggerable control of the application is triggered, a functional area corresponding to the triggerable control appears in the touch screen, for example: the user clicks the functional areas to trigger and execute the triggerable controls corresponding to the functional areas.
Therefore, when a triggerable control corresponding to the application and related to fingerprint identification is triggered in the terminal to enter a corresponding fingerprint identification scene, because a functional area (such as a 'return' button, a 'cancel' button, a menu, a submenu and the like) corresponding to the triggerable control occupies a partial area of a terminal screen, in order to avoid the situation that a user clicks the functional area of other functional controls and triggers fingerprint identification to cause functional confusion, a first fingerprint identification area can be determined in other areas except the functional area in the touch screen, and fingerprint data are collected through the first fingerprint identification area
In summary, according to the fingerprint acquisition method provided in the embodiment of the present invention, when a triggerable control corresponding to an application and related to fingerprint identification is triggered in a terminal and enters a corresponding fingerprint identification scenario, a function area corresponding to the triggerable control is displayed on a current application interface, the function area of the triggerable control in the current display interface is determined, a first fingerprint identification area is determined from other areas except the function area in a touch screen, and fingerprint data is acquired through the first fingerprint identification area. The purpose of dynamically adjusting the fingerprint identification area to the position where the touch function is not responded is achieved, the problem that the touch function is disordered due to an existing fingerprint identification method is solved when the touch operation area and the fingerprint identification operation area are overlapped, and the user experience is improved.
Example two
Referring to fig. 2, a flowchart illustrating specific steps of a fingerprint acquisition method according to an embodiment of the present invention is shown, which may specifically include the following steps:
In the embodiment of the present invention, after the terminal opens the application and enters the application interface, when the triggerable control of the application is triggered, a functional area corresponding to the triggerable control appears in the touch screen, for example: the user clicks the functional areas to trigger and execute the triggerable controls corresponding to the functional areas.
This step can refer to step 102, which is not described herein again.
Optionally, step 202 may further include sub-step 2021, sub-step 2022, and sub-step 2023.
In the substep 2021, coordinates of the functional area and a position where a second fingerprint identification area in the touch screen is located are obtained, where the second fingerprint identification area is a default fingerprint identification area of the terminal.
It should be noted that, referring to fig. 2A, a schematic diagram of a terminal fingerprint identification interface is shown, in the process of performing fingerprint identification based on a full screen of a terminal 10, fingerprint identification may be performed in a second fingerprint identification area 11 preset in a touch screen, where the second fingerprint identification area 11 may be an area that is best in ergonomics by default in the touch screen, or may be an area that is set by a user by himself or herself as a preferred area.
Further, after the terminal starts the application and enters the application interface, when the triggerable control corresponding to the application and related to fingerprint identification is triggered, the fingerprint identification control is called, and a corresponding fingerprint identification scene is entered, for example: fingerprint collection, fingerprint unlocking, fingerprint payment, fingerprint encryption and decryption, fingerprint login and other scenes. At this time, the fingerprint recognition function of the second fingerprint recognition area 11 is turned on, and the user touches the second fingerprint recognition area 11 with a finger to perform fingerprint recognition.
For example: referring to fig. 2B, when the user uses the WeChat payment to settle accounts after shopping in the store, the user opens the WeChat application of the mobile phone, clicks the first payment submenu in the wallet menu to generate a payment two-dimensional code, and after the clerk scans the two-dimensional code, a fingerprint payment verification interface 12 is generated to prompt the user to verify a fingerprint to confirm payment, the user performs fingerprint verification by touching the second fingerprint identification area 11 with a finger, and if verification is successful, payment is successful, and the transaction is completed.
In the embodiment of the invention, the terminal can acquire the coordinate information of a certain screen area of the terminal through a third-party coordinate acquisition software development kit, and can also display the coordinate information of each area in the terminal screen through the privacy-developer tool-display pointer application of the terminal system.
In the sub-step 2022, if the functional area coincides with the second fingerprint identification area, an area that does not coincide with each functional area is selected as the first fingerprint identification area, and fingerprint data is collected through the first fingerprint identification area.
According to the coordinates of the positions of the functional area and the second fingerprint identification area obtained in the sub-step 2021, it is determined whether the coordinates of the positions of the functional area and the second fingerprint identification area are overlapped, if so, a first fingerprint identification area different from the second fingerprint identification area may be selected and the fingerprint identification function of the first fingerprint identification area is turned on for fingerprint identification, where the first fingerprint identification area is a "blank" area in the current interface, that is, an area that does not interfere with the second fingerprint identification area nor with the functional area.
In the specific implementation of the embodiment of the present invention, referring to fig. 2C, when a triggerable control corresponding to an application and related to fingerprint identification is triggered in a terminal 10 and enters a corresponding fingerprint identification scenario, since a functional area (such as a "return" button, a "cancel" button, a menu, a sub-menu, etc.) corresponding to the triggerable control and a second fingerprint identification area 11 for performing fingerprint identification are both located in a current application interface, the second fingerprint identification area 11 in which fingerprint identification operation is easily performed and a certain touch-enabled functional area 13 overlap, and both are touch screens for users. When fingerprint identification is started, the touch fingerprint triggers the functional areas of other functional controls at the same time, or the functional areas of other functional controls are clicked to trigger the fingerprint identification, so that functional confusion is generated, such as: in a terminal fingerprint payment verification scene, a display position of a 'cancel verification' menu is overlapped with a second fingerprint identification area 11 for fingerprint identification, at this time, when a user clicks the second fingerprint identification area 11, the 'cancel verification' menu is easily touched by mistake, so that trigger confusion of a 'cancel verification' function and a 'fingerprint verification' function is caused.
Therefore, in the embodiment of the present invention, referring to fig. 2C, when a certain functional area of the terminal overlaps with the second fingerprint identification area, a first fingerprint identification area 14 different from the second fingerprint identification area 11 may be replaced and the fingerprint identification function of the first fingerprint identification area 14 is turned on for fingerprint identification, where the first fingerprint identification area 14 is a "blank" area in the current interface, that is, an area that neither overlaps with the second fingerprint identification area 11 nor overlaps with the functional area. It should be noted that, based on the full-screen fingerprint identification technology, the terminal may precisely control, through the processor, the on or off of the fingerprint identification function in a certain area of the touch screen, and when the functional area overlapped with the second fingerprint identification area is a dynamic area whose position is constantly changed, the terminal may correspondingly dynamically adjust the first fingerprint identification area through the processor.
After a first fingerprint identification area different from the second fingerprint identification area is replaced and the fingerprint identification function of the first fingerprint identification area is started, the fingerprint identification function of the second fingerprint identification area is closed through a processor of the terminal, so that the second fingerprint identification area can not identify fingerprints any more, and only responds to the touch function of the function area.
It should be noted that a plurality of preset fingerprints, which can be added or deleted by a user, of a trusted user are stored in a memory of the terminal in advance, when the terminal is on the screen, after the fingerprint input by the user in a preset area is collected by a fingerprint sensor, the fingerprint is matched with all the fingerprints stored in the memory, if the matching is successful, an access right is given, the user is allowed to unlock and awaken the touch screen of the terminal, and if the matching is successful, the access is denied.
The fingerprint matching is based on a fingerprint comparison technology, the clearest fingerprint image is selected through an image processing technology, the image of the human fingerprint is read through a fingerprint sensor, and after the fingerprint image is obtained, the original image of the fingerprint image is subjected to primary processing to be clearer. Next, a digital identification template (feature data) of the fingerprint image is established by the fingerprint identification software, and two different fingerprints will not generate the same feature data. And finally, comparing the templates of the two fingerprints by a computer fuzzy comparison method, calculating the similarity of the templates, and finally obtaining a matching result of the two fingerprints.
And a substep 2023 of displaying a fingerprint identification prompt interface in the first fingerprint identification area, wherein the fingerprint identification prompt interface comprises at least one of a text prompt interface, a pop-up frame display interface and a pattern display interface.
In the embodiment of the invention, in order to clearly prompt a user to perform fingerprint identification and enable the changed fingerprint identification area to have a visual effect, a fingerprint identification prompt interface can be displayed in the first fingerprint identification area, wherein the fingerprint identification prompt interface is one of a character prompt interface, a pop-up frame display interface and a pattern display interface.
Therefore, the pattern display interface displayed in the first fingerprint identification area may refer to the display interface of the second fingerprint identification area 11 in fig. 2A, that is, a fingerprint pattern, which may have flickers of brightness and color to increase visual effects. When the display in the first fingerprint identification area is the display interface of the pop-up box, a message pop-up box can be popped up in the first fingerprint identification area, and the content of the message pop-up box is a text prompt.
Before the step of replacing a first fingerprint identification area different from the second fingerprint identification area and starting the fingerprint identification function of the first fingerprint identification area, a fingerprint identification prompt interface can be displayed in the second fingerprint identification area, the fingerprint identification prompt interface can refer to the fingerprint identification prompt interface in the first fingerprint identification area, and after the step of replacing a first fingerprint identification area different from the second fingerprint identification area and starting the fingerprint identification function of the first fingerprint identification area, the fingerprint identification prompt interface in the second fingerprint identification area is closed.
In the embodiment of the invention, the system event can be monitored through a monitor of the Activity control (suitable for an android system), and the monitor can monitor the interface information in the current interface of the terminal.
Therefore, the corresponding relation between the functional area corresponding to each triggerable control in the current application interface of the terminal and the first fingerprint identification area can be monitored and recorded through the monitor.
And 204, when the application interface is entered again, selecting the first fingerprint identification area to acquire fingerprint data according to the corresponding relation between each functional area in the application interface and the first fingerprint identification area.
Based on step 204, when the functional area overlaps with the second fingerprint identification area, a first fingerprint identification area different from the second fingerprint identification area is selected, the fingerprint identification function of the first fingerprint identification area is started, after the fingerprint identification is completed, the corresponding relation between each functional area and the first fingerprint identification area in the application interface at this time is recorded through the monitor of the Activity control, and when the same application interface is entered again and the same triggerable control is triggered to display the functional area, the first fingerprint identification area is directly used as the fingerprint identification area. The method has the advantage of simplifying the adjustment process of the fingerprint identification area when the same application interface is triggered.
For example, when the user uses the payment device to perform payment verification, the fingerprint verification area is not in conflict with the functional area of the triggerable control, and the fingerprint identification is directly performed in the default fingerprint identification area;
when the user uses the WeChat to carry out payment verification, because the fingerprint verification area conflicts with the functional area of the triggerable control, the dynamically adjusted second fingerprint identification area which does not interfere with the functional area of the triggerable control is used for carrying out fingerprint identification, meanwhile, the mobile phone records the corresponding relation between the second fingerprint identification area and the functional area of the triggerable control, and when the WeChat is opened again to carry out payment verification, the second fingerprint identification area is directly used for carrying out fingerprint identification.
In summary, in the fingerprint acquisition method provided in the embodiments of the present invention, when the corresponding triggerable control related to fingerprint identification is triggered in the terminal and enters the corresponding fingerprint identification scenario, displaying a functional area corresponding to the triggerable control on the current application interface, and when the functional area is overlapped with the second fingerprint identification area, a first fingerprint identification area different from the second fingerprint identification area is replaced and the fingerprint identification function of the first fingerprint identification area is started, and the fingerprint identification function of the second fingerprint identification area is closed, and the terminal can record the corresponding relation between each functional area in the current application interface and the first fingerprint identification area, and when the terminal enters the application interface again, and selecting the first fingerprint identification and starting the fingerprint identification function of the first fingerprint identification according to the corresponding relation between each functional area in the application interface and the first fingerprint identification. The purposes of dynamically adjusting the position of the fingerprint identification area to the position of the touch function and simplifying the adjustment process of the fingerprint identification area are achieved, the problem that other touch functions are triggered by mistake when the fingerprint is identified is avoided, when the touch operation area and the fingerprint identification operation area are overlapped, the problem that the touch function is disordered due to the existing fingerprint identification method is solved, and the user experience is improved.
EXAMPLE III
Referring to fig. 3, a flowchart illustrating specific steps of another fingerprint acquisition method according to an embodiment of the present invention is shown, which specifically includes the following steps:
This step may refer to step 201, which is not described herein again.
This step can refer to step 202, which is not described herein again.
Optionally, step 302 may further include sub-step 3021, sub-step 3022, and sub-step 3023.
And a substep 3021, obtaining coordinates of the functional area and a position of a second fingerprint identification area in the touch screen, where the second fingerprint identification area is a default fingerprint identification area of the terminal.
This step can refer to the above substep 2021, which is not described herein.
And a substep 3022, selecting, if the functional regions coincide with the second fingerprint identification region, a region that does not coincide with each functional region as the first fingerprint identification region, and collecting fingerprint data through the first fingerprint identification region.
This step can refer to the sub-step 2022, which is not described herein.
And a substep 3023, displaying a fingerprint identification prompt interface in the first fingerprint identification area, where the fingerprint identification prompt interface includes at least one of a text prompt interface, a pop-up frame display interface, and a pattern display interface.
This step can refer to the above substep 2023, which is not described herein.
In a specific implementation of the embodiment of the present invention, if a first fingerprint identification area that is different from the second fingerprint identification area and is not overlapped with each function area is not selected from the current application interface, that is, the utilization rate of the current interface reaches a peak value, an area that can support the size of the fingerprint identification requirement and is not overlapped with each function area that can trigger a control in the current application interface cannot be selected. At this time, the database can be called through the Activity control, and historical data of the user use frequency of each functional area in the current application interface is obtained. For example, referring to fig. 3A, in the fingerprint payment verification interface, the functional area 12 is a prompt information interface, cannot be used as a fingerprint identification area, the historical user usage frequencies of calling the functional area 13, the functional area 15, the functional area 16, the functional area 17, and the functional area 18 in the database through the Activity control are A, B, C, D, E respectively, and a > B > C > D > E.
In a particular implementation, for example, referring to FIG. 3A, in the fingerprint payment verification interface, the historical user usage frequencies of functional area 13, functional area 15, functional area 16, functional area 17, and functional area 18 are A, B, C, D, E, respectively, and A > B > C > D > E. At this time, the third fingerprint identification area 19 is selected to cover the functional area 18 with relatively low user frequency, and the fingerprint identification function of the third fingerprint identification area is started to perform fingerprint identification, so that the purpose of dynamically adjusting the fingerprint identification area is achieved under the condition that the current interface utilization rate of the touch screen reaches the peak value, and the applicability of the fingerprint acquisition method is improved.
It should be noted that, if one functional area is covered or sufficient space cannot be provided for fingerprint identification, the third fingerprint identification area may be selected to cover at least one functional area whose user usage frequency is less than the preset threshold value based on the layout of the current application interface.
In summary, according to the fingerprint collection method provided in the embodiments of the present invention, a triggerable control corresponding to a fingerprint identification is triggered and applied in a terminal, when entering a corresponding fingerprint identification scenario, a function area corresponding to the triggerable control is displayed on a current application interface, and when the function area overlaps with a second fingerprint identification area, a first fingerprint identification area different from the second fingerprint identification area is selected and a fingerprint identification function of the first fingerprint identification area is turned on, and a fingerprint identification function of the second fingerprint identification area is turned off. The purpose of dynamically adjusting the fingerprint identification area to the position where the touch control function is not responded is achieved, if the first fingerprint identification area meeting the conditions cannot be selected, the third fingerprint identification area is selected to cover at least one function area with the user use frequency smaller than the preset threshold, and the fingerprint identification function of the third fingerprint identification area is started. The method achieves the purpose of dynamically adjusting the fingerprint identification area under the condition that the current interface utilization rate of the touch screen reaches the peak value, and improves the applicability of the fingerprint acquisition method.

The display unit 740 may include a display panel 741, and optionally, the display panel 741 may be configured in the form of an LCD or an Organic Light-Emitting Diode (OLED).
It should be noted that the touch panel 731 can cover the display panel 741 to form a touch display screen, and when the touch display screen detects a touch operation on or near the touch display screen, the touch display screen is transmitted to the processor 760 to determine the type of the touch event, and then the processor 760 provides a corresponding visual output on the touch display screen according to the type of the touch event.
The touch display screen comprises an application program interface display area and a common control display area. The arrangement modes of the application program interface display area and the common control display area are not limited, and can be an arrangement mode which can distinguish two display areas, such as vertical arrangement, left-right arrangement and the like. The application interface display area may be used to display an interface of an application. Each interface may contain at least one interface element such as an icon and/or widget desktop control for an application. The application interface display area may also be an empty interface that does not contain any content. The common control display area is used for displaying controls with high utilization rate, such as application icons like setting buttons, interface numbers, scroll bars, phone book icons and the like.
The processor 760 is a control center of the terminal, connects various parts of the entire handset using various interfaces and lines, and performs various functions of the terminal and processes data by operating or executing software programs and/or modules stored in the first memory 721 and calling data stored in the second memory 722, thereby integrally monitoring the terminal.
