Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

It should be appreciated that reference throughout this specification to "an embodiment of the present application" or "an embodiment described previously" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present application. Thus, the appearances of the phrases "in the embodiments of the present application" or "in the embodiments" in various places throughout this specification are not necessarily all referring to the same embodiments. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the embodiments of the present application, the sequence numbers of the above-mentioned processes do not mean the execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application. The above-mentioned serial numbers of the embodiments of the present application are merely for description and do not represent the merits of the embodiments.

In a case where no specific description is given, the electronic device may execute any step in the embodiments of the present application, and the processor of the electronic device may execute the step. The embodiment of the present application does not limit the sequence of the steps executed by the electronic device. Any step in the embodiments of the present application may be executed by the electronic device independently, that is, when the electronic device executes any step in the following embodiments, the electronic device may not depend on the execution of other steps.

The embodiment of the application provides a biological information input method, which is applied to electronic equipment, and as shown in fig. 1, the method comprises the following steps:

step 101: a contact area is obtained where the object contacts the acquisition area.

The electronic device may be any device with data processing capabilities, such as a server, a mobile phone, a tablet computer, a laptop computer, a palmtop computer, a personal digital assistant, a portable media player, a smart wearable device, a smart speaker, a navigation device, a wearable device, a smart band, a medical device, a pedometer, a digital TV, or a desktop computer. In the embodiment of the present application, the electronic device may be a mobile phone.

In one embodiment, the biometric information may be a fingerprint and the object may be a finger. The electronic device may enter the biometric information based on a fingerprint sensor having a fingerprint acquisition function. The fingerprint sensor may be an off-screen fingerprint sensor, which may include a capacitive fingerprint sensor, an optical fingerprint sensor, or an ultrasonic fingerprint sensor. The electronic device may have a display screen, and the acquisition region may be set at a designated region of the display screen.

The electronic device can be based on the operation of the user, for example, the user can open a fingerprint option for setting the application program, an interface for inputting biological information is displayed based on the operation of the user, the interface can be displayed with a collection area, the collection area is specifically a fingerprint input area, namely an area corresponding to the fingerprint sensor under the screen, the interface can further include indication information for indicating the user to operate the collection area, and therefore the user can perform corresponding operation aiming at the collection area after seeing the indication information. For example, the interface may display an indication to scroll the finger across the collection area so that the user can scroll the finger across the collection area; for another example, the interface may display the indication information of the finger scrolling longitudinally on the acquisition area, so that the user may scroll the finger longitudinally on the acquisition area; for another example, the interface may display an indication that the finger has scrolled one turn around the reference position on the acquisition region, so that the user can scroll the finger one turn around the reference position after pressing the acquisition region, wherein the reference position may be a certain point or a certain region in the pressing region of the finger when pressing the acquisition region. The embodiment of the application is not limited to this, and the interface may also display other indication information as long as the indication information is used to indicate the user to perform a scrolling operation in the collection area.

In the process of scrolling the finger, the interface may further display instruction information instructing the user to scroll in the next direction based on the scrolling operation of the acquired finger or the fingerprint information of the acquired finger, that is, in the process of performing one operation in the acquisition area by the user, the interface may display different instruction information.

The number of contact areas acquired by the electronic device may be plural. The off-screen fingerprint sensor may periodically acquire the contact area of the object with the acquisition area as the object scrolls through the acquisition area, so that multiple contact areas of the object may be available. The period for obtaining the contact area may be in a range between 50 milliseconds and 1 second, for example, the period may be 50 milliseconds, 100 milliseconds, 500 milliseconds, or 1 second. Taking the period as 100 milliseconds for example, after a user places a finger on the acquisition area, the finger does not leave the surface of the sensor, and is inclined towards all directions, so that various possible gestures of contacting the sensor in the future are simulated, generally only 2-3 seconds are needed, all the possible gestures can be completely done by the user, and then within 2-3 seconds, 20-30 contact areas can be obtained by the electronic equipment, so that 20-30 fingerprint samples can be obtained.

The length and width of the acquisition area are both greater than 1 cm. For example, the acquisition region may each be 1.5cm, 2cm, 2.5cm, 3cm, or 3.5cm in length and width. Further, the length and width of the acquisition region may be 3cm or more. In the present embodiment, the length and width of the acquisition region are both 3 cm.

In another embodiment, the biometric information may be an iris and the contact region may be a region in the capture region of the smart eyewear. Alternatively, the biological information may be skin information of a location and the contact area may be an area in an acquisition area of the medical device.

Step 102: an effective entry area is determined based on the contact area.

The effective recording area determined by different contact areas is different. The electronic device can acquire the plurality of contact areas, and can determine a plurality of valid entry areas corresponding to the plurality of contact areas, for example, 20 contact areas determine 20 valid entry areas. The effective recording area is included in the contact area.

The positions of different effective recording areas on the acquisition area are different, and no intersection exists between any two effective recording areas understandably. It should be understood that when the contact areas obtained twice are not changed, that is, when the contact areas of the object and the acquisition area obtained by the electronic device last time and last time are not changed, the electronic device may determine that the valid entry area corresponding to the contact area obtained last time is empty.

In the process of the rolling operation that an object contacts the acquisition area and is maintained at the contact position, the under-screen fingerprint sensor continuously acquires the contact area, and when the contact area is acquired for the first time, the contact area acquired for the first time is used as an effective recording area; when the contact area is acquired for the second time, taking the area of the contact area acquired for the second time except the overlapping area of the contact area acquired for the first time as an effective recording area; when the contact area is acquired for the third time, in one embodiment, the overlapping area of the contact area acquired for the third time except the contact area acquired for the second time is used as the effective recording area, in which case the scrolling direction of the finger is not changed, for example, the finger scrolls to the right; in another embodiment, the contact area acquired for the third time is used as the effective entry area, except for the overlapping area with the contact area acquired for the second time and the overlapping area with the contact area acquired for the first time, in which case the direction of scrolling of the finger is constantly changing, e.g., scrolling of the finger around the reference position; by analogy, the under-screen fingerprint sensor continuously acquires an effective input area which is completely different from the position of the obtained effective input area, namely a new effective input area without intersection with the obtained effective input area until the preset time is reached, or the object leaves the acquisition area, or a complete biological information matching template can be obtained based on the acquired effective input area.

Step 103: and extracting effective biological characteristic information based on the effective input area.

If the contact area changes within the controllable range, different effective biological characteristic information is extracted based on different effective recording areas.

The electronic equipment can acquire the biological characteristic information of the contact area based on the fingerprint sensor under the screen, so that after the effective input area is determined based on the contact area, the effective biological characteristic information can be extracted based on the effective input area. In a plurality of different effective biological characteristic information acquired by the electronic equipment, any two effective biological characteristic information are completely different or have no intersection. In a particular implementation, different valid biometric information may correspond to fingerprints of different regions of the finger.

According to the biological information input method provided by the embodiment of the application, a contact area of an object contacting an acquisition area is obtained; determining an effective recording area based on the contact area; extracting effective biological characteristic information based on the effective input area; if the contact area changes within the controllable range, different effective biological characteristic information is extracted based on different effective recording areas. Therefore, the electronic equipment can extract different effective biological characteristic information based on different effective input areas, so that different biological characteristic information of different position areas of the object can be obtained by the object through one-time contact with the acquisition area, and the biological characteristic input interaction process is simple and short in time.

Based on the foregoing embodiments, the present application provides a biological information entry method, as shown in fig. 2, including the following steps:

step 201: the electronic device obtains a contact area where the object contacts the acquisition area.

Prior to step 201, the electronic device may perform the following steps: and displaying and outputting indication information for prompting the scrolling mode of maintaining the object at the contact position.

The indication information displayed for output may be text information, for example, the text information may be "please place a finger in the capture area and scroll the finger". In another embodiment, the indication information displayed for output may be a dynamic map, for example, a dynamic map on the display screen may be displayed in which a finger is placed in the capture area and scrolled. In another embodiment, the indication information displayed and output may be a combination of text information and dynamic diagrams. In other embodiments, the electronic device may output the indication in speech.

Step 202: the electronic device determines an effective entry area based on the contact area.

Step 203: the electronic device extracts valid biometric information based on the valid entry region.

In the embodiment of the application, the change of the contact area is used for keeping unchanged the reference position of one input for representing the object within the controllable range, and the reference position is in the overlapping area of the acquired contact areas.

In the embodiment of the present application, one input of the object is a scroll operation in which the object is maintained at the contact position. The scroll operation may be a scroll operation of up, down, left, and right, which is maintained at the contact position, or a scroll operation of one rotation. The contact position may be determined based on the first obtained contact area, and in one embodiment, during one input of the object, the electronic device may determine the center position of the contact area as the contact position when obtaining the first contact area. Alternatively, the contact position may be the same position as the reference position.

The one-time input of the reference position of the object is not changed, which may be understood as an input operation of the object around the reference position, and the reference position may be one point or may be one area. In a specific implementation scenario, the object may be scrolled around a reference position. It should be understood that the contact position acquired by the electronic device may or may not be in contact with the reference position. The embodiment of the application can understand one-time input of the object as follows: the input of an object from the beginning of contact with the acquisition area to the leaving of the acquisition area is called an input, during which the finger can be moved over the acquisition area, but it is ensured that the finger is in constant contact with the acquisition area. In an embodiment, in the process of one input, the finger may be pressed against the reference position all the time, that is, the contact areas acquired by the electronic device all include the reference position, if the electronic device acquires that a certain contact area does not include the reference position, the range of motion of the representative finger is too large, the electronic device may interrupt the operation of receiving the finger, and determine the operation that has been received as one operation of the finger.

In the embodiment of the application, the current contact area comprises an overlapping area and a change area with the last contact area, and the effective recording area of the current contact area is the change area.

In one embodiment, the contact area where the object contacts the acquisition area is the first active entry area. The first valid entry area may be a contact area first acquired by the off-screen fingerprint sensor.

After the object is maintained at the contact position and is subjected to rolling operation, the object contacts a region where the contact region of the acquisition region is not overlapped with the first effective input region, and the region is a second effective input region; wherein the contact location is in the first active entry area; the effective recording area comprises a first effective recording area and a second effective recording area. Further, a region where the contact region of the object contacting the acquisition region does not overlap with the first effective entry region and the second effective entry region is a third effective entry region, and the effective entry region further includes the third effective entry region. Moreover, the effective entry areas may further include a fourth effective entry area, a fifth effective entry area and the like, and the number of the effective entry areas included in the effective entry areas is the same as the number of the contact areas acquired by the electronic device. The first effective recording area, the second effective recording area, the third effective recording area, the fourth effective recording area and the fifth effective recording area are all included in the effective recording areas.

Referring to fig. 3, (a) in fig. 3 is a position of the finger 4 in the capture area 3 when the finger 4 comes into contact with the capture area 3 and has a first contact area. Referring to (b) and (c) in fig. 3, fig. 3 (b) and (c) are bottom views viewed from below the acquisition region, in (b), there is a first contact region between the finger 4 and the acquisition region 3 on the acquisition region 3, the region 31 may correspond to a first characteristic portion of the finger, and the first characteristic portion may be obtained by the electronic device based on the first contact region. After the finger is rolled towards the right frame of the electronic device, the electronic device may obtain biometric information corresponding to the second contact region. In fig. 3 (b), the electronic device may obtain the reference position M based on the first contact area, where the reference position M is the central position of the first contact area, and it should be understood that in other embodiments, the reference position may be other than the central position, for example, the other position may be a certain position within the central area of the first contact area, or the reference position may also be a reference area determined based on the first contact area, for example, the reference area may be the central area of the first contact area, and the reference area may be any conceivable shape, which is not limited herein. Referring to fig. 3 (c), there is a second contact area between the finger 4 and the capture area 3 on the capture area 3, and the area 32 may correspond to a second characteristic portion of the finger, that is, when the finger is at the position in (c), a portion of the first characteristic portion (corresponding to the area 31) and a second characteristic portion (corresponding to the area 32) of the finger 4 may be obtained from the second contact area, and the area 32 is obtained from a variation area of the second contact area relative to the first base area. When the finger 4 is moved to the position in (c), the area that the electronic device can capture still includes the reference position M. In this embodiment, the reference position of one input may be unchanged, and no matter how the object scrolls in the acquisition area, the contact area acquired by the electronic device should include the reference position, that is, the scrolling of the object in the acquisition area may be a small-range scrolling.

Referring to fig. 3 (d), as the finger rolls on the capture area, when the finger rolls to the right, left, up and down along the first contact position, the electronic device can obtain 5 characteristic portions of the finger 4, where the 5 characteristic portions correspond to the areas 31-35, respectively. (d) The regions 31-35 shown in (a) may be closer together or further apart, and in one possible case, two adjacent regions may meet.

In one possible embodiment, the valid entry area determined by the electronic device based on the contact area may be the areas 31-35, such that the electronic device obtains valid biometric information for the areas 31-35. In this case, since the acquired regions 31-35 include features of the finger in different directions, a fingerprint matching template of the finger can also be obtained. By obtaining valid biometric information for the regions 31-35, three-dimensional feature information for the finger can be obtained, making the resulting fingerprint matching template a 3D template.

The electronic device can extract effective biometric information corresponding to the effective entry area by acquiring the image of the acquisition area. Specifically, step 203 may be implemented by the following steps a to C:

step A: the electronic equipment acquires image information of the acquisition area.

In an implementation manner, a pressure sensor may be disposed below the acquisition area, the electronic device may determine pressure information received by the acquisition area based on the pressure sensor, and when it is determined that the pressure information is greater than a first threshold value, the under-screen fingerprint sensor may be controlled to start acquiring image information of the acquisition area, so as to acquire the image information of the acquisition area. In another embodiment, the electronic device may acquire the area of the contact region, and when the area exceeds the second threshold, the off-screen fingerprint sensor may be controlled to start acquiring the image information of the acquisition region. The visual information may be an image.

The electronic equipment can control the under-screen fingerprint sensor to periodically acquire the image information of the acquisition area so as to acquire a plurality of image information, and in the process of acquiring the plurality of image information, a user can also roll a finger on the contact area so as to acquire a plurality of different image information.

The image information acquired twice in the vicinity of each other may be first image information and second image information, the first image information corresponds to a first contact area of the object in the acquisition area, the second image information corresponds to a second contact area of the object in the acquisition area, the first contact area and the second contact area have a coincidence area, the electronic device may determine whether first sub-image information corresponding to the coincidence area in the first image information is the same as second sub-image information corresponding to the coincidence area in the second image information, and when it is determined that the first sub-image information and the second sub-image information are the same, determine that the operation of the object is a scrolling operation, otherwise, determine that the operation of the object is a non-scrolling operation, where the non-scrolling operation is, for example, a sliding operation.

The electronic equipment can continuously acquire the image information of the acquisition area when the operation of the object is determined to be the rolling operation, otherwise, the information that the user operation is the non-rolling operation is output, so that the user can determine that the current operation is the misoperation after seeing the information, the current operation can be stopped, and the next correct operation can be carried out. Therefore, the electronic equipment can enter the fingerprint of the user only when the operation of the finger of the user on the acquisition area is determined to be rolling operation, otherwise, the fingerprint of the user is not entered, so that the mode that the fingerprint of the user is matched with the template through the acquired image information is simple, the misoperation of the user can be avoided, and the condition that the fingerprint cannot be entered is caused.

In the following, an operation of the finger in the capture area will be described with reference to fig. 4, where in (a), the finger starts to contact the capture area and has a first contact area, the center position of the first contact area is determined as the reference position M, the reference position M in fig. 4 may be the same as the reference position M in fig. 3, and the image information corresponding to the first contact area is (a). Where (a) in fig. 4 may correspond to (a) in fig. 3. And then the finger can roll towards the left frame until the finger reaches the position in (B), and the contact area of the finger and the acquisition area can be a second contact area, and the image information corresponding to the second contact area is (B). And then the finger can roll towards the direction of the right frame until the finger reaches the position in the step (C), and the contact area of the finger and the acquisition area can be a third contact area, and the image information corresponding to the third contact area is (C). And then the finger can return to the finger position in the step (A), and then the finger is rolled towards the upper frame to reach the position in the step (D), wherein the contact area of the finger and the acquisition area is a fourth contact area, and the image information corresponding to the fourth contact area is (D). And continuing to scroll the finger in the direction of the lower frame until the position in the step (E) is reached, wherein the contact area of the finger and the acquisition area is a fifth contact area, and the image information corresponding to the fifth contact area is in the step (E). That is, the finger may be rolled in up, down, left, and right directions after contacting the collection area.

In the following, another motion of the finger in the capture area is described based on fig. 5, in (a), after the electronic device obtains the first contact area and the image information (a), the finger can be sequentially rotated and rolled for one circle, so as to sequentially move to the positions of (C), (E), (B), and (D), and obtain the images (C), (E), (B), and (D), respectively. It should be noted that the arrows in fig. 3 and 4 characterize the scrolling direction of the finger from the current position to the next position.

As can be seen from fig. 4 and 5, no matter how the finger is scrolled on the capture area, the motion of the finger is scrolling on the reference position, and from the perspective of the electronic device, the contact area of the captured finger and the capture area of the electronic device should include the reference position M. While the reference position of one input of the finger is not changed, it may be a scroll operation in which the finger constantly presses the reference position and on the acquisition region.

The embodiment of the application does not limit the rolling condition of the finger in the acquisition area, for example, in other realizable scenes, the finger can roll in as many directions as possible after contacting the acquisition area, and various possible gestures of contacting the acquisition area in the future are simulated, so that the electronic equipment can acquire enough fingerprint samples, and further more accurate fingerprint matching templates are obtained.

And B: the electronic equipment acquires the sub-image information corresponding to the effective input area from the image information.

In one embodiment, the sub-image information corresponding to the current contact area is a changed portion of the currently obtained image information from the previously obtained image information or the already obtained image information. For example, referring to fig. 4 or fig. 5, in (a), the electronic device determines that the first contact area is the valid entry area, so as to determine that the sub-image information corresponding to the first contact area is the fingerprint image acquired for the first time. In (B), the electronic device determines that the second contact area is a valid entry area of the second contact area excluding the overlapping area of the first contact area and the second contact area, and determines that the sub-image information corresponding to the second valid entry area is a portion of the second acquired fingerprint image excluding the first acquired fingerprint image. Similarly, in (E), the electronic device determines that the fifth contact area excludes the overlapping area with the first contact area, the overlapping area with the second contact area, the overlapping area with the third contact area, and the overlapping area with the fourth contact area, and obtains an effective entry area of the fifth contact area, wherein when two contact areas do not overlap, the overlapping area is determined to be empty, and the subpicture information corresponding to the fifth effective entry area excludes the portion of the fingerprint image acquired for the fifth time. Therefore, the electronic equipment determines that the sub-image information acquired each time is not intersected with the sub-image information already acquired.

And C: the electronic device obtains effective biological characteristic information based on the sub-image information.

The electronic device can analyze each obtained sub-image information to obtain each effective biological information corresponding to each sub-image information. In the analysis process, the electronic device may perform noise reduction, filtering, and other processing on each piece of sub-image information.

When the electronic device is to realize the fingerprint identification function, a complete biometric information matching template is generally generated in advance. A complete biological information matching template not only comprises biological information of a central area of an object, but also comprises biological information of an edge area of the object, so that the object can unlock, pay or log in the electronic equipment at different positions, and the one-time success rate of biological information identification can be improved. In one embodiment, the electronic device may also perform the following step 204.

Step 204: if the obtained object leaves the acquisition area, the electronic equipment takes different effective biological characteristic information extracted from a plurality of different effective input areas as a biological information matching template.

The electronic equipment can splice different effective biological characteristic information to obtain a biological information matching template. The biometric information matching template may be a union of a plurality of different valid biometric information.

The biometric information matching template may be a fingerprint matching template. In one embodiment, the fingerprint matching template may correspond to the fingerprint feature information in areas 31-35 in fig. 3 (d), i.e. the fingerprint matching template includes 5 features on the finger, and in these 5 features, two adjacent features may or may not be in contact. In another embodiment, the fingerprint matching template may be determined by: fingerprint information of contact areas of the finger and the acquisition area in (a) - (E) of fig. 4 is acquired, and overlapping parts of any two adjacent acquired fingerprint information are removed, so that a fingerprint matching template is obtained. The obtained fingerprint matching template comprises fingerprint information of the middle part, the upper part, the lower part, the left part and the right part of the finger, so that the fingerprint matched with the fingerprint matching template can be accurately identified in the subsequent unlocking or payment process of the obtained 3D fingerprint template.

After the electronic equipment obtains the fingerprint matching template, the fingerprint matching template can be stored in the electronic equipment, so that when a user unlocks, pays or decrypts by using the fingerprint, the electronic equipment can match the collected current fingerprint with the fingerprint matching template.

For example, when a user opens a first type of application by using a fingerprint, the user may place a finger in the acquisition area, the electronic device may obtain first current fingerprint information based on a contact area between the finger and the acquisition area, and match the first current fingerprint information with the fingerprint matching template, if the matching is successful, the first type of application is opened, otherwise, the first type of application is not opened. When the user opens the second type of application by using the fingerprint, the user can place the finger in the acquisition area and roll the finger, so that the electronic equipment can obtain second current fingerprint information based on the rolling of the finger on the acquisition area and match the second current fingerprint information with the fingerprint matching template, if the matching is successful, the second type of application is opened, otherwise, the second type of application is not opened.

For example, when the electronic device is in the locked state, the electronic device may be switched from the locked state to the unlocked state by obtaining feature information of a fingerprint of a finger in the fingerprint acquisition area to match with a stored fingerprint template (which may be a 3D fingerprint template) entered according to the above-described embodiment, and if a first threshold is met, unlocking is performed if a first matching requirement is met. The electronic device is in a payment state (for example, the payment application is called, that is, a payment function module of a payment treasure, a WeChat application, or a bank application is called), matching may be performed by obtaining feature information of the fingerprint of the finger in the fingerprint collection area with a stored fingerprint template (which may be a 3D fingerprint template) entered according to the above-described embodiment, and if a second threshold is met, a second matching requirement is met, and a successful authentication result is fed back to the payment function module, so that the electronic device payment application completes a payment transaction based on the authentication result. It should be noted that the first threshold is smaller than the second threshold, and specifically, the second matching requirement is higher than the first matching requirement. For a user who operates the electronic device correspondingly, when the electronic device is in a locked state, the fingerprint template is a 3D fingerprint template (namely, the fingerprint input of all directions (front, left, right, upper edge and lower edge) of one finger), so that the user can authenticate the feature information of the fingerprint acquired based on the fingerprint and the matching template as long as the finger contacts the acquisition area based on the current holding posture for holding the electronic device, and the unlocking can be realized as long as the feature point meets the first threshold value. That is, as long as the user who enters the electronic equipment touches the acquisition area, the unlocking effect can be achieved as long as the user holds the electronic equipment in any holding posture. In addition, the electronic device is in the payment state, since the fingerprint template is a 3D fingerprint template and needs to satisfy the second matching requirement, the electronic device can be authenticated, that is, the user needs to perform some relatively complicated actions to satisfy the feature points (i.e., the second threshold) required by the second matching requirement when inputting the finger in the fingerprint collection area. For example, the user needs to touch a finger to the fingerprint acquisition area to enable the fingerprint acquisition module to acquire a first fingerprint feature point; then, the user needs to keep the body of the finger unchanged relative to the electronic device and applies force to the left side of the user to slightly deflect the finger to the left so that the fingerprint acquisition module acquires the second fingerprint feature point, and the first feature point and the second feature point are compared with the second threshold value of the fingerprint template together to determine whether the authentication passes or not. Therefore, the safety of the identity authentication of the electronic equipment in the payment state is improved. Certainly, in the embodiment of the application, fingerprint collection of the user's finger in the payment state is not limited to that the user needs to keep the main body of the finger unchanged relative to the electronic device and the user applies force to the left side to slightly deflect the finger to the left, that the user needs to keep the main body of the finger unchanged relative to the electronic device and to the right, and that the user applies force upwards or downwards to slightly deflect the finger in a corresponding direction, and that the user needs to keep the main body of the finger unchanged relative to the electronic device and applies force in a clockwise or counterclockwise direction to make the second feature point include feature points on the left side, the upper edge, and the right side of the finger.

Referring to fig. 6, the contact between the finger and the collection area is in any direction or any position, the finger may also roll in any direction on the collection area, and the dotted line in fig. 6 represents a position where the finger can be replaced, and no matter how the finger contacts the collection area, the electronic device may obtain the fingerprint feature information of the contact area and the valid fingerprint feature information corresponding to the valid recording area, and match the obtained fingerprint feature information with the fingerprint matching template.

When the first type of application is started, the electronic device can prompt a user of a finger pressing mode, and when the second type of application is started, the electronic device can prompt the user of a finger pressing and scrolling mode. And no matter the user presses or presses and rolls the finger on the acquisition area, the electronic equipment can acquire the fingerprint characteristic information of the finger, the acquired fingerprint characteristic information is matched with the fingerprint matching template, if the matching degree is greater than a threshold value, the characteristic matching is successful, and otherwise, the characteristic matching is failed. In one embodiment, the matching of the fingerprint feature information and the fingerprint matching template may be matching feature points in the fingerprint feature information and feature points in the fingerprint matching template. It can be understood that the fingerprint feature information obtained by pressing and rolling the finger on the capture area is greater than the fingerprint feature information obtained by pressing the finger on the capture area. The degree of security of the second type of application may be higher than the degree of security of the first type of application. For example, the second type of application may be a payment type application or an application such as an open target application program, and the first type of application may be an unlock type application.
