[0057] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The following description is made with reference to the accompanying drawings in which like reference numerals represent like elements, unless the context of use indicates otherwise. The following description of exemplary embodiments is not representative of all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0058] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the present disclosure. As used in this disclosure and the appended claims, the singular forms "a," "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0059] It will be understood that, although the terms first, second, third, etc. can be used herein to describe various information, these terms are not intended to denote a temporal or chronological order. Rather, these terms are used only to distinguish different sets of information from one another. For example, a first information can be termed a second information, and similarly, a second information can also be termed a first information, without departing from the scope of the present disclosure. Depending on the context, the word "if' as used herein can be interpreted to mean "when" or "in response to determining" or "in response to a determination".

[0060] In the related art, the fingerprint collection module 1 of the electronic device 100 is usually located at the bottom of the panel, for example Figure 1 As shown, the fingerprint collection module 1 can be located at the bottom of the home key, so that the user can complete the fingerprint collection and identification function when pressing the home key. Then, the fingerprint sensing area corresponding to the fingerprint collection module 1 is usually equivalent to the key area of the home key, so that the fingerprint sensing area can be clearly distinguished from other areas of the electronic device 100, and the user can accurately identify the fingerprint identification area and perform the fingerprint identification operation.

[0061] However, whether it is the home key or the fingerprint sensing area, a part of the area at the bottom of the panel of the electronic device 100 needs to be occupied, so it cannot be applied to arrange the screen, which affects the further increase of the screen-to-body ratio of the electronic device 100.

[0062] Therefore, in order to improve the panel utilization rate and increase the screen-to-body ratio of the electronic device 100 using the technical solution as shown in Figure 1 As shown, the fingerprint collection module 1 is arranged at the bottom of the panel of the electronic device 100, and the fingerprint sensing area corresponding to the fingerprint collection module 1 is arranged at the bottom of the screen of the electronic device 100. Figure 2As shown, the related art proposes to move the fingerprint collection module 1 to the backplane of the electronic device 100 to avoid occupying the panel space of the electronic device 100. However, when the fingerprint collection module 1 is located at the back of the electronic device 100, the user needs to manually flip the electronic device 100 to be able to see the fingerprint collection module 1, especially when the user cannot hold the electronic device 100, which may cause the fingerprint recognition operation to be unable to be implemented, resulting in the application scenario of fingerprint recognition being limited.

[0063] To this end, as shown in Figure 3 the related art further proposes to integrate the fingerprint collection module 1 at the touch display screen of the electronic device 200, and then the fingerprint recognition area 10 corresponding to the fingerprint collection module 1 is located within the display area 20 corresponding to the touch display screen. If the fingerprint sensing area 10 can cover the entire display area 20, the user can perform the fingerprint recognition operation at any position within the display area 20; however, due to the internal space, production cost and other factors of the electronic device 200, it is more likely to implement partial fingerprint recognition within the display area 20 of the electronic device 200, i.e. the fingerprint sensing area 10 only covers part of the display area 20, for example Figure 3 the fingerprint sensing area 10 is located at the bottom area of the display area 20 and does not cover the middle and upper areas; of course, the fingerprint sensing area 10 can also be located at the middle or upper area of the display area 20, and the present disclosure does not limit this.

[0064] However, in order to avoid affecting the display function of the display area 20, it is not possible to add indication information of the fingerprint sensing area 10 on the electronic device 200, so that it is difficult for the user who has not used or rarely uses the electronic device 200 to accurately distinguish the fingerprint sensing area 10 from the display area 20, causing the fingerprint recognition operation to be unable to be completed or reducing the execution efficiency of the fingerprint recognition operation.

[0065] Therefore, the present disclosure proposes a fingerprint collection position prompting scheme for the above Figure 3 electronic device 200, i.e. the technical solution of implementing partial fingerprint recognition within the display area 20, to solve the above technical problems existing in the related art. The technical solutions of the present disclosure will be described below in conjunction with the embodiments.

[0066] Figure 4 is a flowchart of a fingerprint collection position prompting method according to an exemplary embodiment, as shown in Figure 4 the method is applied to an electronic device (for example Figure 3 the electronic device 200 as shown), and can include the following steps:

[0067] In step 401, a user operation on the electronic device is detected.

[0068] In the embodiment, based on the detected user operation, it can be determined that the user has an operation intention for the electronic device, including whether the user needs to perform a fingerprint identification operation. For example, the operation intention shown by the user operation can be identified by at least one of the following ways:

[0069] In an embodiment, the user operation can be determined when it is detected that the spatial posture information of the electronic device changes; further, when the spatial posture information changes by a preset change, it is determined that the user operation matches the predefined collection trigger operation, i.e., the user has an intention of fingerprint identification operation. The spatial posture information can include angular velocity information, acceleration information, etc. of the electronic device, which can be detected by a gyroscope or other sensors built in the electronic device. Of course, the spatial posture information can also include other parameters and be detected by other sensors built in the electronic device, such as positioning information collected by a GPS or Beidou positioning chip built in the electronic device, image change information collected by a camera built in the electronic device, audio change information collected by a microphone built in the electronic device, etc., which can all be the spatial posture information.

[0070] The spatial posture information will change with the change of the spatial state of the electronic device. However, in many scenarios, the change of the spatial state of the electronic device is not intended by the user (for example, in the process of the user walking, the electronic device presents irregular changes in the spatial state), or the change of a certain spatial state of the electronic device cannot be confirmed as the user needs to operate the electronic device (for example, the change of the spatial state when the user holds the phone to perform a "shake" action). Therefore, by matching the change of the collected spatial posture information with a preset change (i.e., the electronic device records the change of the spatial posture information when the user has an intention of fingerprint identification operation), it can be determined whether the user needs to operate the corresponding electronic device, so as to autonomously and accurately determine the operation intention of the user for the electronic device, which helps to simplify the user operation and improve the efficiency of the fingerprint identification operation. When the spatial posture information of the electronic device changes by a preset change based on the user operation, it means that the user holds the electronic device and completes a preset action, such as "turning over", "lifting up", etc., to show the user's intention of fingerprint identification operation for the electronic device.

[0071] In another embodiment, the user operation can be determined when a first trigger instruction for a physical button of the electronic device is received; further, when the first trigger instruction is for a preset physical button on the electronic device, it can be determined that the user operation matches the predefined collection trigger operation. The physical button can be a power button, a volume button, a Home button, etc. of the electronic device, and the disclosure does not limit this; the trigger operation of the physical button can include pressing, touching or other forms, and the disclosure does not limit this. The preset physical button can include a predefined single physical button or a combination of multiple predefined physical buttons, which can be predefined by the system of the electronic device or customized by the user according to actual needs.

[0072] In yet another embodiment, the user operation can be determined when a second trigger instruction for a virtual button on a function page displayed by the electronic device is received; further, when the second trigger instruction is for a preset virtual button on a preset function page, it can be determined that the user operation matches the predefined collection trigger operation. The preset function page can be any predefined function page, such as a payment confirmation page, an authorized login page or other function pages requiring user authorization, and the virtual button can include a predefined virtual button on the function page, such as "fingerprint payment" on the payment confirmation page, "confirm login" on the authorized login page, etc. The "preset function page" and "preset virtual button" can be predefined by the system of the electronic device or customized by the user according to actual needs.

[0073] Of course, the detection methods described in the above various embodiments can also be combined. For example, when it is detected that the spatial posture information of the electronic device has a preset change and a first trigger instruction for a preset physical button is received, it is determined that the user operation matches the predefined collection trigger operation; for another example, when it is determined that a first trigger instruction for a preset physical button is received and a second trigger instruction for a preset virtual button in a preset function page is received, it is determined that the user operation matches the predefined collection trigger operation. Other combination methods are not listed here.

[0074] It should be noted that when the above multiple detection methods are combined, the disclosure does not limit the order of occurrence between each detection method. For example, assuming that the detection method adopted is: when it is determined that the first trigger instruction for the preset physical key is received, and the second trigger instruction for the preset virtual key in the preset function page is received, it is determined that the user operation matches the pre-defined collection trigger operation, then the first trigger instruction can be received after the second trigger instruction is received, or the second trigger instruction can be received after the first trigger instruction is received, or the first trigger instruction and the second trigger instruction can be received at the same time, and the disclosure does not limit this.

[0075] In the embodiment, from the perspective of the user, the matching of the user operation and the pre-defined collection trigger operation indicates that the user has completed a preset action, such as a "turning over", "lifting up" and the like of the electronic device, and a "pressing", "clicking", "touching" and the like of the physical key or the virtual key; and from the perspective of the electronic device, the operation information corresponding to the user operation is matched with the operation information of the pre-defined collection trigger operation, such as the matching between the "turning over" angle and the "turning over" angle of the pre-defined collection trigger operation, the matching between the key information of the triggered physical key or virtual key and the key information corresponding to the pre-defined collection trigger operation, and the like.

[0076] In step 402, when the user operation matches the pre-defined collection trigger operation, the fingerprint sensing area is shown in the display area to indicate the user to perform a fingerprint collection operation in the fingerprint sensing area.

[0077] In an embodiment, the fingerprint collection module on the electronic device can set the fingerprint collection function to an always-on state.

[0078] In another embodiment, the electronic device can set the fingerprint collection module to an always-off state, and temporarily turn on the fingerprint collection function of the fingerprint collection module to minimize the power loss caused by the fingerprint collection module and prolong the endurance time of the electronic device; wherein the fingerprint collection function can have multiple opening conditions, which are illustrated as follows:

[0079] In one case, when the user operation matches the pre-defined collection trigger operation, the fingerprint collection function of the fingerprint collection module can be turned on within a preset time window. The preset time window refers to a pre-defined time length, such as 3s, 5s, etc.; the time length can be defined by the system of the electronic device, or customized by the user. After the preset time window expires, the electronic device can actively turn off the fingerprint collection function of the fingerprint collection module.

[0080] When the user operation matches the predefined acquisition trigger operation successfully, the electronic device determines that the user has the intention to perform the fingerprint identification operation, and the user should normally perform the fingerprint identification operation immediately or after a short interval. Therefore, the electronic device displays the fingerprint sensing area and starts the fingerprint acquisition function within a preset time window, so that the user can successfully perform the fingerprint identification operation. When the user operation matches the predefined acquisition trigger operation, the electronic device can simultaneously display the fingerprint sensing area and start the fingerprint acquisition function, or can display the fingerprint sensing area and start the fingerprint acquisition function after a preset time interval, for example, the preset time interval can be 0.5 seconds or other time intervals, to match the reaction delay of the user after seeing the displayed fingerprint sensing area (the time interval between the actual display of the fingerprint sensing area and the user seeing the fingerprint sensing area) and the action delay (the time interval between the user seeing the fingerprint sensing area and the user performing the fingerprint identification operation), so as to meet the operation requirements of the user and reduce the power consumption of the fingerprint acquisition module as much as possible.

[0081] In another case, when the fingerprint sensing area is in the displayed state (i.e., the user can view the fingerprint sensing area in the display area), if a user touch operation on the display area is detected, the electronic device can start the fingerprint acquisition function of the fingerprint acquisition module. Since the user must press or approach the fingerprint sensing area with a finger (or other part) when performing the fingerprint identification operation, when the electronic device is equipped with a touch display screen, i.e., the display area has a touch function, the user can be determined to press or approach the fingerprint sensing area with a finger when a user touch operation is detected, i.e., the user indeed needs to perform the fingerprint identification operation. For the case where no user touch operation on the display area is detected, it indicates that a misjudgment of the user's intention may occur, or the user's intention to perform the fingerprint identification operation has changed due to some reasons, so that the fingerprint acquisition function is not started to prevent unnecessary power consumption of the fingerprint acquisition module. Further, the electronic device can close the fingerprint acquisition function after detecting that the user has performed the fingerprint identification operation, or can close the fingerprint acquisition function after the starting time of the fingerprint acquisition function exceeds a preset time length, and the present disclosure does not limit this.

[0082] The user touch operation can be an operation of the user on any position in the display region of the electronic device. In an embodiment, the operation region of the user touch operation can be further determined. When at least a part of the operation region is located in the fingerprint sensing region, it indicates that the user indeed holds or approaches the fingerprint sensing region with a finger, and the electronic device can start the fingerprint collection function of the fingerprint collection module. When the user touch operation is detected but the operation region of the user touch operation is not in the fingerprint sensing region, it indicates that the user touch operation can be caused by accidental touch, and the previous misjudgment of the user's intention can occur, or the user changes the intention of performing the fingerprint identification operation due to some reasons, thereby avoiding starting the fingerprint collection function to prevent the fingerprint collection module from generating unnecessary power consumption. By detecting the user touch operation to determine whether to start the fingerprint collection function of the fingerprint collection module, on the one hand, the power consumption of the electronic device can be saved, and the battery life can be prolonged. On the other hand, the probability of collecting fingerprint information by the fingerprint sensing region is greatly improved, and the internal computing resources are avoided.

[0083] As can be seen from the above embodiment, the method of the present disclosure detects the operation intention of the user to the electronic device, and actively shows the fingerprint sensing region in the display region when it is determined that the user has a fingerprint identification intention, so that the user can accurately distinguish the position of the fingerprint sensing region in the display region and perform a responsive fingerprint collection operation in the fingerprint sensing region, which helps to improve the fingerprint collection efficiency based on the electronic device.

[0084] Based on the fingerprint collection scheme of the present disclosure, it can be applied to various types of electronic devices such as mobile phones, tablet devices, notebook computers, etc., and the present disclosure does not limit this. In the following, the fingerprint collection scheme of the present disclosure is further described and introduced in combination with the user's operation process of the mobile phone.

[0085] Figure 5 Another flowchart of the fingerprint collection position prompting method according to an exemplary embodiment is shown. As shown in Figure 5 The method can include the following steps:

[0086] In step 501, the spatial posture information of the mobile phone is collected.

[0087] In the embodiment, the spatial posture information can include angular velocity information, acceleration information, etc. of the mobile phone, which can be detected by the built-in gyroscope or other sensors of the mobile phone. Of course, the spatial posture information can also include other parameters and be detected by other sensors built in the mobile phone, such as positioning information collected by the positioning chip such as GPS built in the mobile phone; audio information collected by the microphone built in the mobile phone, which can be used as the above-mentioned spatial posture information, and the present disclosure does not limit this.

[0088] In step 502, it is judged whether the spatial posture information of the mobile phone has preset change.

[0089] In the embodiment, if the spatial posture information of the mobile phone has no preset change, it is determined that the user has no fingerprint identification intention, and the step 501 is returned; if the change of the spatial posture information has preset change, it is determined that the user has fingerprint identification intention, and the step 503 is executed. The preset change refers to the change of the spatial posture information recorded in the mobile phone when the user has fingerprint identification intention. When the spatial posture information of the mobile phone has preset change, it can be shown that the user holds the mobile phone to complete preset action, such as "turning over", "lifting up", etc., to embody the user's intention of fingerprint identification operation of the electronic device.

[0090] For example, according to the user's operation habit of the mobile phone, in most cases when the mobile phone is "lifted up", especially in the case that the mobile phone is in the lock screen state, the user is likely to unlock the mobile phone through fingerprint identification operation, so the change of the spatial posture information corresponding to the "lifting up" action can be recorded in the mobile phone in advance to identify the user's operation intention; on the contrary, according to the user's operation habit of the mobile phone, if it is considered that in most cases when the mobile phone is "translated", the user does not need to perform fingerprint identification operation, the change of the spatial posture information corresponding to the "translation" action does not need to be recorded in the mobile phone in advance.

[0091] In one scenario, it is assumed that the user is in the office period and places the mobile phone on the workbench. When the user needs to view data information from the mobile phone, the user usually needs to pick up the mobile phone and lift it up to a suitable reading angle. If the change of the spatial posture information detected by the mobile phone in this process meets the "lifting up" action described above, it indicates that the user has the intention of fingerprint identification operation, so as shown in FIG. 5B, the fingerprint sensing area 10 can be shown in the display area 20 of the mobile phone to prompt the user the position of the fingerprint sensing area 10 in the display area 20. Figure 6

[0092] In another scenario, it is assumed that the user carries the mobile phone to walk or run. Although the mobile phone will also "jolt" and cause the change of the spatial posture information, since the change of the spatial posture information of the mobile phone does not meet the preset action such as "lifting up", "turning over", etc., it is determined that the user has no fingerprint identification operation intention, and the fingerprint sensing area does not need to be displayed.

[0093] In step 503, the fingerprint sensing area is shown in the display area of the mobile phone.

[0094] ​In the embodiment, the fingerprint collection module of the mobile phone can set the fingerprint collection function to a normally closed state, and temporarily open the fingerprint collection function during the display of the fingerprint sensing area, so as to reduce the power consumption caused by the fingerprint collection module. Of course, in another embodiment, the fingerprint collection module can also set the fingerprint collection function to a normally open state, and the present disclosure does not limit this. For the convenience of description, the technical solutions of the present disclosure are described below by taking the fingerprint collection module in the normally closed state as an example.

[0095] In step 504, the fingerprint collection function is opened, and the input user fingerprint is scanned.

[0096] In the embodiment, the fingerprint collection function of the fingerprint collection module can be opened while the fingerprint sensing area is displayed. Alternatively, the fingerprint collection function of the fingerprint collection module can also be opened after the fingerprint sensing area is displayed and a preset time interval is waited, for example, the preset time interval can be, for example, 0.5S or other time intervals; wherein the preset time interval can be set by referring to the time interval between the actual display of the fingerprint sensing area to the user seeing the fingerprint sensing area, and the time interval between the user seeing the fingerprint sensing area to the user performing the fingerprint identification operation, so as to neither affect the user to perform the fingerprint identification operation in the fingerprint sensing area, nor shorten the starting time of the fingerprint collection function as much as possible, and reduce the power consumption of the fingerprint collection module.

[0097] In step 505, it is judged whether the opening time of the fingerprint collection function exceeds the preset time interval.

[0098] In the embodiment, it can be assumed that the preset time interval is t1, and the opening time of the fingerprint collection function is T1, then when T1

[0099] In step 506, it is judged whether the user fingerprint collected during the opening of the fingerprint collection function matches the predefined fingerprint.

[0100] In the embodiment, when the user fingerprint matches the predefined fingerprint, the user verification is passed, and step 507 is performed, and when the user fingerprint does not match the predefined fingerprint, the user verification fails, and step 508 is performed.

[0101] In step 507, the mobile phone is switched from the lock screen state to the unlocked state.

[0102] In this embodiment, after the user verification is successful, the phone state can be switched from the locked state to the unlocked state; similarly, this embodiment can also be applied to switching other states of the phone, all of which belong to switching the phone from a first state to a second state, for example, for the above-mentioned "phone lock" scenario, the first state is the locked state, and the second state is the unlocked state, and for the "private mode" scenario, the first state is the private state (encrypting or hiding the pre-defined private folder), and the second state is the public state (decrypting or normally displaying the pre-defined private folder), and the present disclosure does not limit this.

[0103] In step 508, the display of the fingerprint sensing area is terminated, and the fingerprint scanning is stopped (i.e., the fingerprint collection function is closed).

[0104] Figure 7 According to another exemplary embodiment, a flowchart of a method for prompting a fingerprint collection position is shown. As shown in Figure 7 may include the following steps:

[0105] In step 701, a triggering operation on a physical key of the phone is monitored.

[0106] In this embodiment, the physical key described above can be any physical key on the phone, such as a power key, a volume key, a photographing key, or a Home key, etc., and the present disclosure does not limit this; the triggering operation on the physical key can include any form such as pressing, touching, tapping, etc., and the present disclosure does not limit this.

[0107] In this embodiment, the triggering operation on the physical key can be monitored when the phone is in any state. When the phone is in different states, different operation scenarios and operation purposes can be formed based on the physical key corresponding to the triggering operation; for example, when the phone is in an off-screen state, by monitoring the triggering operation on the power key, the phone can be further unlocked in combination with the subsequent fingerprint identification operation.

[0108] In step 702, it is determined whether the physical key corresponding to the triggering operation is a power key.

[0109] In the embodiment, when the physical key to which the triggering operation is directed is not the power key, step 701 is returned to; when the physical key to which the triggering operation is directed is the power key, step 703 is executed. Of course, in other scenarios, other physical keys can be concerned, such as the volume key, the photograph key, or the Home key, etc. In addition, although the triggering operation directed to the power key is taken as an example in step 702, in addition to the triggering operation directed to a single physical key, the technical solution of the present disclosure is also applicable to the triggering operation directed to a combination of a plurality of predefined physical keys, such as the power key + volume key, the power key + volume key + Home key, etc., and the present disclosure does not limit this.

[0110] In step 703, the fingerprint sensing area is shown in the display area of the mobile phone.

[0111] In the embodiment, step 703 can refer to step 503 in the embodiment shown in Figure 5 The step 503 in the embodiment shown in the embodiment, which will not be repeated here.

[0112] In step 704, when the fingerprint sensing area is in the shown state, it is judged whether the user performs a pressing operation on the touch display screen of the mobile phone.

[0113] In the embodiment, when the pressing operation performed by the user on the touch display screen of the mobile phone is detected, step 705A is executed; when the pressing operation performed by the user on the touch display screen of the mobile phone is not detected, step 705B is executed. The pressing operation can include "clicking", "tapping", "touching", etc. of the user's finger, and the present disclosure does not limit this. The pressing operation of the user in the display area is detected through the touch display screen configured on the mobile phone, the fingerprint identification intention of the user is further determined, the fingerprint collection function of the fingerprint collection module is effectively avoided to be started in the case of user misoperation, and unnecessary function loss of the fingerprint collection module is prevented.

[0114] In step 705A, the fingerprint collection function is started, and the input user fingerprint is scanned.

[0115] In the embodiment, after the fingerprint identification intention of the user is further determined, the fingerprint collection function of the fingerprint collection module is started, and the user fingerprint input during the starting of the fingerprint collection function is collected and scanned, so as to verify the identity of the user.

[0116] In step 705B, it is judged whether the showing duration of the fingerprint sensing area exceeds a preset duration.

[0117] In the embodiment, it can be assumed that the preset time length is t1, the display time length of the fingerprint sensing area is T1, when T1 < t1, that is, the display time length of the fingerprint sensing area does not exceed the preset time length, returning to step 704, when T1 > t1, that is, the display time length of the fingerprint sensing area exceeds the preset time length, terminating the display of the fingerprint sensing area, avoiding the power loss caused by the display of the fingerprint sensing area.

[0118] In step 706, it is judged whether the user fingerprint collected during the fingerprint collection function is turned on matches the predefined fingerprint.

[0119] In the embodiment, when the user fingerprint matches the predefined fingerprint, the user verification is passed, and step 707A is executed, when the user fingerprint does not match the predefined fingerprint, the user verification fails, and step 707B is executed.

[0120] In step 707A, the mobile phone is switched from the lock screen state to the unlocked state.

[0121] In the embodiment, step 707A can refer to step 507 shown in Figure 5 , which will not be described here.

[0122] In step 707B, it is judged whether the display time length of the fingerprint sensing area exceeds the preset time length.

[0123] In the embodiment, it can be assumed that the preset time length is t2, when T2 > t2, that is, the display time length of the fingerprint sensing area has exceeded the preset time length, terminating the display of the fingerprint sensing area and closing the fingerprint collection function of the fingerprint collection module; when T2 < t2, that is, the display time length of the fingerprint sensing area does not exceed the preset time length, continuing to display the fingerprint sensing area in the display area, thereby facilitating the user to perform the fingerprint identification operation again in the case that the user verification fails but there is still a verification request. The user verification failure can be due to the influence of external factors, for example, incorrect fingerprint collection angle or high finger humidity, or can be due to the mismatch between the user identity information and the identity information stored in the mobile phone, which is not limited by the present disclosure.

[0124] It should be noted that: in the embodiment shown in Figure 7 , the fingerprint collection function of the fingerprint collection module is controlled by steps 704-707B, while in the embodiment shown in Figure 5 , the fingerprint collection function of the fingerprint collection module is controlled by steps 504-508, which can be applied to the embodiment shown in Figure 7 to replace the above steps 704-707B, and steps 704-707B can also be applied to the embodiment shown in Figure 5In the illustrated embodiment, steps 504-508 described above are replaced; similarly, steps 504-508 or 704-707B described above can also be applied to other technical solutions based on this disclosure to realize the on / off control of the fingerprint acquisition function of the fingerprint acquisition module.

[0125] Figure 8 A flowchart illustrating another method for indicating the location of fingerprint collection, according to an exemplary embodiment. Figure 8 As shown, the following steps may be included:

[0126] In step 801, the system monitors the triggering of virtual buttons on the payment confirmation page displayed on the mobile phone.

[0127] In this embodiment, with Figure 9 Taking the payment confirmation page shown on the left as an example, the virtual buttons mentioned above can include any virtual button on the payment confirmation page, such as "fingerprint payment," "password payment," or "cancel," and this disclosure does not limit this. The triggering operation for the virtual buttons can include any form such as pressing, touching, clicking, or tapping, and this disclosure does not limit this. Similarly, in addition to the payment confirmation page, this embodiment can also be applied to monitoring the triggering operations of virtual buttons on other preset function pages of the mobile phone. For example, these preset function pages may include login authorization pages, decryption authorization pages, or other pages that can be authorized by the user through fingerprint verification.

[0128] In step 802, it is determined whether the virtual button targeted by the trigger operation is "fingerprint payment".

[0129] In this embodiment, when the virtual button targeted by the triggering operation is not the "fingerprint payment" button on the payment confirmation page, for example, when the user triggers... Figure 9 If the payment confirmation page displays "Password Payment" or "Cancel," the process returns to step 801. If the virtual button triggered by the operation is "Fingerprint Payment" on the payment confirmation page, step 803 is executed. It should be noted that the "Fingerprint Payment" virtual button on the payment confirmation page in step 802 is merely an example. The technical solution of this disclosure is also applicable to triggering operations implemented by combinations of preset virtual buttons, such as "Fingerprint Payment" + "Confirm," "Fingerprint Payment" + "Confirm" + "Agree," etc. These combinations of virtual buttons can be located simultaneously on the payment confirmation page, or they can be located separately in several layers of windows or subpages contained within the payment confirmation page. This disclosure does not limit this. Furthermore, when this embodiment is applied to other preset function pages, different preset virtual buttons can be defined depending on the preset function page. This disclosure does not limit this.

[0130] In step 803, the fingerprint sensing area is shown in the display area of the mobile phone.

[0131] In the embodiment, after determining the fingerprint identification intention of the user, the fingerprint sensing area is shown in the display area of the mobile phone, and is obviously distinguished from other areas in the display area; for example Figure 9 As shown in the right side of the figure, the user can quickly and accurately view the position of the fingerprint sensing area 10 and perform the fingerprint identification operation by showing the fingerprint sensing area 10 in the display area 20, and the fingerprint identification efficiency of the mobile phone is improved.

[0132] It should be noted that: in the embodiment, the fingerprint collection module of the mobile phone can set the fingerprint collection function to a normally closed state, and temporarily open the fingerprint collection function during the showing of the fingerprint sensing area, so as to reduce the power consumption caused by the fingerprint collection module; and in another embodiment, the fingerprint collection module can also set the fingerprint collection function to a normally open state, and the present disclosure does not limit this. For the convenience of description, the technical solutions of the present disclosure are described below by taking the fingerprint collection module in the normally closed state as an example.

[0133] In step 804, when the fingerprint sensing area is in the shown state, it is determined whether the user has performed a pressing operation on the touch display screen of the mobile phone.

[0134] In the embodiment, when the pressing operation performed by the user on the touch display screen of the mobile phone is detected, step 805A is executed; when the operation performed by the user on the touch display screen is not detected, step 805B is executed.

[0135] In step 805A, the operation area of the pressing operation is determined.

[0136] In step 805B, it is determined whether the showing duration of the fingerprint sensing area exceeds a preset duration.

[0137] In the embodiment, step 805B can refer to step 705B in the above Figure 7 , which will not be described here.

[0138] In step 806, it is determined whether the operation area is located in the fingerprint sensing area.

[0139] In this embodiment, step 807 is executed when at least a part of the operation area is located in the fingerprint sensing area; and step 804 is returned to when the operation area is not located in the fingerprint sensing area. In this embodiment, if at least a part of the operation area is located in the fingerprint sensing area, it indicates that the user indeed presses or approaches the finger to the fingerprint sensing area, and the mobile phone can start the fingerprint collection function of the fingerprint collection module at this time; and when the user touch operation is detected, but the operation area of the user touch operation is not located in the fingerprint sensing area, it indicates that the pressing operation in step 803 can be caused by accidental touch, so as to avoid starting the fingerprint collection function and prevent unnecessary power consumption of the fingerprint collection module.

[0140] In step 807, the fingerprint collection function is started, and the input user fingerprint is scanned.

[0141] In this embodiment, step 807 can refer to step 705A in Figure 7 , which will not be repeated here.

[0142] In step 808, it is judged whether the user fingerprint collected during the starting of the fingerprint collection function matches the predefined fingerprint.

[0143] In this embodiment, when the user fingerprint matches the predefined fingerprint, step 809A is executed through user verification; and when the user fingerprint does not match the predefined fingerprint, user verification fails, and step 809B is executed.

[0144] In step 809A, the payment operation of the payment confirmation page is completed.

[0145] In this embodiment, after the user verification succeeds, the mobile phone completes the payment operation of the payment confirmation page. Of course, when this embodiment is applied to other scenarios, corresponding subsequent operations can also be completed; for example, when the above-mentioned preset function page is a login authorization page, the corresponding user login operation can be realized after the user identity is verified according to the collected user fingerprint; for another example, when the above-mentioned preset function page is a decryption authorization page, the corresponding system (or folder, file, or other decryption level) decryption operation can be realized after the user identity is verified according to the collected user fingerprint, which will not be listed one by one here.

[0146] In step 809B, it is judged whether the display duration of the fingerprint sensing area is located in the preset time window.

[0147] In this embodiment, step 809B can refer to step 707B in Figure 7 , which will not be repeated here.

[0148] It should be noted that: Figure 8In the shown embodiment, the fingerprint collection function of the fingerprint collection module is switched on and off by steps 804-809B, which can also be applied to the above-mentioned Figure 5 or Figure 7 In the shown embodiment, the fingerprint collection function of the fingerprint collection module is switched on and off by replacing the corresponding steps 504-508 or steps 704-707B; similarly, the above-mentioned steps 504-508 or steps 704-707B can also be applied to the above-mentioned Figure 8 In the shown embodiment, the fingerprint collection function of the fingerprint collection module is switched on and off by replacing the corresponding steps 804-809B.
