If the terminal's current posture information is in a state prone to accidental triggering, the trigger duration can be appropriately extended as needed, thereby reducing the likelihood of screen unlocking due to accidental triggering.

[0054] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0059] Figure 4 This is a block diagram illustrating a terminal device according to an exemplary embodiment. Detailed Implementation

[0060] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0061] With the rapid development of electronic technology, electronic products are evolving towards greater user-friendliness and higher quality. Especially in terms of information security, screen lock functions have emerged to improve the security of electronic products. When the screen is locked, unlocking is required to access and operate the device. However, accidental triggering frequently occurs when the device is in motion.

[0062] This disclosure provides a fingerprint unlocking method. Figure 1 This is a flowchart illustrating a fingerprint unlocking method according to an exemplary embodiment. Figure 1 As shown, fingerprint unlocking methods include:

[0063] Step 10: Obtain the current attitude information of the terminal;

[0064] Step 11: Based on the current posture information of the terminal, determine the trigger duration for the terminal to unlock the screen via fingerprint.

[0065] Step 12: If the fingerprint trigger duration applied to the unlock button on the terminal screen reaches the trigger duration, then unlock the screen.

[0066] In this embodiment of the disclosure, the fingerprint unlocking method can be applied to a terminal with a screen unlock button on the side. For example, a mobile phone with a screen unlock button on the side.

[0067] In this embodiment of the disclosure, the current posture information can be used to characterize the current motion state of the terminal and / or the posture presented by the terminal at the current moment. The presented posture includes at least: a horizontal placement posture, a vertical placement posture, etc.

[0068] In this embodiment of the disclosure, the current posture of the terminal can be determined through the terminal's current posture information. After determining the current posture information of the terminal, the trigger duration for unlocking the screen via fingerprint in the current posture can be determined.

[0069] In this embodiment, when a user touches the screen unlock button and their fingerprint is applied to it, the screen unlocks when the fingerprint trigger duration reaches a trigger duration determined based on the terminal's current posture information. The fingerprint trigger duration is the length of time the fingerprint remains on the screen unlock button. The fingerprint unlocking method in this embodiment includes: acquiring the terminal's current posture information; determining, based on the terminal's current posture information, the trigger duration for unlocking the screen via fingerprint; and unlocking the screen once the fingerprint trigger duration applied to the screen unlock button reaches the required trigger duration. In this application, the terminal can unlock the screen via fingerprint triggering of the screen unlock button. However, when the terminal is in use, accidental triggering frequently occurs. To reduce accidental screen unlocking, this application determines the fingerprint trigger duration for screen unlocking based on the terminal's current posture information. If the terminal's current posture information is in a state prone to accidental triggering, the trigger duration can be appropriately extended as needed, thereby reducing the occurrence of screen unlocking due to accidental triggering.

[0070] In some embodiments, determining the trigger duration for unlocking the screen via fingerprint based on the current posture information of the terminal includes:

[0071] Based on the judgment result of whether the current posture information of the terminal meets the preset conditions, the trigger duration for the terminal to unlock the screen by fingerprint is determined.

[0072] In this embodiment, when determining the trigger duration for unlocking the screen via fingerprint, the system first determines whether the terminal's current posture information meets preset conditions. Then, based on the determination of whether the terminal's current posture information meets the preset conditions, the trigger duration for unlocking the screen via fingerprint is determined. The preset conditions characterize a state where the terminal is prone to false triggering. When the terminal's current posture information meets the preset conditions, it indicates that the terminal is currently in a state prone to false triggering. In this case, the trigger duration for unlocking the screen via fingerprint is longer than the trigger duration when the terminal is in a state less prone to false triggering. By determining the trigger duration for unlocking the screen via fingerprint based on whether the terminal's current posture information meets the preset conditions, flexible adjustment of the trigger duration can be achieved, reducing the likelihood of screen unlocking due to false triggering in a state prone to false triggering.

[0073] In some embodiments, determining the trigger duration for unlocking the screen via fingerprint based on whether the current posture information of the terminal meets preset conditions includes at least one of the following:

[0074] If it is determined that the current posture information of the terminal meets the preset conditions, then the trigger duration for the terminal to unlock the screen via fingerprint is determined to be the first duration.

[0075] If it is determined that the current posture information of the terminal does not meet the preset conditions, then the trigger duration for the terminal to unlock the screen via fingerprint is determined to be the second duration; wherein, the first duration is longer than the second duration.

[0076] In this embodiment, the preset condition is used to characterize a state where the terminal is prone to false triggering. When it is determined that the current posture information of the terminal meets the preset condition, it indicates that the terminal is currently in a state prone to false triggering, and the trigger duration for unlocking the screen via fingerprint is determined to be a first duration; when it is determined that the current posture information of the terminal does not meet the preset condition, it indicates that the terminal is not currently in a state prone to false triggering, and the trigger duration for unlocking the screen via fingerprint is determined to be a second duration; the first duration is longer than the second duration. Thus, when the terminal is currently in a state prone to false triggering, appropriately extending the trigger duration can reduce the possibility of the screen being unlocked due to false triggering in this state.

[0077] In some embodiments, the current attitude information includes at least one of the following:

[0078] The acceleration of the terminal along each coordinate axis in the three-dimensional coordinate system at the current moment;

[0079] The change in angular velocity of the terminal along each coordinate axis in the three-dimensional coordinate system within the current time window;

[0080] The current posture information of the terminal satisfies preset conditions, including at least one of the following:

[0081] The acceleration of the terminal along each coordinate axis in the three-dimensional coordinate system at the current moment satisfies a first preset condition; the first preset condition is used to characterize the terminal's preset first motion state through acceleration;

[0082] The change in angular velocity of the terminal along each coordinate axis in the three-dimensional coordinate system within the current time window satisfies the second preset condition; the second preset condition is used to characterize the second preset motion state of the terminal through angular velocity.

[0083] In this embodiment, the terminal's acceleration can be acquired by an accelerometer integrated within the terminal. The change in angular velocity can be acquired by a gyroscope integrated within the terminal. The time window can be set as needed. The terminal's current attitude information satisfies at least one of the following preset conditions: acceleration satisfies a first preset condition, and the change in angular velocity satisfies a second preset condition.

[0084] In this embodiment, both the first and second operating states refer to states where the terminal is prone to accidental fingerprint unlocking. The first operating state indicates that the terminal's motion fluctuates significantly, making accidental fingerprint unlocking more likely. The second operating state indicates that the terminal's current posture is in a state prone to accidental fingerprint unlocking.

[0085] In some embodiments, the acceleration of the terminal along each coordinate axis in the three-dimensional coordinate system at the current moment satisfies a first preset condition, including:

[0086] The root mean square of the acceleration of the terminal along the X-axis, Y-axis, and Z-axis at the current moment is greater than a first threshold; and / or, the acceleration of the terminal along the Y-axis at the current moment is less than a third threshold;

[0087] The change in angular velocity of the terminal along each coordinate axis in the three-dimensional coordinate system within the current time window satisfies the second preset condition, including:

[0088] The root mean square of the change in angular velocity of the terminal along the X-axis, Y-axis, and Z-axis within the current time window is greater than the second threshold.

[0089] In this embodiment, the first threshold, second threshold, and third threshold can be set as needed. The Z-axis in the three-dimensional coordinate system is perpendicular to the surface of the terminal screen and pointing upwards. The X-axis in the three-dimensional coordinate system is along the longer side of the terminal screen surface, and the Y-axis is along the shorter side of the terminal screen surface.

[0090] In this embodiment of the disclosure, when the root mean square of the acceleration of the terminal along the X-axis, Y-axis, and Z-axis at the current moment is greater than a first threshold, and / or the root mean square of the change in angular velocity along the X-axis, Y-axis, and Z-axis within the current time window is greater than a second threshold, the terminal is in a state where it is prone to accidental fingerprint unlocking.

[0091] In this embodiment, when the acceleration along the Y-axis of the terminal at the current moment is less than a third threshold, the terminal is considered to be facing downwards, almost vertically downwards. At this time, the terminal is likely to be in a state where accidental fingerprint unlocking is possible. When the acceleration along the Y-axis is close to -9.8 m / s², the terminal is almost vertically downwards. The third threshold can be set to a value close to -9.8 m / s².

[0092] In some embodiments, the method further includes:

[0093] Get the current screen display status of the terminal;

[0094] When the screen of the terminal is in a screen-off state, the number of times the unlock button of the terminal screen is pressed within a preset time period is detected.

[0095] When the number of presses reaches a preset number, the trigger duration for the terminal to unlock the screen via fingerprint is determined to be a third duration; wherein the third duration is longer than the second duration.

[0096] In this embodiment, when the terminal screen is in a screen-off state, if the number of presses on the terminal screen unlock button within a preset time period reaches a preset number, it indicates that the number of presses on the screen unlock button within the preset time period is relatively frequent. At this time, the user may not want to unlock the device but only want to check the time. Therefore, the triggering time can be appropriately extended, i.e., the triggering time for the terminal to unlock the screen via fingerprint is determined to be the third time period. The second time period is the triggering time for the terminal to unlock the screen via fingerprint under normal circumstances. In this application, when the terminal is in a screen-off state, the screen can also be unlocked directly via fingerprint.

[0097] In this application, the screen unlocking process of the terminal can be divided into: screen unlocking during the screen-off phase and screen unlocking during the screen-on phase.

[0098] When the screen is unlocked during the screen-off phase, the fingerprint sensor in the terminal's screen unlock button recognizes the fingerprint acting on the unlock button and continues to act for a duration of a third time period. At this time, the terminal screen is turned on and unlocked. The third time period is a predetermined time threshold.

[0099] When determining the duration of the third time period, it can be based on the number of times the user presses the screen unlock button within a preset time period recorded by the terminal. For example, the terminal records the number of times the user quickly presses the screen unlock button again within a preset time period (which can be a few seconds) after pressing the screen unlock button (or the power button with screen unlock function). The time can be dynamically adjusted based on this number of presses. If the number of presses is too high, exceeding the preset number, it indicates that the user prefers to keep the screen on rather than unlock it. In this case, the duration of the third time period can be dynamically increased.

[0100] When unlocking the screen during the screen-on phase, the device's current posture or motion state is determined using an accelerometer and gyroscope integrated within the terminal. Based on the current posture and / or motion state, the trigger duration for unlocking the screen via fingerprint is determined.

[0101] For example, by recognizing the user's movement behavior, a targeted anti-mistouch strategy is implemented when the user is holding the terminal and the top of the terminal is facing down. If this scenario is recognized, the unlocking operation will not be performed.

[0102] Specific plan:

[0103] S01, Set a time window and read acceleration data and gyroscope data; the time window is not fixed, as long as enough status data can be obtained, to avoid excessive data collection due to an excessively long time window, which would increase the terminal's computing power consumption.

[0104] S02, Calculate the fluctuation characteristics of the state data: calculate the root mean square (RMS) of the acceleration and gyroscope three-axis data increments.

[0105] S03, when RMS > preset value A, it can be understood that the terminal fluctuates greatly at this time.

[0106] S04, when the terminal's acceleration along the Y-axis at the current moment is less than the preset value B, it can be considered that the top of the terminal is facing down and the terminal is almost vertically downward. This indicates that the terminal is very likely to accidentally trigger the screen unlock.

[0107] S05, A and B are empirical values ​​(B<0), where B is a value close to -9.8m / s^2. When B is smaller, the terminal is closer to vertical downwards, which means that the terminal is more likely to accidentally trigger screen unlock. When B is larger, the phone is closer to horizontal, which means that the probability of the terminal accidentally triggering screen unlock is smaller.

[0108] S06. When both conditions are met, it can be considered that the expected scenario is in progress. The fingerprint sensor's recognition of the fingerprint trigger is more likely to be a false trigger. At this time, the unlocking function is disabled.

[0109] Therefore, to prevent accidental screen unlocking and to avoid users being unable to unlock, a time threshold C can be set as the duration of the trigger. The fingerprint sensor detects that the time applied to the screen unlock button exceeds this time threshold C, unlocking the terminal screen. Compared to the third duration, this time threshold C can be set to be longer.

[0110] Figure 2 This is a schematic diagram illustrating an application of a fingerprint unlocking method according to an exemplary embodiment. For example... Figure 2 As shown, a screen unlock button may be located on the side of the terminal. The terminal's screen can be unlocked by triggering a fingerprint.

[0111] This disclosure also provides a fingerprint unlocking device for use on the screen unlock button on the side of a terminal. Figure 3 This is a schematic diagram illustrating the structure of a fingerprint unlocking device according to an exemplary embodiment. Figure 3 As shown, the device includes:

[0112] The first processing unit 31 is used to obtain the current attitude information of the terminal;

[0113] The second processing unit 32 is used to determine the trigger duration for the terminal to unlock the screen via fingerprint based on the terminal's current posture information.

[0114] The third processing unit 33 is used to determine if the fingerprint trigger duration applied to the terminal screen unlock button reaches the trigger duration, and then unlock the screen.

[0115] In this embodiment of the disclosure, the fingerprint unlocking device can be applied to a terminal with a screen unlock button on the side. For example, a mobile phone with a screen unlock button on the side.

[0116] In this embodiment of the disclosure, the current posture information can be used to characterize the current motion state of the terminal and / or the posture presented by the terminal at the current moment. The presented posture includes at least: a horizontal placement posture, a vertical placement posture, etc.

[0117] In this embodiment of the disclosure, the current posture of the terminal can be determined through the terminal's current posture information. After determining the current posture information of the terminal, the trigger duration for unlocking the screen via fingerprint in the current posture can be determined.

[0118] In this embodiment, when a user touches the screen unlock button and their fingerprint is applied to it, the screen unlocks when the fingerprint trigger duration reaches a trigger duration determined based on the terminal's current posture information. The fingerprint trigger duration is the length of time the fingerprint remains on the screen unlock button. The fingerprint unlocking device in this embodiment includes: acquiring the terminal's current posture information; determining, based on the terminal's current posture information, the trigger duration for unlocking the screen via fingerprint; and unlocking the screen once the fingerprint trigger duration applied to the screen unlock button reaches the required trigger duration. In this application, the terminal can unlock the screen via fingerprint triggering of the screen unlock button. However, when the terminal is in use, accidental triggering frequently occurs. To reduce accidental screen unlocking, this application determines the fingerprint trigger duration for screen unlocking based on the terminal's current posture information. If the terminal's current posture information is in a state prone to accidental triggering, the trigger duration can be appropriately extended as needed, thereby reducing the occurrence of screen unlocking due to accidental triggering.

[0119] In some embodiments, the second processing unit is specifically used for

[0120] Based on the judgment result of whether the current posture information of the terminal meets the preset conditions, the trigger duration for the terminal to unlock the screen by fingerprint is determined.

[0121] In this embodiment, the preset condition is used to characterize a state where the terminal is prone to false triggering. When the terminal's current posture information meets the preset condition, it indicates that the terminal is currently in a state prone to false triggering. In this case, the trigger duration for unlocking the screen via fingerprint is determined to be longer than the trigger duration when the terminal is in a state less prone to false triggering. By determining whether the terminal's current posture information meets the preset condition to determine the trigger duration for unlocking the screen via fingerprint, flexible adjustment of the trigger duration can be achieved, reducing the likelihood of screen unlocking due to false triggering in a state prone to false triggering.

[0122] In some embodiments, the second processing unit is specifically used for

[0123] If it is determined that the current posture information of the terminal meets the preset conditions, then the trigger duration for the terminal to unlock the screen via fingerprint is determined to be the first duration.

[0124] If it is determined that the current posture information of the terminal does not meet the preset conditions, then the trigger duration for the terminal to unlock the screen via fingerprint is determined to be the second duration; wherein, the first duration is longer than the second duration.

[0125] In this embodiment, the preset condition is used to characterize a state where the terminal is prone to false triggering. When it is determined that the current posture information of the terminal meets the preset condition, it indicates that the terminal is currently in a state prone to false triggering, and the trigger duration for unlocking the screen via fingerprint is determined to be a first duration; when it is determined that the current posture information of the terminal does not meet the preset condition, it indicates that the terminal is not currently in a state prone to false triggering, and the trigger duration for unlocking the screen via fingerprint is determined to be a second duration; the first duration is longer than the second duration. Thus, when the terminal is currently in a state prone to false triggering, appropriately extending the trigger duration can reduce the possibility of the screen being unlocked due to false triggering in this state.

[0126] In some embodiments, the current attitude information includes at least one of the following:

[0127] The acceleration of the terminal along each coordinate axis in the three-dimensional coordinate system at the current moment;

[0128] The change in angular velocity of the terminal along each coordinate axis in the three-dimensional coordinate system within the current time window;

[0129] The current posture information of the terminal satisfies preset conditions, including at least one of the following:

[0130] The acceleration of the terminal along each coordinate axis in the three-dimensional coordinate system at the current moment satisfies a first preset condition; the first preset condition is used to characterize the terminal's preset first motion state through acceleration;

[0131] The change in angular velocity of the terminal along each coordinate axis in the three-dimensional coordinate system within the current time window satisfies the second preset condition; the second preset condition is used to characterize the second preset motion state of the terminal through angular velocity.

[0132] In this embodiment, the terminal's acceleration can be acquired by an accelerometer integrated within the terminal. The change in angular velocity can be acquired by a gyroscope integrated within the terminal. The time window can be set as needed. The terminal's current attitude information satisfies at least one of the following preset conditions: acceleration satisfies a first preset condition, and the change in angular velocity satisfies a second preset condition.

[0133] In this embodiment, both the first and second operating states refer to states where the terminal is prone to accidental fingerprint unlocking. The first operating state indicates that the terminal's motion fluctuates significantly, making accidental fingerprint unlocking more likely. The second operating state indicates that the terminal's current posture is in a state prone to accidental fingerprint unlocking.

[0134] In some embodiments, the acceleration of the terminal along each coordinate axis in the three-dimensional coordinate system at the current moment satisfies a first preset condition, including:

[0135] The root mean square of the acceleration of the terminal along the X-axis, Y-axis, and Z-axis at the current moment is greater than a first threshold; and / or, the acceleration of the terminal along the Y-axis at the current moment is less than a third threshold;

[0136] The change in angular velocity of the terminal along each coordinate axis in the three-dimensional coordinate system within the current time window satisfies the second preset condition, including:

[0137] The root mean square of the change in angular velocity of the terminal along the X-axis, Y-axis, and Z-axis within the current time window is greater than the second threshold.

[0138] In this embodiment, the first threshold, second threshold, and third threshold can be set as needed. The Z-axis in the three-dimensional coordinate system is perpendicular to the surface of the terminal screen and pointing upwards. The X-axis in the three-dimensional coordinate system is along the longer side of the terminal screen surface, and the Y-axis is along the shorter side of the terminal screen surface.

[0139] In this embodiment of the disclosure, when the root mean square of the acceleration of the terminal along the X-axis, Y-axis, and Z-axis at the current moment is greater than a first threshold, and / or the root mean square of the change in angular velocity along the X-axis, Y-axis, and Z-axis within the current time window is greater than a second threshold, the terminal is in a state where it is prone to accidental fingerprint unlocking.

[0140] In this embodiment, when the acceleration along the Y-axis of the terminal at the current moment is less than a third threshold, the terminal is considered to be facing downwards, almost vertically downwards. At this time, the terminal is likely to be in a state where accidental fingerprint unlocking is possible. When the acceleration along the Y-axis is close to -9.8 m / s², the terminal is almost vertically downwards. The third threshold can be set to a value close to -9.8 m / s².

[0141] In some embodiments, the second processing unit is further configured to...

[0142] Get the current screen display status of the terminal;

[0143] When the screen of the terminal is in a screen-off state, the number of times the unlock button of the terminal screen is pressed within a preset time period is detected.

[0144] When the number of presses reaches a preset number, the trigger duration for the terminal to unlock the screen via fingerprint is determined to be a third duration; wherein the third duration is longer than the second duration.

[0145] In this embodiment of the disclosure, when the terminal's screen is in a screen-off state, if the number of presses on the terminal's screen unlock button within a preset time period reaches a preset number, it indicates that the number of presses on the screen unlock button within the preset time period is relatively frequent. At this time, the user may not want to unlock the device but only wants to check the time. Therefore, the triggering time can be appropriately extended, that is, the triggering time for determining that the terminal can unlock the screen via fingerprint is the third time period. The second time period is the triggering time for the terminal to unlock the screen via fingerprint under normal circumstances.
