The data maintains a data structure that is a physical location of the memory that has particular characteristics defined by the data format. However, while the principles of the invention have been described in language specific to above, it is not intended to be limited to the specific form set forth herein, but on the contrary, it is to be understood that various steps and operations described hereinafter may be implemented in hardware.
The principles of the present invention are operational with numerous other general purpose or special purpose computing, communication environments or configurations. Examples of well known computing systems, environments, and configurations that may be suitable for use with the invention include, but are not limited to, hand-held telephones, personal computers, servers, multiprocessor systems, microcomputer-based systems, mainframe-based computers, and distributed computing environments that include any of the above systems or devices.
The details will be described below separately.
In the present embodiment, the control device for fingerprint unlocking will be described in terms of the control device for fingerprint unlocking, which may be integrated in a terminal such as a mobile phone, a tablet computer, a Personal Digital Assistant (PDA), and the like.
Referring to fig. 1, fig. 1 is a schematic flowchart of a fingerprint unlocking control method according to an embodiment of the present invention. The method comprises the following steps:
in step S101, the screen state of the terminal is acquired in a state where the terminal opens the fingerprint unlocking module.
In the embodiment of the invention, the fingerprint unlocking module mainly comprises a fingerprint sensing device and a fingerprint information processing chip, wherein the fingerprint sensing device is used for receiving an indication touch operation input by a user, and the fingerprint information processing chip is used for verifying the legality of the touch operation.
For example, firstly, the terminal starts a fingerprint unlocking function, namely, the fingerprint unlocking module is in a starting state, and then the screen state of the terminal is obtained; in this embodiment, the screen state may specifically include a state in which a screen-turning operation is performed, a state in which a screen-lighting operation is performed, a state in which an unlocking operation is performed, and the like.
The screen turning-off operation refers to the operation of triggering the screen of the terminal from bright screen to black screen, and after the screen turning-off operation, the terminal enters a black screen state; the screen-lighting operation refers to an operation of triggering the terminal screen from a black screen to a bright screen, and the unlocking operation refers to an operation of unlocking the terminal screen.
In step S102, it is determined whether the terminal needs to enter a preset power saving mode indicating that the terminal enables a proximity sensor provided on the terminal in a black screen state, based on the screen state.
In step S103, when it is determined that the terminal needs to enter the preset power saving mode and the current screen state is a black screen state, a proximity sensor provided on the terminal is activated and monitored.
For example, the terminal judges whether to start a proximity sensor arranged on the terminal in a black screen state according to the acquired screen state, that is, whether to allow the proximity sensor to perform power saving protection in the black screen state; when the current screen state is allowed to enter the black screen state, the proximity sensor arranged on the terminal can be started, namely, the preset power saving mode is entered.
In the embodiment of the present invention, the proximity sensor may also be referred to as a distance sensor, and mainly determines whether the terminal is covered or blocked by detecting the distance value, and the proximity sensor may specifically be an infrared sensor, an ultrasonic sensor, or a magnetic induction sensor, and the like, which is not limited herein.
It can be understood that when the proximity sensor is controlled to be activated or deactivated, the precondition is that the terminal starts corresponding functions, such as fingerprint unlocking, and the proximity sensor is allowed to perform power saving protection in a black screen state. In the embodiment of the invention, the proximity sensor can be started successfully only in the screen blank state.
In the embodiment of the present invention, there are many embodiments of the terminal "determining whether the terminal needs to enter the preset power saving mode based on the screen state", and in some embodiments, the embodiments may include:
(11) and when the screen state of the terminal is screen turning operation, acquiring the total current amount generated by the fingerprint unlocking module.
(12) And if the total current reaches a preset current threshold, determining that the terminal needs to enter a preset power saving mode.
For example, when the screen state of the terminal is screen turn-off operation, the accumulated total current generated by the fingerprint unlocking module is acquired, and if the total current reaches a preset current threshold, it is determined that the terminal needs to enter a preset power saving mode, that is, the proximity sensor is allowed to be started and power saving protection is performed in a black screen state; after screen turning-off operation, the terminal starts the proximity sensor and monitors after entering a black screen state.
The total current accumulated by the terminal is related to the verification result of the fingerprint unlocking module, and if the terminal is placed in a pocket under the condition of a black screen, false touch is easily triggered, so that the fingerprint unlocking module fails when the verification failure times reach a certain number, and the black screen power consumption is high; therefore, if the received touch operation verification is judged to be failed, if the current image is not the fingerprint, the current amount of current generated by the fingerprint unlocking module is calculated, and the total amount of current generated by the fingerprint unlocking module is updated.
For another example, in some embodiments, the determining, by the terminal, "whether the terminal needs to enter the preset power saving mode based on the screen status" may include:
when the screen state of the terminal is a black screen state, if it is detected that the fingerprint unlocking area receives a touch operation, it is determined that the terminal needs to enter a preset power saving mode.
Based on this, in some embodiments, after the terminal "enables the proximity sensor provided on the terminal and monitors", the method may further include: and if the touch operation verification fails, the control terminal exits the preset power saving mode and stops the proximity sensor.
That is, when the screen is turned off, if the total current accumulated by the terminal reaches a preset current threshold, the proximity sensor is started to monitor, otherwise, the proximity sensor is not started; when the current screen is in a black screen state, if a user touches a fingerprint area, the proximity sensor is started to monitor, after the proximity sensor is started, when the fingerprint is determined to be unsuccessfully checked, the terminal triggers a process of executing screen-off operation, and the proximity sensor is stopped to monitor immediately.
In some embodiments, the terminal may further include, after "enabling and monitoring a proximity sensor provided on the terminal:
and when the screen state of the terminal is detected to be the screen lightening operation or the unlocking operation, the terminal is controlled to exit the preset power saving mode, and the proximity sensor is stopped.
Namely, the screen lightening operation or the unlocking operation can trigger the screen lightening operation in the black screen state, and if the screen lightening operation occurs, the proximity sensor monitoring is stopped immediately no matter what the previous state is.
In step S104, the usage state of the fingerprint unlock module is controlled according to the monitoring result of the proximity sensor.
In the embodiment of the present invention, there are many embodiments of the terminal "controlling the use state of the fingerprint unlocking module according to the monitoring result of the proximity sensor", for example, the embodiments may include:
(21) if the distance value obtained by monitoring of the proximity sensor meets a preset threshold value, the total current generated by the fingerprint unlocking module is obtained, and whether the total current reaches the preset current threshold value is judged.
(22) And if the total current quantity does not reach the preset current threshold value, controlling the fingerprint unlocking module to be in an enabling state.
(23) And if the total current reaches a preset current threshold, controlling the fingerprint unlocking module to be in a stop state.
It can be understood that, on the premise that the proximity sensor is enabled to monitor, it is first determined whether a distance value monitored by the proximity sensor satisfies a preset threshold, that is, whether the terminal is covered or blocked.
If the distance value obtained by monitoring of the proximity sensor meets a preset threshold value, the proximity sensor is covered, whether the total current amount generated by the current fingerprint unlocking module reaches the preset current threshold value or not is further judged, if not, the fingerprint unlocking module is not stopped, and the fingerprint unlocking module is controlled to be in a starting state; if the fingerprint unlocking module is stopped, the fingerprint unlocking module is controlled to be in a stopping state.
Further, after the terminal "controls the fingerprint unlocking module to be in the deactivated state", the fingerprint unlocking module may also be restarted, for example:
and when the distance value obtained by monitoring of the proximity sensor does not meet a preset threshold value or the screen state of the terminal is detected to be the screen lightening operation, the fingerprint unlocking module is restarted.
In some embodiments, when the distance value monitored by the proximity sensor satisfies the preset threshold, the method may further include:
if the fingerprint unlocking area is detected to receive the touch operation verification failure, the current amount generated by the fingerprint unlocking module is calculated, and the total amount of the current generated by the fingerprint unlocking module is updated.
In addition, in some embodiments, after the terminal "enables and monitors the proximity sensor provided on the terminal", the method may further include: and clearing the total current generated by the fingerprint unlocking module according to a preset time interval.
For example, on the premise that the proximity sensor is enabled to monitor, the fingerprint unlocking module detects that the current touch operation verification fails, if the image acquired by touch is not a fingerprint or the fingerprint is incorrect, the current amount is accumulated to obtain the total current amount, and the total current amount is used for judging whether the current amount reaches a set current threshold value; and setting the current total amount to be cleared once according to a preset time interval.
The terms "first", "second", and "third", etc. in the present invention are used for distinguishing different objects, not for describing a particular order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions.
As can be seen from the above, in the control method for fingerprint unlocking provided in this embodiment, when the terminal starts the fingerprint unlocking module, based on the screen state of the terminal, it is determined whether the terminal needs to enter the preset power saving mode, that is, whether the proximity sensor arranged on the terminal needs to be activated in the black screen state, if so, the proximity sensor is activated and monitored in the black screen state, and the use state of the fingerprint unlocking module is controlled according to the monitoring result of the proximity sensor; that is to say, the proximity sensor is added for judging in the black screen state, so that unnecessary power consumption caused by mistaken touch can be avoided under the black screen, power-saving protection of the terminal is realized, and the cruising effect is improved.
The method described in the above embodiments is further illustrated in detail by way of example.
Because the terminal (such as a mobile phone) is in a black screen state, if the anti-false touch processing is not performed, the fingerprint unlocking module is always in a starting state, the power consumption of the terminal is easily larger, and the power saving protection of the fingerprint under the black screen is not well realized. Based on this, in the embodiment of the invention, the proximity sensor installed on the mobile phone is introduced for monitoring, and the use state of the fingerprint unlocking module is controlled according to the monitoring result, so that the power-saving protection of the fingerprint under the black screen is realized.
Referring to fig. 2a, fig. 2a is another schematic flow chart of a fingerprint unlocking control method according to an embodiment of the present invention. The method can comprise the following steps:
in step S201, the terminal starts fingerprint unlocking and allows the proximity sensor to perform power saving protection in a black screen state.
In step S202, the screen status of the terminal is acquired.
In step S203, it is determined whether the terminal enables a proximity sensor provided on the terminal in a black screen state based on the screen state.
In this embodiment, the screen state may specifically include a state in which a screen-turning operation is performed, a state in which a screen-lighting operation is performed, a state in which an unlocking operation is performed, and the like.
The screen turning-off operation refers to the operation of triggering the screen of the terminal from bright screen to black screen, and after the screen turning-off operation, the terminal enters a black screen state; the screen-lighting operation refers to an operation of triggering the terminal screen from a black screen to a bright screen, and the unlocking operation refers to an operation of unlocking the terminal screen.
It can be understood that when the proximity sensor is controlled to be activated or deactivated, the precondition is that the terminal turns on the unlocking of the turn-on fingerprint and allows the proximity sensor to perform power saving protection in the black screen state. In the embodiment of the invention, the proximity sensor can be started successfully only in the screen blank state.
Reference may be made to table 1, which is an exemplary table of proximity sensor activation or deactivation.
TABLE 1
Namely, the proximity sensor is controlled to be activated or deactivated by judging preset parameters in the screen states of different terminals. In the embodiment, two parameters of the fingerprint mode and the total current generated by the fingerprint unlocking module are introduced, and the parameters are combined with the screen state to determine whether the terminal enables the proximity sensor in the black screen state.
In table 1, "0-touch" in the fingerprint mode refers to a state where only a touch operation is received but no verification is performed, and may mainly include a state where the number of times of error in inputting a fingerprint or inputting a password exceeds a certain number (e.g., 5 times), or a state where the sim card is locked by the user id card, "1-auth" refers to a state where a touch operation of unlocking a fingerprint is verified, and "X" is not determined.
In the current threshold value, 0-reaching means that the total current amount generated by the fingerprint unlocking module does not reach a preset current threshold value, 1-reaching means that the total current amount generated by the fingerprint unlocking module reaches the preset current threshold value, and X is not judged.
The accumulated total current is related to a verification result of the fingerprint unlocking module, and if the terminal is placed in a pocket under the condition of a black screen, false touch is easily triggered, so that the fingerprint unlocking module is invalid when the verification failure times reach a certain number, and the black screen power consumption is high; therefore, if the received touch operation verification is judged to be failed, if the current image is not the fingerprint, the current amount of current generated by the fingerprint unlocking module is accumulated.
In one embodiment, in the case that the screen state of the terminal is to perform the screen turning operation:
1-1, if the fingerprint mode is "0", then the proximity sensor is enabled.
1-2, if the fingerprint mode is '1' and the current threshold is '0', the proximity sensor is deactivated.
1-3, if the fingerprint mode is '1' and the current threshold is '1', enabling the proximity sensor.
In another embodiment, after the screen-off operation is performed, the terminal enters a black screen state:
2-1, if the fingerprint mode is '0', the current using state of the proximity sensor is kept and the operation is not carried out.
2-2, if the fingerprint mode is "1", the proximity sensor is enabled when a touch operation is received.
But upon determining that the touch operation failed to verify, the trigger path 2 of the breath screen flow is executed and the proximity sensor is deactivated.
That is, when the screen is turned off, if the total current accumulated by the terminal reaches a preset current threshold, the proximity sensor is started to monitor, otherwise, the proximity sensor is not started; when the current screen is in a black screen state, if a user touches a fingerprint area, the proximity sensor is started to monitor, after the proximity sensor is started, when the fingerprint is determined to be unsuccessfully checked, the terminal triggers a process of executing screen-off operation, and the proximity sensor is stopped to monitor immediately.
It is understood that the proximity sensor is deactivated in case that the screen state of the terminal is a bright screen operation or an unlock operation, i.e., if the bright screen occurs, the proximity sensor is immediately deactivated to listen regardless of the previous state.
In step S204, when it is determined that the proximity sensor needs to be activated and the current screen state is the black screen state, the proximity sensor is activated and monitored.
In step S205, the fingerprint unlocking module is controlled to be deactivated or activated according to the monitoring result of the proximity sensor.
A simple analysis of the control strategy controlling the deactivation or activation of the fingerprint unlock module is as follows:
firstly, because the fingerprint processing in the current black screen state is not different from the bright screen state, unlocking is performed if the verification is successful, counting is performed if the verification is failed, but if false touch occurs in the black screen state (such as false touch triggered by a pocket), failure counting is easily caused to reach a certain number of times (such as 5 times) and fail, and the black screen power consumption is high, a strategy (strategy 1) of proximity sensor monitoring is added in the embodiment of the invention, monitoring is performed in the black screen state, the fingerprint unlocking module is stopped if the proximity sensor is covered, and then the fingerprint module is restarted when the proximity sensor is far away from or the bright screen is opened.
But cannot be unlocked because the proximity sensor is covered, the strategy of proximity sensor listening is further optimized (strategy 2): and monitoring in a black screen state, if the proximity sensor is covered with the fingerprint unlocking module, unlocking and screen lighting can be realized if the fingerprint verification is successful, and counting can not be realized if the fingerprint verification fails.
Furthermore, the two strategies are considered together, and the current threshold is introduced for compatibility: monitoring in a black screen state, if the total current amount does not reach the current threshold when the proximity sensor is covered, not stopping using the fingerprint unlocking module, unlocking and lighting the screen when the fingerprint verification is successful, and counting and not lighting the screen when the fingerprint verification fails; if the total current amount reaches the current threshold when the proximity sensor is covered, the fingerprint unlocking module is deactivated, please refer to fig. 2B, if the total current amount reaches the current threshold when the proximity sensor is covered, when the object moves from the position a to the position B, the object can be considered to be close to the proximity sensor currently, and when the distance reaches the preset threshold, namely the proximity sensor is covered, the fingerprint unlocking module is controlled to be deactivated.
Then, when the object moves from the position B to the position a, the object may be considered to be away from the proximity sensor, and the distance between the object and the proximity sensor does not reach the preset threshold, and then the fingerprint unlocking module is controlled to be restarted.
Table 2 may be referred to together, which shows the specific performance of the product after the proximity sensor is turned on to save power in the black screen state.
TABLE 2
In the fingerprint identification, 0-fail means that the fingerprint verification fails, 1-success means that the fingerprint verification succeeds, and X is not judged.
It can be understood that, on the premise that the proximity sensor is enabled to monitor, the fingerprint unlocking module detects that fingerprint verification fails, if the image acquired by touch is not a fingerprint or the fingerprint is incorrect, the amount of current is accumulated to obtain the total amount of current, and the total amount of current is used for judging whether a set current threshold value is reached; and setting to zero the total current at preset time intervals, for example, every 24 hours, and so on.
The following self-test description of proximity sensor function: for example, setting default allows the proximity sensor to perform power saving protection under black screen, and setting the current threshold to be 50mAH, and these two values can be adjusted according to the policy, such as by a memory update (romuppdate) function.
As can be seen from the above, in the control method for fingerprint unlocking provided in this embodiment, when the terminal starts the fingerprint unlocking module, based on the screen state of the terminal, it is determined whether the terminal needs to enter the preset power saving mode, that is, whether the proximity sensor arranged on the terminal needs to be activated in the black screen state, if so, the proximity sensor is activated and monitored in the black screen state, and the use state of the fingerprint unlocking module is controlled according to the monitoring result of the proximity sensor; that is to say, the proximity sensor is added for judging in the black screen state, so that unnecessary power consumption caused by mistaken touch can be avoided under the black screen, power-saving protection of the terminal is realized, and the cruising effect is improved. In addition, the proximity sensor can be started or stopped according to different conditions, so that the sensor can be prevented from causing excessive power consumption; in a black screen state, the fingerprint module is started or stopped according to a monitoring result of the proximity sensor, and power consumption and experience are both considered; and the power saving protection strategy can be dynamically adjusted by the server according to the actual situation.
In order to better implement the control method for fingerprint unlocking provided by the embodiment of the invention, the embodiment of the invention also provides a device and computer equipment based on the control method for fingerprint unlocking. The meaning of the noun is the same as that in the above method for controlling fingerprint unlocking, and the details of the implementation can refer to the description in the method embodiment.
Referring to fig. 3, fig. 3 is a schematic structural diagram of a fingerprint unlocking control device according to an embodiment of the present invention, where the fingerprint unlocking control device 300 includes an obtaining module 301, a determining module 302, a monitoring module 303, and a control module 304.
The obtaining module 301 is configured to obtain a screen state of the terminal in a state that the terminal starts the fingerprint unlocking module.
In the embodiment of the invention, the fingerprint unlocking module mainly comprises a fingerprint sensing device and a fingerprint information processing chip, wherein the fingerprint sensing device is used for receiving an indication touch operation input by a user, and the fingerprint information processing chip is used for verifying the legality of the touch operation.
For example, firstly, the terminal starts a fingerprint unlocking function, namely, the fingerprint unlocking module is in a starting state, and then the screen state of the terminal is obtained; in this embodiment, the screen state may specifically include a state in which a screen-turning operation is performed, a state in which a screen-lighting operation is performed, a state in which an unlocking operation is performed, and the like.
The screen turning-off operation refers to the operation of triggering the screen of the terminal from bright screen to black screen, and after the screen turning-off operation, the terminal enters a black screen state; the screen-lighting operation refers to an operation of triggering the terminal screen from a black screen to a bright screen, and the unlocking operation refers to an operation of unlocking the terminal screen.
A determining module 302, configured to determine whether the terminal needs to enter a preset power saving mode based on the screen state, where the preset power saving mode indicates that the terminal activates a proximity sensor disposed on the terminal in a black screen state.
The monitoring module 303 is configured to enable a proximity sensor disposed on the terminal and monitor when it is determined that the terminal needs to enter the preset power saving mode and the current screen state is a black screen state. And the control module 304 is configured to control a use state of the fingerprint unlocking module according to a monitoring result of the proximity sensor.
For example, the terminal judges whether to start a proximity sensor arranged on the terminal in a black screen state according to the acquired screen state, that is, whether to allow the proximity sensor to perform power saving protection in the black screen state; when the current screen state is allowed to enter the black screen state, the proximity sensor arranged on the terminal can be started, namely, the preset power saving mode is entered.
In the embodiment of the present invention, the proximity sensor mainly detects the distance value to determine whether the terminal is covered or shielded, and the proximity sensor may be specifically an infrared sensor, an ultrasonic sensor, or a magnetic induction sensor, which is not specifically limited herein.
It can be understood that when the proximity sensor is controlled to be activated or deactivated, the precondition is that the terminal starts corresponding functions, such as fingerprint unlocking, and the proximity sensor is allowed to perform power saving protection in a black screen state. In the embodiment of the invention, the proximity sensor can be started successfully only in the screen blank state.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a fingerprint unlocking control device 400 according to an embodiment of the present invention.
In this embodiment of the present invention, there are many embodiments in which the determining module 302 in the control apparatus 400 for fingerprint unlocking determines whether the terminal needs to enter the preset power saving mode based on the screen state, and in some embodiments, the determining module may include:
the first obtaining submodule 3021 is configured to obtain the total amount of current generated by the fingerprint unlocking module when the screen state of the terminal is the screen turn-off operation.
The first determining submodule 3022 is configured to determine that the terminal needs to enter a preset power saving mode if the total current amount reaches a preset current threshold.
For example, when the screen state of the terminal is screen turn-off operation, the accumulated total current generated by the fingerprint unlocking module is acquired, and if the total current reaches a preset current threshold, it is determined that the terminal needs to enter a preset power saving mode, that is, the proximity sensor is allowed to be started and power saving protection is performed in a black screen state; after screen turning-off operation, the terminal starts the proximity sensor and monitors after entering a black screen state.
The total current accumulated by the terminal is related to the verification result of the fingerprint unlocking module, and if the terminal is placed in a pocket under the condition of a black screen, false touch is easily triggered, so that the fingerprint unlocking module fails when the verification failure times reach a certain number, and the black screen power consumption is high; therefore, if the received touch operation verification is judged to be failed, if the current image is not the fingerprint, the current amount of current generated by the fingerprint unlocking module is calculated, and the total amount of current generated by the fingerprint unlocking module is updated.
For another example, in some embodiments, as shown in fig. 4, the determining module 302 may further include:
the second determining submodule 3023 is configured to, when the screen state of the terminal is a black screen state, determine that the terminal needs to enter a preset power saving mode if it is detected that the fingerprint unlocking area receives a touch operation.
Based on this, in some embodiments, the control device 400 for fingerprint unlocking may further include: a first disabling module 305, configured to, if it is determined that the touch operation verification fails, control the terminal to exit a preset power saving mode, and disable the proximity sensor.
That is, when the screen is turned off, if the total current accumulated by the terminal reaches a preset current threshold, the proximity sensor is started to monitor, otherwise, the proximity sensor is not started; when the current screen is in a black screen state, if a user touches a fingerprint area, the proximity sensor is started to monitor, after the proximity sensor is started, when the fingerprint is determined to be unsuccessfully checked, the terminal triggers a process of executing screen-off operation, and the proximity sensor is stopped to monitor immediately.

In the embodiment of the present invention, there are many embodiments in which the control module 304 in the control apparatus 400 for unlocking a fingerprint controls the usage state of the fingerprint unlocking module according to the monitoring result of the proximity sensor, for example, as shown in fig. 4, the implementation may include:
the second obtaining submodule 3041 is configured to, if the distance value obtained through monitoring by the proximity sensor meets a preset threshold, obtain a total amount of current generated by the fingerprint unlocking module.
The determining submodule 3042 is configured to determine whether the total current amount reaches a preset current threshold.
The first control submodule 3043 is configured to control the fingerprint unlocking module to be in an enabled state if the total current amount does not reach the preset current threshold.
The second control submodule 3044 is configured to control the fingerprint unlocking module to be in a deactivated state if the total current amount reaches a preset current threshold.
It can be understood that, on the premise that the proximity sensor is started to monitor, whether the distance value monitored by the proximity sensor meets a preset threshold value is judged, that is, whether the terminal is covered or shielded is judged; if the distance value obtained by monitoring of the proximity sensor meets a preset threshold value, the proximity sensor is covered, whether the total current amount generated by the current fingerprint unlocking module reaches the preset current threshold value or not is further judged, if not, the fingerprint unlocking module is not stopped, and the fingerprint unlocking module is controlled to be in a starting state; if the fingerprint unlocking module is stopped, the fingerprint unlocking module is controlled to be in a stopping state.
Further, as shown in fig. 4, after controlling the fingerprint unlocking module to be in the deactivated state, the control device 400 for fingerprint unlocking may also restart the fingerprint unlocking module, such as may further include:
and a re-enabling module 307, configured to re-enable the fingerprint unlocking module when the distance value monitored by the proximity sensor does not meet the preset threshold, or the screen state of the terminal is detected as a screen-on operation.

and the current calculating module 308 is configured to calculate a current amount currently generated by the fingerprint unlocking module and update a total amount of current generated by the fingerprint unlocking module if the distance value monitored by the proximity sensor meets a preset threshold and it is detected that the touch operation verification received by the fingerprint unlocking region fails.
And an emptying module 309, configured to empty the total amount of current generated by the fingerprint unlocking module according to a preset time interval.
For example, on the premise that the proximity sensor is enabled to monitor, the fingerprint unlocking module detects that the current touch operation verification fails, if the image acquired by touch is not a fingerprint or the fingerprint is incorrect, the current amount is accumulated to obtain the total current amount, and the total current amount is used for judging whether the current amount reaches a set current threshold value; and setting the current total amount to be cleared once according to a preset time interval.
