Background

The biometric identification technology is characterized in that personal identity is identified by closely combining a computer with high-tech means such as optics, acoustics, biosensors and the principle of biometrics and utilizing inherent physiological characteristics (such as fingerprints, face images, irises and the like) and behavior characteristics (such as handwriting, voice, gait and the like) of a human body.

The biological identification technology has the advantages of difficult forgetting, good anti-counterfeiting performance, difficult counterfeiting or theft, portability, availability at any time and any place and the like. Therefore, biometric identification technology is widely applied to terminals such as mobile phones.

Those skilled in the art will appreciate that the handset configuration shown in fig. 1 is not intended to be limiting and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.

The functional components of the mobile phone 100 are described below:

the RF circuit 110 may be used for receiving and transmitting signals during information transmission and reception or during a call, and in particular, receives downlink information of a base station and then processes the received downlink information to the processor 150; in addition, the uplink data is transmitted to the base station. In general, the RF circuit 110 is not limited to an antenna, at least one amplifier, a transceiver, a coupler, a Low Noise Amplifier (LNA), a duplexer, and the like. In addition, the RF circuitry 110 may also communicate with networks and other devices via wireless communications. The wireless communication may use any communication standard or protocol, including but not limited to global system for mobile communications (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE), email, Short Message Service (SMS), etc.

The memory 120 may be used to store software programs and modules, and the processor 150 executes various functional applications and data processing of the mobile phone 100 by operating the software programs and modules stored in the memory 120. The memory 120 may mainly include a program storage area and a data storage area, wherein the program storage area may store an operating system, an Application (APP) required by at least one function, and the like, such as a sound playing function, an image playing function, and the like; the storage data area may store data (such as audio data, image data, a phonebook, etc.) created according to the use of the cellular phone 100, and the like. Further, the memory 120 may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device.

The input unit 130 may be used to receive numeric or character information input by a user and generate key signal inputs related to user settings and function control of the cellular phone 100. Specifically, the input unit 130 may include a touch screen 131 and other input devices 132. The touch screen 131, also referred to as a touch panel, may collect touch operations of a user (e.g., operations of the user on the touch screen 131 or near the touch screen 131 using any suitable object or accessory such as a finger or a stylus) thereon or nearby, and drive the corresponding connection device according to a preset program. Alternatively, the touch screen 131 may include two parts, a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, sends the touch point coordinates to the processor 150, and can receive and execute commands sent by the processor 150. In addition, the touch screen 131 may be implemented in various types, such as resistive, capacitive, infrared, and surface acoustic wave. The input unit 130 may include other input devices 132 in addition to the touch screen 131. In particular, other input devices 132 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, power switch keys, etc.), a trackball, a mouse, a joystick, and the like.

The biometric sensor 140 specifically includes a fingerprint recognition sensor 141, a face recognition sensor 142, and an iris recognition sensor 143. Taking a fingerprint identification sensor as an example, the fingerprint identification sensor can collect fingerprint information of a user and report the collected fingerprint information to the processor 150, and the processor 150 identifies the user according to the fingerprint information. Based on the biometric sensor 140, the mobile phone can perform authentication on the user according to the fingerprint input by the user on the screen locking interface, and when the authentication is successful, the mobile phone is unlocked. Based on the biometric sensor 140, the cell phone may also authenticate the user at certain payment applications, and when the authentication is successful, the user may use the payment application to make a payment.

The display unit 170 may be used to display information input by or provided to the user and various menus of the mobile phone 100. The Display unit 170 may include a Display panel 171, and optionally, the Display panel 171 may be configured in the form of a Liquid Crystal Display (LCD), an Organic Light-Emitting Diode (OLED), or the like. Further, the touch screen 131 may cover the display panel 171, and when the touch screen 131 detects a touch operation thereon or nearby, the touch screen is transmitted to the processor 150 to determine the type of the touch event, and then the processor 150 provides a corresponding visual output on the display panel 171 according to the type of the touch event. Although in fig. 1 the touch screen 131 and the display panel 171 are shown as two separate components to implement the input and output functions of the cell phone 100, in some embodiments the touch screen 131 and the display panel 171 may be integrated to implement the input and output functions of the cell phone 100.

The gravity sensor 180 may detect the acceleration of the mobile phone in each direction (generally, three axes), detect the magnitude and direction of the gravity when the mobile phone is stationary, and may be used for applications of recognizing the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), and the like.

The handset 100 may also include other sensors, such as light sensors. In particular, the light sensor may include an ambient light sensor and a proximity light sensor. The ambient light sensor can adjust the brightness of the display panel 131 according to the brightness of ambient light; the proximity light sensor may detect whether an object is near or touching the phone, and may turn off the display panel 131 and/or the backlight when the phone 100 is moved to the ear. The mobile phone 100 may also be configured with other sensors such as a gyroscope, a barometer, a hygrometer, a thermometer, and an infrared sensor, which will not be described herein.

The audio circuitry 190, speaker 191, and microphone 192 can provide an audio interface between a user and the handset 100. The audio circuit 190 may transmit the electrical signal converted from the received audio data to the speaker 191, and the electrical signal is converted into a sound signal by the speaker 191 and output; on the other hand, the microphone 192 converts the collected sound signals into electrical signals, which are received by the audio circuit 190 and converted into audio data, which are then output to the RF circuit 110 for transmission to, for example, another cell phone, or to the memory 120 for further processing.

The processor 150 is a control center of the mobile phone 100, connects various parts of the entire mobile phone by using various interfaces and lines, and performs various functions of the mobile phone 100 and processes data by operating or executing software programs and/or modules stored in the memory 120 and calling data stored in the memory 120, thereby performing overall monitoring of the mobile phone. Alternatively, processor 150 may include one or more processing units; alternatively, the processor 150 may integrate an application processor, which primarily handles operating systems, user interfaces, application programs, etc., and a modem processor, which primarily handles wireless communications. It will be appreciated that the modem processor described above may not be integrated into the processor 150.

The handset 100 also includes a power supply 160 (e.g., a battery) for powering the various components, optionally logically connected to the processor 150 via a power management system, so as to manage charging, discharging, and power consumption via the power management system.

Although not shown, the handset 100 may also include an antenna, a Wireless-Fidelity (WiFi) module, a Near Field Communication (NFC) module, a bluetooth module, a speaker, an accelerometer, a gyroscope, and the like.

Currently, due to the convenience of biometric identification, more and more terminals support biometric identification. Taking the biometric identification as the fingerprint identification as an example, more and more terminals support fingerprint unlocking, and payment applications such as payment treasured, WeChat and the like installed on the terminals also support identity verification through fingerprints, and after the fingerprint verification is successful, a user can pay. The terminal with the biological feature recognition function is a double-edged sword. On one hand, when the user uses the terminal with the biological characteristic identification function, the quick identity authentication can be realized, and the quick terminal unlocking or quick payment of the user can be facilitated. On the other hand, in the following scenarios, the privacy information of the user and the like are also easily leaked due to the convenience of the biometric function.

Application scenarios: the mobile phone is stolen when a user sleeps, and a thief can operate the finger of the user to unlock the mobile phone by using the fingerprint of the user to obtain the permission to use the mobile phone when the user does not wake up, so that the account information of the payment application installed in the mobile phone, the photos in the photo album, the contact person and other privacy information can be checked. Even, the thief can use the fingerprint of the user to perform fingerprint verification in the payment application, and perform illegal operations such as transfer after the fingerprint verification is successful.

In order to solve the problem that privacy information of a user is easily leaked due to the convenience of biometric identification and even lost in an emergency, an embodiment of the present application provides a function control method, which is applicable to a terminal shown in fig. 1, as shown in fig. 2, and includes the following steps:

201. the terminal receives a first operation input by a user.

The first operation comprises fingerprint, iris and other biological identification characteristic information input by a user, and also comprises the step that the user presses a specific physical key, specifically comprises clicking, double clicking and pressing the specific physical key according to a certain rule, such as pressing a volume increasing key and a volume decreasing key at the same time. The first operation also comprises the user inputting a specific voice instruction, such as a voice instruction containing a specific word such as 'lock'. The first operation further comprises a user inputting a preset gesture. The first operation also includes the user entering a particular password, such as: the user inputs a first specific password for unlocking the terminal, and the user inputs a second specific password for triggering the terminal to disable the preset function. The first operation further comprises the user moving the mobile phone in a specific direction and the like. The first operation may also be other shortcut operations, and the embodiment of the present application does not limit a specific implementation of the first operation.

It should be noted that the first operation is a shortcut operation for triggering the terminal to disable the preset function. Through this swift operation, can realize forbidding the biological characteristic recognition function fast. The user does not need to disable the preset functions such as the biological characteristic recognition function after setting in the setting function option of the terminal, and the like, and the problem of complex operation is caused.

202. And the terminal forbids a preset function according to the first operation.

The forbidden preset function comprises a biological characteristic identification function, and the biological characteristic identification function specifically comprises iris identification, fingerprint identification, face identification and the like. Taking the biometric function as a fingerprint identification function as an example, the way of disabling the fingerprint identification function includes: the first mode is that the terminal is provided with a fingerprint identification sensor to prohibit the fingerprint sensor from working. For example: the terminal closes the fingerprint sensor, or the supply current of the terminal to the fingerprint identification sensor is small, so that the fingerprint identification sensor is in a standby state. In this manner, even if the user inputs a fingerprint, the fingerprint recognition sensor cannot operate, and the fingerprint of the user cannot be collected. And secondly, the terminal modifies the system configuration file so that the system configuration file contains indication information that the fingerprint identification function is forbidden. After the fingerprint identification function is disabled, the fingerprint identification function is disabled. The concrete implementation is as follows: the fingerprint sensor collects fingerprints input by a user and reports the fingerprints to the processor, after the processor receives the fingerprints collected by the fingerprint sensor, the processor checks a system configuration file, determines that the current fingerprint identification function of the terminal is forbidden, and does not process the fingerprints collected by the fingerprint sensor or defaults to return an indication of authentication failure to an upper-layer application. For example: the user installs a payment application of 'electronic wallet' on the terminal, after the fingerprint identification function is forbidden, the user inputs a fingerprint on an electronic wallet interface, the processor receives the fingerprint acquired by the fingerprint sensor, checks a system configuration file, determines that the current fingerprint identification function of the terminal is forbidden, the processor does not process the fingerprint acquired by the fingerprint sensor or returns an indication of authentication failure to the application of the electronic wallet, and the application of the electronic wallet does not receive the response of the processor or receives the indication of authentication failure, so that the user cannot use the fingerprint authentication to quickly finish the authentication, and further cannot open the electronic wallet or use the functions of payment of the electronic wallet and the like.

After the fingerprint identification function is invalid, the user cannot use the fingerprint to quickly unlock the terminal for the terminal supporting fingerprint unlocking; for some applications that require fingerprint verification to open or use some functions, the user cannot use the fingerprint to quickly open or use some functions of the application. When the method is applied to the scenario 1, an illegal user cannot use the fingerprint of the user to perform fingerprint verification in the payment application, and only can input the password. Since passwords are typically composed of multiple digits, an illegal user may need to attempt to enter the password multiple times without knowing the password. Compared with the illegal user who attempts unlocking by using a fingerprint, the unlocking attempt by inputting the password has higher error rate and requires longer time for the unlocking attempt. Therefore, the time for unlocking the terminal can be prolonged, and the user can be won more sufficient fighting time.

According to the function control method provided by the embodiment of the application, the terminal disables the preset function including the biological feature recognition function after receiving the shortcut operation (first operation) input by the user. Therefore, in an emergency, the user can quickly disable the biological feature recognition function through quick operation, and the problem that privacy is easily revealed because the biological feature recognition function can realize quick identity verification is avoided.

At present, the types and the number of applications installed on a terminal by a user are increasing. Taking a mobile phone as an example, a user may install various payment applications such as "pay for you," "e-wallet," etc. on the mobile phone. The payment-type application generally stores information such as the account balance of the user. The user may also install an application program such as "gallery", "WeChat", "QQ" on the mobile phone, which stores the user's picture and the chat records with others. The user may also install game-like applications, etc. according to personal interests. In some application scenarios, during the process of using the terminal of the user 1 by the user 2, the user 1 does not want the user 2 to view some application programs, such as a "gallery" application and a game application installed on the terminal. In order to protect the private information of the user, in another implementation, the disabling the preset function further includes: the terminal disables the preset application program.

Wherein the preset application programs comprise one or more application programs which are preset by a user and are to be forbidden. The preset application programs also comprise one or more types of application programs to be forbidden, which are preset by a user. Or the preset application program comprises that the terminal sets some applications installed in the mobile phone as privacy applications by default, and after the first operation input by the user is detected, the terminal disables the privacy applications by default. After the terminal disables the preset application program through the input first operation, the terminal does not display the icon of the disabled application program on a setting interface, an application management interface or a homepage interface of the terminal. Therefore, after disabling the preset application, the terminal, from the user's perspective, cuts off the interface through which the user operates the preset application, which the user may think the terminal does not have installed.

In other implementation manners, after the terminal disables the preset programs, the icons of the preset application programs are displayed as grey on the terminal, and the terminal does not respond after the user clicks the application icon.

In a specific implementation, when the terminal receives a first operation input by a user, the terminal acquires a preset application program list set by the user, and modifies a configuration file of an application program in the preset application program list to set the state of the application program to be forbidden.

By the method, the user can set some application programs installed on the terminal as the application programs needing to be forbidden in advance, and when the terminal receives the quick operation of the user, the biological characteristic identification function is forbidden and the application programs preset by the user are forbidden at the same time, so that the privacy of the user can be protected.

Optionally, before the terminal receives the first operation input by the user, if the terminal is in the screen locking state. After the terminal disables the preset function according to the first operation, the method further includes: and the terminal releases the screen locking state and displays a first interface, wherein the first interface does not comprise the icon of the forbidden application program.

Optionally, before the terminal receives the first operation input by the user, if the terminal is in the screen locking state. After the terminal disables the preset function according to the first operation, the method further includes: the terminal receives a first unlocking password input by a user, and the first unlocking password is used for releasing the screen locking state of the terminal. And the terminal releases the screen locking state according to the first unlocking password and displays a first interface, wherein the first interface does not comprise the icon of the forbidden application program.

The first unlocking password may be a sliding gesture unlocking password or an unlocking password composed of character strings such as numbers and letters.

It should be noted that the first interface does not refer to an interface currently displayed by the terminal after the terminal is unlocked, but refers to a general name of all interfaces used for displaying icons of application programs installed in the terminal. When a plurality of application programs are installed in the terminal, the current display part of the first interface cannot simultaneously present icons of all the application programs to a user and only can present part of the application program icons due to limitation of a terminal screen. The user needs to slide the first interface left and right or up and down to view the icons of other application programs.

Through the implementation mode, if a user inputs a first operation when the terminal is in a screen locking state, the first operation can trigger the terminal to disable the preset function. The disabled function includes a biometric function, and thus, the user cannot use the biometric function. Then, since the terminal is still in the screen-locking state, the user needs to unlock the terminal by inputting an unlocking password or other means. And similarly, the first interface displayed by the unlocked terminal does not comprise the icon of the forbidden application program.

Optionally, after step 202 "the terminal disables the preset function according to the first operation", as shown in fig. 3, the method further includes the following steps:

301. the terminal receives a second operation input by the user.

The second operation input by the user comprises that the user presses a specific physical key, the user inputs a specific voice command, such as a voice command containing specific words of 'unlocking', and the like, the user inputs a preset gesture, the user inputs a password, the user moves the mobile phone along a specific direction, and the like. The second operation may also be other shortcut operations, and the embodiment of the present application does not limit a specific implementation of the second operation. Since the biometric function of the terminal has been disabled after the user has input the first operation, the second operation does not include an operation of the user to input a biometric feature such as a fingerprint. The embodiment of the present application does not limit the specific implementation of the second operation, where the second operation is used to trigger the terminal to recover the disabled function.

302. And the terminal restores the preset function according to the second operation input by the user.

And the preset recovering function comprises enabling the biological characteristic identification function by the terminal.

With the method shown in fig. 3, after the user disables the preset function through the first operation, the terminal receives a second operation of the user and restores the disabled preset function according to the second operation.

Illustratively, the second operation includes a second unlocking password input by the user after the terminal releases the screen locking state and displays the first interface. And the terminal recovers the biological characteristic identification function and removes the forbidding of the forbidden application program according to the second unlocking password, and displays a second interface. The second interface includes icons for all applications, including applications that have been disarmed.

The second unlocking password may be the same as the first unlocking password in implementation manner. For example: the second unlocking password can be a sliding gesture in a nine-grid format, and can also be a password composed of characters such as numbers and letters. The second unlocking password and the first unlocking password may be the same gesture or character password, but the first unlocking password and the second unlocking password have different functions. Specifically, after the terminal function is disabled but in the screen locking state, the user inputs a first unlocking password, and the purpose of the first unlocking password is to trigger the terminal to unlock. After the terminal function is disabled but in the unlocked state, the user enters the second unlocking password, which is intended to trigger the terminal to release the disabling of the disabled function.

Wherein the user can input the second unlocking password in a setting menu.

Optionally, before the terminal receives the first operation input by the user, if the terminal is in the screen locking state. The method further comprises: and the terminal receives a third operation input by the user, releases the screen locking state according to the third operation and displays a second interface, wherein the second interface comprises icons of all application programs.

The third operation comprises the steps that the user inputs specific biological feature recognition information, inputs specific gestures, specific passwords, specific voice instructions and the like. The third operation and the first operation may be implemented in the same or different manners. For example: the first operation is first preset biometric feature identification information, and the third operation is second preset biometric feature identification information. Also, the first operation is a first specific password and the third operation is a second specific password. For another example: the first operation is preset biological feature identification information, and the third operation is a specific password.

Through the implementation mode, when the terminal is in the screen locking state, if the user inputs the first operation, the terminal disables the preset function. If the user inputs the third operation, the terminal is normally unlocked.

In the following embodiments, a terminal is taken as a mobile phone, the first operation is a first preset fingerprint input by a user in a mobile phone screen locking state, the second operation is a password input by the user after the mobile phone is unlocked, and the third operation is a second preset fingerprint input by the user in the mobile phone screen locking state.

Before using the fingerprint to disable certain functions of the mobile phone, the user needs to enter the fingerprint to be used as a reference fingerprint in a subsequent process. At present, mobile phones generally have a fingerprint unlocking function, and based on the use habits and use experiences of users, the users can firstly input fingerprints for unlocking the mobile phones when using the mobile phones. In view of the new functionality provided to the handset by the user using the fingerprint to disable certain features of the handset, the user is prompted to continue entering a fingerprint for disabling certain features of the handset after the user enters a fingerprint for unlocking the handset (for ease of description, the fingerprint will be described below as a feature disabled fingerprint). Referring to fig. 4a, a user opens a setting interface 401 of the mobile phone, which displays options that the user can perform setting operations on the mobile phone, including whether to start a flight mode, establish a Wi-Fi connection, select a type of a mobile network, and set a fingerprint to be unlocked and disabled. After the user selects the option "unlock and disable function" in the interface 401, the mobile phone loads the interface 402, and the interface 402 displays prompt information asking the user whether to enter an unlock fingerprint. When the user clicks and confirms, the mobile phone displays the

interfaces

403 and 404 to prompt the user to enter the unlocking fingerprint, and after the unlocking fingerprint is successfully entered, the interface 405 is displayed to prompt the user that the entry of the unlocking fingerprint is completed and simultaneously prompt the user whether to continue to enter the function disabling fingerprint on the interface 405. When the user clicks on confirmation, the handset display interface 406 and interface 407 prompt the user to next enter a disabled functionality fingerprint, and upon successful entry of a disabled functionality fingerprint, display interface 408 prompts the user that the disabled functionality fingerprint has been successfully entered.

In other implementation manners, referring to fig. 4b, the mobile phone may add a function option of "function disable" in the setting menu, after the user opens the function option of "function disable" in the setting interface 501, the display interface 502 and the interface 503 prompt the user to enter a function disable fingerprint, and after the user successfully enters the function disable fingerprint, the display interface 408 prompts the user to finish entering the function disable fingerprint.

Referring to fig. 4c, upon successful entry of the functionally disabled fingerprint, the handset display interface 408 prompts the user that entry of the functionally disabled fingerprint has been completed. When receiving a confirmation operation of the user on the display interface 408, the display interface 601 prompts the user to set a biometric function to be disabled by default when the fingerprint is disabled using the function, including an "iris recognition function", a "face recognition function", a "fingerprint recognition function", and the like. When it is detected that the user selects to set the fingerprint recognition function as the function to be disabled by default at the interface 601, an interface 602 is displayed, which prompts the user that the "fingerprint recognition function" has been set as the function to be disabled by default when the user uses the function disabling fingerprint.

It should be noted that the user may set one or more of the "iris recognition function", "face recognition function", and "fingerprint recognition function" displayed on the interface 601 as functions to be disabled by default. For example: the user may simultaneously set both "iris recognition" and "fingerprint recognition" as functions to be disabled by default.

Optionally, besides disabling the fingerprint recognition function, the installed application program in the mobile phone may also be disabled according to the user requirement. In one example, referring to fig. 4d, upon receiving a confirmation operation input by the user at interface 602, interface 701 is displayed to ask the user whether to set the application to be disabled. When the user clicks the confirmation, the mobile phone displays an interface 703, the interface 703 displays all the application programs installed in the mobile phone, the user can select to set some of the application programs as APPs to be disabled, and the interface 703 takes "WeChat" and "Paibao" as examples for explanation.

In another example, referring to fig. 4e, after receiving a confirmation operation input by the user at the interface 602, the mobile phone displays an interface 801, the interface 801 displays various types of applications installed in the mobile phone, including a "chat-type application", a "payment-type application", and a "game-type application", and the user may set applications to be disabled in each type of applications in turn. Illustratively, a user clicks an option on the right side of the "payment application", the mobile phone loads the interface 802, the interface 802 displays all payment applications installed in the mobile phone, the user can select all the payment applications to set all the payment applications as preset forbidden application programs, or only select part of the payment applications, in the figure, the user selects "pay treasure" and "money bank", for example, when the user clicks "complete", the interface 802 "disappears", the mobile phone returns to the interface 801, and the user can select an application to be forbidden from other applications. When the user clicks the confirmation operation on the interface 801, the mobile phone display interface 803 prompts the user that the setting of the application to be disabled has been completed.

To facilitate the user's disablement of the functionality, the user is prompted to set a password for disablement of the functionality before or after the user enters the fingerprint of the functionality disablement. Referring to fig. 4f, after the user clicks on the confirmation operation at the interface 803, the handset display interface 901 prompts the user to continue to set a password for releasing the disabling of the disabled function. After receiving the confirmation operation of the user on the interface 901, the mobile phone displays the interface 902, and the user can input the password for releasing the disabling on the interface 902. After the password is successfully set, the mobile phone displays the interface 903 to prompt the user that the password is successfully set.

After the user completes entering the fingerprint with disabled function, removing the password with disabled function and setting the biological feature recognition function and the application program to be disabled according to the setting operation of fig. 4a to 4f, when the mobile phone detects the fingerprint input by the user, the mobile phone compares the fingerprint input by the user with the fingerprint with disabled function entered by the user, if the fingerprint is consistent, the identity verification is successful, and then the mobile phone disables the preset application program and the fingerprint recognition function. The user may disable the function by entering a password.

As shown in fig. 5, the method provided by the embodiment of the present application includes the following steps:

1001. the mobile phone receives the operation input by the user on the screen locking interface.

When the operation is that the user inputs a password, the following step 1010 is executed. When the operation is a user inputting a fingerprint, the following step 1002 is performed.

1002. The mobile phone compares the fingerprint input by the user on the screen locking interface with a first preset fingerprint.

In consideration of the fact that the fingerprint input by the user may be an unlocking fingerprint or a function forbidden fingerprint when the mobile phone detects the fingerprint input by the user on the screen locking interface, the mobile phone needs to identify the fingerprint and execute corresponding operation according to an identification result after detecting the fingerprint input by the user on the screen locking interface.

The first preset fingerprint is a function forbidden fingerprint input by a user in advance.

In this step, if the fingerprint input by the user on the screen locking interface is consistent with the first preset fingerprint, it indicates that the fingerprint input by the user is a function disabled fingerprint, and the mobile phone performs the following step 1004. If the fingerprint input by the user on the screen locking interface is not consistent with the first preset fingerprint, the mobile phone executes the following step 1003 to further compare the fingerprint with the unlocking fingerprint, and executes corresponding steps according to the comparison result.

1003. And the mobile phone compares the fingerprint input by the user on the screen locking interface with a second preset fingerprint.

And the second preset fingerprint is an unlocking fingerprint input by the user in advance.

In this step, if the fingerprint is consistent with the second preset fingerprint, which indicates that the fingerprint input by the user is an unlock fingerprint, the mobile phone performs step 1008 described below. If the fingerprint is not consistent with the second preset fingerprint, the mobile phone performs the following step 1009 to prompt the user to input the fingerprint again to unlock the terminal.

1004. The mobile phone disables the fingerprint identification function and the preset application program.

Optionally, before disabling the fingerprint recognition function and presetting the application program, the mobile phone pops up a prompt box to prompt the user whether to start the function disabling, if the user confirms to start, the mobile phone executes the step 1004, otherwise, the mobile phone does not start the function disabling.

Optionally, after this step 1004, the terminal issues a prompt message to prompt the user that the preset application and the fingerprint recognition function have been successfully disabled. The prompting mode comprises the following steps: vibration prompt, indicator light flashing and the like, prompt information displayed on a mobile phone interface and the like.

1005. The mobile phone receives an unlocking password input by a user.

After the fingerprint identification function of the mobile phone is forbidden, if a user wants to unlock the mobile phone, the user needs to input an unlocking password, and the mobile phone is unlocked in a password mode.

It should be noted that the step 1005 is an optional step. In other implementations, the handset can perform the step 1006 directly after performing the step 1004.

1006. And the mobile phone displays the unlocked first interface, and the interface does not display the forbidden icon of the preset application program.

After the mobile phone is unlocked, the unlocked interface only presents icons of part of application programs, and does not present the icons of the forbidden application programs.

1007. The mobile phone receives a password for releasing the forbidding input by the user.

After the mobile phone disables the fingerprint recognition function, the user may input a password for releasing the disabling to release the disabling of the preset function.

1008. And displaying the unlocked second interface by the mobile phone, wherein the interface displays the icon of the preset application program.

Illustratively, the application disabled in step 1004 is a payment treasure, a tenderer bank, etc., and the display of the icon of the payment application of the payment treasure, tenderer bank, etc. is resumed in this step.

1009. The mobile phone prompts the user to input the unlocking fingerprint again to unlock the terminal.

It should be noted that the step 1003 may be executed after the step 1002 or before the step 1002; it may also be performed simultaneously with step 1002. The execution order of step 1002 and step 1003 is not limited in the embodiments of the present application.

1010. The mobile phone compares the password input by the user on the screen locking interface with a preset unlocking password.

The preset unlocking password is a password which is input by a user in advance and used for removing the function disablement, for example, a schematic process diagram of inputting the function disablement password by the user shown in fig. 4f is shown.

If the password input by the user is consistent with the preset unlocking password, indicating that the password input by the user is the unlocking password, the mobile phone executes the following step 1103. If the password input by the user is not consistent with the preset unlocking password, the mobile phone executes step 1012 to prompt the user to input the unlocking password again to unlock the mobile phone.

1011. The mobile phone judges whether the fingerprint forbidding function is started currently.

If the handset has the fingerprint disable function enabled, then step 1006 is performed, otherwise step 1008 is performed.

1012. The mobile phone prompts the user to input the unlocking password again to unlock the mobile phone.

To more clearly illustrate the method shown in fig. 5, referring to fig. 5a, after the user inputs a fingerprint in the lock screen interface, the mobile phone compares the fingerprint with the unlock fingerprint and the function disable fingerprint, respectively. If the fingerprint is consistent with the unlocking fingerprint, the mobile phone unlocks and loads an interface shown as 1103, and icons of all the application programs installed by the user are displayed in the interface. If the fingerprint is consistent with the fingerprint with disabled function, displaying the interface 1102, popping up a prompt box, and prompting the user whether to disable the fingerprint identification function and preset the application program, i.e. to start the function with disabled function. And after the user selects and confirms, the mobile phone disables the fingerprint identification function and the preset application program. Then, because the mobile phone is in the unlocked state, if the user wants to unlock the mobile phone, the user needs to input an unlocking password on the screen locking interface because the user cannot use the fingerprint identification function.

Optionally, after the user selects the confirmation operation on the interface 1102 and the mobile phone starts the function of disabling the function, the mobile phone pops up a prompt box (the interface is not shown in fig. 5 a) to prompt the user that the fingerprint recognition function and the preset application program are disabled.

Referring to fig. 5b, when the user inputs an unlocking password in the screen locking interface 1104, after the user inputs a correct unlocking password to unlock successfully, if the mobile phone does not turn on the function disabling function, the mobile phone loads the unlocked interface 1103. If the mobile phone has enabled the disabled functionality, the mobile phone loads the unlocked interface 1105.

Taking the example that the application program to be disabled preset by the user includes a WeChat and a Payment treasure, compared with the unlocked interface 1105, icons of the application programs such as the WeChat and the Payment treasure are not displayed in the interface 1103 but only displayed in the interface 1105.

Referring to fig. 5c, the user clicks the "set" option in the unlocked interface 1105, and the handset loads the interface 1106. After the user selects the option of "function disabled" in the interface 1106, the mobile phone displays an interface 1107 for the user to input a password, and when the password input by the user is consistent with the password which is input in advance to remove the function disabled, the mobile phone displays an interface 1103, that is, the icons of "WeChat" and "Paibao" are restored.
