     DETAILED DESCRIPTION 
     The present disclosure provides in some embodiments a method for security verification, an apparatus for security verification and a mobile terminal. 
     To enable a person skilled in the art to better understand the technical solution of the present disclosure, the following clearly and completely describes the technical solutions in some embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are merely a part rather than all of the embodiments of the present disclosure. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the scope of the present disclosure. 
     Compared with a gesture password, a character password, or the like commonly seen in the related art, security can be significantly enhanced by fingerprint recognition. However, in some special scenarios, for example, when a user is unconscious (for example, the user is asleep, is in a coma, loses motor function, or the like) or the user is in a conscious but coerced/forced state, the user may be forced to perform a biometric recognition unlocking or payment (for example, fingerprint unlocking, fingerprint payment, or the like) operation. In these cases, a terminal device of the user may perform the foregoing operation, thereby causing user information leakage or even an economic loss. 
     The present disclosure provides in some embodiments a method for security verification, to solve the problem in the related art that user information leakage or even an economic loss may be caused in a scenario of an involuntary identity verification. 
       FIG. 1  is a flowchart of a method for security verification according to some embodiments of the present disclosure. The method for security verification may be performed by a terminal device. The terminal device may be a device such as a personal computer (PC), or may be a mobile terminal device such as a mobile phone, or a tablet computer. The terminal device may be a terminal device used by a user. The method is applicable to biometric recognition verification of a terminal device, user identity, or the like; further, the method is applicable to disablement or invalidation of currently used biometric recognition verification information in a terminal device, or the like. The method may specifically include the following steps S 102 , S 104 , and S 106 . 
     The step S 102  includes: determining whether a received touchscreen operation is a predetermined operation. 
     There may be a plurality of touchscreen operations, which may be specifically set according to an actual situation, and specifically includes, for example, a tap, a swipe, a press (which may include a press at any position in a current display interface, a press at a specified position in a current display interface, and the like), a multi-touch (which may include, for example, a five-finger pinch, a three-finger swipe), multiple consecutive taps, a gesture based on a writing symbol (for example, a gesture drawing the symbol “S”, or the like), or the like. The predetermined operation may be any one or combination of two or more of abovementioned touchscreen operations, and may be, for example, one of a press, a multi-touch, multiple consecutive taps, and a gesture based on a writing symbol, or a combination of two or more of a press, a multi-touch, multiple consecutive taps, and a gesture based on a writing symbol. 
     In an implementation, with the ongoing development of terminal technology, a terminal device, especially a mobile phone, becomes the device that is most frequently used and on which the most time is spent. To ensure the security of information stored in the terminal device, it is usually necessary to perform verification before access to information specified by a user or having a relatively high security requirement is allowed. For this purpose, the user may set verification information (for example, a password, or the like) in the terminal device. Taking the screen unlocking of the terminal device as an example, because the screen of the terminal device occupies an increasingly large proportion of area in the terminal device, to prevent the screen from being accidentally touched and improve the security of user data stored in the terminal device, the screen of the terminal device is usually locked when the user is not using the terminal device, and an unlocking password is also set for the screen of the terminal device. To further improve the security and convenience of the terminal device, the user may usually set an unlocking password based on biometric recognition. That is, the user sets a password (that is, verification information) including a character and/or gesture pattern, and registers personal biometric recognition verification information (for example, fingerprint verification information, facial verification information, iris verification information, or the like). In this way, the user may unlock the locked screen of the terminal device by using the registered biometric recognition verification information. Based on the foregoing process, the user may establish a verification mode for unlocking the screen of the terminal device. The biometric recognition verification information may be used to verify the identity of the user. The corresponding verification mode may be, for example, fingerprint verification, vein (including finger vein, or the like) verification, hand-shape verification, palm print verification, retina verification, ear verification, facial verification, iris verification, or the like. The aforementioned biometric recognition verification modes may be used to unlock the screen of the terminal device, or may be used to unlock a file, data, or the like stored in the terminal device, or may be used for application program launch verification, online payment verification, or the like. 
     To further ensure the security of information stored in the terminal device, various different verification information or verification modes may be set in the terminal device. Different verification information may be used to implement different functions or complete different operations. For example, a biometric recognition module is used to establish biometric recognition verification information for unlocking the screen of the terminal device, and a shortcut operation (for example, a touchscreen operation, or the like) for disabling or invalidating the biometric recognition module may further be established, or, a shortcut operation for switching to another verification mode is provided, or, a screen locking operation and/or other operation is performed. In a practical application, taking the screen unlocking of the terminal device as an example, when the user needs to unlock the screen, the screen of the terminal device may be turned on, and the terminal device may display a verification page. The verification page may provide a plurality of verification modes for the user to select, for example, verification through password including characters, verification through a gesture pattern, biometric recognition verification, and the like. At this time, the terminal device may detect an operation of the user to determine whether the user needs to undergo biometric recognition verification. If an indication that the user triggers a biometric recognition verification mechanism is received, it is determined that the user needs to undergo biometric recognition verification, so that the user may undergo the biometric recognition verification. Taking the biometric recognition verification being fingerprint verification for example, if an indication that the user places a finger in an area corresponding to a fingerprint capturing component is received, it is determined that the user needs to undergo fingerprint verification (that is, the biometric recognition verification). 
     The terminal device may further store the predetermined operation to perform in the process of biometric recognition verification. If it is determined that the user needs to undergo biometric recognition verification, the terminal device may detect the touchscreen operation of the user in real time. If the user does not want current biometric recognition verification to succeed, or in the case that the user may not want to perform biometric recognition verification for the sake of another person since the current biometric recognition verification is against the user&#39;s will (for example, the user is in an unconscious state (for example, the user is asleep, is in a coma or loses motor function) or the user is in a conscious but coerced/forced state, or the like), the user may perform the touchscreen operation in a display interface of the terminal device, the terminal device may acquire and/or record the touchscreen operation in real time, and compare the touchscreen operation with the predetermined operation, to determine whether the touchscreen operation input by the user is the predetermined operation. 
     In addition, the matter requiring biometric recognition verification is not limited to the screen unlocking of the terminal device, and may also be the launch of an application program, payment verification in a transaction process, or the like. Launch verification of an application program may specifically include the following process: the user may preset a processing mechanism of biometric recognition verification for the launch of one or more application programs. For a specific setting process, reference may be made to the foregoing verification setting process of screen unlocking. Details thereof are not described herein again. When the user needs to use an application program, the user may tap a corresponding application program shortcut icon in the terminal device. If the terminal device determines that the application program requires verification, a verification page may be displayed before the application program is launched. If an indication that the user triggers a biometric recognition verification mechanism is received, it is determined that the user needs to undergo biometric recognition verification. In this case, the user may undergo biometric recognition verification. For payment verification in a transaction process and verification for other matter, reference may be made to the foregoing related description. Details are not given herein again. 
     If it is determined that biometric recognition verification is not needed, the terminal device may perform verification processing according to a verification mechanism (i.e., a non-biometric recognition verification mechanism, such as a verification mechanism through a password including characters, and/or a verification mechanism through a gesture pattern) triggered by the user. 
     The step  5104  includes: acquiring biometric recognition verification information input by a user if the touchscreen operation is not the predetermined operation, and verifying the biometric recognition verification information. 
     In an implementation, if it is determined that the touchscreen operation is not the predetermined operation by comparing the touchscreen operation input by the user with the predetermined operation, the terminal device may perform biometric recognition verification processing normally. During the process of undergoing biometric recognition verification, the user may input biometric recognition verification information in a verification information input page displayed during the biometric recognition verification. After acquiring the biometric recognition verification information input by the user, the terminal device may search verification information pre-stored in the terminal device for verification information matching the biometric recognition verification information input by the user. The terminal device may determine that current verification succeeds if the terminal device determines that the biometric recognition verification information input by the user matches the set verification information. The terminal device may determine that current verification fails if the biometric recognition verification information input by the user does not match the set verification information. 
     In a practical application, after verification succeeds, the terminal device may further perform an operation that needs to be performed after the verification succeeds. Then the terminal device may be triggered to perform an operation according to an operation corresponding to first verification information. The performed operation may be set according to an actual situation, and includes, for example, an unlocking operation, an identity verification operation, a payment verification operation, a locking operation, a deactivation operation, transmission of preset information to a target device, or the like. The target device may be a terminal device, a server or the like. The preset information may be information preset by the user, positioning information (for example, current geographical location of the terminal device, relative location of the terminal device with respect to the user, or the like), information generated by the terminal device according to a preset rule, or the like. This is not limited in embodiments of the present disclosure. Taking a screen unlocking process of the terminal device for example, the terminal device may unlock the screen if the biometric recognition verification information input by the user matches biometric recognition verification information for unlocking the screen. Then, the user may view the home interface displayed by the terminal device. 
     The step  5106  includes: performing verification processing corresponding to the predetermined operation if the touchscreen operation is the predetermined operation. 
     There may be plural types of verification processing corresponding to the predetermined operation. The verification processing includes, for example, disabling the biometric recognition module, invalidating a biometric recognition verification function, turning off or locking the terminal device, transmitting preset information (for example, positioning information, a verification code, or the like) to a target device, or the like. 
     In an implementation, the terminal device may acquire and/or record the touchscreen operation in real time, and match the touchscreen operation against the pre-stored predetermined operation. If the touchscreen operation matches the predetermined operation, the terminal device may still display a biometric recognition verification page and prompt the user to input biometric recognition verification information. In this case, the user may input the biometric recognition verification information again. Even if the current input biometric recognition verification information is correct, the terminal device still determines that current verification fails. As can be learned from the above description, if the terminal device receives a touchscreen operation performed by the user during biometric recognition verification and the touchscreen operation is the predetermined operation, then regardless of whether the biometric recognition verification information input by the user is accurate, the terminal device determines that the verification fails, so as to protect personal information when the verification is against the user&#39;s will. 
     In a practical application, when biometric recognition verification is needed, if a touchscreen operation performed by the user is received and the touchscreen operation is the predetermined operation, the terminal device may further continue to perform an operation that needs to be performed after verification fails, wherein the performed operation may be set according to an actual situation and may include, for example, locking the terminal device, turning off the terminal device, transmitting preset information to a target device, or the like. The target device may be a terminal device, a server, or the like. The preset information may be information preset by the user, positioning information (for example, current geographical location of the terminal device, relative location of the terminal device with respect to the user, or the like), information generated by the terminal device according to a preset rule, or the like. This is not limited in embodiments of the present disclosure. Still taking a screen unlocking process of the terminal device for example, when biometric recognition verification is needed, if a touchscreen operation performed by the user is received and the touchscreen operation is the predetermined operation, the terminal device no longer unlocks the screen, instead the terminal device still displays a biometric recognition verification screen. If the user inputs first verification information (that is, a fingerprint, facial data, a voiceprint, iris data, or the like) again, the terminal device may determine that current verification fails. In this case, for example, the terminal device may be triggered to lock information related to the user to prevent a loss of the information, or the terminal device may be triggered to turn off the touchscreen or perform a power-off operation, or the like. 
     In the method for security verification provided in some embodiments of the present disclosure, it is determined whether a received touchscreen operation is a predetermined operation, then corresponding verification processing is performed. That is, if the touchscreen operation is not the predetermined operation, biometric recognition verification information input by a user is acquired and the biometric recognition verification information is verified; if the touchscreen operation is the predetermined operation, verification processing corresponding to the predetermined operation is performed. In this way, a set predetermined touchscreen operation is used to control whether biometric recognition verification succeeds. For example, when a situation where the identity verification may be against the user&#39;s will is encountered, the user may use the predetermined touchscreen operation to make the biometric recognition verification for unlocking, payment or the like to fail, so that it is ensured that no leakage of file or data stored in a terminal device would occur, thereby improving the security of user information and property. 
       FIG. 2  is another flowchart of a method for security verification according to some embodiments of the present disclosure. The method for security verification may be performed by a terminal device. The terminal device may be a device such as a PC or may be a mobile terminal device such as a mobile phone or a tablet computer. The terminal device may be a terminal device used by a user. The method is applicable to biometric recognition verification of a terminal device, user identity, or the like; further, the method is applicable to disablement or invalidation of currently used biometric recognition verification information in a terminal device, or the like. 
     A process of disabling or invalidating the biometric recognition verification information currently used in the terminal device or a verification mode corresponding to the biometric recognition verification information is described in detail in the embodiment. In some special occasions (for example, when the user is in an unconscious state (for example, the user is asleep, is in a coma or loses motor function), the user is in a conscious but coerced/forced state (for example, the user encounters a pyramid scheme, robbery, or the like), or the like), another person may use the user&#39;s fingerprint, face or iris to undergo biometric recognition verification. For example, in some special occasions, another person wants to unlock the screen of the terminal device of the user. In this case, if the terminal device prompts the user to input a fingerprint, another person may use the user&#39;s finger to input a fingerprint or force the user to input his fingerprint to perform unlocking, thereby possibly leading to the leakage of personal information of the user. Similarly, the foregoing problem also exists for other biometric recognition verification such as facial verification, voiceprint verification, iris verification, and the like. In view of this, the embodiment provides a processing method for disabling or invalidating biometric recognition verification information or a verification mode corresponding to the biometric recognition verification information. The method may specifically include the following steps S 202  to S 232 . 
     The step S 202  includes: determining whether a received touchscreen operation is a predetermined operation. 
     In an implementation, taking a common screen unlocking process of the terminal device for example, if the first verification information is a fingerprint, the operation corresponding to the first verification information is unlocking the screen. Generally, in the normal usage of the terminal device, a fingerprint unlocking mode for the screen of the terminal device is in an active state. That is, when the user does not need to use the terminal device, the user may lock the screen of a mobile phone by pressing the power button or another designated button briefly. In this case, the terminal device turns off the screen. As shown in  FIG. 3 , when the user needs to use the terminal device again, the user may press the power button or another designated button briefly, and the terminal device will turn on the screen and display an unlocking prompt. At this point, the user may press a finger corresponding to the fingerprint for unlocking on the fingerprint capturing component of the terminal device. The terminal device may capture fingerprint data of the finger via the fingerprint capturing component. The captured fingerprint data may be used as the biometric recognition verification information for comparison with the first verification information corresponding to fingerprint data registered by the user in advance. If the two match, the screen of the terminal device is unlocked. If the two do not match, a prompt sound or prompt information is output to inform the user that unlocking fails. In this case, the user may input the biometric recognition verification information, i.e., fingerprint data, again. When all attempts of the user to use the fingerprint unlocking mode to unlock the screen of the terminal device fail and the number of failures reaches a predetermined threshold, the fingerprint unlocking mode for the screen of the terminal device is no longer active or is disabled. That is, at this time, the screen of the terminal device cannot be unlocked even if the user inputs correct fingerprint data, and the screen can only be unlocked by using another verification mode provided by the terminal device, for example, by inputting a. character and/or a gesture pattern. In addition, in a practical application, there may be other implementations of invalidating or disabling the fingerprint unlocking mode for the screen of the terminal device. For example, after the terminal device is restarted, the fingerprint unlocking mode for the screen of the terminal device is invalidated or disabled, and when the user needs to access the home interface of the terminal device, the user cannot use a fingerprint to unlock the screen, but can only unlock the screen by inputting a character and/or a gesture pattern. 
     However, the foregoing two manners of invalidating or disabling a verification mode currently used in a terminal device or a default verification mode can only be implemented in specific conditions or specific occasions. To prevent another user from illegally acquiring information stored in the terminal device, a mechanism for invalidating or disabling currently-used or default biometric recognition verification information in the terminal device or a corresponding verification mode may be set. The mechanism may specifically include the following process: a setting page for the invalidation or disablement of the biometric recognition verification information or a verification mode corresponding to the biometric recognition verification information may be provided in the terminal device. The setting page may include: a setting option of the predetermined operation for disabling the biometric recognition verification information or a verification mode corresponding to the biometric recognition verification information, a level for disabling the biometric recognition verification information or a verification mode corresponding to the biometric recognition verification information (which may be referred to as a disablement level for ease of subsequent description), an OK button, a Cancel button, and the like. As shown in  FIG. 4 , when a user needs to perform setting regarding the disablement of current biometric recognition verification information or a verification mode corresponding to the biometric recognition verification information, the user may open the setting page. The user may locate a setting option of the predetermined operation on the setting page and tap the setting option, and the terminal device may activate a corresponding sensor. The user may then input the predetermined operation in current display interface. For example, the user presses at a position in the current display interface, which may specifically be a press-finger prompt area. In this case, the terminal device may detect and record the position and intensity of the press in the area by using the sensor. For another example, the user draws a specific symbol in the current display interface. Specifically, the user draws a symbol “S” in the current display interface. In this case, the terminal device may use the sensor to detect and record the symbol drawn by the user. After completing the input, the user may tap the Ok button or a Store button. The terminal device may use the touchscreen operation input by the user as the predetermined operation. The user may then select a disablement level. The disablement level may be set according to the user&#39;s requirement. For example, the disablement level may include: temporary disablement, disabled for preset first duration, deletion of a biometric feature (including first verification information) corresponding to a biometric recognition module, and the like. In the case of the temporary disablement, the user may use a password formed by characters to revoke the disablement. The disabled for preset first duration includes, for example, disabled for  12  hours, disabled for  24  hours, or the like. After selecting the disablement level, the user may tap the OK button in the setting page. The terminal device may acquire the data input by the user in the setting page and store the data. 
     It should be noted that, to make the touchscreen operation of the user as subtle as possible and reduce unnecessary trouble that may occur subsequently, during the setting of the predetermined operation, the predetermined operation should be as simple as possible and can be easily memorized by the user. 
     When another person wants the user to input first verification information to perform an operation corresponding to the first verification information, the screen of the terminal device may be turned on, and the terminal device displays a biometric recognition verification screen. If the user does not want another person to view content stored in the terminal device, the user may perform the touchscreen operation in the current display interface. In this case, the terminal device may activate a corresponding sensor. For example, if the predetermined operation is a press, the terminal device may activate a pressure sensor. If the predetermined operation is a gesture operation for inputting a character, the terminal device may activate a touchscreen sensor. The touchscreen operation of the user may be detected by using the sensor, and the acquired touchscreen operation may be compared with the predetermined operation to determine whether the acquired touchscreen operation is the predetermined operation. if it is determined that the touchscreen operation is the predetermined operation, the processing of the following step S 204  to step S 228  may be performed. If it is determined that the touchscreen operation is not the predetermined operation, the processing of the following step S 230  to step S 232  may be performed. 
     In case that the touchscreen operation is the predetermined operation, the terminal device may disable the biometric recognition module (the biometric recognition module may be a component for biometric recognition verification, for example, the fingerprint capturing component in  FIG. 3 , and if the biometric recognition module is disabled, the user cannot undergo biometric recognition verification). After the biometric recognition module is disabled, corresponding processing may be performed according to foregoing different disablement levels. Specifically, if the disablement level is the temporary disablement, the terminal device may disable the biometric recognition module. If the user needs to restore a biometric recognition function, the user may use non-biometric recognition verification information (for example, a password formed by characters or a password formed by a gesture pattern) to revoke the disablement of the biometric recognition module. For details, reference may be made to the following step S 204  to step S 212 . 
     In addition, the application of the first verification information is not limited to the fingerprint unlocking mode for the screen of the terminal device. The first verification information may further be applied to a fingerprint unlocking mode for launching an application program, fingerprint verification mode for payment in a transaction process, or the like. The fingerprint unlocking mode for launching an application program may specifically include the following content: the user may preset a processing mechanism that the launch of one or more application programs requires the user to unlock the application program. For a specific setting process, reference may be made to the foregoing setting process of a fingerprint unlocking mode for the screen. Details thereof are not described herein again. When the user needs to use the application program, the user may tap a corresponding application program shortcut icon in the terminal device. If the terminal device determines that the application program requires fingerprint unlocking, prompt information used to prompt the user to input a fingerprint or an unlocking password may be displayed before the application program is launched. At this point, the user may input verification information. For a fingerprint verification mode for payment in a transaction process and a fingerprint unlocking mode for other matter, reference may be made to the foregoing description of processing. Details thereof are not described herein again. 
     The step S 204  includes: acquiring biometric recognition verification information input by a user if the touchscreen operation is the predetermined operation, and determining that the verification fails when the acquired biometric recognition verification information matches preset first verification information. 
     In an implementation, when the terminal device receives the touchscreen operation of the user, the terminal device may match the touchscreen operation against the predetermined operation for invalidating or disabling the first verification information or a verification mode corresponding to the first verification information (that is, invalidating or disabling fingerprint verification, or disabling the biometric recognition module). If the terminal device determines through the matching that the touchscreen operation of the user is the predetermined operation for disabling the biometric recognition module, the biometric recognition module (for example, the fingerprint capturing component) is set to an invalidated or disabled state. In this case, a verification page may still be displayed, and the biometric recognition verification page continues to be used to acquire the biometric recognition verification information input by the user. When the acquired biometric recognition verification information matches the preset first verification information, it is determined that verification fails. That is, in this case, regardless of whether the biometric recognition verification information corresponding to the fingerprint data. input by the user is the first verification information, the terminal device cannot perform the operation corresponding to the first verification information, i.e., unlocking the screen (or launching an application program). At the same time, a target object (for example, the screen or a file) requiring biometric recognition verification is locked by the terminal device. In this way, the terminal device cannot unlock the target object no matter what fingerprint data is input by the user at the request of another person, thereby it is ensured that the data or target object stored in the terminal device remains in a secure state. 
     In addition, in the case that a touchscreen operation performed by the user is received and the touchscreen operation is the predetermined operation, in order to restore a normal biometric recognition verification function of the terminal device (that is, to revalidate the fingerprint verification mode), if the disablement level of the biometric recognition module is the temporary disablement, the biometric recognition verification function may be restored (or the disablement of the biometric recognition module may be revoked) in a plurality of manners. The following provides an optional processing manner, which may specifically include the following step S 206  to step S 212 . 
     The step S 206  includes: acquiring identity information input by the user if the touchscreen operation is the predetermined operation. 
     The identity information may be information used to represent user&#39;s identity, and includes, for example, a specified identification number (for example, identity card number and the like) of the user, a character password preset by the user, or the like. Considering that a person has a limited quantity of fingerprints, in order to prevent a situation that verification succeeds as a result of coerced verification attempts using each finger of the user, thereby causing a loss for the user, the identity information may be set to be different in kind from the biometric recognition verification information for security verification. That is, if the biometric recognition verification information is formed by fingerprint data, the identity information may be formed by any data other than fingerprint data. For example, the identity data is formed by characters, facial data, or the like. 
     There may he various specific processing manners of step S 206  in a practical application. The following provides an optional processing manner, which may specifically include the following substep  1  and substep  2 . 
     The substep  1  includes: displaying an identity verification page and transmitting the identity information to the target device if the touchscreen operation is the predetermined operation. 
     The identity verification page may be a page used to prompt the user to undergo an identity verification. The identity verification page may include a plurality pieces of information and/or a plurality of buttons. For example, if the identity information is formed by characters, as shown in  FIG. 3 , the identity verification page may include numeric keys or letter keys. Optionally, the identity verification page may include prompt information, which may include information for instructing the user to perform an operation, such as “swipe up to unlock” or “unlock with fingerprint”. Optionally, if the identity information is formed by data of a gesture operation of the user, the identity verification page may include a plurality of (for example, 9) dots or circles arranged regularly, to prompt the user to input a gesture pattern or the like. The identity information may be information different (in kind and content) from the first verification information for a target object that requires biometric recognition verification. The identity information may be temporary unlocking information used to revalidate the first verification information or a verification mode corresponding to the first verification information (that is, fingerprint unlocking or fingerprint payment verification) when the first verification information or the verification mode corresponding to the first verification information is disabled. For example, the identity information may be ht325yg, 293847, or the like. The target device may be a preset device different from the terminal device used by the user. For example, the target device is another terminal device of the user, a terminal device used by a friend or family member of the user, or the like. 
     In an implementation, if the terminal device receives a touchscreen operation performed by the user and the touchscreen operation is the predetermined operation, it may be determined that a target object that is stored in the terminal device and requires biometric recognition verification is at risk. In this case, for the security of the target object, the biometric recognition module may be set to a disabled (or invalidated) state, and the target object is locked (for specific processing, reference may be made to the foregoing description). In addition, the terminal device may use a preset unlocking rule to generate identity information, and may transmit the identity information to a preset target device by means of a short message, speech data, or the like. In addition, the identity information may further be preset by the user. In a practical application, the user may set a plurality pieces of different temporary unlocking information, from which the terminal device may choose one piece of temporary unlocking information as the identity information. For example, the user presets a plurality pairs of question and answer (that is, the user sets a plurality of questions and sets one answer to each question) as temporary unlocking information. The terminal device may select one question, provide the question to the user, and compare an answer input by the user with a preset answer to determine whether verification succeeds. 
     The substep  2  includes: acquiring the identity information input by the user on the identity verification screen. 
     In an implementation, to facilitate the user to input the identity information, the terminal device may display an identity verification page so that the user may input the identity information to perform an unlocking operation. 
     The step S 208  includes: determining that the verification succeeds if the identity information matches preset second verification information. 
     The second verification information may be set according to an actual situation. 
     In an implementation, if the user needs to unlock a target object, second verification information may be acquired from the target device or preset second verification information may be determined. The user may then input the identity information corresponding to the second verification information on the identity verification page displayed by the terminal device. After input is completed, the user may tap the OK button on the identity verification screen, or it may be determined that the input of the user is completed if the terminal device has not detected a tap on the identity verification page for predetermined duration. The terminal device may acquire the identity information input by the user. The terminal device may match the identity information against the second verification information. If the identity information matches the second verification information, the biometric recognition module may be switched from a disabled state to an active state. In this case, the terminal device may unlock the target object and may acquire information related to the target object, for example, display the home interface of the terminal device, launch the predetermined application program, or the like. 
     It should be noted that, the processing of the foregoing step S 208  may be implemented in a variety of manners besides the foregoing manner. The following further provides an optional processing manner, which may specifically include the following process: if the identity information matches the second verification information, the biometric recognition module may be switched from a disabled state to an active state. At this point, the user may undergo verification using the first verification information to unlock the target object. The terminal device may acquire information related to the target object. For details, reference may be made to the processing of the following step S 210  and step S 212 . 
     By means of the processing of the foregoing step S 208 , the biometric recognition verification function of the terminal device may be restored (that is, the biometric recognition module operates normally). In a next security verification process, the terminal device may implement the following step S 210  and step S 212 . 
     The step S 210  includes: acquiring the biometric recognition verification information input by the user. 
     The step S 212  includes: determining that the verification succeeds if the biometric recognition verification information acquired in the foregoing step S 210  matches preset first verification information. 
     For a specific processing process of the foregoing step S 210  and step S 212 , reference may be made to the related description of step S 104  in the foregoing embodiment. Details thereof are not described herein again. 
     In addition, the processing manner of the foregoing step S 204  to step S 212  is only a possible implementation of some embodiments of the present disclosure. In a practical application, there may be a plurality of implementations. The following further provides an optional implementation, which may specifically include the following step S 214  to step S 218 . 
     The step S 214  includes: disabling the biometric recognition module so that the biometric recognition module is unavailable for preset first duration if the touchscreen operation is the predetermined operation. 
     The first duration may be set according to an actual situation, and includes specifically, 12 hours, 24 hours, or the like. 
     In an implementation, if the disablement level of the biometric recognition module preset by the user in the terminal device is the disabled for preset first duration, when the terminal device acquires the touchscreen operation of the user and determines that the touchscreen operation is the predetermined operation, the terminal device may determine that the user wants to disable the biometric recognition module. In this case, the terminal device may perform processing of disabling the biometric recognition module, to prevent the biometric recognition module from acquiring the biometric recognition verification information. In this way, the user cannot pass verification by using the biometric recognition verification information. In addition, if the disablement level currently set in the terminal device is the disabled for preset first duration, the terminal device may stop normal operation of the biometric recognition module. 
     In addition, in a case that the disablement level is the disabled for preset first duration, after the biometric recognition module has been disabled for the preset first duration, the terminal device may restore normal operation of the biometric recognition module, which may specifically include the following step S 216  and step S 218 . 
     The step S 216  includes: starting timing when it is determined that the acquired touchscreen operation is the predetermined operation, and acquiring biometric recognition verification information input by a user after the preset first duration is reached. 
     In an implementation, the terminal device starts timing when a touchscreen operation performed by the user is received and it is determined that the touchscreen operation is the predetermined operation. After the predetermined duration is reached, the terminal device may automatically revoke the disablement of the biometric recognition verification information or a verification mode corresponding to the biometric recognition verification information, so as to restore the normal biometric recognition verification function of the terminal device. In this case, the terminal device may receive the biometric recognition verification information input by the user. After the user inputs corresponding biometric recognition verification information on the biometric recognition verification screen, the biometric recognition verification information may be acquired. At any moment after the terminal device starts timing and before the predetermined duration is reached, the user still cannot unlock the target object by using the biometric recognition verification information, that is, at this moment, the biometric recognition verification information or the verification mode corresponding to the biometric recognition verification information is still in a disabled state. 
     The step S 218  includes: determining that verification succeeds if the biometric recognition verification information matches preset first verification information. 
     In addition, there may be a plurality of processing manners different from the processing manner of the foregoing step S 204  to step S 212  and the processing manner of the foregoing step S 214  to step S 218 . The following further provides an optional implementation, which may specifically include the following step S 220  to step S 224 . 
     The step S 220  includes: disabling the biometric recognition module so that the biometric recognition module is unavailable for a preset first number of times if the touchscreen operation is the predetermined operation. 
     The first number of times may be set according to an actual situation, and is specifically, 5 times, 10 times, or the like. 
     In an implementation, if the disablement level of the biometric recognition module preset by the user in the terminal device is: disabled for a preset first number of times, when the terminal device acquires the touchscreen operation of the user and determines that the touchscreen operation is the predetermined operation, the terminal device may determine that the user wants to disable the biometric recognition module. In this case, the terminal device may perform processing of disabling the biometric recognition module, to prevent the biometric recognition module from acquiring the biometric recognition verification information. In this way, the user cannot pass verification by using the biometric recognition verification information. In addition, if the disablement level currently set in the terminal device is the disabled for a preset first number of times, the terminal device may stop using the biometric recognition module to perform verification processing. 
     In addition, in a case that the disablement level is the disabled for a preset first number of times, after the biometric recognition module has been disabled and unavailable for the preset first number of times, the terminal device may restore normal operation of the biometric recognition module, which may specifically include the following step S 222  and step S 224 . 
     The step S 222  includes: starting counting a number of times that the biometric recognition module is attempted to be used when it is determined that the acquired touchscreen operation is the predetermined operation, and acquiring biometric recognition verification information input by a user after the number of times reaches the preset first number of times. 
     In an implementation, the terminal device starts timing when a touchscreen operation performed by the user is received and it is determined that the touchscreen operation is the predetermined operation. After the predetermined duration is reached, the terminal device may automatically revoke the disablement of the biometric recognition verification information or a verification mode corresponding to the biometric recognition verification information, so as to restore the normal biometric recognition verification function of the terminal device. In this case, the terminal device may receive the biometric recognition verification information input by the user. After the user inputs corresponding biometric recognition verification information on the biometric recognition verification screen, the biometric recognition verification information may be acquired. At any moment after the terminal device starts timing and before the predetermined duration is reached, the user still cannot unlock the target object by using the biometric recognition verification information, that is, at this moment, the biometric recognition verification information or the verification mode corresponding to the biometric recognition verification information is still in a disabled state. 
     The step S 224  includes: determining that the verification succeeds if the biometric recognition verification information matches preset first verification information. 
     In addition, there may be a plurality of processing manners different from the processing manner of the foregoing step S 204  to step S 212 , the processing manner of the foregoing step S 214  to step S 218 , and the processing manner of the foregoing step S 220  to step S 224 . The following further provides an optional implementation, which may specifically include the following step S 226 . 
     The step S 226  includes: disabling a biometric recognition module and changing an authentication mode if the touchscreen operation is the predetermined operation. 
     The authentication mode may be a verification mode. The authentication mode may include an authentication mode based on biometric recognition, an authentication mode based on a gesture pattern, a character-based authentication mode, and the like. 
     In an implementation, if the disablement level of the biometric recognition module preset by the user in the terminal device is: changing authentication mode, and the terminal device stores therein a preset authentication mode to be changed to (for example, changing from the authentication mode based on biometric recognition to a character-based authentication mode), when the touchscreen operation of the user is acquired and it is determined that the touchscreen operation is the predetermined operation, the terminal device may determine that the user wants to disable the biometric recognition module. In this case, the terminal device may perform processing of disabling the biometric recognition module, to prevent the biometric recognition module from acquiring the biometric recognition verification information. In this way, the user cannot pass verification by using the biometric recognition verification information. In addition, if the disablement level currently set in the terminal device is the changing authentication mode, the terminal device may stop using the biometric recognition module and instead use the authentication mode preset by the user to verify the user. Based on the foregoing example, if the user undergoes verification by inputting characters, for a specific verification process, reference may be made to the foregoing step S 206  to step S 212 . Optionally, in the process of setting a disablement level, for the disablement level of changing authentication mode, the user may preset a verification password including characters, a gesture pattern, or the like. 
     In the foregoing case, if the user needs to continue using the biometric recognition module, an adjustment may be made through system settings of the terminal device. 
     In addition, there may be a plurality of processing manners different from the processing manner of the foregoing step S 204  to step S 212 , the processing manner of the foregoing step S 214  to step S 218 , the processing manner of the foregoing step S 220  to step S 224 , and the processing manner of step S 226 . The following further provides an optional implementation, which may specifically include the following step S 228 . 
     The step S 228  includes: deleting a locally pre-stored biometric feature corresponding to a biometric recognition module if the touchscreen operation is the predetermined operation. 
     The biometric feature may include biometric device verification information (that is, the first verification information), information related to the user, and the like. 
     In an implementation, if the disablement level of the biometric recognition module preset by the user in the terminal device is: deleting a biometric feature corresponding to a biometric recognition module, when the touchscreen operation of the user is acquired and it is determined that the touchscreen operation is the predetermined operation, the terminal device may determine that the user wants to delete a biometric feature corresponding to the biometric recognition module. In this case, the terminal device may delete a biometric feature of a specific user which is preset by the user or may delete all biometric features, so that there is no biometric feature pre-stored in the terminal device and therefore the biometric recognition module cannot be used. In this way, the user cannot pass verification by using the biometric recognition verification information, thereby ensuring the security of an account of the user. In the foregoing case, if the user needs to continue using the biometric recognition module, a biometric feature may be input again and saved. 
     It should be noted that, the processing manner of the foregoing step S 204  to step S 212 , the processing manner of the foregoing step S 214  to step S 218 , the processing manner of the foregoing step S 220  to step S 224 , the processing manner of step S 226 , and the processing manner of step S 228  are separately described hereinbefore. In a practical application, the terminal device may simultaneously perform two or more processing manners of the foregoing plurality of processing manners. For related processing processes, reference may be made to the foregoing description. Details thereof are not described herein again. 
     In addition, if it is determined through the determination process of the foregoing step S 202  that the touchscreen operation is not the predetermined operation, the processes of the following step S 230  and step S 232  may be performed. 
     The step S 230  includes: acquiring biometric recognition verification information input by a user if the touchscreen operation is not the predetermined operation. 
     The step S 232  includes: determining that the verification succeeds if the biometric recognition verification information acquired in the foregoing step S 230  matches preset first verification information. 
     It should be noted that, in the foregoing embodiment, to better describe a detailed processing process of security verification, the screen unlocking of the terminal device is used as an example. In a practical application, the method for security verification in sonic embodiments of the present disclosure is not limited to be applied to screen unlocking, but may be applied to biometric recognition unlocking for launching an application program, biometric recognition payment in a transaction process, and the like. For a specific processing process thereof, reference may be made to the foregoing related description. Details thereof are not described herein again. 
     In the method for security verification provided in some embodiments of the present disclosure, it is determined whether a received touchscreen operation is a predetermined operation, then corresponding verification processing is performed. That is, if the touchscreen operation is not the predetermined operation, biometric recognition verification information input by a user is acquired and the biometric recognition verification information is verified; if the touchscreen operation is the predetermined operation, verification processing corresponding to the predetermined operation is performed. In this way, a set predetermined touchscreen operation is used to control whether biometric recognition verification succeeds. For example, when a situation where the identity verification may be against the user&#39;s will is encountered, the user may use the predetermined touchscreen operation to make the biometric recognition verification for unlocking, payment or the like to fail, so that it is ensured that no leakage of file or data stored in a terminal device would occur, thereby improving the security of user information and property. 
     In addition, the predetermined operation is preset for disabling the biometric recognition module (the fingerprint capturing component shown in  FIG. 3 , or the like) currently used in the terminal device, so that the currently used biometric recognition verification information or a verification mode corresponding to the biometric recognition verification information is invalidated or disabled, to lock a. target object requiring biometric recognition verification. It is ensured that a leakage of file or data stored in a terminal device does not occur, thereby improving the security of user information and property.

In this way, a set predetermined touchscreen operation is used to control whether biometric recognition verification succeeds. For example, when a situation where the identity verification may be against the user&#39;s will is encountered, the user may use the predetermined touchscreen operation to make the biometric recognition verification for unlocking, payment or the like to fail, so that it is ensured that no leakage of file or data stored in a terminal device would occur, thereby improving the security of user information and property. 
     In addition, the predetermined operation is preset for disabling the biometric recognition module (the fingerprint capturing component shown in  FIG. 3 , or the like) currently used in the terminal device, so that the currently used biometric recognition verification information or a verification mode corresponding to the biometric recognition verification information is invalidated or disabled, to lock a target object requiring biometric recognition verification.
