[0059] It should be understood that, although the terms first, second, third, etc. may be used to describe various information in this article, these information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of this article, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein can be interpreted as "at the time of" or "when" or "in response to determination". Furthermore, as used in this article, the singular forms "one", "one" and "the" are intended to also include plural forms, unless there is an opposite indication in the context. It should be further understood that the terms "comprising" and "including" indicate that there are the described features, steps, operations, elements, components, projects, kinds, and / or groups, but do not exclude the existence, occurrence or addition of one or more other features, steps, operations, elements, components, projects, kinds, and / or groups. The terms "or", "and / or", "including at least one of the following" etc. used in this application can be interpreted as inclusive, or mean any one or any combination. For example, “comprising at least one of the following: A, B, C” means “any of the following: A; B; C; A and B; A and C; B and C; A and B and C”, and for another example, “A, B or C” or “A, B and / or C” means “any of the following: A; B; C; A and B; A and C; B and C; A and B and C”. An exception to this definition will only occur when a combination of elements, functions, steps or operations are inherently mutually exclusive in some manner.

[0060] It should be understood that, although the various steps in the flowchart in the embodiment of the present application are displayed in sequence according to the indication of the arrows, these steps are not necessarily performed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and it can be performed in other orders. Moreover, at least a portion of the steps in the figure may include a plurality of sub-steps or a plurality of stages, and these sub-steps or stages are not necessarily performed at the same time, but can be performed at different times, and their execution order is not necessarily performed in sequence, but can be performed in turn or alternately with other steps or at least a portion of the sub-steps or stages of other steps.

[0061] As used herein, the words "if" and "if" may be interpreted as "at the time of" or "when" or "in response to determining" or "in response to detecting", depending on the context. Similarly, the phrases "if it is determined" or "if (stated condition or event) is detected" may be interpreted as "when it is determined" or "in response to determining" or "when detecting (stated condition or event)" or "in response to detecting (stated condition or event)", depending on the context.

[0062] It should be noted that in this article, step codes such as S10 and S20 are used for the purpose of expressing the corresponding content more clearly and concisely, and do not constitute a substantial limitation on the sequence. When implementing the step, those skilled in the art may execute S20 first and then S10, etc., but these should all be within the scope of protection of this application.

[0063] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0064] In the subsequent description, the suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of the present application, and have no specific meanings. Therefore, "module", "component" or "unit" can be used in a mixed manner.

[0067] See also Figure 1 , which is a schematic diagram of the hardware structure of a smart terminal for implementing various embodiments of the present application, the smart terminal 100 may include: RF (Radio Frequency) unit 101, WiFi module 102, audio output unit 103, A / V (audio / video) input unit 104, sensor 105, display unit 106, user input unit 107, interface unit 108, memory 109, processor 110, and power supply 111 and other components. Those skilled in the art can understand that Figure 1 The structure of the smart terminal shown in the figure does not constitute a limitation on the smart terminal. The smart terminal may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0068] Combine the following Figure 1 A detailed introduction to each component of the smart terminal:

[0070] WiFi is a short-range wireless transmission technology. The smart terminal can help users send and receive emails, browse web pages, and access streaming media through the WiFi module 102. It provides users with wireless broadband Internet access. Figure 1 The WiFi module 102 is shown, but it is understandable that it is not a necessary component of the smart terminal and can be omitted as needed without changing the essence of the invention.

[0071] The audio output unit 103 can convert the audio data received by the RF unit 101 or the WiFi module 102 or stored in the memory 109 into an audio signal and output it as sound when the smart terminal 100 is in a call signal receiving mode, a call mode, a recording mode, a voice recognition mode, a broadcast receiving mode, etc. Moreover, the audio output unit 103 can also provide audio output related to a specific function performed by the smart terminal 100 (for example, a call signal receiving sound, a message receiving sound, etc.). The audio output unit 103 may include a speaker, a buzzer, etc.

[0072] The A / V input unit 104 is used to receive audio or video signals. The A / V input unit 104 may include a graphics processor (GPU) 1041 and a microphone 1042, and the graphics processor 1041 processes the image data of a static picture or video obtained by an image capture device (such as a camera) in a video capture mode or an image capture mode. The processed image frame can be displayed on the display unit 106. The image frame processed by the graphics processor 1041 can be stored in the memory 109 (or other storage medium) or sent via the radio frequency unit 101 or the WiFi module 102. The microphone 1042 can receive sound (audio data) via the microphone 1042 in a telephone call mode, a recording mode, a voice recognition mode, and other operating modes, and can process such sound into audio data. The processed audio (voice) data can be converted into a format output that can be sent to a mobile communication base station via the radio frequency unit 101 in the case of a telephone call mode. The microphone 1042 can implement various types of noise elimination (or suppression) algorithms to eliminate (or suppress) noise or interference generated in the process of receiving and sending audio signals.

[0073] The smart terminal 100 also includes at least one sensor 105, such as a light sensor, a motion sensor, and other sensors. Optionally, the light sensor includes an ambient light sensor and a proximity sensor. Optionally, the ambient light sensor can adjust the brightness of the display panel 1061 according to the brightness of the ambient light, and the proximity sensor can turn off the display panel 1061 and / or the backlight when the smart terminal 100 is moved to the ear. As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in all directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that identify 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), etc.; as for other sensors that can also be configured on the mobile phone, such as fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be repeated here.

[0074] The display unit 106 is used to display information input by the user or information provided to the user. The display unit 106 may include a display panel 1061, which may be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), or the like.

[0075] The user input unit 107 can be used to receive input digital or character information, and to generate key signal input related to the user settings and function control of the intelligent terminal. Optionally, the user input unit 107 may include a touch panel 1071 and other input devices 1072. The touch panel 1071, also known as a touch screen, can collect the user's touch operation on or near it (such as the user's operation on the touch panel 1071 or near the touch panel 1071 using any suitable object or accessory such as a finger, stylus, etc.), and drive the corresponding connection device according to a pre-set program. The touch panel 1071 may include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch orientation, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into the touch point coordinates, and then sends it to the processor 110, and can receive and execute commands sent by the processor 110. In addition, the touch panel 1071 can be implemented in various types such as resistive, capacitive, infrared, and surface acoustic waves. In addition to the touch panel 1071, the user input unit 107 may further include other input devices 1072. Optionally, the other input devices 1072 may include, but are not limited to, one or more of a physical keyboard, a function key (such as a volume control key, a switch key, etc.), a trackball, a mouse, a joystick, etc., which are not specifically limited here.

[0076] Optionally, the touch panel 1071 may cover the display panel 1061. When the touch panel 1071 detects a touch operation on or near it, it transmits the information to the processor 110 to determine the type of touch event. Then, the processor 110 provides corresponding visual output on the display panel 1061 according to the type of touch event. Figure 1 In the figure, the touch panel 1071 and the display panel 1061 are used as two independent components to realize the input and output functions of the smart terminal. However, in some embodiments, the touch panel 1071 and the display panel 1061 can be integrated to realize the input and output functions of the smart terminal, which is not limited here.

[0078] The memory 109 can be used to store software programs and various data. The memory 109 can mainly include a program storage area and a data storage area. Optionally, the program storage area can store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc.; the data storage area can store data created according to the use of the mobile phone (such as audio data, a phone book, etc.), etc. In addition, the memory 109 can include a high-speed random access memory, and can also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage devices.

[0079] The processor 110 is the control center of the smart terminal. It uses various interfaces and lines to connect various parts of the entire smart terminal. It executes various functions of the smart terminal and processes data by running or executing software programs and / or modules stored in the memory 109, and calling data stored in the memory 109, so as to monitor the smart terminal as a whole. The processor 110 may include one or more processing units; preferably, the processor 110 may integrate an application processor and a modem processor. Optionally, the application processor mainly processes the operating system, user interface, and application programs, and the modem processor mainly processes wireless communications. It is understandable that the above-mentioned modem processor may not be integrated into the processor 110.

[0080] The intelligent terminal 100 may also include a power supply 111 (such as a battery) for supplying power to various components. Preferably, the power supply 111 may be logically connected to the processor 110 through a power management system, thereby managing functions such as charging, discharging, and power consumption through the power management system.

[0081] although Figure 1 Not shown, the smart terminal 100 may also include a Bluetooth module, etc., which will not be described in detail here.

[0082] To facilitate understanding of the embodiments of the present application, the communication network system on which the smart terminal of the present application is based is described below.

[0083] See also Figure 2 , Figure 2 A communication network system architecture diagram is provided for an embodiment of the present application, wherein the communication network system is an LTE system of universal mobile communication technology, and the LTE system includes a UE (User Equipment) 201, an E-UTRAN (Evolved UMTS Terrestrial Radio Access Network) 202, an EPC (Evolved Packet Core) 203 and an operator's IP service 204, which are connected in sequence for communication.

[0084] Optionally, UE201 may be the above-mentioned terminal 100, which will not be described in detail here.

[0085] E-UTRAN 202 includes eNodeB 2021 and other eNodeBs 2022 , etc. Optionally, eNodeB 2021 may be connected to other eNodeBs 2022 via a backhaul (eg, an X2 interface), and eNodeB 2021 is connected to EPC 203 , and eNodeB 2021 may provide UE 201 with access to EPC 203 .

[0086] EPC203 may include MME (Mobility Management Entity) 2031, HSS (Home Subscriber Server) 2032, other MMEs 2033, SGW (Serving Gate Way) 2034, PGW (PDN Gate Way) 2035 and PCRF (Policy and Charging Rules Function) 2036, etc. Optionally, MME 2031 is a control node that processes signaling between UE 201 and EPC 203, and provides bearer and connection management. HSS 2032 is used to provide some registers to manage functions such as home location register (not shown in the figure), and store some user-specific information such as service features and data rates. All user data can be sent through SGW2034, PGW2035 can provide IP address allocation and other functions for UE 201, PCRF2036 is the policy and charging control policy decision point for service data flow and IP bearer resources, which selects and provides available policy and charging control decisions for the policy and charging execution function unit (not shown in the figure).

[0087] The IP service 204 may include the Internet, an intranet, an IMS (IP Multimedia Subsystem) or other IP services.

[0088] Although the above introduction takes the LTE system as an example, those skilled in the art should know that the present application is not only applicable to the LTE system, but also to other wireless communication systems, such as GSM, CDMA2000, WCDMA, TD-SCDMA, 5G and future new network systems (such as 6G), etc., without limitation here.

[0089] Based on the above-mentioned smart terminal hardware structure and communication network system, various embodiments of the present application are proposed.

[0090] In some embodiments, in order to improve the security of the smart terminal, the smart terminal sets a series of security verification methods, including but not limited to password verification or biometric verification, etc. When a user uses the smart terminal to perform a specific operation, a security verification must be performed first. Only when the security verification is passed can the specific operation be performed to prevent non-owners from using the smart terminal.

[0091] Optionally, the user in this application is any user who uses a smart terminal. The owner in this application is the user to whom the smart terminal belongs.

[0092] Figure 3 A schematic diagram of an application scenario of a related control method.

[0093] See also Figure 3 , the user operates the smart terminal to perform a specific operation, and the smart terminal displays a security verification interface. If the user enters the security verification information correctly, the specific operation can be performed.

[0094] However, in actual applications, even if the user has not been authenticated or has failed the authentication, the user can still perform some operations, such as long pressing the power button to shut down the device, removing the Subscriber Identity Module (SIM card), or turning off the communication function.

[0095] Combined with the scenario example, if the smart terminal is lost, a non-owner may shut down the device, remove the user identification module, or turn off the communication function, causing the owner to be unable to contact the smart terminal, thereby posing the risk of the owner's privacy information being exposed.

[0096] Optionally, closing the communication function can be achieved by pulling down the status bar or the shortcut center. The pulled-down status bar or the shortcut center can still be used without security verification when the smart terminal is locked.

[0097] In order to solve the above problems, an embodiment of the present application provides a control method, in which the smart terminal controls the execution of the target operation through the current unlock state and / or the current security policy. Compared with directly executing the target operation, restriction conditions can be added to improve the security of the smart terminal.

[0098] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in one or more embodiments of this specification are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with relevant laws, regulations and standards, and corresponding operation entrances shall be provided for users to choose to authorize or refuse.

[0099] The technical solutions shown in the present application are described in detail below through specific embodiments. Optionally, the following embodiments may exist alone or in combination with each other, and the same or similar contents will not be described repeatedly in different embodiments.

[0105] Optionally, the currently received operation does not distinguish whether it is executed by the machine owner or a non-machine owner.

[0106] Combined with the scenario example, the user long presses the power button of the smart terminal, corresponding to the target operation of shutting down the terminal, triggering the target operation instruction. The user inserts the card pin into the pinhole of the user identification module slot, corresponding to the target operation of removing the user identification module, triggering the target operation instruction. The user selects at least one shortcut icon of the communication function in the drop-down status box or shortcut center, corresponding to the target operation of shutting down the communication function, triggering the target operation instruction.

[0107] Optionally, the communication function includes but is not limited to at least one of the following: Bluetooth, cellular data, WIFI, airplane mode, positioning function, bedtime mode, or do not disturb mode, etc.

[0108] Figure 5 A schematic diagram of shutting down the communication function provided in an embodiment of the present application.

[0109] See also Figure 5 , open the drop-down status box, select an icon related to the communication function, and operate the icon to turn off the communication function.

[0110] It should be noted that the present application does not limit the specific type of target operation, and any operation that affects the security of the smart terminal is a target operation.

[0111] S20: Determine a current unlock state of the smart terminal according to the target operation instruction, where the current unlock state includes an unlocked state or an unlocked state.

[0112] Optionally, the current unlock state is used to restrict execution of the target operation.

[0113] Combined with the scenario example, the smart terminal enters the unlocked state when the screen is off or after a preset time after the screen is off. After entering the unlocked state, the user needs to perform security verification to unlock the screen. If the security verification passes, the smart terminal enters the unlocked state. The current unlocked state is the unlocked state. Compared with the unlocked state, the smart terminal can perform fewer operations.

[0114] Optionally, when determining the current unlock state, the target operation is not performed to avoid security issues caused by directly performing the target operation.

[0115] Optionally, the current unlocking status is determined through a system log of the smart terminal.

[0116] Optionally, in combination with the scenario example, each time the unlock state of the smart terminal changes, it is recorded in the system log, and the current unlock state is determined based on the latest unlock state change record in the system log. Optionally, the latest unlock state change record reflects the unlock state of the smart terminal after the last unlock state change.

[0117] S30: Determine the current security policy of the smart terminal.

[0118] Optionally, the current security policy is used to determine whether the current target operation can be directly executed, and the current security policy is used to restrict the execution of the target operation.

[0119] Optionally, the security policy can be changed by the owner through a smart terminal, other devices, or a service website.

[0120] Optionally, only the owner of the smart terminal and the user designated by the owner have the authority to change the security policy.

[0121] Combined with the scenario example, if the owner can operate the smart terminal, the security policy can be changed through the smart terminal itself. If the owner is away from the smart terminal and cannot directly operate the smart terminal, the security policy can be changed by sending instructions to the smart terminal through other devices or service websites.

[0122] Optionally, the owner needs to undergo an independent security verification before changing the security policy. If the verification passes, the security policy can be changed, thereby further improving the security of the smart terminal.

[0123] Optionally, a corresponding current security policy is set for each target operation, that is, the current security policies for each target operation are independent of each other.

[0124] S40: Execute the target operation according to the current unlocking state and / or the current security policy.

[0125] Optionally, dual restrictions are imposed on the execution of the target operation through the current unlocking state and the current security policy to improve the security of executing the target operation.

[0126] Optionally, if both the current unlock state and the current security policy support the execution of the target operation, the target operation is executed. If either the current unlock state or the current security policy does not support the execution of the target operation, the target operation is not executed.

[0127] Optionally, through double restrictions, the security of smart terminals can be effectively improved.

[0128] Combined with the scenario example, take the target operation as shutdown as an example. If the target operation is supported, the power is shut down. If the target operation is not supported, the shutdown function is paused, and long pressing the power button does not execute shutdown.

[0129] The embodiment of the present application provides a control method, S10: receiving a target operation instruction, the target operation instruction is used to instruct the execution of at least one of the following target operations: shutting down, removing a user identification module, or shutting down a communication function; S20: determining the current unlocking state of the smart terminal according to the target operation instruction, the current unlocking state includes an unlocked state or an unlocked state; S30: determining the current security policy of the smart terminal; S40: executing the target operation according to the current unlocking state and / or the current security policy. In the above scheme, the smart terminal controls the execution of the target operation through the current unlocking state and / or the current security policy, and compared with directly executing the target operation, it can add restriction conditions, thereby improving the security of the smart terminal.

[0130] Second embodiment

[0131] exist Figure 4 Based on the embodiment shown below, combined with Figure 6 , the detailed process of the control method is explained.

[0132] Figure 6 A flow chart of step S40 of a control method provided in an embodiment of the present application. Figure 6 , in the method S40 may include:

[0133] S201. Determine whether to perform security verification according to the current unlocking state and / or the current security policy.

[0134] Optionally, security verification includes but is not limited to at least one of the following: password verification, or biometric verification, etc.

[0135] Optionally, the security verification is distinguished from the verification of unlocking the smart terminal to improve the security of the smart terminal.

[0136] Combined with the scenario example, for example, the verification password for unlocking the smart terminal is 666666, and the verification password for security verification is 555555. The two passwords are different from each other to achieve dual authentication, thereby improving the security of the smart terminal.

[0137] Optionally, the security level of the smart terminal is determined according to the current unlocking state and / or the current security policy. A high security level indicates that the smart terminal has strict security requirements, and security verification needs to be performed to meet the security requirements of the smart terminal.

[0138] Optionally, whether to perform security verification can be determined by the following method: if the current security policy is the first policy, it is determined not to perform the security verification, and the first policy is: in the unlocked state or the unlocked state, the security verification is not performed; if the current security policy is not the first policy, it is determined whether to perform security verification based on the current unlocked state and the current security policy.

[0139] Optionally, the first policy is a policy with the most relaxed security requirements. Under the first policy, security verification does not need to be performed on the smart terminal in an unlocked state or an unlocked state.

[0140] Combined with the scenario example, if the current security policy is the first policy, there is no need to consider the current unlocking state and the target operation can be performed directly.

[0141] Optionally, whether to perform security verification can be determined by the following method: if the current unlocked state is the unlocked state, and the current security policy is the second policy, then it is determined not to perform the security verification, and the second policy is: in the un-unlocked state, the security verification is performed; if the current unlocked state is the unlocked state, and the current security policy is the third policy, then it is determined to perform the security verification, and the third policy is: in the unlocked state or the un-unlocked state, the security verification is performed; if the current unlocked state is the un-unlocked state, and the current security policy is the second policy, then it is determined to perform the security verification; if the current unlocked state is the un-unlocked state, and the current security policy is the third policy, then it is determined to perform the security verification.

[0142] Optionally, the second strategy is to perform security verification only in the unlocked state, and the security requirement corresponding to the second strategy is stricter than that of the first strategy. The third strategy is to perform security verification in both the unlocked state and the unlocked state, and the security requirement corresponding to the third strategy is the strictest.

[0143] Figure 7 A schematic diagram of determining whether to perform security verification is provided in an embodiment of the present application.

[0144] See also Figure 7 , under the premise that the current security policy is not the first policy, the current unlocking state is discussed separately. If the smart terminal is in the unlocking state, it is further determined whether the current security policy is the second policy or the third policy. If the current security policy is the second policy, security verification is not performed. If the current security policy is the third policy, security verification is performed. If the smart terminal is not unlocked, the current security policy is the second policy or the third policy and security verification is performed.

[0145] In this feasible implementation, by combining the current unlocking status and the current security policy, it is possible to comprehensively determine whether to perform security verification from multiple dimensions, thereby improving the accuracy of the judgment.

[0146] Optionally, whether to perform security verification can be determined by the following method: determining whether the security option corresponding to the target operation is in an on state; if so, determining whether to perform security verification based on the current unlock state and / or the current security policy.

[0147] Optionally, the security option corresponding to each target operation can be modified independently. For example, the owner sets the security option corresponding to shutdown to an on state, and sets the security option for removing the subscriber identity module to a off state.

[0148] Optionally, the security option being in an on state indicates that the judgment on whether to perform security verification is turned on, and the security option being in an off state indicates that the judgment on whether to perform security verification is not made.

[0149] Combined with the scenario example, taking the target operation as shutdown as an example, if the security option is turned on, it is determined whether to perform security verification. If the security option is turned off, that is, the user setting allows free shutdown, it is not determined whether to perform security verification, and the shutdown is performed directly.

[0150] In this feasible implementation, a modification scheme for security options is provided, which can increase the verification level of security verification. Through multi-level security verification, the security of the smart terminal can be effectively improved.

[0151] Optionally, the control method further includes: receiving a target option control indication, wherein the target option control indication includes at least one of the following indication operations: shutting down, removing a user identification module, or shutting down a communication function; and switching a security option corresponding to the indication operation to an on state.

[0152] Optionally, the communication function includes but is not limited to at least one of the following: Bluetooth, cellular data, WIFI, airplane mode, positioning function, bedtime mode, or do not disturb mode, etc.

[0153] Optionally, the target option control indication may be generated by the machine owner operating the smart terminal, or may be generated by the machine owner through other devices or a service website and sent to the smart terminal.

[0154] In combination with the scenario example, the smart terminal is lost, and the owner generates and sends it to the smart terminal through other devices or service websites, so that non-owners cannot perform the target operation.

[0155] In this feasible implementation, whether the smart terminal performs a security operation can be controlled at any time through the target option control indication, thereby improving the security of the smart terminal.

[0156] If yes, execute S202.

[0157] If not, execute S203.

[0158] S202, perform security verification to obtain a verification result, wherein the verification result includes verification passed or verification failed. If the verification result is verification passed, perform the target operation.

[0159] Optionally, if the verification is successful, it means that the user has the authority to perform the target operation, and the target operation is performed. If the verification is not successful, it means that the user does not have the authority to perform the target operation, and the target operation is not performed.

[0160] S203: Execute the target operation.

[0161] Optionally, if it is determined according to S201 that security verification is not to be performed, it means that the smart terminal does not have strict security requirements, and thus security verification does not need to be performed, and the target operation can be performed directly.

[0162] Combined with the scenario example, for smart terminals that do not store important information, strict security requirements are not required, and the owner can set it not to perform security verification. For smart terminals that need to frequently replace the user identification module, if verification is performed every time the user identification module is taken out, it will lead to low efficiency in replacing the user identification module. The owner can set it not to perform security verification.

[0163] Third embodiment

[0164] Based on any of the above embodiments, Figure 8 , which explains how to perform the shutdown operation.

[0165] Figure 8 A schematic diagram of performing a shutdown operation provided in an embodiment of the present application. Figure 8, the user triggers the smart terminal to shut down by clicking an icon or long pressing the power button. If the smart terminal has set security verification, the security verification is performed to obtain the security verification result. If the security verification result is verification passed, the shutdown is executed. If security verification is not set, the "Add verification" prompt is displayed on the interface of the smart terminal. If the user chooses to add, the shutdown is executed after the security verification information is added.

[0166] Optionally, a threshold of the number of times the security verification is repeatedly executed is set, and when the number of times the security verification is repeatedly executed is greater than or equal to the threshold, the security verification and the shutdown are stopped.

[0167] Optionally, the path for performing operations such as removing the user identification module or shutting down the communication function is the same as the path for performing the shutdown operation, and this application will not go into details.

[0168] Optionally, the target operation at least includes removing a user identification module, and the operation of removing the user identification module can be performed by the following method: sending a first drive signal to a first drive device of the smart terminal to switch the drive device to an unlocked state, and the first drive device is used to lock the user identification module; or sending a second drive signal to a second drive device of the smart terminal to cause the second drive device to pop out the user identification module from the smart terminal.

[0169] Figure 9a A schematic diagram of a user identification module slot provided in an embodiment of the present application.

[0170] See also Figure 9a , a user identification module can be installed on the user identification card slot 92. After the user identification card slot 92 with the user identification module installed is inserted into the smart terminal, the smart terminal can read the information of the user identification module. When the user identification card slot 92 is inserted into the smart terminal, the card pin 93 can be inserted into the opening of the user identification card slot 92 to make the user identification card slot 92 pop out from the smart terminal. If the first drive device 91 is in a locked state, that is, the first drive device 91 is inserted into the user identification card slot 92, the card pin 93 cannot be inserted to the bottom at this time, and the user identification card slot 92 cannot pop out from the smart terminal, thereby improving the security of the user identification card slot. When executing the target operation of removing the user identification module, a first drive signal is sent to the first drive device 91, and the first drive signal is used to control the first drive device 91 to separate from the user identification card slot 92. At this time, the card pin 93 can be inserted to the bottom, so that the user identification card slot can be removed through the card pin 93, and then the user identification module installed in the user identification card slot 92 is removed.

[0171] Figure 9b A schematic diagram of a user identification module slot provided in an embodiment of the present application.

[0172] See also Figure 9b The user identification card slot 92 includes a limiting hole 94, and the first driving device can be configured to be inserted into the limiting hole 94. After the first driving device is inserted into the limiting hole 94, the user identification card slot 92 is locked in the smart terminal. Even if the card pin is inserted into the user identification card slot 92, the user identification card slot 92 cannot be removed from the smart terminal.

[0173] Optionally, the user identification card slot may be designed to include no opening and cannot be removed by a card pin. The second driving device is an elastic member.

[0174] Optionally, the user identification card slot is connected to the smart terminal via an elastic member, and the user triggers the removal of the user identification module on the smart terminal interface. After the security verification is passed, the smart terminal drives the elastic member to pop out the user identification card slot via a second drive signal, thereby allowing the user to remove the user identification module from the user identification card slot.

[0175] In this feasible implementation, the user identification module is removed by controlling the driving signal, so that a non-user can avoid freely removing the user identification module, thereby improving the security of the smart terminal.

[0176] Fourth embodiment

[0177] Based on any of the above embodiments, Fig.10 , explain the instructions for executing the target function.

[0178] Fig.10 A flowchart of an execution target function instruction provided in an embodiment of the present application. Fig.10 , which may include:

[0179] S50: Receive a target function indication, where the target function indication is used to indicate to enable at least one of the following target functions: automatic photo taking, automatic video recording, automatic answering of calls, or automatic uploading of positioning information.

[0180] Combined with the scenario example, for the scenario where the smart terminal has been lost or is not with the owner, by adding security verification to shut down, remove the user identification module, or turn off the communication function, the smart terminal can still communicate. On this basis, the owner sends the target function instruction to the smart terminal through other devices or service websites to obtain the information of the smart terminal.

[0181] Optionally, combined with the scenario example, by instructing automatic photo taking, automatic video recording, and automatic call answering, the remote owner can obtain the environmental information of the location of the smart terminal, so that the owner can find the smart terminal. By instructing automatic upload of positioning information, the remote owner can obtain the positioning information of the location of the smart terminal.

[0182] S60: Activate the target function according to the target function indication.

[0183] Optionally, after the target function is enabled, the target function may be executed after being triggered.

[0184] Optionally, the owner can set the triggering conditions of the target function.

[0185] Optionally, the target function may be executed periodically or triggered by a specific action.

[0186] In combination with the scenario example, the specific action may be lighting up the screen. When the smart terminal detects that the screen is lit up, the target function is triggered to execute.

[0187] Based on the above implementation modes, through the target function, the remote owner can obtain detailed environmental information and / or positioning information of the smart terminal, thereby effectively helping the owner to retrieve the smart terminal and improving the security of the smart terminal.

[0188] Optionally, the target function indication also includes target address information or a target number; the method also includes: executing the target function, obtaining a target result, and sending the target result to the target address information; or, receiving a target call request, making a call according to the target call request, and the target call request includes the target number.

[0189] Optionally, the target address information is the address information set by the owner, and the target number is the number set by the owner.

[0190] Optionally, the target result may be an image obtained by taking a photo, a video obtained by recording a video, or positioning information, etc.

[0191] Combined with the scenario example, the owner remotely sends the target address information or target number to the smart terminal, and the smart terminal can automatically send the target result or automatically call according to the target address information or target number. For example, if the target number is 333333, the smart terminal will directly accept the call when it receives the number 333333, without the user clicking to confirm.

[0192] In this feasible implementation, by automatically sending the target result to the target address information, the owner can accurately obtain the target result, thereby effectively helping the owner to find the smart terminal and improving the security of the smart terminal. By automatically answering the target number, the owner can talk to the user currently using the smart terminal at any time through other devices, thereby effectively helping the owner to find the smart terminal and improving the security of the smart terminal.
