Description

Method for unlocking SIM card, electronic equipment and storage medium

Technical Field

The present disclosure relates to the field of terminal technologies, and in particular, to a method for unlocking a SIM card, an electronic device, and a storage medium.

Background

With the popularity of wireless networks, users pay more and more attention to the quality of wireless communication services, and wireless data services are closely related to wireless data terminals. In recent years, data services by wireless data terminals have become more and more popular. But this also presents a new problem in that the user may open the PIN code (Personal Identification Number) of the SIM card, i.e. the personal identification code of the SIM card, to protect his SIM card from others, so that the user enters the PIN code each time the wireless data terminal is initialized. At this time, not only is the user inconvenienced, but also if the user erroneously inputs the PIN code, there is a risk that the SIM card is locked.

The mobile phone becomes an indispensable portable communication tool in real life, brings convenience to the life of people, and brings some trouble and loss if the operation is improper. Most of the information, data information and the like about the mobile phone owner and related personnel are mainly stored in the common mobile phone, and once the information, the data information and the like are lost, the risk of data leakage can occur, so that certain spirit and property loss are brought to the life of people. The PIN code of the mobile phone is a safety measure for the SIM card, so that the SIM card is prevented from being stolen by others, and if the PIN code is started, 4-8 digits of the PIN code are input to unlock the SIM card after each start. Although the risk of data leakage after the mobile phone is lost can be reduced by opening the PIN code, great inconvenience is brought to people in daily use.

Disclosure of Invention

In view of the above, the present application provides an optimized method and apparatus for unlocking a SIM card.

In a first aspect, the present application provides a method for unlocking a SIM card in an electronic device, where the method includes:

when the SIM card is started (for example, when the SIM card is powered on), if the SIM card is provided with a PIN code and is provided with a password-free input mode (after the SIM card is provided with the mode, the situation that a user does not manually input the PIN code to unlock the SIM card when unlocking the SIM card is enabled, for example, the electronic device can automatically fill the stored PIN code into a password frame for inputting the PIN code or automatically send the stored PIN code to a module corresponding to the SIM card to unlock the SIM card) is adopted, the electronic device determines to unlock the SIM card by adopting one of a first mode and a second mode according to first information, wherein the first information is related to the state change of the SIM card and/or the state change of the electronic device, and the first mode is a password-free input mode, and the second mode is a mode that the user manually inputs the PIN code.

After the secret-free input mode is set for the SIM card (or understood as enabling or starting the secret-free input mode), the secret-free input mode is enabled to unlock the SIM card, but the secret-free input mode is not necessarily adopted to unlock the SIM card every time as long as the mode is set. In the above embodiment, whether to unlock the SIM card by adopting a password-free input mode or a PIN code manual input mode may be determined according to the state change of the SIM card and/or the state change of the electronic device, and some restrictions are imposed on the enablement of the password-free input mode of the SIM card in which the password-free input mode is set, so that it may be avoided that the security risk is brought by directly enabling the password-free input mode to unlock the SIM card without performing risk assessment in the case that the state of the SIM card and/or the electronic device is abnormal or unsafe.

In one implementation manner, after one of the first manner and the second manner is adopted to unlock the SIM card successfully, a startup password input interface is displayed, a startup password input by a user is received, and after the startup password passes verification, the electronic device displays a main interface after successful startup.

In one implementation, the determining, by the electronic device, to unlock the SIM card in one of the first manner and the second manner according to the first information includes: determining the current risk according to the first information, and unlocking the SIM card in a first mode if the current risk is the first risk; and if the current risk is a second risk, unlocking the SIM card in a second mode, wherein the first risk is lower than the second risk.

In one implementation, both the first risk and the second risk are levels of risk, e.g., the first risk is low risk or no risk, and the second risk is high risk or medium risk.

In another implementation, the first risk and the second risk are both risk values, e.g., the first risk is a first value and the second risk is a second value, wherein the first value is lower than the second value. Further, the first value is less than a preset risk value, and the second value may be greater than or equal to the preset risk value.

In one implementation, when a SIM card is started, judging whether the SIM card needs to input a PIN code to unlock the SIM card; if it is determined that the SIM card needs a PIN code to be unlocked, determining whether the SIM card has opened a password-free input mode for the SIM card (it can be understood that whether the user has previously set the password-free input mode for the SIM card); if the password-free input mode is determined to be unlocked, the electronic equipment calculates a risk value according to the wind control factor (the wind control factor can be determined through the state change of the SIM card detected by the wind control component (which can be a software module and/or a hardware element on the electronic equipment) and/or the state change of the electronic equipment), and judges whether the risk value is smaller than a preset risk value or not; if the risk value is smaller than the preset risk value, automatically acquiring a stored PIN code, and sending the stored PIN code to the SIM card to unlock the SIM card; if the risk value is determined to be greater than or equal to the preset risk value, displaying a password input interface, acquiring a PIN code manually input by a user on the password input interface, and sending the manually input PIN code to the SIM card to unlock the SIM card. According to the method, the SIM card is unlocked by automatically inputting the PIN code when the calculated risk value is smaller (the risk value is smaller than the preset risk value), the problem that the user cannot conveniently unlock the SIM card by manually inputting the PIN code every time is solved, and meanwhile, when the calculated risk value is larger (the risk value is not smaller than the preset risk value), the password input interface is displayed for the user to manually input the PIN code to unlock the SIM card, so that the safety of SIM card data is improved.

The various embodiments disclosed herein may be applied to an electronic device 100 (referring to fig. 1) capable of configuring a subscriber identity (subscriber identification module, SIM) card. The SIM card is a plug-in SIM module, which refers to a conventional SIM module or a SIM module chip. Such SIM modules require the user to go to or sign-on through the operator's on-line lobby and insert into the physical card slot (otherwise known as the SIM module interface) of the electronic device 100 after activation. It will be appreciated that the SIM card, which may also be referred to as a phone card, a smart card, etc., is actually a smart card containing a large-scale integrated circuit, and is mainly used to register important data and information of a user, such as information of a digital mobile phone client, an encrypted key, a phone book of the user, etc., for authenticating the identity of the client in the global system for mobile communications (Global System for Mobile Communication, GSM) network, and encrypting voice information when the client is talking.

In addition, the SIM card can be pulled out from the physical card slot.

The electronic device 100 according to the embodiments provided herein may refer to a device capable of installing and connecting to a mobile communication network through a SIM card and providing voice and/or data connectivity to a user. The electronic device 100 may communicate with one or more core networks via a radio access network (Radio Access Network, RAN). The electronic device 100 may be a portable electronic device 100 that includes functionality such as a personal digital assistant and/or a music player, such as a cell phone, tablet computer, wearable device with wireless communication functionality (e.g., a smart watch), and so forth. Exemplary embodiments of the portable electronic device 100 include, but are not limited to, a portable electronic device 100 that hosts or otherwise operates a system. The portable electronic device 100 described above may also be other portable electronic devices 100, such as a laptop computer (laptop) or the like having a touch-sensitive surface (e.g., a touch panel).

The personal identification password PIN code (Personal Identification Number) related to the embodiment provided by the application is a secret identification code for protecting the SIM card from misuse, and PIN code verification is a security measure for protecting the SIM card. If the PIN verification function of the SIM card is enabled, the electronic device 100 needs to perform PIN verification on the SIM card on the electronic device 100 after power-on or when the SIM card is inserted. If the wrong PIN code is entered multiple times, the electronic device 100 may require entry of an unlock code (PIN Unlocking Key, PUK) code for the PIN code. The PUK code consists of 8 digits, which cannot be changed by the user. When the mobile phone PIN code is locked and prompts to input the PUK code, the PUK code needs to be acquired from an operator to which the SIM card belongs, and the PIN code is unlocked after the PUK code is input. If the wrong PUK code is input for many times, the SIM card can start a self-destruction program, so that the SIM card is invalid and can only be replaced again. Therefore, setting the PIN code to lock the SIM card can reduce the risk of data leakage after the electronic device 100 is lost, but also brings the risk of improper operation to the user, which causes great inconvenience.

In addition, in the embodiment of the present application, the SIM card supported by the electronic device 100 may be any one of a global system for mobile communications (global system for mobile communication, GSM) standard, universal mobile telecommunications system (universal mobile telecommunications system, UMTS) standard, time division-synchronization code division multiple access (TD-SCDMA) standard, long term evolution (long term evolution, LTE) standard, code division multiple access (code division multiple access, CDMA) standard, and the like. The system supported by the SIM card in the electronic device 100 is not particularly limited in this embodiment.

For convenience of description, the following embodiments will take the example that the electronic device 100 supports two SIM cards as an example, and the embodiments of the present application will be described in detail.

For example, SIM module interface 1 may be used to connect SIM card 1 (SIM module 1), and SIM module interface 2 may be used to connect SIM card 2 (SIM module 2). The electronic device 100 also includes modems (modem) 0 and modem 1, and a smart card interface (smart card interface, SCI). Software located at the upper layers of the hardware can control the connection relation between different modems and different SIM module interfaces through SCI according to the selection of a user. Under the condition that the two SIM module interfaces are connected with the SIM cards, the electronic equipment 100 can be connected with the cellular mobile network through each SIM card and the modem connected with the SIM card so as to perform data interaction, realize the functions of communication, data communication and the like, and can realize the double-card double-standby function.

The electronic device 100 in the embodiment of the present application may be a device capable of connecting at least two SIM cards, for example. For example, the electronic device 100 may be a mobile phone, a smart bracelet, a smart watch, a tablet computer, etc., and the specific form of the electronic device 100 is not particularly limited in this embodiment.

The methods in the following embodiments may be implemented in the electronic device 100 having the above-described hardware structure.

The method for unlocking the SIM card provided by the embodiment of the present application may be applied to the electronic device 100 supporting two SIM cards. In the following embodiment, the electronic device 100 is taken as a mobile phone, and the structural composition of the electronic device 100 is described as an example shown in fig. 2. In the following embodiments, the SIM module interface 1 is a first SIM module interface 195 in the present application, the SIM module interface 2 is a second SIM module interface 196 in the present application, the SIM card 1 is a first SIM card in the present application, and the SIM card 2 is a second SIM card in the present application.

In some embodiments of the present application, if the state of the SIM card in the handset changes, the handset typically requires card setup.

The mobile phone can determine that the state of the SIM card in the mobile phone is changed when any one of the following conditions is detected: the SIM module interface (such as SIM module interface 1 or SIM module interface 2) changes from a state in which the SIM card is not connected to a state in which the SIM card is connected (or the SIM card is inserted into the SIM module interface); the SIM module interface is changed from a state of being connected with the SIM card to a state of not being connected with the SIM card (or the SIM card is pulled out from the SIM module interface, namely the SIM card is disconnected); the SIM card is changed from the working state to the non-working state (namely, the SIM card is not working after the mobile phone is powered off); the SIM module interface 1 changes from a state in which the SIM card 1 is connected to a state in which the SIM card 1 is not connected, to a state in which the SIM card 2 is connected, and so on.

For example, after the user performs the insertion operation or the extraction operation on the SIM card, the mobile phone may determine that the state of the SIM card in the mobile phone is changed.

For example, in the case that a certain SIM module interface (such as the SIM module interface 1) is not connected to the SIM card, after the user inserts the SIM card 1 into the SIM module interface 1, the mobile phone detects that the state of the SIM module interface 1 is changed from the state of the unconnected SIM card to the state of the connected SIM card, and at this time, the mobile phone can determine that the state of the SIM card in the mobile phone is changed.

For another example, when the SIM card 1 is connected to the SIM module interface 1, after the user pulls out the SIM card 1 from the SIM module interface 1, the mobile phone detects that the SIM module interface 1 is changed from the state where the SIM card is connected to the state where the SIM card is not connected, and at this time, the mobile phone can determine that the state of the SIM card in the mobile phone is changed.

Also, for example, in the case that the SIM module interface (e.g., SIM module interface 1 or SIM module interface 2) is connected to the SIM card, if the mobile phone is in the off state, the SIM card is changed from the operating state to the inactive state, and at this time, the mobile phone can determine that the state of the SIM card in the mobile phone is changed.

The embodiment provided by the application relates to a method for unlocking a SIM card after decryption and locking, which can calculate a risk value of leaking data of electronic equipment 100 according to a plurality of wind control factors obtained by the electronic equipment 100 in the process of using the SIM card, and determine a password input mode of the SIM card after decryption and locking according to the height of the risk value. The password input mode of the SIM card after decryption and locking at least comprises automatic filling of PIN codes, manual input of PIN codes by a user and the like. Specifically, the following describes the electronic device 100 as a mobile phone with a touch screen, and first, the setting interface 10 for locking the SIM card is shown in fig. 3.

Specifically, the setting interface 10 shown in fig. 3 includes: a SIM card selection control 101, a first switch control 102, and a password modification control 103.

Wherein: the SIM card selection control 101 is used to select the SIM card to be locked. Specifically, SIM card selection control 101 displays two options, card 1 and card 2. If the user operation of the user on the card 1 option is received, responding to the user operation, and determining to lock the SIM card corresponding to the card 1; if the user operation of the user on the option of the card 2 is received, the corresponding SIM card of the card 2 is determined to be locked in response to the user operation.

The first switch control 102 may be used to turn on/off the SIM card locking function. Specifically, the first switch control 102 has two display states, an "ON" state and an "OFF" state. When the first switch control 102 is displayed in the "ON" state, if a user operation of the first switch control 102 is received, the SIM card locking function is turned OFF in response to the user operation, and the first switch control 102 is switched from the display "ON" state to the display "OFF" state. When the first switch control 102 is displayed in the "OFF" state, if a user operation of the first switch control 102 is received, the SIM card locking function is turned ON in response to the user operation, and the first switch control 102 is switched from the display "OFF" state to the display "ON" state.

Password modification control 103 may be used to modify the PIN code of the locked SIM card. Specifically, after the SIM card locking function is started, a PIN code input by a user is received. When the user needs to update the input PIN code, the user operation of the password modification control 103 is received, and in response to the user operation, the PIN code modification interface 12 (refer to fig. 4) is popped up for the user to modify the PIN code.

In some embodiments of the present application, in particular implementations, in order to facilitate a user to efficiently and conveniently input a PIN code to unlock the SIM card after locking the SIM card, when the SIM card is started (e.g., when the SIM card is powered on), if the SIM card is set with the PIN code and a password-free input mode is set (after the SIM card is set with the mode, a scenario may be enabled that, when unlocking the SIM card, the user does not manually input the PIN code, the electronic device 100 uses a password-free input mode to unlock the SIM card, e.g., the electronic device 100 may automatically fill a stored PIN code into a password frame of the PIN code to be input or automatically send the stored PIN code to a module corresponding to the SIM card to unlock the SIM card), then the electronic device 100 determines to unlock the SIM card according to first information, where the first information is related to a state change of the SIM card and/or a state change of the electronic device 100, and the first mode is a password-free input mode.

The method of unlocking the SIM card by unlocking the SIM card will be described in detail using the setting interface 10 for locking the SIM card shown in fig. 3 as an example. It should be noted that, before unlocking the locked SIM card, a PIN code for locking the SIM card needs to be set first, and after setting the PIN code, the wind control component is started. As shown in fig. 6, the method for setting the locked SIM card at least includes the following steps:

step S601: and responding to the instruction of locking the SIM card, and opening the SIM card lock.

In this embodiment, in response to the user's operation ON the first switch control 102 in the SIM card locking setting interface 10 shown in fig. 3, an instruction for locking the SIM card is generated, specifically, the mobile phone responds to the user's operation of selecting the first switch control 102 to be in the ON state, generates an instruction for locking the SIM card, and opens the SIM card lock according to the instruction for locking the SIM card. The mobile phone responds to the operation that the user selects the first switch control 102 to be in the "OFF" state, generates an instruction for closing the SIM card lock, closes the SIM card lock according to the instruction for closing the SIM card lock, and closes the air control component.

Step S602, in response to the operation of setting the PIN code input mode to the password-free input mode, turning on the wind control component.

In this embodiment, the mobile phone also responds to the instruction for locking the SIM card to display a prompt interface 40 (as shown in fig. 5), where the prompt interface 40 displays a set PIN code input mode control 401. The PIN code input mode control 401 is set for setting different PIN code input modes. As shown in fig. 5, the set PIN code input mode control 401 has two display states, an "ON" state and an "OFF" state. Wherein, in response to the user setting the PIN code input mode control 401 to the "ON" state, the PIN code input mode is set to the password-free input mode, and in response to the user setting the PIN code input mode control 401 to the "OFF" state, the PIN code input mode is set to the manual input mode. When the PIN code input mode is in the password-free input mode, the password-free input PIN code is instructed to be started to unlock the SIM card, and when the PIN code input mode is in the manual input mode, the PIN code is instructed to be manually input to unlock the SIM card. Thus, the user can select the input mode of the PIN code according to the own requirement. In this embodiment, the wind control component is a set of program code, a software module or a hardware element (such as a chip), and is configured to detect a state change of the mobile phone and/or a state change of the SIM card, and use the state change of the mobile phone and/or the state change of the SIM card as a wind control factor, and calculate a risk value of mobile phone leakage data caused by the wind control factor.

Step S603, receiving the PIN code input by the user, and storing.

In this embodiment, after the wind control component is started, the mobile phone displays a PIN code input interface (refer to fig. 7) for the user to input the PIN code. The mobile phone receives the PIN code input by the user through the wind control component and stores the PIN code.

In step S604, the air control component detects the state change of the mobile phone and/or the state change of the SIM card in real time, and takes the state change of the mobile phone and/or the state change of the SIM card as an air control factor.

In this embodiment, after the SIM card locking function is opened and the PIN code input mode is set to be free of inputting the PIN code to unlock the SIM card, in a subsequent use process of the mobile phone, a state change of the mobile phone and/or a state change of the SIM card may be detected by the wind control component, the state change of the mobile phone and/or the state change of the SIM card are used as wind control factors, a risk value of mobile phone leakage data caused by the wind control factors is calculated by the wind control component, and how to input the PIN code to unlock the SIM card after the mobile phone is started or the SIM card is plugged is determined according to the height of the risk value. When the subsequent user restarts the mobile phone or inserts the SIM card, if the input PIN code is consistent with the PIN code stored in the SIM card, the SIM card can be unlocked, so that the mobile phone can access the SIM card, read related data, and realize the functions of accessing a network, dialing a phone and the like. The wind control component is used for calculating a risk value of the mobile phone according to the detected state change of the mobile phone and/or the detected state change of the SIM card as a wind control factor, and the specific description refers to FIG. 8.

In this embodiment, the method is further used for: in response to clicking the password modification control 103 of the setting interface 10 (refer to fig. 3), a modification PIN code interface 12 (refer to fig. 4) is displayed, a password input by a user at the modification PIN code interface 12 is received, and the received password is updated and stored as the PIN code. In this embodiment, the modification PIN interface 12 includes a password modification field 121, a confirmation control 122, and a cancel control 123. The password modification field 121 is configured to receive a password input by a user, and the confirmation control 122 is configured to respond to an operation of the confirmation control 122 by the user, and store the received password as the PIN code after determining that the password modification field 121 receives the password input by the user. The cancel control 123 is configured to respond to the user's operation on the cancel control 123, and is configured to cancel the modification of the PIN code this time.

It should be noted that the PIN code is information set in the SIM card, that is, the hardware information of the SIM card associated with the PIN code is not associated with other hardware (such as a mobile phone or a card slot). Specifically, in an application scenario, when the SIM card is inserted into the card slot of the mobile phone a, a first PIN code is set. And then the SIM card is inserted into a card slot of the mobile phone B, and the SIM card can be unlocked continuously by using the first PIN code. If the first PIN code is updated to the second PIN code through the mobile phone B. When the SIM card is inserted back into the card slot of the mobile phone a again, the SIM card may be unlocked by the second PIN code.

It should be noted that, by the method, the PIN code for locking the SIM card can be set, and the wind control component is started. In the subsequent process of using the mobile phone, the state of the mobile phone or the state of the SIM card in the mobile phone can be detected, the state of the mobile phone or the state of the SIM card is used as a wind control factor, the risk value of the mobile phone leakage data is calculated through the wind control component, and how to unlock the SIM card is determined according to the condition of the risk value. Specifically, as shown in fig. 8, the method for unlocking the SIM card of the SIM card is applied to a mobile phone, and at least includes the following steps:

step S801, the SIM card is started in response to the power-on operation of the user.

In this embodiment, the power-on operation includes an operation of inserting the SIM card into the card slot of the mobile phone when the mobile phone is powered on or an operation of restarting the entire mobile phone. When the mobile phone is detected to be started, the SIM card is inserted into a card slot of the mobile phone or the whole mobile phone is restarted, and the SIM card is started.

Step S802, the SIM card judges whether the PIN code is needed to unlock the SIM card. If the result is that the PIN code is needed to unlock the SIM card, step S803 is executed, otherwise, if the result is that the PIN code is not needed to unlock the SIM card, step S804 is executed.

Step S803, the SIM card continues to be loaded until the loading is completed. After the execution of step S803, the flow ends.

Step S804, the judging result is sent to the SIM card of the mobile phone, and the mobile phone waits to receive the PIN code sent by the mobile phone so as to check the PIN code.

In this embodiment, when the SIM card is powered on and started, if the SIM card does not open the SIM card lock, the judgment result is that the SIM card does not need the PIN code to unlock, and the direct loading of the SIM card is successful. If the SIM card is opened, the SIM card needs to input a PIN code to unlock, and waits for receiving the PIN code sent by the mobile phone to check the PIN code.

Step S805, the mobile phone determines whether the SIM card needs a PIN code to unlock according to the judging result. If the SIM card is determined to not need the PIN code to unlock according to the determination result, step S806 is executed, otherwise, if the SIM card is determined to need the PIN code to unlock according to the determination result, step S807 is executed.

Step S806, the mobile phone determines that the SIM card is loaded successfully.

In step S807, the mobile phone determines whether a password-free input mode for the SIM card has been turned on. If it is determined that the password-free input mode is unlocked, step S808 is performed, and if the password-free input mode is not unlocked, step S811 is performed.

Step S808, detecting the state change of the SIM card or the state change of the mobile phone through the wind control component, and determining the wind control factor according to the state change of the SIM card or the state change of the mobile phone.

In this embodiment, the mobile phone determines to unlock the SIM card according to a state change of the SIM card or a state change of the mobile phone, where the first mode is a password-free input mode and the second mode is a mode in which a user manually inputs a PIN code. After the secret-free input mode is set for the SIM card (or understood as enabling or starting the secret-free input mode), it is possible to start the secret-free input mode to unlock the SIM card, but the secret-free input mode is not necessarily used to unlock the SIM card every time as long as the secret-free input mode is set. In the above embodiment, whether to unlock the SIM card by adopting the password-free input mode or the PIN code manual input mode may be determined according to the state change of the SIM card and/or the state change of the electronic device 100, and some restrictions are imposed on the enablement of the password-free input mode of the SIM card in which the password-free input mode is set, so that it may be avoided that security risks caused by information leakage of the SIM card due to direct enablement of the password-free input mode without risk assessment in the case of abnormal or unsafe state of the SIM card and/or the electronic device may be avoided.

It should be noted that the state change of the SIM card includes, but is not limited to, changing the state of the SIM module interface from the state of not being connected to the SIM card to the state of being connected to the SIM card; the SIM module interface is changed from a state of being connected with the SIM card to a state of not being connected with the SIM card; the SIM card is changed from the working state to the non-working state; the SIM module interface 1 changes from a state in which the SIM card 1 is connected to a state in which the SIM card 1 is not connected, to a state in which the SIM card 2 is connected, and so on.

In this embodiment, whether the SIM card leaves the mobile phone may be used as the wind control factor. Specifically, in the process that the SIM card leaves the mobile phone, the SIM card is changed from a connection state to an unconnected state; and the SIM card is reinserted into the mobile phone, and the SIM card is changed from the unconnected state to the connected state. When the state of the SIM module interface is changed from the state of being connected with the SIM card to the state of not being connected with the SIM card, determining that the SIM card is disconnected, and recording a first time point; and when the state of the SIM module interface is changed from the state of not being connected with the SIM card to the state of being connected with the SIM card, determining that the SIM is reinserted into the mobile phone, and recording a second time point. Counting the first time length t of the SIM card leaving the machine according to the first time point and the second time point ₁ At a first time length t ₁ As a wind control factor.

In this embodiment, the time for plugging and unplugging the SIM card is used as the wind control factor. Specifically, after the SIM card is pulled out of the card slot of the mobile phone, the state of the SIM card is changed from the working state to the non-working state; and after the SIM card is inserted into the card slot of the mobile phone, the state of the SIM card is changed from the non-working state to the working state. When the SIM card is changed from the working state to the non-working state, determining the time for pulling out the SIM card, and recording a third time point; when the SIM card is changed from the non-working state to the working state, determining the time of inserting the SIM card into the mobile phone, and recording a fourth time point. Counting a second time length t of SIM card plug-in according to the third time point and the fourth time point ₂ For a second time length t ₂ As a wind control factor.

It will be appreciated that whether other SIM cards are inserted during the SIM card off-hook may also act as a wind control factor. The number m of other SIM cards inserted during the period after the SIM card is extracted and the in-place third time length t of the other SIM cards inserted during the period after the SIM card is extracted can be counted ₃ For a third time length t ₃ As a wind control factor. For example, the first SIM card is 10 a.m.: 00 leaves handset a, the second SIM card is 10 a.m.: 05 insert cell phone A and 10 AM: 10 leaving the mobile phone A; third SIM card at 10:15 minutes into the mobile phone A, and 10:25 separate the mobile phone A; the first SIM card 11 a.m.: 30 reinserting into handset a. The number of other SIM cards which are inserted during the period after the first SIM card is extracted is 2, and the other SIM cards are in place for a third time length t ₃ =25 min.

The state change of the mobile phone includes, but is not limited to, a time length of the mobile phone when the mobile phone is turned off. It can be understood that the risk of losing the mobile phone may exist when the mobile phone is turned off for too long, and the PIN code needs to be input when the mobile phone is turned on again after the mobile phone is turned off. In this embodiment, the power-off time of the mobile phone is used as the wind control factor. Specifically, the time point of mobile phone shutdown is recorded when the mobile phone is shutdown, the time point of mobile phone startup is recorded when the mobile phone is started next time, the shutdown time of the mobile phone is counted according to the time point of mobile phone shutdown and the time point of mobile phone startup next time, and the shutdown time of the mobile phone is used as an air control factor.

Step S809, calculating a risk value according to the wind control factor, and judging whether the risk value is smaller than a preset risk value.

And calculating a risk value of the mobile phone by using the state change of the SIM card as an air control factor through an air control algorithm, and determining a PIN code input mode according to the magnitude of the risk value.

In this embodiment, after determining a wind control factor according to a state change of a SIM card or a state change of a mobile phone, calculating a current risk by using the wind control factor, and if the current risk is a first risk, unlocking the SIM card in a first mode; and if the current risk is a second risk, unlocking the SIM card in a second mode, wherein the first risk is lower than the second risk.

Specifically, after calculating the risk value according to the wind control factor, determining whether the risk value is smaller than the preset risk value, and executing step S810 when determining that the risk value is smaller than the preset risk value; when it is determined that the risk value is greater than or equal to the preset risk value, step S811 is performed.

In one embodiment provided herein, when the SIM card is off-line for a first time period t ₁ As wind control factor, if the first time length t ₁ If the risk value is zero, determining that the risk value is small; if the first time length t ₁ Non-zero, determines that the risk value is large. Can also be based on the first time length t ₁ And judging the magnitude of the risk value. It can be appreciated that the risk of reinserting the SIM card back into the handset one day after leaving the phone is significantly greater than the risk of reinserting the SIM card back into the handset one minute after leaving the phone. Specifically, if the first time length t ₁ The risk value is determined to be large when the risk value is larger than or equal to a first preset time length; if the first time length t ₁ And if the risk value is smaller than the second preset time length, determining that the risk value is small. If the first time length t ₁ And when the first preset time length is smaller than the first preset time length and larger than or equal to the second preset time length, calculating the risk value by combining other wind control factors.

In another embodiment provided in the present application, when the second time length t is the time of plugging in and plugging out the SIM card ₂ As wind control factor, if the second time length t ₂ Overlong, determining that the risk value is large; if the second time length t ₂ And the risk value is small because of no length. Specifically, if the second time length t ₂ Greater than or equal to a third predetermined length of time (e.g., seven eight days), determining that the risk value is large; if the second time length t ₂ Less than a fourth predetermined length of time (e.g., one night), the risk value is determined to be small. If the second time length t ₂ And when the third preset time length is smaller than the third preset time length and larger than or equal to the fourth preset time length, calculating the risk value by combining other wind control factors.

In another embodiment provided in the present application, when other SIM cards are inserted as wind control factors during the period after the SIM card is pulled out, other S inserted during the period after the SIM card is pulled out may be countedNumber of IM cards m, in-place total time t of other SIM cards inserted during the time after the SIM card is extracted ₃ And according to the counted number m and the in-place total time t ₃ A risk value is determined.

In another embodiment provided in the present application, the risk value is calculated by a preset wind control algorithm based on the wind control factor, where a formula for calculating the risk value is as follows:

X＝((t ₁ ×n)×w ₁ +t ₂ ×w ₂ +(t ₃ ×m)×w ₃ )/T

wherein X is a risk value, t ₁ For the first time length, n is the number of times the SIM card is pulled out from the mobile phone, t ₂ For a second length of time t ₃ For the third time length, m is the number of other SIM cards inserted during the time after the SIM card is pulled out, T is the threshold time, w ₁ 、w ₂ And w ₃ Is a weight value. The threshold time is a well-determined reference value, and belongs to a safety threshold, for example, 1 hour, as a reference threshold.

Step S810, automatically acquiring the stored PIN code, and sending the acquired PIN code to the SIM card to unlock the SIM card.

In this embodiment, in order to ensure the security of the user data, only when the current risk value is smaller than the preset risk value, the password input is avoided by using an automatic filling mode, that is, the PIN code is automatically input to unlock the SIM card. Therefore, the safety of data in the mobile phone of the user can be guaranteed, the times that the user needs to manually input PIN to unlock the SIM card every time the user starts or restarts or reinserts the SIM card can be reduced, and the user experience is improved.

In step S811, the password input interface 60 (refer to fig. 7) is displayed, and the PIN code manually input by the user on the password input interface 60 is acquired.

In this embodiment, the PIN code input manner may be determined according to a comparison result between the risk value and a preset risk value. When the risk value is greater than or equal to the preset risk value (e.g. 1), the user is required to manually input the PIN to unlock the SIM card, and at this time, the mobile phone displays a password input interface 60 for the user to manually input the password. Referring to fig. 7, the password input interface 60 includes a password input field 61 and a virtual key 62. The password input field is used for the user to manually input the PIN code, and the virtual key 62 is used for the user to select the input PIN code. After receiving the PIN code manually input by the user, the mobile phone sends the PIN code to the SIM card, so that the user can manually input the PIN code to unlock the SIM card. When the risk value is smaller than the preset risk value, the user does not need to manually input the PIN code, the mobile phone system automatically acquires the stored PIN code and sends the acquired PIN code to the SIM card, so that the SIM card can be unlocked without secret input, and the SIM card can be unlocked under the condition that the user does not feel.

Step S812, the PIN code manually input is sent to the SIM card to unlock the SIM card.

Step S813, the SIM card verifies whether the PIN code is correct after receiving the PIN code sent by the mobile phone. If the PIN code is correct, step S803 is executed, otherwise, if the PIN code is incorrect, step S814 is executed.

In step S814, the SIM card is not loaded any more.

Step S815, the SIM card sends the verification result of the PIN code to the mobile phone.

Step S816, the mobile phone determines whether the verification result of the PIN code is correct. If the verification result of the PIN code is correct, step S806 is executed, otherwise, if the verification result of the PIN code is incorrect, step S817 is executed.

In step S817, the mobile phone displays a password input interface, obtains the PIN code manually input by the user in the password input interface 60 to unlock the SIM card, and updates the stored PIN code according to the obtained PIN code.

Step S818, send the PIN code to the SIM card. After the execution of step S818, step S813 is executed.

In this embodiment, after the SIM card is successfully unlocked, the electronic device 100 displays a startup password input interface, receives a startup password input by a user, and displays a main interface after the startup password is successfully started after verification.
