[0002] With the popularity of smart phones, SIM (Subscriber Identity Module) cards have become a key carrier for user identity authentication and mobile communications. However, the security of SIM cards is often overlooked, especially when users change devices or lose SIM cards, there are great security risks. The PIN (Personal Identification Number) code of a newly purchased SIM card is usually in an invalid state, that is, it can be used without entering a PIN code. Many users lack understanding of this, resulting in potential risks to the user's personal information, mobile payment functions, and financial data related to bank cards and credit cards after the SIM card is lost or stolen.

[0070] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0071] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present application, rather than all of the embodiments.

[0072] The present application provides a SIM card security protection method, which can be applied to a SIM card or an ESIM card (Embedded SIM, embedded SIM card). Figure 1 The following is an application scenario diagram of the SIM card security protection method in an embodiment. The user's mobile device 200 interacts with the operator's data SMS server 100 through the SMS channel, and the user's mobile device 200 interacts with the SIM card 300 through the machine-card interface. When the user identification module SIM card 300 is first implanted in the user's mobile device 200, a binding request is sent to the operator's data SMS server 100 to bind the SIM card with the current device and user information; each time the SIM card is powered on, it is determined whether the implanted device of the SIM card has changed; if the implanted device of the SIM card has changed, the personal identification code verification function of the SIM card is activated, and a verification prompt message is output; the verification prompt message is used to prompt the user to enter the personal identification code of the SIM card; in response to the target personal identification code entered by the user, it is determined whether the networking function of the SIM card is enabled.

[0073] In one embodiment, Figure 2 As shown, a SIM card security protection method is provided. This embodiment of the application takes the method applied to a SIM card as an example for explanation, and the method includes the following steps:

[0074] S21. When a subscriber identity module SIM card is first implanted into the current device, a binding request is sent to the operator's data SMS server to bind the SIM card with the current device and user information.

[0075] Among them, the operator data SMS server is the key equipment used by operators to manage and process SMS messages.

[0076] Specifically, when the SIM card is activated on the device for the first time, a binding request is sent to the operator's data SMS server to bind the SIM card with the current device and user information.

[0077] For example, when the SIM card is first activated on the device, a data SMS will be sent to the operator's pre-known number, and the background will bind the device identification number, the SIM card's IMSI (International Mobile Subscriber Identity) or ICCID (Integrated Circuit Card Identification) and the user's identity information to the operator for record. Among them, data SMS (Short Message Service, SMS) is a text message transmission service based on mobile communication networks, which allows users to send and receive short text messages through mobile phones or other mobile devices, and the length of each message is usually limited to 160 characters.

[0078] Optionally, the above step S21 (sending a binding request to the operator data SMS server to bind the SIM card with the current device and user information) can be implemented as follows:

[0079] A. Send a binding request to the operator's data SMS server.

[0080] The binding request carries user identity information, identification information of the SIM card and current device information.

[0081] B. Receive the binding status information sent by the operator's data SMS server.

[0082] C. When the binding status information indicates successful binding, save the binding status information into the device information list.

[0083] D. When the binding status information indicates that the binding fails, output a prompt message.

[0084] The prompt information is used to prompt the user to re-bind or abandon the binding.

[0085] Specifically, a binding request is sent to the operator's data SMS server, which carries the user's identity information, the SIM card's identification information, and the current device information. The operator's data SMS server replies with a text message of the binding result to the SIM card. If the binding is successful, the SIM card saves the current device's bound status information to the device information list. If the binding fails, a prompt message is output to prompt the user to re-bind or give up the binding.

[0086] In some embodiments, before executing the above step S21 (when the subscriber identity module SIM card is first implanted into the current device), the following steps may also be performed:

[0087] When the SIM card is powered on, the bound device information of the SIM card is obtained;

[0088] Determine whether the bound device information of the SIM card is empty;

[0089] If the binding device information of the SIM card is empty, it is determined that the SIM card is implanted into the current device for the first time.

[0090] Specifically, when the SIM card is powered on and initialized, the bound device information in the card is read to determine whether the bound device information of the SIM card is empty. If it is empty, it is determined that the SIM card is implanted in the current device for the first time and has not been bound to the device information of the current device.

[0091] S22. Each time the SIM card is powered on and started, determining whether the implanted device of the SIM card is changed.

[0092] Specifically, when a user starts a device, the SIM card performs a device security check during each startup process to confirm whether the device has been changed.

[0093] Optionally, the above step S22 (determining whether the implanted device of the SIM card is changed each time the SIM card is powered on) can be implemented as follows:

[0094] Obtain a list of device information stored in the SIM card;

[0095] The device information list stores the device information bound to the SIM card.

[0096] When the bound device information of the SIM card is not empty, judging whether the implanted device of the SIM card is changed according to the bound device information of the SIM card and the device information list;

[0097] If the binding information of the SIM card belongs to the device information list, it is determined that the implanted device of the SIM card has not been changed;

[0098] If the binding information of the SIM card does not belong to the device information list, it is determined that the implanted device of the SIM card has been changed.

[0099] Specifically, during each startup process, a device security check is performed to determine whether the current device information is consistent with the device information stored in the device information list of the SIM card. If the binding information of the SIM card belongs to the device information list, it is determined that the implanted device of the SIM card has not changed; otherwise, it indicates that the implanted device of the SIM card has changed.

[0100] S23: If the implanted device of the SIM card is changed, the personal identification code verification function of the SIM card is activated, and verification prompt information is output.

[0101] The verification prompt information is used to prompt the user to input the personal identification code of the SIM card.

[0102] Specifically, if a device change is detected, the SIM card will automatically activate the PIN code. At this time, the user must enter the correct PIN code to continue using the SIM card.

[0103] In some embodiments, if the implanted device of the SIM card is changed, the permission management function of the SIM card is disabled; the permission management function of the SIM card includes: modifying the user's personal identification code, accessing the management file of the SIM card, and reading the user area data of the SIM card.

[0104] Specifically, when the PIN code is activated, the SIM card will enhance the protection of management rights and access, prohibit operations such as file scanning and PIN modification, and lock the user area data.

[0105] S24: In response to the target personal identification code input by the user, determine whether to enable the networking function of the SIM card.

[0106] Specifically, if the PIN code entered by the user is correct, it means that the PIN code verification is successful, and then the SIM card enters the power-on process and performs the network access operation.

[0107] In some embodiments, after executing the above step S24 (determining whether to enable the networking function of the SIM card in response to the target personal identification code input by the user), the following steps may also be executed:

[0108] If the personal identification code of the SIM card is successfully verified, the authentication is performed and the device change notification is sent to the operator's data SMS server;

[0109] Receive device change verification SMS messages sent by the operator's data SMS server;

[0110] In response to a verification instruction input by a user for the device change verification SMS, the personal identification code verification function of the SIM card is released.

[0111] Specifically, after the SIM card is successfully connected to the network, the system will automatically send a device change SMS, asking the user to verify the device change. Only after receiving the user's confirmation reply will the SIM card be unblocked and resume normal function.

[0112] In some embodiments, in response to a verification instruction input by a user for the device change verification SMS, a permission management function of the SIM card is enabled.

[0113] Specifically, once the verification SMS is received, the SIM card PIN code will automatically become invalid, the original SIM card protection restrictions will be restored, and the relevant applications in the SIM card will be allowed to be used normally.

[0114] That is, after the verification is successful, the SIM card connects to the network and sends a device change notification to the operator's data SMS server. After receiving the user's verification SMS, the personal identification code verification function of the SIM card is released and the normal function of the SIM card is restored, further improving the security of the SIM card and preventing criminals from using the SIM card for illegal activities.

[0115] The present application provides a SIM card security protection method. When the SIM card is first implanted into the current device, a binding request is sent to the operator data SMS server to bind the SIM card with the current device and user information. When the SIM card is powered on and started each time, it is determined whether the implanted device of the SIM card has changed. If the implanted device of the SIM card has changed, the personal identification code verification function of the SIM card is activated, and a verification prompt message is output, wherein the verification prompt message is used to prompt the user to enter the personal identification code of the SIM card, and in response to the target personal identification code entered by the user, it is determined whether the networking function of the SIM card is enabled. In the process of firstly implanting the SIM card into the current device and starting it, the device and the SIM card are first bound, and then, in each SIM card startup process, a security check is performed on the device to determine whether the implanted device of the SIM card has changed. If the implanted device of the SIM card has changed, the personal identification code verification function of the SIM card is activated. Only when the user enters the correct personal identification code can the SIM card continue to be used. In this way, even in the case of device replacement or SIM card loss, the user's personal information and financial data can be ensured to be safe, and the SIM card can be effectively prevented from being illegally used, thereby improving the overall security of the SIM card and reducing the potential risks caused by the loss of the SIM card.
