Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0056] Figure 1 It shows a schematic structural diagram of the system for preventing SIM card tracking provided by the embodiment of the present invention, Figure 2 It shows a schematic structural diagram of the device for preventing SIM card tracking provided by the embodiment of the present invention. SeeFigure 1 In the embodiment of the present invention, the system for preventing SIM card from being tracked includes: a device for preventing SIM card from being tracked and a server. The device for preventing SIM card from being tracked can be a device supporting mobile network communication such as a smart phone or a tablet computer.

[0057] See Figure 2 The device for preventing SIM card from being tracked includes: a first control module, a second control module, a first SIM card and a second SIM card, where: the first control module is connected to the user's real-name SIM card and the first SIM card; the second control module is connected to the second SIM card; the user's real-name SIM card has a SIM card number, and the first SIM card and the second SIM card are unregistered cards (blank cards) in the initial state and do not have SIM card numbers. Wherein, the first control module and the second control module can be set as one module or two modules in practical applications, which is not specifically limited in the present invention.

[0058] Figure 3 The flowchart of the method for preventing SIM card from being tracked provided by the embodiment of the present invention is shown. This method is applied to the above device. See Figure 3 The method for preventing SIM card from being tracked provided by the embodiment of the present invention includes:

[0059] S1. The first control module establishes a first network connection through the user's real-name SIM card.

[0060] Specifically, in the initial state of the device for preventing SIM card from being tracked, since the first SIM card and the second SIM card do not have SIM card numbers, the first control module can establish a first network connection through the user's real-name SIM card so as to assign SIM card numbers to the first SIM card and the second SIM card through this first network connection.

[0061] S2. The second control module sends a first card number reading instruction to the second SIM card and receives a first card number reading response returned by the second SIM card. The first card number reading response does not carry the SIM card number of the second SIM card.

[0062] Specifically, since the second SIM card is an unregistered card (blank card) in the initial state and does not have a SIM card number, when the second control module reads the SIM card number of the second SIM card, it cannot read the relevant information. Therefore, it is necessary to assign a SIM card number to the second SIM card.

[0063] S3. The second control module sends a first registration request to the first control module. The first registration request is used to request to obtain the first assigned SIM card number.

[0064] Specifically, since the second control module is not connected to the user's real-name SIM card, it is necessary to assign a SIM card number to the second SIM card through the first network connection.

[0065] S4. The first control module sends a first registration request to the server via the first network connection, receives the first registration response returned by the server, and sends the first registration response to the second SIM card. The first registration response carries a first allocated SIM card number, and the first allocated SIM card number is the second SIM card number.

[0066] Specifically, the first control module transparently transmits the first registration request. When the server receives the first registration request, it queries the SIM card matrix connected to the server, selects the first allocated SIM card number according to a preset selection method, and returns the first registration response to the device for preventing SIM card tracking. Among them, the SIM card matrix includes multiple real SIM cards with SIM card numbers obtained from the operator. The server can maintain the SIM card matrix and mark the card number as allocated after the first allocated SIM card number is assigned. The preset selection method can include random selection, selection calculated according to a preset algorithm, etc., and the present invention does not make specific limitations.

[0067] S5. The second control module obtains the second SIM card number, establishes a second network connection through the second SIM card, and uses the second network connection as the first current network connection.

[0068] Specifically, after the second SIM card is assigned a SIM card number, the device for preventing SIM card tracking can establish a network connection through the second SIM card for network communication.

[0069] S6. The first control module disconnects the first network connection.

[0070] Specifically, when performing network communication subsequently, the network connection established through the user's real-name SIM card is no longer used for communication, thereby avoiding the tracking of the user's real-name SIM card number.

[0071] S7. The first control module sends a second card number reading instruction to the first SIM card, and receives the second card number reading response returned by the first SIM card. The second card number reading response does not carry the first SIM card number.

[0072] Specifically, since the first SIM card is an unregistered card (blank card) in the initial state and does not have a SIM card number, when the first control module reads the first SIM card number, it cannot read the relevant information. Therefore, it is necessary to assign a SIM card number to the first SIM card.

[0073] S8. The first control module sends a second registration request to the second control module. The second registration request is used to request to obtain the second allocated SIM card number.

[0074] Specifically, since the first control module has disconnected the network connection of the user's real-name SIM card, it is necessary to allocate a SIM card number for the first SIM card through the second network connection.

[0075] S9. The second control module sends a second registration request to the server through the second network connection, receives the second registration response returned by the server, and sends the second registration response to the first SIM card. The second registration response carries a second allocated SIM card number, and the second allocated SIM card number is the first SIM card number.

[0076] Specifically, the second control module transparently transmits the second registration request. When the server receives the second registration request, it queries the SIM card matrix connected to the server, selects the second allocated SIM card number according to a preset selection method, and returns the second registration response to the device for preventing SIM card tracking. The server can maintain the SIM card matrix and mark the card number as allocated after allocating the second allocated SIM card number.

[0077] S10. The first control module obtains the first SIM card number, establishes a third network connection through the first SIM card, and uses the third network as the second current network connection.

[0078] Specifically, after the first SIM card is allocated a SIM card number, the device for preventing SIM card tracking can establish a network connection through the first SIM card for network communication.

[0079] S11. The first control module performs network communication through the second current network connection, and / or the second control module performs network communication through the first current network connection.

[0080] Specifically, in the actual process of network communication, it is possible to choose to perform network communication only using the second network connection, or only choose to use the third network connection for communication, or also use both the second network connection and the third network connection for network communication. Whether using the second network connection or the third network connection for network communication, it is not through the network connection established by the user's real-name SIM card for network communication, thus avoiding the tracking of the user's real-name SIM card number.

[0081] As an optional implementation manner of the embodiment of the present invention, the method for preventing SIM card tracking further includes: when a preset trigger condition is met, the first control module disconnects the third network connection, obtains a new first SIM card number, establishes a new third network connection through the first SIM card, and uses the new third network connection as the second current network; and / or when a preset trigger condition is met, the second control module disconnects the second network connection, obtains a new second SIM card number, establishes a new second network connection through the second SIM card, and uses the new second network connection as the first current network connection.

[0082] As an alternative embodiment of the embodiment of the present invention, the first control module obtaining the new first SIM card number includes: the first control module sending a first update request to the second control module, the first update request carrying the first SIM card number and being used to request to obtain the third allocated SIM card number; the second control module sending the first update request to the server through the first current network connection, receiving the first update response returned by the server, and sending the first update response to the first SIM card, the first update response carrying the third allocated SIM card number, and the third allocated SIM card number being used as the new first SIM card number; the first control module obtaining the new first SIM card number. The second control module obtaining the new second SIM card number includes: the second control module sending a second update request to the first control module, the second update request carrying the second SIM card number and being used to request to obtain the fourth allocated SIM card number; the first control module sending the second update request to the server through the second current network connection, receiving the second update response returned by the server, and sending the second update response to the second SIM card, the second update response carrying the fourth allocated SIM card number, and the fourth allocated SIM card number being used as the new second SIM card number; the second control module obtaining the new second SIM card number.

[0083] Wherein, when receiving the first update request, the server releases the second allocated SIM card number, queries the SIM card matrix connected to the server, selects the third allocated SIM card number according to a preset selection method, and returns the first update response to the device for preventing the SIM card from being traced; when receiving the second update request, the server releases the first allocated SIM card number, queries the SIM card matrix connected to the server, selects the fourth allocated SIM card number according to a preset selection method, and returns the second update response to the device for preventing the SIM card from being traced. After receiving the update request, the server marks the SIM card number carried in the update request as unallocated and selects a new SIM card number for allocation.

[0084] Specifically, when updating the first SIM card number and the second SIM card number, it is possible to choose to update only one SIM card number or update them separately, which is not specifically limited in the present invention. Since the SIM card number can be dynamically updated, it is further possible to prevent the SIM card number from being traced.

[0085] Wherein, the preset trigger conditions include reaching a preset period, receiving a preset instruction, and triggering a preset event. For example, the SIM card number is updated every one hour; or after receiving the SIM card number update instruction, the SIM card number is updated, and the SIM card number update instruction can be initiated by the user or a third party; or it is triggered after the password input error reaches a threshold.

[0086] It can be seen that by using the method for preventing SIM card tracking provided by the embodiments of the present invention, network connection is performed using the SIM card number assigned by the server, and network communication is not performed through the network connection established by the user's real-name SIM card, thereby avoiding the tracking of the user's real-name SIM card number.

[0087] The following briefly describes the functions of the device and system for preventing SIM card tracking provided by the embodiments of the present invention in conjunction with Figure 1 and Figure 2 For other matters not covered, please refer to the relevant descriptions in the method for preventing SIM card tracking, and details will not be elaborated here.
