Abstract

The present application is directed to apparatuses and methods for preventing information disclosure. According to example embodiments of the present application, after a mobile terminal of a user is lost, a first short message may be sent to the mobile terminal through a short message network. When the mobile terminal determines that the received short message is the first short message, user information stored in the mobile terminal may be erased by the mobile terminal.

Claims

1. A computer server system, comprising:

at least one non-transitory storage medium comprising a set of instructions for preventing information disclosure from a mobile terminal;

at least one executing unit in communication with the storage medium, wherein when executing the set of instructions stored in the storage medium the executing unit is directed to perform a multiple protection procedure in the mobile terminal to;

receive a command from a user to lock the mobile terminal;

determine whether the mobile terminal is in connection with a first network;

when determining that the mobile terminal is in connection with the first network, send an instruction in a first form to the mobile terminal through the first network to lock the mobile terminal in a state unavailable for any operation other than receiving and verifying an unlocking password; and

when determining that the mobile terminal is not in connection with the first network, send the instruction in a second form to the mobile terminal through a second network.

2. The computer server system according to claim 1, wherein the first network is one of an Internet network and a short message network,

the first form of the instruction is one of a predefined Internet command and a predefined short message.

the second network is one of an Internet network and a short message network, and

the second form of the instruction is one of a predefined Internet command and a predefined short message.

3. The computer server system according to claim 1, wherein the instruction comprises at least one of a locking password or a ciphertext corresponding to the locking password.

4. The computer server system according to claim 3, wherein the locking password is same as the unlocking password.

5. The computer server system according to claim 1, wherein the instruction is further configured to instruct the mobile terminal to erase information predetermined by the user and stored in the mobile terminal.

6. The computer server system according to claim 1, wherein the instruction is further configured to instruct the mobile terminal to erase a predetermined portion of information stored in the mobile terminal.

7. A method for performing a multiple protection procedure to prevent information disclosure from a mobile terminal, comprising:

receiving, by a computer server system, a command from a user to lock the mobile terminal;

determining, by the computer server system, whether the mobile terminal is in connection with a first network;

when determining that the mobile terminal is in connection with the first network, sending, by the computer server system, an instruction in a first form to the mobile terminal through the first network to lock the mobile terminal in a state unavailable for any operation other than receiving and verifying an unlocking password

when determining that the mobile terminal is not in connection with the first network, sending, by the computer server system, the instruction in a second form to the mobile terminal through a second network.

8. The method according to claim 7, wherein the first network is one of an Internet network and a short message network,

the first form of the instruction is one of a predefined Internet command and a predefined short message.

the second network is one of an Internet network and a short message network, and

the second form of the instruction is one of a predefined Internet command and a predefined short message.

9. The method according to claim 7, wherein the instruction comprises at least one of a locking password or a ciphertext corresponding to the locking password.

10. The method according to claim 7, wherein the locking password is same as the unlocking password.

11. The method according to claim 7, wherein the instruction is further configured to instruct the mobile terminal to erase information predetermined by the user and stored in the mobile terminal.

12. The method according to claim 7, wherein the instruction is further configured to instruct the mobile terminal to erase a predetermined portion of information stored in the mobile terminal.

13. A mobile terminal, comprising:

at least one non-transitory storage medium comprising a set of instructions for preventing information disclosure;

at least one executing unit in communication with the storage medium, wherein when executing the set of instructions the at least one executing unit is directed to perform a multiple protection procedure to;

connect to at least one of a first network and a second network;

when the first network is connected, receive through the first network an instruction in a first form to lock the mobile terminal;

when the first network is not connected, receive through the second network the instruction in a second form to lock the mobile terminal; and

lock the mobile terminal in a state unavailable for any operation other than receiving and verifying an unlocking password according to the instruction.

14. The mobile terminal according to claim 13, wherein the first network is one of an Internet network and a short message network,

the instruction in the first form is one of a predefined Internet command and a predefined short message,

the second network is one of an Internet network and a short message network, and

the instruction in the second form is one of a predefined Internet command and a predefined short message.

15. The mobile terminal according to claim 13, wherein the at least one executing unit is further directed to erase at least one of

information predetermined by the user and stored in the mobile terminal according to the instruction;

or

a predetermined portion of information stored in the mobile terminal.

16. The mobile terminal according to claim 13, wherein the mobile terminal does not include a SIM card.

17. A method for performing a multiple protection procedure to prevent information disclosure from a mobile terminal, comprising:

connecting, by the mobile terminal, to at least one of a first network and a second network;

when the first network is connected, receiving, by the mobile terminal through the first network, an instruction in a first form to lock the mobile terminal;

when the first network is not connected, receiving, by the mobile terminal through the second network, the instruction in a second form to lock the mobile terminal; and

locking, by the mobile terminal, the mobile terminal in a state unavailable for any operation other than receiving and verifying an unlocking password according to the instruction.

18. The method according to claim 17, wherein the first network is one of an Internet network and a short message network,

the instruction in the first form is one of a predefined Internet command and a predefined short message,

the second network is one of an Internet network and a short message network, and

the instruction in the second form is one of a predefined Internet command and a predefined short message.

19. The mobile terminal according to claim 17, wherein the at least one executing unit is further directed to erase at least one of

information predetermined by the user and stored in the mobile terminal according to the instruction;

or

a predetermined portion of information stored in the mobile terminal.

20. The mobile terminal according to claim 17, wherein the mobile terminal does not include a SIM card.
