Abstract

The invention provides an anti-theft method and client for a mobile terminal. Wherein, the anti-theft method for a mobile terminal comprises: receiving a background anti-theft opening instruction from a server, wherein the background anti-theft opening instruction carries verification information of the mobile terminal; parsing the background anti-theft opening instruction, obtaining the verification information and performing verification; and opening the anti-theft function in the background according to the background anti-theft opening instruction if the verification is passed. The embodiment of the invention can open the anti-theft function of a mobile terminal after the mobile terminal is lost, and then perform a corresponding anti-theft operation according to an anti-theft instruction, which achieves the beneficial effects of guaranteeing the security of the mobile terminal and fighting against theft crimes more reasonably and effectively.

Claims

1. An anti-theft method for a mobile terminal, applied in a mobile terminal of which the anti-theft function is not opened, comprising:

receiving a background anti-theft opening instruction from a server, wherein the background anti-theft opening instruction carries verification information of the mobile terminal;

parsing the background anti-theft opening instruction, obtaining the verification information and performing verification; and

opening the anti-theft function in the background according to the background anti-theft opening instruction if the verification is passed, wherein the verification information comprises a unique identity identification of the mobile terminal, at least one subscriber identity module (SIM) card number and user account information, wherein the unique identity identification is the international mobile equipment identity (IMEI), wherein the obtaining the verification information and performing verification comprises;

respectively verifying the IMEI and the at least one SIM card number in the verification information;

when the IMEI in the verification information matches the IMEI of the mobile terminal and the at least one SIM card number matches a SIM card number in a list of contacts of the mobile terminal, logging in the user account information to obtain an account identification (ID);

sending the account ID to the server; and

receiving a message of passing the account ID verification from the server, and

determining that the verification information passes the verification.

2. The method as claimed in claim 1, further comprising:

refusing to execute the background anti-theft opening instruction if the verification fails.

3. The method as claimed in claim 1, wherein, after the verification information passes the verification, there is further comprised:

identifying the at least one SIM card number as a trustworthy number;

after the opening the anti-theft function in the background according to the background anti-theft opening instruction, there is further comprised;

receiving an anti-theft instruction from a SIM card number identified as a trustworthy number; and

parsing the anti-theft instruction, and performing an anti-theft operation corresponding to the anti-theft instruction.

4. The method as claimed in claim 1, wherein the account information comprises a username and a password.

5. The method as claimed in claim 1, wherein, after opening the anti-theft function in the background according to the background anti-theft opening instruction, there is further comprised:

receiving an anti-theft instruction from the account ID; and

parsing the anti-theft instruction, and performing an anti-theft operation corresponding to the anti-theft instruction.

6. A mobile terminal, comprising:

a memory having instructions stored thereon;

a processor configured to execute the instructions to perform following operations;

receiving a background anti-theft opening instruction from a server, wherein the background anti-theft opening instruction carries verification information of the mobile terminal;

parsing the background anti-theft opening instruction, obtaining the verification information and performing verification; and

opening the anti-theft function in the background according to the background anti-theft opening instruction if the verification is passed, wherein the verification information comprises a unique identity identification of the mobile terminal, at least one subscriber identity module (SIM) card number and user account information, wherein the unique identity identification is the international mobile equipment identity (IMEI), wherein the obtaining the verification information and performing verification comprises;

respectively verifying the IMEI and the at least one SIM card number in the verification information;

when the IMEI in the verification information matches the IMEI of the mobile terminal and the at least one SIM card number matches a SIM card number in a list of contacts of the mobile terminal, logging in the user account information to obtain an account identification (ID);

sending the account ID to the server; and

receiving a message of passing the account ID verification from the server, and determining that the verification information passes the verification.

7. The mobile terminal as claimed in claim 6, the operations further comprising:

refusing to execute the background anti-theft opening instruction if the verification fails.

8. The mobile terminal as claimed in claim 6, wherein, after the verification information passes the verification, the operations further comprise:

identifying the at least one SIM card number as a trustworthy number;

after the opening the anti-theft function in the background according to the background anti-theft opening instruction, the operations further comprise;

receiving an anti-theft instruction from a SIM card number identified as a trustworthy number; and

parsing the anti-theft instruction, and perform an anti-theft operation corresponding to the anti-theft instruction.

9. The mobile terminal as claimed in claim 6, wherein, after opening the anti-theft function in the background according to the background anti-theft opening instruction, there is further comprised:

receiving an anti-theft instruction from the account ID; and

parsing the anti-theft instruction, and performing an anti-theft operation corresponding to the anti-theft instruction.

10. A non-transitory computer readable medium having instructions stored thereon that, when executed by at least one processor, cause the at least one processor to perform following operations:

receiving a background anti-theft opening instruction from a server, wherein the background anti-theft opening instruction carries verification information of the mobile terminal;

parsing the background anti-theft opening instruction, obtaining the verification information and performing verification; and

opening the anti-theft function in the background according to the background anti-theft opening instruction if the verification is passed, wherein the verification information comprises a unique identity identification of the mobile terminal, at least one subscriber identity module (SIM) card number and user account information, wherein the unique identity identification is the international mobile equipment identity (IMEI), wherein the obtaining the verification information and performing verification comprises;

respectively verifying the IMEI and the at least one SIM card number in the verification information;

when the IMEI in the verification information matches the IMEI of the mobile terminal and the at least one SIM card number matches a SIM card number in a list of contacts of the mobile terminal, logging in the user account information to obtain an account identification (ID);

sending the account ID to the server; and

receiving a message of passing the account ID verification from the server, and determining that the verification information passes the verification.
