Abstract

A method and system for deleting data in a communication device sets a secure command in a predetermined communication device, determines if the predetermined communication device has been lost and/or stolen, invokes the secure command to delete data in the predetermined communication device if the predetermined communication device has been lost and/or stolen.

Claims

1. A computing system for deleting data in a communication device, the computing system comprising:

a setting module configured for setting a user name and a password, and setting a secure command for deleting the data stored in the communication device;

a comparing module configured for comparing textual data of a received short message with the secure command, and determining if the textual data of the received short message is substantially the same as the secure command;

an executing module configured for invoking the secure command to delete the data stored in the communication device if the textual data of the received short message is substantially the same as the secure command; and

at least one processor that executes the setting module, the comparing module, and the executing module.

2. The system according to claim 1, further comprising a verifying module configured for verifying if an original Subscriber Identity Model (SIM) card in the communication device has been replaced, prompting a user to input a user name and a corresponding password if the original SIM card has been replaced, and determining if the input user name and the input password are correct according to the set user name and the set password.

3. The system according to claim 2, wherein the executing module is further configured for invoking the secure command to delete the data stored in the communication device if the input user name and the input password are incorrect.

4. The system according to claim 1, wherein the comparing module is further configured for prompting a user that the communication device has received a new short message if the textual data of the received short message is different from the secure command.

5. The system according to claim 1, wherein the setting module is further configured for setting an identification code for identifying the secure command.

6. The system according to claim 5, wherein the secure command comprises the set user name, the set password, and/or the identification code.

7. The system according to claim 1, wherein the received short message is sent and received over a communication network, which is the Internet or a wireless cellular network.

8. A computer-implemented method for deleting data in a communication device, the method comprising:

setting a user name and a password, and setting a secure command for deleting the data stored in the communication device;

receiving a short message by the communication device;

comparing textual data of the received short message with the secure command, and determining if the textual data of the received short message is substantially the same as the secure command; and

invoking the secure command to delete the data stored in the communication device if the textual data of the received short message is substantially the same as the secure command.

9. The method according to claim 8, further comprising:

verifying if an original Subscriber Identity Model (SIM) card in the communication device has been replaced before the step of receiving a short message by the communication device; and

executing the step of receiving a short message by the communication device, if the original SIM card has not been replaced;

or

executing an identity authentication procedure if the original SIM card has been replaced.

10. The method according to claim 9, wherein the identity authentication procedure comprises:

prompting a user to input a user name and a corresponding password;

determining if the input user name and the input password are correct according to the set user name and the set password; and

entering an operating system of the communication device if the input user name and the input password are correct, and executing the step of receiving a short message by the communication device;

or

invoking the secure command to delete the data stored in the communication device, if the input user name and the input password are incorrect.

11. The method according to claim 8, further comprising:

prompting that the communication device has received a new short message if the textual data of the received short message is different from the secure command.

12. The method according to claim 8, wherein the step of setting a user name and a password, and setting a secure command for deleting the data stored in the communication device comprises:

setting an identification code for identifying the secure command.

13. The method according to claim 12, wherein the secure command comprises the set user name, the set password, and/or the identification code.

14. A storage medium having stored thereon instructions that, when executed by a processor, causing the processor to perform a method for deleting data in a communication device, the method comprising:

setting a user name and a password, and setting a secure command for deleting the data stored in the communication device;

receiving a short message by the communication device;

comparing textual data of the received short message with the secure command, and determining if the textual data of the received short message is substantially the same as the secure command; and

invoking the secure command to delete the data stored in the communication device if the textual data of the received short message is substantially the same as the secure command.

15. The medium according to claim 14, wherein the method further comprises:

verifying if an original Subscriber Identity Model (SIM) card in the communication device has been replaced before the step of receiving a short message by the communication device; and

executing the step of receiving a short message by the communication device, if the original SIM card has not been replaced;

or

executing an identity authentication procedure if the original SIM card has been replaced.

16. The medium according to claim 14, wherein the identity authentication procedure comprises:

prompting a user to input a user name and a corresponding password;

determining if the input user name and the input password are correct according to the set user name and the set password; and

entering an operating system of the communication device if the input user name and the input password are correct, and executing the step of receiving a short message by the communication device;

or

invoking the secure command to delete the data stored in the communication device, if the input user name and the input password are incorrect.

17. The medium according to claim 14, wherein the method further comprises:

prompting that the communication device has received a new short message if the textual data of the received short message is different from the secure command.

18. The medium according to claim 14, wherein the step of setting a user name and a password, and setting a secure command for deleting the data stored in the communication device comprises:

setting an identification code for identifying the secure command.

19. The medium according to claim 18, wherein the secure command comprises the set user name, the set password, and/or the identification code.
