Abstract

Embodiments of the present disclosure relate to a method and system for remotely and automatically erasing information stored in SIM card memory and mobile phone memory including memory card of a mobile phone 101. The method includes sending a voice message comprising predetermined authentication parameters to a server 102 by an owner when the mobile phone 101 of the owner is lost. The method further includes authenticating the owner by the server 102 upon comparing the predetermined authentication parameters with the stored authentication parameters and sending activation signal by the server 102 to an erase application if the owner is authenticated. This signal will activate the erase application stored in the mobile phone 101 SIM card. The erase application generates destroy signal upon activation of the erase application to erase the information stored in the SIM card of the mobile phone 101.

Claims

1. A method for remotely and automatically erasing information stored in SIM card of a mobile phone 101, said method comprising acts of:

sending a voice message comprising predetermined authentication parameters to a server 102 by a owner when the mobile phone 101 of the owner is lost;

authenticating the owner by the server 102 upon comparing the predetermined authentication parameters with the stored authentication parameters;

sending activation signal by the server 102 to an erase application stored in the mobile phone 101 SIM card to activate the erase application when the owner is authenticated; and

generating destroy signal by the erase application upon activation of the erase application to erase the information stored in the SIM card of the mobile phone 101.

2. The method as claimed in claim 1, wherein the erase application is downloaded onto the mobile phone 101 SIM card from the server 102 upon owner registration confirmation with the server 102.

3. The method as claimed in claim 1, wherein the predetermined authentication parameter is transmitted to the owner by the server 102 upon owner registration.

4. The method as claimed in claim 1, wherein the predetermined authentication parameter is selected from a group comprising user name, password and combinations thereof.

5. The method as claimed in claim 1, wherein the server 102 optionally sends the erase request along with the predetermined authentication parameter to the erase application to authenticate the owner by the erase application.

6. The method as claimed in claim 5, wherein the erase application optionally authenticate the owner by comparing the received predetermined authentication parameter with stored authentication parameter.

7. The method as claimed in claim 5, wherein the erase application automatically activated whenever the mobile phone 101 is switched ON and said activated erase application always checks for the erase request from the server 102 to erase the information stored in the SIM card.

8. The method as claimed in claim 7, wherein the erase application waits for predetermined amount of time, preferably in the range of 1 sec to 5 sec, before getting deactivated when the erase request from the server 102 is not initiated.

9. The method as claimed in claim 1, wherein the destroy signal is selected from a group comprising short circuit signal, reset signal and malware.

10. The method as claimed in claim 1, wherein the owner sends the voice message using a communication device 103 selected from a group comprising mobile phone 101, telephone, computer and any other device capable of sending voice messages.

11. A method for automatically erasing information stored in a mobile phone 101 memory, said method comprising acts of

detecting removal of SIM card from the mobile phone 101;

and

generating destroy signal by activated erase application, if the SIM card is removed from the mobile phone 101, to erase the information stored in the mobile phone 101 memory.

12. The method as claimed in claim 11, wherein registered user of the mobile phone 101 has to deactivate the erase application by providing predetermined login information before removing the SIM card from the mobile phone 101 to avoid erase of information.

13. The method as claimed in claim 11, wherein the mobile phone memory comprises memory card.

14. The method as claimed in claim 11, wherein the destroy signal is selected from a group comprising short circuit signal, reset signal and malware.

15. A system for remotely and automatically erasing information stored in SIM card of a mobile phone 101, said system comprising

a mobile phone 101 with SIM card is configured to download erase application from a server 102;

the server 102 configured to receive erase request through voice message from the owner and to transmit activation signal to the erase application;

said server 102 authenticates the owner before transmitting the activation signal; and

a communication device 103 capable of sending erase request through the voice message to the server 102;

wherein said erase application generates the destroy signal upon receipt of activation signal from the server 102 to erase the information stored in SIM card of the mobile phone 101.
