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, said method comprising acts of:

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

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

sending activation signal by the server to an erase application stored in the mobile phone 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.

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

3. The method as claimed in claim 1, wherein the predetermined authentication parameter is transmitted to the owner by the server 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 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 is switched ON and said activated erase application always checks for the erase request from the server 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 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 selected from a group comprising mobile phone, telephone, computer and any other device capable of sending voice messages.

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

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

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

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

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

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