Abstract

A method and apparatus for providing security of a mobile terminal in various ways are disclosed. The present invention includes receiving a 1^st signal from a mobile communication network via a wireless communication unit, when the display unit is activated, displaying a 1^st substitute screen including a password input window on a display unit, inputting a password to the password input window, transmitting the inputted password to the mobile communication network via the wireless communication unit, if a 2^nd signal indicating that the password is valid is received from the mobile communication network in response to the transmission, canceling the 1^st substitute screen, and if a 3^rd signal indicating that the password is not valid is received, maintaining the 1^st substitute screen.

Claims

1. A mobile terminal, comprising:

a touchscreen;

a wireless communication unit configured to communicate data; and

a controller configured to;

control the touchscreen to display a substitute screen on the touchscreen in response to receiving at least a first signal via the wireless communication unit, wherein a text is displayed on the substitute screen, and

control the touchscreen to display a password input window in response to a touch drag input to a visual object displayed on the substitute screen and the visual object being moved to a specific region of the touchscreen.

2. The mobile terminal of claim 1, wherein when an invalid password is inputted to the password input window for a predetermined number of times, the controller controls the password input window to disappear from the substitute screen.

3. The mobile terminal of claim 1, wherein the first signal includes text information corresponding to the displayed text and a lock command for displaying the substitute screen.

4. The mobile terminal of claim 3, wherein the text information is input via a web application programming interface (API).

5. The mobile terminal of claim 1, wherein the substitute screen is displayed on an entire region of the touchscreen.

6. The mobile terminal of claim 1, wherein the controller is further configured to control a default lock screen or a home screen to not be displayed, after receiving the first signal.

7. The mobile terminal of claim 1, wherein the controller is further configured to output a sound when at least a second signal is received via the wireless communication unit.

8. The mobile terminal of claim 1, wherein the controller is further configured to perform a selective deletion of at least a part of storage of the mobile terminal, when at least a second signal is received via the wireless communication unit.

9. The mobile terminal of claim 8, wherein the selective deletion includes at least a factory reset or a deletion of data stored in a removable memory card.

10. The mobile terminal of claim 1, wherein the substitute screen is displayed on an entire region of the touchscreen.

11. The mobile terminal of claim 1, wherein after receiving the first wireless signal, the controller to control a default lock screen or a home screen to not be displayed.

12. The mobile terminal of claim 1, wherein the controller is further configured to output a sound in response to receiving at least a second wireless signal.

13. The mobile terminal of claim 1, wherein the controller is further configured to perform a selective deletion of at least a part of storage of the mobile terminal, when at least a second wireless signal is received.

14. The mobile terminal of claim 13, wherein the selective deletion includes at least a factory reset or a deletion of data stored in a removable memory card.

15. A method of a mobile terminal comprising:

receiving at least a first signal via a wireless communication unit;

displaying a substitute screen on a touchscreen in response to receiving at least the first signal;

displaying, on the substitute screen, a text;

displaying, on the substitute screen, a visual object;

receiving, at the substitute screen, a touch drag input to move the object to a specific region of the touchscreen; and

displaying, on the touchscreen, a password input window, in response to receiving the touch drag input.

16. The method of claim 15, further comprising:

receiving, at the password input window, an invalid password for a predetermined number of times; and

controlling the password input window to disappear from the substitute screen in response to receiving the invalid password for the predetermined number of times.

17. The method of claim 15, wherein the first signal includes text information corresponding to the displayed text and a lock command for displaying the substitute screen.

18. The method of claim 17, wherein the text information is input via a web application programming interface (API).

19. The method of claim 15, wherein displaying the substitute screen on the touchscreen includes displaying the substitute screen on an entire region of the touchscreen.

20. The method of claim 15, further comprising controlling a default lock screen or a home screen to not be displayed, after receiving the first signal.

21. The method of claim 15, further comprising:

receiving at least a second signal via the wireless communication unit; and

outputting a sound in response to receiving the second signal.

22. The method of claim 15, further comprising:

receiving at least a second signal via the wireless communication unit; and

performing a selective deletion of at least a part of storage of the mobile terminal, in response to receiving the second signal.

23. The method of claim 22, wherein performing the selective deletion includes performing at least a factory reset or a deletion of data stored in a removable memory card.

24. A mobile terminal, comprising:

a display; and

a controller configured to;

control the display to display a substitute screen in response to receiving at least a first wireless signal, wherein a text is displayed on the substitute screen, and

control the display to display a password input window in response to a touch drag input to move a displayed object to a specific region of the display.

25. The mobile terminal of claim 24, wherein in response to an invalid password being inputted at the password input window for a predetermined number of times, the controller controls the password input window to disappear from the display.

26. The mobile terminal of claim 24, wherein the first wireless signal includes text information corresponding to the displayed text and a lock command for displaying the substitute screen.

27. The mobile terminal of claim 26, wherein the text information is input via a web application programming interface (API).
