Abstract

Disclosed embodiments relate to a terminal having improved security and a method of releasing a locked state of a terminal. There is provided a terminal, including an input unit configured to receive dragging; a storage unit configured to store a password pattern; a control unit configured to compare the received dragging with the password pattern and release a locked state of the terminal according to the comparison result; and an output unit configured to display at least a part of a user interface including at least two markers arranged in a grid, wherein the user interface includes a first marker and a second marker, and the password pattern includes movement from the first marker to the second marker and movement from the second marker to the first marker.

First claim

The invention claimed is:

1. A terminal comprising:
a display;
an input unit configured to receive dragging input;
a storage unit configured to store a password pattern; and
a processor configured to:
control to display at least a part of a user interface including at least two markers arranged in a grid on the display if a state of the terminal is locked, and
in response to receiving dragging input on the displayed at least a part of a user interface, release a locked state of the terminal by comparing the received dragging input and the stored password pattern,

wherein the user interface includes a first marker and a second marker having different visibility from the first marker, and the stored password pattern includes movement from the first marker to the second marker and movement from the second marker to the first marker.

2. The terminal according to claim 1 , wherein the first marker has a first form and the second marker has a second form that is different from the first form.

3. The terminal according to claim 1 , wherein the user interface includes the at least two first markers that are arranged in a grid and the user interface includes the second marker that is arranged between two adjacent first markers among the first markers.

4. The terminal according to claim 1 , wherein the processor controls to display both the first marker and the second marker.

5. The terminal according to claim 1 , wherein the processor controls to display one of the first marker and the second marker, and not display the other of the first marker and the second marker.

6. The terminal according to claim 2 , wherein the user interface includes markers that are arranged in a 5×5 grid.

7. The terminal according to claim 2 , wherein one of the first marker and the second marker includes two concentric circles and the other of the first marker and the second marker includes one circle.

8. A method of releasing a locked state of a terminal, comprising:
storing a password pattern;
displaying at least a part of a user interface including at least two markers arranged in a grid on a display if a state of the terminal is locked;
receiving dragging input on the displayed at least a part of a user interface; and
releasing a locked state of the terminal by comparing the received dragging input with the stored password pattern,
wherein the user interface includes a first marker and a second marker having different visibility from the first marker, and the stored password pattern includes movement from the first marker to the second marker and movement from the second marker to the first marker.

9. A method of the claim 8 , wherein the first marker has a first form and the second marker has a second form that is different from the first form.

10. A method of the claim 8 , wherein the user interface includes the at least two first markers that are arranged in a grid and the user interface includes the second marker that is arranged between two adjacent first markers among the first markers.

11. A method of the claim 8 , wherein the displaying at least a part of a user interface includes displaying both the first marker and the second marker.

12. A method of the claim 8 , wherein the displaying at least a part of a user interface includes displaying one of the first marker and the second marker, and not displaying the other of the first marker and the second marker.

13. A method of the claim 8 , wherein the user interface includes markers that are arranged in a 5×5 grid.

14. A method of the claim 8 , wherein one of the first marker and the second marker includes two concentric circles and the other of the first marker and the second marker includes one circle.

15. A non-transitory computer-readable recording medium having recorded thereon a program, which, when executed by a computer, causes the computer to perform the method of claim 8 .
