Abstract

Provided are a method of restricting the use of a file, an electronic device, and a recording medium. The method of restricting the use of the file includes receiving an input of setting a region by a touch drag operation or a touch draw operation on a screen, receiving an input of a fingerprint of a user, and setting a lock on at least one file included in the region by matching the at least one file and the input of the fingerprint.

Claims

1. A method of restricting use of a file, comprising:

receiving an input of setting a region by a touch drag operation or a touch draw operation on a screen;

receiving an input of a fingerprint of a user; and

setting a lock on at least one file included in the region by matching the at least one file and the input of the fingerprint.

2. The method of claim 1, wherein the receiving the input of the fingerprint includes setting the region as a locked region, and wherein the setting the lock includes, dragging a file into the locked region and setting the lock on the file by matching the file and the input of the fingerprint.

3. The method of claim 1, wherein the receiving the input of setting the region includes displaying a lock region setting means capable of enlarging or reducing the region by the touch drag operation on the screen.

4. The method of claim 1, further comprising:

displaying the file on which set the lock on the screen;

receiving and sensing, when a target file on which is released the lock among the displayed files is selected or dragged out of the region, an input of a fingerprint for releasing the lock of the selected file; and

releasing the lock of the target file when the sensed fingerprint is authenticated.

5. A computer readable recording medium in which a program for executing the method according to claim 1 is recorded.

11. A computer readable recording medium in which a program for executing the method according to claim 2 is recorded.

12. A computer readable recording medium in which a program for executing the method according to claim 3 is recorded.

13. A computer readable recording medium in which a program for executing the method according to claim 4 is recorded.

6. An electronic device for restricting use of a file, comprising:

a lock region setting unit that receives an input of setting a region by a touch drag operation or a touch draw operation on a screen;

a fingerprint sensor unit that receives an input of a fingerprint of a user; and

a file locking management unit that sets a lock on at least one file included in the region by matching the at least one file and the input of the fingerprint.

7. The electronic device of claim 6, wherein the region is set as a locked region by the input of the fingerprint, and when dragging a file into the locked region, the file locking management unit sets the lock on the file by matching the file and the input of the fingerprint.

8. The electronic device of claim 6, wherein the lock region setting unit displays a lock region setting means capable of enlarging or reducing the region by the touch drag operation on the screen.

9. The electronic device of claim 6, wherein, when a target file on which is released the lock among the files is selected or dragged out of the region, the fingerprint sensor unit receives and senses an input of a fingerprint for releasing the lock of the selected file.

10. The electronic device of claim 9, wherein the file locking management unit releases the lock of the target file when the sensed fingerprint is authenticated.
