displaying at least one first fingerprint recognition icon and at least one second fingerprint recognition icon on a display device while the display device is in a lock state;
determining whether a touch input has been received from the at least one first fingerprint recognition icon or the at least one second fingerprint recognition icon;
when it is determined that the touch input has been received from the at least one first fingerprint recognition icon,
performing a fingerprint authentication process to determine whether fingerprint information of the touch input is authentic and releasing the lock state of the display device when it is determined the fingerprint information is authentic; and
when it is determined that the touch input has been received from the at least one second fingerprint recognition icon,
maintaining the lock state without performing the fingerprint authentication process.
2. The method according to claim 1 , further comprising:
receiving a password to release the lock state when the fingerprint authentication process determines the fingerprint information is not authentic.
3. The method according to claim 1 , wherein the releasing comprises releasing the lock state when a multi-fingerprint touch in which two or more of the at least one first fingerprint recognition icon are simultaneously selected is input.
4. The method according to claim 1 , further comprising:
displaying application icons on the display device;
receiving a multi-fingerprint touch including a first fingerprint touch input for selecting one of the application icons and a second fingerprint touch input for selecting a background screen of the display device;
determining whether the fingerprint information input from at least one of the first fingerprint touch input and the second fingerprint touch input is authentic; and
executing an application of the application icon selected by the first fingerprint touch input when the fingerprint information is determined to be authentic.
5. The method according to claim 4 , further comprising:
receiving a password to execute the application of the selected application icon when the fingerprint information is not authentic.
6. The method according to claim 1 , further comprising:
executing a pay application;
receiving a multi-fingerprint touch including a first fingerprint touch input for selecting one of a plurality of cards included in the pay application and a second fingerprint touch input for selecting a background screen of the display device;
determining whether the fingerprint information input from at least one of the first fingerprint touch input and the second fingerprint touch input is authentic; and
using the selected a card for performing a purchase.
7. The method according to claim 6 , the using of the selected card for performing the purchase occurs without performing an additional authentication step.
8. The method according to claim 1 , further comprising:
executing a banking application;
receiving a transfer amount;
determining an authentic condition among a plurality of different authentication conditions in response to the transfer amount; and
remitting the transfer amount when it is determined that the fingerprint information is authentic and the transfer amount satisfies the authentic condition.
9. The method according to claim 8 , wherein a number of fingerprints to be used for the fingerprint authentication process increases in response to an increase of the transfer amount.
10. The method according to claim 9 , wherein the fingerprint information is input as a multi-fingerprint touch in which a plurality of fingers are simultaneously touched.
11. The method according to claim 1 , further comprising:
executing a gallery application for displaying a current image on the display device;
receiving a multi-fingerprint touch including a first fingerprint touch input and a second fingerprint touch input; and
determining whether the fingerprint information input from at least one of the first fingerprint touch input and the second fingerprint touch input is authentic; and
displaying a next image on the display device when the fingerprint information is determined to be authentic.
12. The method according to claim 11 , further comprising: maintaining the current image displayed on the display device when the multi-fingerprint touch is not input.
13. The method according to claim 11 , further comprising:
maintaining the current image displayed on the display device when the fingerprint information is not authentic.
14. An electronic device comprising:
a fingerprint sensor for sensing a fingerprint when a display device is touched; and
a processor for displaying at least one first fingerprint recognition icon and at least one second fingerprint recognition icon on the display device while the display device is in a lock state and determining whether a touch input has been received from the at least one first fingerprint recognition icon or the at least one second fingerprint recognition icon,
when it is determined that the touch input has been received from the at least one first fingerprint recognition icon, the processor performs a fingerprint authentication process to determine whether fingerprint information of the touch input is authentic and releases the lock state of the display device when it is determined the fingerprint information is authentic; and
when it is determined that the touch input has been received from the at least one second fingerprint recognition icon, the processor maintains the lock state without performing the fingerprint authentication process.
15. The electronic device according to claim 14 , wherein after the lock state is released, a plurality of application icons are displayed on the display device, and when a multi-fingerprint touch including a first fingerprint touch input for selecting one of the application icons and a second fingerprint touch input for selecting a background screen of the display device is input, the processor authenticates the fingerprint information input from at least one of the first fingerprint touch input and the second fingerprint touch input and then executes the application icon selected by the first fingerprint touch input.
16. The electronic device according to claim 14 , wherein when a multi-fingerprint touch including a first fingerprint touch input for selecting one of a plurality of cards and a second fingerprint touch input for selecting a background screen of the display device is input after a pay application is executed, the processor authenticates the fingerprint information input from at least one of the first fingerprint touch input and the second fingerprint touch input and uses a card selected by the first fingerprint touch input to perform a purchase.
17. The electronic device according to claim 16 , wherein the processor performs the purchase using the selected card without an additional authentication process.
18. The electronic device according to claim 14 , wherein the processor applies different authentication conditions to the fingerprint authentication process according to a transfer amount when a banking application is executed.
19. The electronic device according to claim 18 , wherein the processor performs the authentication process using the fingerprint information of a first number of fingers when the transfer amount is a first value and using the fingerprint information of a second number of fingers larger than the first number when the transfer amount is a second value larger than the first value.
20. The electronic device according to claim 14 , wherein the processor authenticates the fingerprint information and then displays a next image when a multi-fingerprint touch including a first fingerprint touch input and a second fingerprint touch input is input after a gallery application is executed and a current image is displayed on the display device.
