Abstract

A method for user authentication in an electronic device includes: detecting at least one rotation of the electronic device; obtaining at least one rotation angle based on the detected at least one rotation; obtaining at least one code based on the at least one rotation angle and a user authentication angle, the user authentication angle being obtained from a user gaze point that is set, and storing the at least one code as an authentication code; and unlocking the electronic device in response to an input of a code matching the authentication code.

Claims

1. A method for user authentication in an electronic device, comprising:

detecting at least one rotation of the electronic device;

obtaining at least one rotation angle based on the detected at least one rotation;

obtaining at least one code based on the at least one rotation angle and a user authentication angle, the user authentication angle being obtained from a user gaze point that is set, and storing the at least one code as an authentication code; and

unlocking the electronic device in response to an input of a code matching the authentication code.

2. The method of claim 1, wherein the unlocking the electronic device comprises:

if an authentication code is pre-stored, determining that the at least one code matches the pre-stored authentication code; and

unlocking the electronic device if it is determined that the at least one code matches the pre-stored authentication code.

3. The method of claim 1, further comprising setting the user gaze point, wherein the setting comprises recognizing a point at which a user gazes and setting the recognized point as the user gaze point.

4. The method of claim 1, wherein the obtaining and storing the code comprises:

obtaining respective rotation angles based on a plurality of rotations of the electronic device that are detected;

obtaining codes based on the respective rotation angles and the user authentication angle; and

generating and storing a code set of the codes, and

the method further comprises unlocking the electronic device in response to an input of a code set matching the stored code set.

5. The method of claim 4, wherein the generating and storing the code set comprises generating and storing the code set of the codes in an order in which the respective rotation angles are obtained.

6. The method of claim 3, wherein the setting the user gaze point comprises setting a second user gaze point in response to a plurality of rotations of the electronic device being detected.

7. The method of claim 6, further comprising obtaining codes based on respective rotation angles obtained based on the plurality of detected rotations and user authentication angles, the user authentication angles being obtained from the user gaze point and the second user gaze point, and generating and storing a code set of the codes.

8. The method of claim 7, wherein the generating and storing the code set comprises generating and storing the code set of the codes in an order in which the respective rotation angles are obtained.

9. The method of claim 1, further comprising displaying a graphic gauge to indicate a rotation direction and a rotation angle of the electronic device.

10. The method of claim 9, wherein the detecting the at least one rotation comprises detecting the at least one rotation by recognizing at least one of a touch and a drag to rotate the graphic gauge.

11. An electronic device comprising:

a camera configured to recognize a gaze of a user;

a sensor unit configured to detect at least one rotation of the electronic device;

a storage unit configured to store the authentication code.

12. The electronic device of claim 11, wherein the processor is further configured to determine, if an authentication code is pre-stored, that the at least one code matches the pre-stored authentication code, and unlock the electronic device if it is determined that the at least one code matches the pre-stored authentication code.

13. The electronic device of claim 11, wherein the processor is further configured to recognize a point at which the user gazes and set the recognized point as the user gaze point.

14. The electronic device of claim 11, wherein the processor is further configured to obtain respective rotation angles based on a plurality of rotations of the electronic device that are detected, obtain codes based on the respective rotation angles and the user authentication angle, configured to generate and store a code set of the codes, and configured to unlock the electronic device in response to an input of a code set matching the stored code set.

15. The electronic device of claim 14, wherein the processor is further configured to generate and store a code set of the codes in an order in which the respective rotation angles are obtained.

16. The electronic device of claim 13, wherein the processor is further configured to set a second user gaze point in response to a plurality of rotations of the electronic device being detected.
