Abstract

A user authentication apparatus and method using movement of a pupil is capable of rapidly and accurately performing authentication with high security by storing the respective frequencies of objects mechanically moving on a screen and security keys corresponding thereto, comparing a frequency detected from movement of a pupil gazing at any object with a frequency of the object, and performing the authentication based on a corresponding security key when the detected frequency is included in a predetermined range.

Claims

1. A user authentication apparatus using movement of a pupil, comprising:

an information storage configured to store security keys corresponding to frequencies of a plurality of respective objects;

a display configured to display more than one object having the respective security keys to move at corresponding frequencies;

a pupil position detector configured to detect a position of the pupil of a user for at least one time zone;

a frequency detector configured to detect a frequency based on the position of the pupil of the user for each time zone detected by the pupil position detector; and

a controller configured to recognize a security key corresponding to the frequency detected by the frequency detector based on the security keys corresponding to the respective frequencies stored in the information storage and perform user authentication using at least one recognized security key.

2. The user authentication apparatus according to claim 1, wherein the controller is configured to control the display so that the objects periodically and alternately appear at a first side and at a second side different than the first side on a screen.

3. The user authentication apparatus according to claim 1, wherein the controller is configured to control the display so that movement of the object on a screen has a sine wave.

4. The user authentication apparatus according to claim 1, wherein the controller is configured to control the display so that movement of the object on a screen has a triangular wave.

5. The user authentication apparatus according to claim 1, wherein the controller controls the display such that at least one object on a screen has a corresponding frequency.

6. A user authentication method using movement of a pupil, comprising:

storing, with an information storage, security keys corresponding to frequencies of the respective objects;

displaying, with a display, more than one object having the respective security keys to move at corresponding frequencies;

detecting, with a pupil position detector, a position of the pupil of a user for each time zone;

detecting, with a frequency detector, a frequency based on the position of the pupil of the user for each time zone detected by the pupil position detector; and

recognizing, with a controller, a security key corresponding to the frequency detected by the frequency detector based on the security keys corresponding to the respective frequencies stored in the information storage and performing user authentication using at least one recognized security key.

7. The user authentication method according to claim 6, wherein in the displaying, the objects are displayed so that the objects periodically and alternately appear at a first side and at a second side different than the first side on a screen.

8. The user authentication method according to claim 6, wherein in the displaying, the objects are displayed so that movement of the object on a screen has a form of a sine wave.

9. The user authentication method according to claim 6, wherein in the displaying, the objects are displayed so that movement of the object on a screen has a form of a triangular wave.
