USER AUTHENTICATION METHOD, DEVICE FOR EXECUTING SAME, AND RECORDING MEDIUM FOR STORING SAME
First Claim
1. A user authentication method performed by a user authentication device, comprising:
- when image data of a user is received from an imaging device, detecting a facial area and facial feature points using individual frame images in the image data;
performing face authentication by matching the facial area with a specific face template;
performing password authentication by detecting whether eye winking occurs using an image of an eye region extracted using the facial feature points, by recognizing a password depending on a state of eye winking based on preset criteria, and by determining whether the recognized password matches a preset password; and
determining that authentication of the user succeeds based on results of the face authentication and results of the password authentication.

Abstract
The present invention relates to a user authentication method, a device for executing the same, and a recording medium for storing the same. A user authentication method executed in a user authentication device according to an embodiment of the present invention comprises: a step of, when image data of a user is received from an image photographing device, detecting a facial area and a facial feature point using each frame image of the image data; a step of performing a face authentication by matching the facial area with a predetermined face template; a password authentication step of detecting an eye winking using an image of an eye area extracted using the facial feature point, recognizing a password according to a state of the eye winking on the basis of a preconfigured reference, and checking whether the recognized password matches with a preconfigured password; and a step of determining that the user authentication is successful, on the basis of the results obtained from the face authentication and the password authentication.

14. A user authentication device, comprising:
-
a facial area detection unit for, when image data of a user is received from an imaging device, detecting a facial area and facial feature points using individual frame images in the image data; a first authentication unit for performing face authentication by matching the facial area with a specific face template; a second authentication unit for detecting whether eye winking occurs using an image of an eye region extracted using the facial feature points, recognizing a password depending on a state of the eye winking based on preset criteria, and determining whether the recognized password matches a preset password; and a determination unit for determining that authentication of the user succeeds based on results of the authentication by the first authentication unit and results of the authentication by the second authentication unit.
