Patent number: 9245173Abstract: An apparatus for identifying a fake face is provided. A first eye image acquirer acquires a first eye image by taking a picture of a subject while radiating a first ray having a first wavelength. A second eye image acquirer acquires a second eye image by taking a picture of the subject while radiating a second ray having a second wavelength that is shorter than the first wavelength. A controller extracts a first area and a second area having brighter lightness than the first area from each of the first and second eye images, calculates a lightness of the first area and a lightness of the second area in the first eye image, and a lightness of the first area and a lightness of the second area in the second eye image, and determines whether the subject uses a fake face based on the calculated lightness.Type: GrantFiled: February 21, 2013Date of Patent: January 26, 2016Assignee: SUPREMA INC.Inventors: Ki Deok Lee, Bo Gun Park, Ho Chul Shin, Bong Seop Song, Jae Won Lee
