Abstract
A line-of-sight-based authentication apparatus and method are provided. In the method, a first image is generated by photographing the eyes of a person using first lighting generated on the same axis as a photographing axis of a camera and a second image is generated by photographing the eyes of the person using second lighting generated on a different axis from the photographing axis. Eye movements are tracked based on the first image and the second image and a track of the eye movements is identified. Then, it is determined if the identified track is the same as a track previously stored for authentication purposes.
Claims21
A line-of-sight-based authentication apparatus comprising:
- a photographing unit which generates a first image by photographing an eye of a person using first lighting generated on a first axis that is the same as a photographing axis of a camera and generates a second image by photographing the eye of the person using second lighting generated on a second axis different from the photographing axis of the camera;
- a track identifier which tracks movement of the eye based on the first image and the second image and identifies a first track of the movement;
- and
- a matching determiner which determines if the first track is the same as a previously stored second track within a predetermined threshold.
