SYSTEM AND METHOD FOR PASSIVE LIVE PERSON VERIFICATION USING REAL-TIME EYE REFLECTION
First Claim
Patent Images
1. A method for authenticating a user of a device, comprising:
- defining a region of interest corresponding to a user'"'"'s eye;
calibrating a background pixel range of the region of interest of the user'"'"'s eye;
emitting a verification pattern from a display of the device;
capturing a reflected image of the verification pattern from the region of interest of the user'"'"'s eye; and
verifying a live user by comparing the captured reflected image to an expected pixel pattern.

Abstract
Systems, methods, and apparatus for detecting a live human face in an image are disclosed. The methods, systems, and apparatus are capable of capturing an image of a verification pattern that has been reflected from a defined region of interest of a user'"'"'s eye. The captured image can be compared to the emitted verification pattern to determine whether the captured reflection matches the emitted pattern and is within the region of interest to verify a live user of an electronic device.
