Abstract
Exemplary embodiments are directed to biometric analysis systems generally including one or more illumination sources, a camera, and an analysis module. The illumination sources are configured to illuminate at least a portion of a face of a subject. The camera is configured to capture one or more images of the subject during illumination of the face of the subject. The analysis module is configured to analyze the one or more images captured by the camera to determine an indication of liveliness of the subject and prevent spoofing.
Claims19
1-99. (canceled)
A biometric analysis system, comprising:
- an illumination source configured to illuminate an eye of a subject;
- a camera configured to capture one or more images of the eye of the subject during illumination of the eye with the first illumination source, the one or more images displaying a specularity characteristic of the eye;
- and
- an analysis module configured to receive as input the one or more images, analyze a brightness and uniformness of the specularity characteristic of the eye, and determine a three-dimensionality of the eye based on the specularity characteristic.
A method of biometric analysis, comprising:
- illuminating an eye of a subject with an illumination source of a biometric analysis system;
- capturing one or more images of the eye of the subject with a camera of the biometric analysis system during illumination of the eye with the first illumination source, the one or more images displaying a specularity characteristic of the eye;
- and
- receiving as input at an analysis module of the biometric analysis system the one or more images;
- analyzing with the analysis module a brightness and uniformness of the specularity characteristic of the eye;
- and
- determining a three-dimensionality of the eye with the analysis module based on the specularity characteristic.
A non-transitory computer-readable medium storing instructions for biometric analysis that are executable by a processing device, wherein execution of the instructions by the processing device causes the processing device to:
- illuminate an eye of a subject with an illumination source of a biometric analysis system;
- capture one or more images of the eye of the subject with a camera of the biometric analysis system during illumination of the eye with the first illumination source, the one or more images displaying a specularity characteristic of the eye;
- receive as input at an analysis module of the biometric analysis system the one or more images;
- analyze with the analysis module a brightness and uniformness of the specularity characteristic of the eye;
- and
- determine a three-dimensionality of the eye with the analysis module based on the specularity characteristic.
