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.

28. A biometric analysis system, comprising:
-
an illumination source configured to illuminate an iris of a subject to produce a retinal reflection of the subject; a camera configured to capture one or more images of the subject during illumination of the subject with the illumination source, the one or more images displaying the retinal reflection of the subject; and an analysis module configured to receive as input the one or more images, analyze the retinal reflection in the one or more images, and determine whether the retinal reflection exhibits a natural reflectivity of the retina. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 112, 113)

36. A method of biometric analysis, comprising:
-
illuminating an iris of a subject with an illumination source of a biometric analysis system to produce a retinal reflection of the subject; capturing one or more images of the subject with a camera of the biometric analysis system during illumination of the subject with the illumination source, the one or more images displaying the retinal reflection of the subject; receiving as input at an analysis module of the biometric analysis system the one or more images; analyzing the retinal reflection in the one or more images with the analysis module of the biometric analysis system; and determining with the analysis module of the biometric analysis system whether the retinal reflection exhibits a natural reflectivity of the retina. - View Dependent Claims (37, 38, 39, 40, 41, 42, 114, 115)

43. 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 iris of a subject with an illumination source of a biometric analysis system to produce a retinal reflection of the subject; capture one or more images of the subject with a camera of the biometric analysis system during illumination of the subject with the illumination source, the one or more images displaying the retinal reflection of the subject; receive as input at an analysis module of the biometric analysis system the one or more images; analyze the retinal reflection in the one or more images with the analysis module of the biometric analysis system; and determine with the analysis module of the biometric analysis system whether the retinal reflection exhibits a natural reflectivity of the retina.
