Systems And Methods Of Biometric Analysis To Determine Lack Of Three-Dimensionality

A method of biometric analysis, comprising:

• illuminating an iris of a subject and at least a portion of a surrounding eye, ocular region and face of the subject with an illumination source of a biometric analysis system;
• 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 reflected light from the iris and the portion of the surrounding ocular region and face of the subject;
• receiving as input at an analysis module of the biometric analysis system the one or more images;
• analyzing the reflected light in the one or more images with the analysis module of the biometric analysis system;
• and
• determining a lack of three-dimensionality of the subject with the analysis module of the biometric analysis system based on the reflected light in the one or more images of the portion of the surrounding ocular region and face of the subject.

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 and at least a portion of a surrounding eye, ocular region and face of the subject with an illumination source of a biometric analysis system;
• 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 reflected light from the iris and the portion of the surrounding ocular region and face of the subject;
• receive as input at an analysis module of the biometric analysis system the one or more images;
• analyze the reflected light in the one or more images with the analysis module;
• and
• determine a lack of three-dimensionality of the subject with the analysis module based on the reflected light in the one or more images of the portion of the surrounding ocular region and face of the subject.
