1. A system comprising:
one or more infrared light sources;
a camera to:
acquire first image data at a first time when infrared light with a first polarization is being produced by at least one of the one or more infrared light sources, and
acquire second image data at a second time when infrared light with a second polarization is being produced by at least one of the one or more infrared light sources; and
a computing device comprising:
a memory storing computer-executable instructions; and
a hardware processor to execute the computer-executable instructions to:
generate third image data from the first image data, wherein the third image data depicts one or more external characteristics of a palm of a hand;
determine a first set of feature vectors using at least a portion of the third image data;
generate fourth image data from the second image data, wherein the fourth image data depicts one or more internal characteristics of the palm of the hand;
determine a second set of feature vectors using at least a portion of the fourth image data; and
determine, using one or more of the first set of feature vectors and one or more of the second set of feature vectors, a current signature.
