1. A method, comprising:
capturing biometric data of a subject via at least one computing device;
rendering, on a display of the at least one computing device, at least two shape overlays and an instruction to:
trace a first shape overlay of the at least two shape overlays in a first color; and
trace a second shape overlay of the at least two shape overlays in a second color different from the first color;
during capture of the biometric data, receiving, via the at least one computing device, a tracing input corresponding to the at least two shape overlays, wherein the tracing input comprises a first tracing input for the first shape overlay and a second tracing input for the second shape overlay;
determining that the first tracing input is associated with the first color and the second tracing input is associated with the second color;
receiving the biometric data from the at least one computing device;
comparing the tracing input and the at least two shape overlays; and
based on the comparison, determining that the biometric data satisfies at least one liveness threshold.
 
9. A system, comprising:
a server having a processor operatively configured to:
receive captured biometric data of a subject from at least one computing device;
output instructions for rendering, on a display of the at least one computing device, at least two shape overlays and an instruction to:
trace a first shape overlay of the at least two shape overlays in a first color; and
trace a second shape overlay of the at least two shape overlays in a second color different from the first color;
receive biometric data and tracing input data from the at least one computing device, the tracing input data being indicative of a tracing input received by the at least one computing device simultaneously with the at least one computing device capturing the biometric data, and the tracing input data further corresponding to the at least two shape overlays, wherein the tracing input data comprises a first tracing input for the first shape overlay and a second tracing input for the second shape overlay;
determine that the first tracing input is associated with the first color and the second tracing input is associated with the second color;
compare the tracing input data and the at least two shape overlays; and
based on the comparison, determine that the biometric data satisfies at least one liveness threshold.
