Identity and liveness verification

A system, comprising:

• one or more processors;
• and
• a computer-readable storage device coupled to the one or more processors and having instructions stored thereon which, when executed by the one or more processors, cause the one or more processors to perform operations for at least partially authenticating a person presenting an identification to a machine, the operations comprising:
• receiving a color image and an infrared (IR) image, the IR image taken contemporaneously with the color image;
• providing a set of facial landmarks depicted in the color image;
• determining a depth value for each facial landmark in the set of color landmarks, depth values being provided from the IR image;
• determining an average depth difference based on at least a sub-set of facial landmarks in the set of facial landmarks;
• comparing the average depth difference to a difference threshold to provide a comparison;
• and
• selectively authenticating the person based on the comparison.
