Thermal facial screening for deception detection

Abstract

Our group has been conducting advanced research in deception detection (DD) for the last three years. The conclusion from our effort is that facial thermal screening is a very promising method for DD. It can be used as an additional information channel to enhance traditional polygraph examination for investigative purposes. Because of the unique advantages of the method (non-invasive, real-time, and highly automated), it can also be used for mass screening in airport, border, and other critical checkpoints. Checkpoint agents are already asking travelers certain questions. A familiar example is the question: "Did you pack your own bags?" The difference under our proposal is that these questions will become much more meaningful and both an agent and a machine will evaluate the travelers' responses. The machine's recommendation will serve as an additional data point to the traveler's on-line record. Its weight will be commensurate with how well the machine proves itself in actual practice.
