A comparison of invasive and noninvasive sensors in the concealed information test

Abstract

Rapid screening requires identifying individuals concealing information promptly and noninvasively. The standard Concealed Information Test (CIT) is not conducive to a rapid screening context, however, researchers are investigating the ability to conduct adaptations of the CIT using noninvasive sensors. The purpose of this paper is to propose a study that will investigate and compare the accuracy rates of electro dermal, oculometric, and vocalic measures in identifying concealed information. The ability to detect criminals and high-risk individuals rapidly and with stand-off methods during security screening has implications for a wide variety of applications. © 2012 IEEE.
