Abstract
Given the frequent and often successful attempts at trafficking illegal items of high value across borders, many systems have been put in place (e.g. airport baggage screening) to detect such attempts. However, given the limitations of these current systems, this study investigated the prevalence of visible behavioural signatures to concealment that could be seen by a multiple camera set-up. Ten participants were asked to conceal a high value item of which they could keep if they could successfully lie to our “lie detector machine”. 13 cameras observing every visible area of each participant were used to collect over 500 videos for analysis of bodily movement. Each participant underwent a conceal condition and a separate baseline condition where they did not conceal any items. 1500+ quantitative measures of bodily movement, including response time, were performed. It was found that, in the conceal condition, response time to the critical question increased, hand movements decreased, blink rate increased, and the left foot was nearly always in front of the right. In conclusion it appears that, within our experiment, there do exist behavioural signatures for concealment that could be used in automated screening applications. Further work to address the limitations of this study including ecological validity will follow.
