Facial behaviour of deception has emerged as an important topic in surveillance research. In this paper, we evaluate the facial behaviour of deception based on some of the cues identified in the literature. First, we present a short review of deception cues in facial behaviour. Then, we run a pilot study, using a rapport style one-to-one interview scenario, under controlled and experimental conditions. Following the standard practice, the experiment has been designed to incorporate three stages. Stage one: facilitation session, in which the baselines are established for each participant. Stage two: interrogation session, in which the participants are required to answer questions on two topics - one truthfully and one falsely. Stage three: self-reporting session, in which the participants are required to report the ground truth for stage two. Once the data regarding visible images of facial behaviour was collected, it was analysed and compared to the facial behaviour cues identified in literature. For statistical analysis, a non-parametric sign-test was selected. The results indicated that there is potential in applying facial behaviour as the cues in predicting deception. Finally, a discussion on future work introduce more subtle facial actions analysis is presented.
