ABSTRACT
Queuing at airport border controls is one of the bottlenecks in the flow of passengers, which results in a poor travel experience and in serious health risks, like COVID19, due to the concentration of people and contact surfaces [3]. To address this problem, biometrics-on-the-move removes physical barriers for passengers, while preserving security at a maximum level. In this paper we describe a prototype, tested at the Lisbon Airport, demonstrating biometrics-on-the-move technology, where airport passengers are authenticated at a distance without having to pass through physical barriers or contact surfaces. This new setting requires a careful design of the flow of passengers and liveness detection biometrics to allow the robust authentication of passengers and, more importantly, detect fraud attempts in the different points of the process. © 2021 IEEE.
