“…This approach has been formulated, e.g., within the "Smart Borders" policy process in 2011 within the EU [17,18], which has to be distinguished from risk-inspired overall border policy management [19]. While the current risk-based paradigms take into account identification factors like personal data, biometrics, etc., at the border control point (BCP) only, it would be beneficial to consider other factors like voluntary information given by passengers, remote sensor data, and search lists of persons, whilst maintaining and fostering social, ethical, and privacy requirements [20,21].
