A kiosk at a departure location may collect information from a passenger. The information collected may include a passport, a boarding pass, a departure photo, and a departure voice recording. The information may be stored in an encrypted database. A kiosk at an arrival location may also collect information from the passenger. The information collected may include a passport, a boarding pass, an arrival photo, and an arrival voice recording. The kiosk may retrieve the departure photo and the departure voice recording from the encrypted database based on the passport and the boarding pass. The kiosk may then compare the arrival photo and departure photos, and similarly the arrival voice recording and departure voice recording, to authenticate an identity of the passenger.
