Airport screening procedures are more rigorous in the wake of security concerns, which can often lead to long lines of passengers waiting to get through security.
Some new security screening ideas that are being tested:
• In the traditional model, every open security lane requires an x-ray officer at the same location to scan and assess the contents of luggage. But lines can quickly bottleneck if there’s just one slowdown. Centralized image processing would allow images to be viewed by the next available officer, in a central area, and depending on what is discovered, the bag would be returned to the passenger or diverted to a search point.
• Both Geneva and London airports have tested biometric authentication and verification, where infra-red facial biometric technology was used to match a passenger’s face to a colour photograph in an e-passport.
• Multi-view x-rays and computed tomography could mean more items could be left in bags and still provide accurate explosive-detection capabilities.
