The way you walk could be used instead of fingerprinting at airports

You may want to watch your step when you enter an airport. Everyone walks slightly differently and scientists are developing technology that identifies individuals - including criminals - by looking at their gait. This system - which is a type behavioural biometric - could soon work in airports just like fingerprinting and eye-scanning technology. This non-intrusive technique, which uses pressure pads built into the floor of an airport, is around 99.3 per cent accurate at identifying people. The system looks at a person's gait rather than the footprint shape itself.
