Sensors and Connectivity series: Biometrics and Facial Recognition

Biometrics is the science and technology of analysing biological data. Biometric identifiers are distinctive, measurable characteristics that are unique to each individual, which fall under physiological traits or behavioural characteristics. Physiological traits would include facial recognition, whereas behavioural identifiers would be behaviours individual to a person such as hand writing or gait.


Biometric authorisation could replace tickets, increasing convenience for passengers by saving time on purchasing or retrieving their tickets at gates. This in turn would lead to less bottle necking around gates, allowing higher capacity in stations. Furthermore, using facial recognition could track fare evaders. Biometric measurements can be used for monitoring rail drivers such as using eye movement analysis to detect driver fatigue.
