How facial recognition could replace train tickets
A facial recognition system designed to replace the need for tickets on trains is being tested in the UK.
An early version that uses two near-infrared lights to help a single camera determine texture and orientation of each pixel it captures was shown to BBC Click.
The system, being developed by the Bristol Robotics Lab, is being partly funded by government and the private sector.
Researchers told the programme that they believe it will successfully identify passengers without the need for them to stop walking and could replace ticket gates.
This week BBC News is taking a close look at all aspects of cyber-security. The coverage is timed to coincide with the two biggest shows in the security calendar - Black Hat and Def Con.
Click's full report on biometric security is on the BBC News Channel, BBC World News and on BBC iPlayer (Uk only) on Saturday 29 and Sunday 30 July 2017 as part of the BBC's 'Cyberhacks' season.
