Never forget a face? The rise of 'live' body-worn cameras
With the growing terrorist threat, the pressure on security and law enforcement agencies has never been greater. In the UK, for example, seven terrorist plots were dropped in 2017, while 34 people lost their lives because three were not. Reportedly, London's Metropolitan Police may even stop investigating 'low-level' crimes as they focus on gun crime, knife crime, sexual offences and terror attacks. Yet those behind such serious crimes are often known to the authorities - "on the radar, but not under the microscope", as BBC journalist Richard Watson put it. So how can technology help law enforcement cope with this rapidly evolving threat?
Facial recognition is evolving rapidly, with the potential to help first responders fight crime in a more efficient and effective way. This technology is now established as an accepted part of our everyday lives with eGates the norm in airports, and face recognition allowing login to many mobile phones and computers. Some commercial organisations have already adopted such technologies for safety purposes: one example is Careem, a ride-sharing company in the Middle East, which uses facial recognition to assure that the registered driver is the person actually driving the car you are about to get into.
