In the continued struggle to keep people clear of others infected with coronavirus, one tech company, ClearView, says its controversial facial recognition technology could help medical professionals clamp down on the virus’ spread. Indeed, technology has already been deployed in countries around the world to monitor the contact between its citizens. But researcher Stephanie Hare says this technology would be almost useless without increasing testing for the virus. And some, such as Gil Gan-Mor at Association for Civil Rights in Israel, are concerned the coronavirus emergency might be used as an excuse to increase the surveillance state. Though the BBC’s Rory Cellan-Jones thinks a lot of people would trade some of their civil liberties in exchange for going outside again.
