Cameras British Police Unjustly Recognised Thousands Of People As Criminals: During the Champions League final in 2017, the Wales police deployed face recognition technology to detect criminals in Cardiff, but the system was wrong in 92 percent of cases.

The technology can scan large groups of people and compare their faces to a database of previously arrested people. Also happened with the 170,000 visitors who came to watch the final match in the Welsh capital.

The system identified 2,470 potential similarities between visitors and known criminals in the police database. But in 92 percent of the cases, 2,297 people, the system had misidentified the people, reports Planet Blog.

No unjust arrests
According to the Welsh police, no facial recognition system is 100 percent accurate. Since the police started testing in June 2017, over 450 people have already arrested thanks to the system.

No person would have arrested after being mistakenly recognised by the system.

The Welsh police blame the erroneous recognition for, among other things, ‘delivered images of poor quality’. Among others, Interpol and UEFA football association had supplied images of well-known criminals.

The Dutch police also use facial recognition, but for the time being on a smaller scale. In 2017, 93 suspects recognised by the system.
