Police face recognition skeptics will mainly site its unreliability as a main factor for their distrust. What if an innocent person is flagged because of this technology? It seems like their concerns have been warranted to some extent. South Wales Police are facing a backlash after they released data showing that their face recognition trial at the 2017 Champions League final misidentified thousands as potential criminals. Out of 2,470 initial matches, 2,297 were false positives that are about 92 percent and that’s a big margin of error.
“Poor quality images” from Interpol and UEFA and the novelty of the technology was blamed by the police unit. In various conditions, no facial recognition system is 100% accurate and the unit also defended by saying that overall there had been 2,000 positive IDs in nine months with 450 arrests and no people mistakenly taken into custody. Although there have been false positives around events since last June, the accuracy of the system is believed to be improving.
