UK police forces lobbied to use biased facial recognition technology

Exclusive: System more likely to suggest incorrect matches for images of women and Black people

Police forces successfully lobbied to use a facial recognition system known to be biased against women, young people, and members of ethnic minority groups, after complaining that another version produced fewer potential suspects.

UK forces use the police national database (PND) to conduct retrospective facial recognition searches, whereby a probe image" of a suspect is compared to a database of more than 19 million custody photos for potential matches.
