UK police forces told to address concerns over facial recognition systems or face legal action

The UK’s police forces must address concerns over the use of facial recognition technology or they may face legal action, according to the UK’s privacy watchdog.

Information Commissioner Elizabeth Denham has said the issue is a priority for her office.

Campaign group Big Brother Watch suggested the technology has misidentified a “staggering” number of innocent people as criminal suspects.

The group made freedom of information requests of every UK police force, with two acknowledging that they are currently testing such cameras.

The Metropolitan Police used the technology at the Notting Hill Carnival in 2016 and 2017 as well as at a Remembrance Sunday event, incorrectly flagging up 102 people as potentially having committed crimes.

Of 2,685 matches made between May 2017 and March 2018, South Wales Police said 2,451 were made in error.
