UK's controversial use of face recognition to be challenged in court

New Scientist 

The first legal battle in the UK over police use of face recognition technology will begin today. Ed Bridges has crowdfunded action against South Wales Police over claims that the use of the technology on him was an unlawful violation of privacy. He will also argue it breaches data protection and equality laws during a three-day hearing at Cardiff Civil Justice and Family Centre. Face recognition technology maps faces in a crowd then compares results with a "watch list" of images which can include suspects, missing people and persons of interest. Police who have trialled the technology hope it can help tackle crime but campaigners argue it breaches privacy and civil liberty.
