U.K. Information Commissioner Elizabeth Denham offered a Commissioner's Opinion regarding the use of facial recognition by private and public entities in public spaces. Denham explained "data protection and people’s privacy must be at the heart of any decisions to deploy (live facial recognition)" and the opinion aims to set "a high bar to justify the use of LFR and its algorithms." The opinion, according to Denham, is based off law and "six ICO investigations into the use, testing or planned deployment of LFR systems."
