伦敦警察厅计划在英国最繁忙的购物街牛津街部署实时面部识别（LFR）摄像头，通过扫描行人面孔并与通缉犯名单进行比对来打击犯罪[1]。伦敦市长萨迪克·汗表示支持该举措，称其为打击犯罪的一部分[1]。伦敦市长办公室声称该技术已在伦敦警察厅的资助下部署，包括在地铁站试用[1]，并称过去一年威斯敏斯特地区犯罪案件减少了14,000起[1]。
这一计划面临人权组织的强烈反对[1]。自由人权组织（Liberty）指出，民众中有48%反对在没有可疑威胁的情况下扫描高街行人的面孔[1]。人权组织还指出该算法存在对黑人的歧视问题[1]。
The Metropolitan Police plan to install fixed live facial recognition (LFR) cameras on Oxford Street, London's busiest shopping district, to scan pedestrians' faces and cross-reference them against wanted criminal databases.[1] London Mayor Sadiq Khan has backed the initiative, framing it as part of broader efforts to tackle crime.[1]
The technology will be deployed in London's West End and Soho areas, with Khan indicating that LFR systems will be utilized on the newly pedestrianized section of Oxford Street.[1] According to the mayor's office, the facial recognition technology has already been deployed with Metropolitan Police funding, including trial runs at Underground stations.[1] Officials claim that Westminster recorded a 14,000-case reduction in crime over the past year.[1]
However, the proposal has drawn sharp criticism from civil rights advocates. Liberty, a human rights organization, reports that 48 percent of the public opposes scanning high street pedestrians' faces without credible threat indicators.[1] Rights groups have also raised concerns that the algorithm exhibits discriminatory bias against Black individuals.[1]
