UK Train Stations use Amazon-Powered AI to Read People’s Mood

In the UK, a series of AI trials involving thousands of train passengers who were unwittingly subjected to emotion-detecting software raises profound privacy concerns. The technology, developed by Amazon and employed at various major train stations including London’s Euston and Waterloo, as well as Manchester Piccadilly, used artificial intelligence to scan faces and assess emotional states along with age and gender. Documents obtained by the civil liberties group Big Brother Watch through a freedom of information request unveiled these practices, which might soon influence advertising strategies.
