Surveillance cameras in shopping center billboards are being used to spy on you so you can be targeted with the “correct” advertisements.
The giant screens contain technology that can work out your age, gender and even what mood you’re in at the time.
How long customers look at certain adverts can also be monitored and the adverts being displayed can change depending on who is walking past.
The Sunday Times has discovered 50 of these screens so far across the UK, including several screens at Westfield shopping center in Shepherd’s Bush, London.
Companies promoting the system have claimed that it complies with the UK’s data protection laws because no individually identifying information is being collected or stored.
Therefore, there is no legal requirement to tell shoppers that they are being filmed.
Ocean Outdoor was one of the first companies to use this kind of public surveillance technology.
