Privacy advocacy group Big Brother Watch lodged a complaint with the U.K. Information Commissioner’s Office over a facial recognition image database, BBC News reports. The database, PimEyes, reportedly allows users to search for facial images on the internet. Big Brother Watch said in its complaint to the ICO that PimEyes enabled "surveillance and stalking on a scale previously unimaginable." PimEyes CEO Giorgi Gobronidze said the database did not pose as many stalking risks as social media services.
