Social media giant Facebook has launched the tool Moments in Canada and the EU after removing face recognition from the app – previously its launch on the continent and country was stalled over privacy concerns.The version of Moments used in the US uses facial recognition to help users find Facebook photos of themselves, their friends, and particular places. It collects these together for private viewing or sharing, using facial features, and the date, time, and location where the photos were taken. However, the version launched in the EU and US has been stripped of facial recognition technology and instead groups together multiple photos that “appear to include the same face”, according to the social media company (via TechCrunch). It does this by relying on a less accurate form of technology that uses object recognition to analyze the distance between a person's eyes and ears. That technique is known as “facial clustering”. It still sends pictures of people out to Facebook's servers, but that is all done in line with privacy rules in the EU and Canada – the pictures aren't stored and the actual comparison is done on the phone
