Facebook is now informing users around the world that it's rolling out facial recognition features. Users in the European Union and Canada will not be notified because laws restrict this type of activity in those areas. Neowin reports: With the new tools, you'll be able to find photos that you're in but haven't been tagged in; they'll help you protect yourself against strangers using your photo; and Facebook will be able to tell people with visual impairments who's in their photos and videos. By default, Facebook warns that this feature is enabled but can be switched off at any time; additionally, the firm says it may add new capabilities at any time. In its initial statement, Facebook said the following about the impersonation protections it was introducing: "We want people to feel confident when they post pictures of themselves on Facebook so we'll soon begin using face recognition technology to let people know when someone else uploads a photo of them as their profile picture. We're doing this to prevent people from impersonating others on Facebook."
