Facebook runs advertisements that show users how to turn off facial recognition system and thus try to calm the outcry put forward by the users.
The feature uses facial recognition technology to identify people in photographs posted on Facebook, and then suggests to their friends that they should “tag” them so they are easier to find.
The move prompted concerns that photographs could be shared more widely than intended and provoked criticism that Facebook was “eroding the online privacy of its users by stealth”.
Facebook admitted it “should have been more clear” about the system and is now running advertisements on all user profiles that “help people to learn about the feature and how they can control it”. The advertisements, which according to Facebook have been displayed over 2.7 billion times, invite users to adjust their privacy settings.
