Digital Trends – The recent deployment of âTag Suggestionsâ on Facebook has been a hot topic of discussion for activists seeking more privacy controls. The Facebook feature is currently turned on for all users and uses facial recognition patterns to help users tag friends in photos. The software compares newly uploaded photos to previously tagged photos to search for a facial match. Users can easily opt out of allowing their face to by tagged in friend photos, but only a small portion of users are likely aware of the automatic tagging function.
