When someone uploads a photo of you, we might suggest that they tag you in it. We're able to compare your friend's photos to information we've put together from your profile pictures and the other photos you're tagged in. If this feature is turned on for you, you can choose whether or not we suggest your name when people upload photos of you. Adjust this in your Timeline and Tagging settings.

We currently use facial recognition software that uses an algorithm to calculate a unique number (“template”) based on someone’s facial features, like the distance between the eyes, nose and ears. This template is based on your profile pictures and photos you’ve been tagged in on Facebook. We use these templates to help you tag photos by suggesting tags of your friends. If you remove a tag from a photo, that photo is not used to create the template for person whose tag was removed. We also couldn’t use a template to recreate an image of you.

If we can’t suggest a name automatically, we'll group similar photos together so you can tag them quickly.
