I have written about this before and I'll say it again, "Keep your kid off the internet."
“We are able to suggest that your friend tag you in a picture by scanning and comparing your friend’s pictures to information we’ve put together from your profile pictures and the other photos in which you’ve been tagged.”
Facial recognition, now being used by Facebook...how frightening. I'm a public figure of sorts and I don't want this. I google my name and I see lots of my pictures. It's scary for me, and I'm not YOUR CHILD.
