Most people smile for the camera but many more may frown at the idea of facial recognition technology.
The Atlanta Journal Constitution reports RealNetworks, a Seattle-based technology firm, is working to perfect facial recognition hardware and software.
Though geared for private industry, they're giving this high-tech security system free to public schools.
John Whitehead of The Rutherford Institute is apprehensive about that.
"If they're studying some child in school and they make an error" he warns, "that kid can actually be pulled out of a class (and) charged with some kind of crime."
RealNetworks executives say a short-term goal is increased school safety but Whitehead, whose firm specializes in civil liberty cases to protect the public, says facial recognition is not foolproof and is favored by totalitarian regimes.
"So we gotta really be careful here," he complains. "I'm really upset that our government's not actually moving back on some of this stuff, passing some civil liberties laws to protect us and they're not doing it."
The news service also reports a digital privacy group lawyer is troubled that this technology is one more way school children are being trained to accept the invasion of their privacy by federal authorities.
