Our face is our most distinguishable feature. But to machines, our face is data and it's being transformed into a faceprint in somebody else's database. In this episode, meet a man whose life was ruined after facial recognition technology tied him to a crime he didn't commit; a father who's wired his home with face recognition technology to keep his autistic daughter safe; plus, exclusive access to the FBI Biometric Technology Center, where over half of American's biometrics have been uploaded into a database.
