A man arrives at an airport for a flight, and as he goes through security the agent asks some questions. Did anyone help him pack his suitcase? What is the purpose of his trip? During the conversation, the agent enters answers and facial reactions into a computer pre-programmed with millions of pieces of information relating to the behavior of suspicious passengers. Such man-and-machine collaborations, in this instance to detect terrorists, are not yet in place at airports.
