TOKYO -- The faces of nearly 500,000 travelers to Rio de Janeiro around the time of the Summer Olympics will fall under the gaze of airport security cameras linked to an electronic brain designed by Japan's NEC.
Rio de Janeiro International and Sao Paulo-Guarulhos International airports began using NEC's facial recognition system in the spring to be ready for the games. The technology captures faces via surveillance cameras and checks them against a photo database of felons and other people of interest. Officials are altered when a match is found.
