NEC has announced that it will provide a large-scale facial recognition system for the 2020 Summer Olympic and Paralympic Games in Tokyo. The system will be used to identify over 300,000 people at the games, including athletes, volunteers, media, and other staff. It's the first time that facial recognition technology will be used for this purpose at an Olympic Games. NEC's system is built around an AI engine called NeoFace, which is part of the company's overarching Bio-IDiom line of biometric authentication technology. The Tokyo 2020 implementation will involve linking photo data with an IC card to be carried by accredited people.
