Border control: From Technical to Operational evaluation

One of the major advantages of face recognition, compared to other biometrics, is the ease-of-use: no contact with the sensor, fast, in-line with the human way of recognizing people. In a border control scenario, fully automated gates using face recognition have now been deployed. As a passenger may use an automated solution only once in his life, the deployed system must operate with as little active cooperation from the passenger as possible. One way of building an ergonomic, real time, face recognition system is the use of video cameras. In such operational systems, there are different methods to process video streams, using an “image based”, 1:1 face recognition algorithm. In the normal automated scenario, the facial information of the person trying to pass the gate is compared to a stored reference (in the case of facial recognition, it is usually stored in the passport chip).
