This month, JFK airport began to rollout the use of “facial recognition technology” at three of its terminals. Other airports throughout the country will similarly begin such use gradually throughout 2016. The primary purposes are two-fold: (1) to identify and prevent unlawful entrance to the country by certain foreign nationals and (2) to streamline the process of entering the United States from an international flight.

“Facial recognition technology,” a subcategory of what is broadly defined as biometrics, is essentially the use of software to identify or verify a person solely from viewing a digital image or video frame. Some recognition algorithms look at distinguishing features of the face, whereas others use quantitative analysis to compare a particular face with a template so as to eliminate variances. The technology of facial recognition software gets byzantine quickly, and so this brief definition will have to suffice. The most prevalent use of this technology is in security systems.
