Excerpt: “In 2019, the Privacy and Civil Liberties Oversight Board (‘PCLOB,’ or ‘the Board’) opened an oversight project on facial recognition and other biometric technologies in aviation security. PCLOB’s professional staff, under the direction of PCLOB Board members, reviewed program documentation, reports, and evaluations, and worked with Department of Homeland Security offices to understand the operations of the program. This report describes the key aspects of the Transportation Security Administration’s (TSA) use of facial recognition technology (FRT) to determine the identity of air travelers for security purposes. We also include an analysis of potential associated privacy and civil liberties risks and make recommendations to improve the program.”
