Facial Recognition Technology: Current and Planned Uses by Federal Agencies, Report to Congressional Requesters [open pdf - 5MB]
From the Highlights: "Facial recognition--a type of biometric technology--mimics how people identify or verify others by examining their faces. Recent advancements have increased the accuracy of automated FRT [facial recognition technology] resulting in increased use across a range of applications. As the use of FRT continues to expand, it has become increasingly important to understand its use across the federal government in a comprehensive way. GAO [Government Accountability Office] was asked to review the extent of FRT use across the federal government. This report identifies and describes (1) how agencies used FRT in fiscal year 2020, including any related research and development and interactions with non-federal entities, and (2) how agencies plan to expand their use of FRT through fiscal year 2023."
