## Highlights

The security of U.S. commercial aviation is a long-standing concern, and substantial efforts have been undertaken to strengthen it. One of these efforts is the development of a new Computer-Assisted Passenger Prescreening System (CAPPS II) to identify passengers requiring additional security attention. The development of CAPPS II has raised a number of issues, including whether individuals may be inappropriately targeted for additional screening, and whether data accessed by the system may compromise passengers' privacy. GAO was asked to determine (1) the development status and plans for CAPPS II; (2) the status of CAPPS II in addressing key developmental, operational, and public acceptance issues; and (3) other challenges that could impede the successful implementation of the system.
