Aviation Security: Challenges Delay Implementation of Computer-Assisted Passenger Prescreening System

The security of U.S. commercial aviation is a long-standing concern, and substantial efforts have been undertaken to strengthen it. One such effort 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 summarize the results of its previous report that looked at (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) additional challenges that could impede the successful implementation of the system.
