The Department of Homeland Security has published a Privacy Impact Assessment Update for Secure Flight, a DHS program that compares airline passenger records with various watch lists. The assessment describes the agency's plans to expand the Known Traveler program so as to expedite airline screening for certain categories of individuals. The DHS also intends to incorporate into Secure Flight the Automated Targeting System, a controversial program that allows the government to assign a risk assessment number to individual travelers. That number provides the basis for further screening. In 2007, EPIC urged DHS to either suspend the Automated Targeting System or to fully apply all Privacy Act safeguards to any individual subject to ATS. In 2010, EPIC advocated for stronger privacy protections of DHS trusted traveler programs that compare passenger names against watch lists.
