Despite repeated investigations showing that different fingerprint systems used by immigration and criminal agencies prevent information-sharing that would help keep terrorists from entering the country, U.S. Departments of Justice, State and Homeland Security have yet to agree on a uniform system.

CISAC affiliated faculty member Lawrence M. Wein and CISAC Fellow Manas Baveja studied the Department of Homeland Security's two-fingerprint system and found it inadequate, as Wein testified before Congress last fall. Aliya Sternstein of Federal Computer Week cites their research as she examines the problem in "Fingerprint standard still elusive" (see link below).
