The Department of Homeland Security (DHS) and the United States Visitor and Immigrant Status Indicator Technology (US-VISIT) program is preparing to transition from a two print capture process to a 10-print slap capture process. In preparing for the 10-print pilot testing, a concern that the existing counters that house the fingerprint scanners are too tall… (More)
We describe the development of a computer-generated arena within which one can study human place learning by asking subjects to locate an invisible target. A series of studies demonstrate that such learning is based on acquiring knowledge about the spatial relations among the distal cues presented in this arena. We show that (1) the presence of proximal… (More)

This paper describes the development of a standards-based, repeatable, and reusable test and evaluation program for mobile biometric handheld devices. The goal is to develop a test framework based on cross-referenced, user-driven requirements and open, reusable test methods to determine if mobile biometric devices perform in accordance with their… (More)
Data quality limits the accuracy of biometrics. Poor data quality is responsible for many or even most matching errors in biometric systems and may be the greatest weakness of some implementations. This paper uses an expansive view of data quality focused on its implications for operational databases and systems. Data quality is defined here not just in… (More)
