BiometricsImproving speed, accuracy of biometric scanning at security checkpoints

Published 2 August 2018

Balancing speed and security at checkpoints, like airports, is essential to ensuring safe, reliable travel. Many of these checkpoints are increasingly using biometric technology to improve speed and reliability. While recent improvements in biometrics have lowered failure to match rates, many systems fail to quickly acquire biometric information in the first place. DHS S&T is working on designing a standard security checkpoint process to test the ability of biometric identity systems to acquire and match images from a diverse volunteer population within a realistic time constraint.

Balancing speed and security at checkpoints, like airports, is essential to ensuring safe, reliable travel. Many of these checkpoints are increasingly using biometric technology to improve speed and reliability. While recent improvements in biometrics have lowered failure to match rates, many systems fail to quickly acquire biometric information in the first place.

The Department of Homeland Security Science and Technology Directorate’s (S&T) first Biometric Technology Rally, held in March at S&T’s Maryland Test Facility (MdTF), aimed to eliminate these obstacles by testing face and face/iris recognition systems. S&T says that the MdTF designed a standard security checkpoint process to test the ability of biometric identity systems to acquire and match images from a diverse volunteer population within a realistic time constraint.

The Biometric Technology Rally builds off of recent S&T partnerships with the Transportation Security Administration (TSA) and Customs and Border Protection (CBP) to improve the speed and reliability of biometric systems.

“At Customs and Border Protection, our biggest challenge over the past several years has been collecting biometrics for people departing the United States where, unlike the arrivals process, we operate without a dedicated, secure environment,” said CBP Deputy Executive Assistant Commissioner John Wagner. “We are looking to work with partners and stakeholders to develop a process that doesn’t shut down travel, but enhances security and efficiency.”

Innovative systems from 11 industry participants representing 10 countries from around the world were selected to participate in the rally. S&T challenged industry to meet specific objective performance goals along three interlinked categories of evaluation metrics: effectiveness, efficiency, and satisfaction.

Effectiveness measured performance of the biometric system, including failures to acquire, process, and match images. S&T challenged industry systems to identify 99 percent of all volunteers using the system in under 20 seconds.

Efficiency measured the average time volunteers spent using each system. S&T challenged industry to design intuitive systems that volunteers could understand and use in just five seconds.
