Global IT firm Unisys has revealed that it is helping the U.S. Customs and Border Protection (CBP) agency test its biometric identity solution at the Otay Mesa border crossing in San Diego.The biometric checks are made on non-U.S. citizens leaving the country as they submit their machine-readable or RFID-enabled travel documents as well as facial and iris biometrics as they are exiting the United States.The test is designed to help determine the efficiency and accuracy of using biometric technologies in an outdoor, pedestrian environment, began in February and will run until May 2016.”Unisys worked with CBP to develop a border security solution designed to identify visa overstays and persons of interest, as well as improve reporting and analysis of international visitors,” said Amy Rall, group vice president for the Department of Homeland Security practice at Unisys Federal. “This solution can help us better track who is entering the country, why they are here, and how long they stay.”The new tests represent the next step in the innovations provided by Unisys to CBP's border protection program. Unisys announced in January it had provided a facial recognition solution to allow CBP to capture live facial images of travelers at John F. Kennedy International Airport, New York City.The new tests also represent the second phase of the project at Otay Mesa, which began in December 2015. At that time, the kiosks were deployed to obtain facial photographs and iris images from selected non-US citizens entering the country at the Otay Mesa pedestrian crossing. Not all non-US citizen travellers participate in the test; for example, children are not included.
