US Customs and Border Protection will begin using a facial comparison system on first-time Visa Waiver Program travellers and returning US citizens with ePassports at John F. Kennedy International Airport.According to a CBP statement on January 19, the technology compares an image of the traveller taken during the normal inspection process to the image stored on the traveller's ePassport, verifying that the traveller is the rightful document holder.The CBP stressed that images taken will be deleted unless CBP determines that further administrative or enforcement actions are necessary.”CBP continues to provide innovative technologies to enhance homeland security while facilitating international travel,” said Commissioner R. Gil Kerlikowske. “This biometric capability will aid our officers in identifying legitimate travelers while protecting them from fraud and identity theft with little to no delay to the entry process. CBP continues to implement technologies that benefit both national security and the traveler.”CBP tested facial comparison technology last year at Washington Dulles International Airport. The results of that testing determined the system successfully performed matches against actual passports and live captured images.CBP first established biometric screening procedures based on digital fingerprints for certain non-U.S. citizens in 2004 to secure our borders and ensure that the foreign travelers presenting themselves for admission to the United States are who they claim to be. CBP is conducting additional tests to evaluate new biometric technologies in multiple environments in FY 2016 to further secure and facilitate legitimate travel in a way that does not disrupt operations.Since 2007, U.S. passports have had a chip embedded in them that securely stores the same information that's on the photo page of the passport, which includes a biometric identifier in the form of a digital image of the passport photograph.This facilitates the use of facial comparison technology at ports of entry into the U.S. In order to maintain participation in the Visa Waiver Program, VWP countries also issue ePassports, which contain an electronic chip that holds the same information that is printed on the passport's data page: the holder's name, date of birth, and other biographic information, in addition to a digital photograph of the holder.
