Automation takes a hand in passport control

By VINCENT KIERNAN in WASHINGTON DC Travellers entering the US are being asked to offer immigration officials a hand – quite literally – to test an automatic system for identifying passengers. The system, known as Inspass, aims to speed travellers through immigration controls by identifying them from the structure of their hands. Inspass provides each traveller with a smart card, like a cash card, on which is recorded a mathematical description of the shape of their hand. On arrival in the US, the traveller runs the card through the machine and places their hand into a scanner, which checks that the hand fits the description on the card. If hand and card match, the machine issues an entry pass and opens a gate, allowing the traveller into the country. The whole process takes about 35 seconds, a fraction of the time it now takes immigration officers to process an incoming passenger. Inspass could also improve security against terrorists and other criminals: before admitting a traveller, the machine checks against a database to make sure that he or she has not been barred from entering the country. A group of frequent fliers is putting the system to a year-long test at two airports in the New York area. Immigration officials hope eventually to eliminate the smart card and code the hand-geometry information directly into passports. Similar experiments are due to start soon at airports in Frankfurt and Toronto. To measure the hand’s shape, Inspass uses images from a solid-state television camera which photographs the hand from overhead and from the side. This is translated into a nine-byte code that is recorded on the card. The idea of using the dimensions of various parts of a human body as a means of identification, a technique known as bio-metrics, was explored even before finger-printing came into common use, says Tom Banchoff, a geometry expert at Brown University in Rhode Island. But early efforts failed, possibly because the measurement techniques of the time were not sufficiently detailed, he says. The new system appears to work well. A test in 1991 by researchers at the US Department of Energy’s Sandia National Laboratories showed that the hand geo-metry system made fewer mistakes than identification systems using voiceprints or retinal patterns. The speed and accuracy of the system has attracted the International Air Transport Association, the American Air Transport Association and the World Travel and Tourism Council. They are campaigning for the introduction of a version of the system, known as Future Automated Screening for Travelers, at airports worldwide. ‘If we’re going to speed things up, we have to automate it,
