Iris Recognition Immigration System

Last updated

Iris Recognition Immigration System (IRIS) was an initiative, launched in 2004, to provide automated clearance through UK immigration for certain frequent travellers. It functioned in "one-to-all" identification mode, searching a large database of some million enrolled frequent travellers to see if anyone matched the presenting iris. The passenger was not asked to assert any identity, e.g. by presenting a Passport or ID card which would then require only a "one-to-one" verification test against that single enrolled identity. Thus IRIS exploited the great robustness of iris recognition against making False Matches, since (unlike weak biometrics such as face recognition) it could survive the vast number of opportunities to make False Matches when searching a large database, instead of only needing to test just a single asserted identity. It was decommissioned in September 2013 in favour of e-passport entry using biometric data stored on the e-passport chip, which requires only a single asserted identity to be tested and thus could function using weaker biometrics in the simple "one-to-one" verification mode.

Contents

IRIS relied on biometric technology to authenticate identity and was part of the e-borders initiative of the UK Government. The main factor behind the decision to decommission IRIS was the cost of staffing the enrolment offices in airport terminals, whereas face recognition only required submitting a Passport-type photograph acquired in a photo-booth without the need for personal presentation to airport enrolment staff.

The entire scheme, including cost of scrappage, cost £11.8 million. [1]

Procedure

Enrolled passengers could enter the UK through a special automated immigration control barrier incorporating an iris recognition camera. These barriers were located in certain Immigration Arrival Halls and form part of Immigration and Passport Control.

Availability

Enrolment took place in the airport departure lounge where an Immigration Officer assesses eligibility and enrols qualifying persons. Those who qualified to participate in the scheme had both their eyes photographed in order to capture their iris patterns. This data was then stored securely alongside their personal details.

Originally IRIS was rolled out at London Heathrow, London Gatwick, Birmingham and Manchester in 2004 for an intended deployment period of five years. [2] As of February 2013, IRIS was only available at Heathrow Terminals 3 and 5, [3] all other barriers being decommissioned. These last operational barriers were decommissioned on 15 and 16 September 2013, respectively, after the original deployment plan for five years had been doubled to nearly ten years. [4]

    <span class="mw-page-title-main">SmartGate</span>

    SmartGate is an automated self-service border control system operated by the Australian Border Force and New Zealand Customs Service and located at immigration checkpoints in departure and arrival halls in ten Australian international airports, and 4 New Zealand international airports. SmartGates allow Australian ePassport holders and ePassport holders of a number of other countries to clear immigration controls more rapidly, and to enhance travel security by performing passport control checks electronically. SmartGate uses facial recognition technology to verify the traveller's identity against the data stored in the chip in their biometric passport, as well as checking against immigration databases. To use the SmartGate system, the traveller must have a biometric passport from Australia, New Zealand or certain other countries. The ePassport gate scanner reads all the information contained in the chip inside the passport and runs the data against numerous databases to determine if the traveller is a security risk, while a camera takes a picture of the traveller and an officer at a control station behind the gates checks that the image captured by the camera matches the one on the passport. Once the data verification and facial recognition process is complete, doors will automatically either open, signifying that the traveller is permitted to enter and/or exit the country, or remain closed and a stop icon illuminate, demonstrating that the traveller has failed the security checks and will personally meet with immigration officials.

    <span class="mw-page-title-main">Automated border control system</span> Type of automated self-service barrier

    Automated border control systems (ABC) or eGates are automated self-service barriers which use data stored in a chip in biometric passports along with a photo or fingerprint taken at the time of entering the eGates to verify the passport holder's identity. Travellers undergo biometric verification using facial or iris recognition, fingerprints, or a combination of modalities. After the identification process is complete and the passport holder's identity is verified, a physical barrier such as a gate or turnstile opens to permit passage. If the passport holder's identification is not verified or if the system malfunctions, then the gate or turnstile does not open and an immigration officer will meet the person. E-gates came about in the mid-2000s as an automated method of reading the then-newly ICAO mandated e-passports.
