PRACTICAL APPLICATION: AN IRIS BIOMETRIC SYSTEM

PRACTICAL APPLICATION: AN IRIS BIOMETRIC SYSTEM

As an example of a biometric user authentication system, we look at an iris biometric system that was developed for use by the United Arab Emirates (UAE) at border control points [DAUG04, TIRO05, NBSP08]. The UAE relies heavily on an outside workforce, and has increasingly become a tourist attraction. Accordingly, relative to its size, the UAE has a very substantial volume of incoming visitors. On a typical day, more than 6,500 passengers enter the UAE via seven international airports, three land ports, and seven sea ports. Handling a large volume of incoming visitors in an efficient and timely manner thus poses a significant security challenge. Of particular concern to the UAE are attempts by expelled persons to re-enter the country. Traditional means of preventing reentry involve identifying individuals by name, date of birth, and other text-based data. The risk is that this information can be changed after expulsion. An individual can arrive with a different passport with a different nationality and changes to other identifying information.

To counter such attempts, the UAE decided on using a biometric identification system and identified the following requirements:

Identify a single person from a large population of people.

Rely on a biometric feature that does not change over time.

Use biometric features that can be acquired quickly.

Be easy to use.

Respond in real-time for mass transit applications.

Be safe and non-invasive.

Scale into the billions of comparisons and maintain top performance. Be affordable.

Iris recognition was chosen as the most efficient and foolproof method. No two irises are alike. There is no correlation between the iris patterns of even identical twins, or the right and left eye of an individual.

System implementation involves enrollment and identity checking. All expelled foreigners are subjected to an iris scan at one of the multiple enrollment centers. This information is merged into one central database. Iris scanners are installed at all 17 air, land, and sea ports into the UAE. An iris-recognition camera takes a black-and-white picture 5 to 24 inches from the eye, depending on the camera. The camera uses non-invasive, near-infrared illumination that is similar to a TV remote control, barely visible and considered extremely safe. The picture first is processed by software that localizes the inner and outer boundaries of the iris, and the eyelid contours, in order to extract just the iris portion. The software creates a so-called phase code for the texture of the iris, similar to a DNA sequence code. The unique features of the iris are captured by this code and can be compared against a large database of scanned irises to make a match. Over a distributed network (see Figure 3.14) the iris codes of all arriving passengers are compared in realtime exhaustively against an enrolled central database.

Note this is computationally a more demanding task than verifying an identity. In this case, the iris pattern of each incoming passenger is compared against the entire database of known patterns to determine if there is a match. Given the current volume of traffic and size of the database, the daily number of iris cross-comparisons is well over 9 billion.

As with any security system, adversaries are always looking for countermeasures. UAE officials had to adopt new security methods to detect if an iris has been dilated with eye drops before scanning. Expatriates who were banned from the UAE started using eye drops in an effort to fool the governments iris recognition system when they try to re-enter the country. A new algorithm and computerized step-by-step procedure has been adopted to help officials determine if an iris is in normal condition or an eye-dilating drop has been used.
