New research being released this week at the Black Hat security conference by academics in Spain and the U.S. may make that possible.
The academics have found a way to recreate iris images that match digital iris codes that are stored in databases and used by iris-recognition systems to identify people. The replica images, they say, can trick commercial iris-recognition systems into believing they’re real images and could help someone thwart identification at border crossings or gain entry to secure facilities protected by biometric systems.
The work goes a step beyond previous work on iris-recognition systems. Previously, researchers have been able to create wholly synthetic iris images that had all of the characteristics of real iris images — but weren’t connected to real people. The images were able to trick iris-recognition systems into thinking they were real irises, though they couldn’t be used to impersonate a real person. But this is the first time anyone has essentially reverse-engineered iris codes to create iris images that closely match the eye images of real subjects, creating the possibility of stealing someone’s identity through their iris.
“The idea is to generate the iris image, and once you have the image you can actually print it and show it to the recognition system, and it will say ‘okay, this is the [right] guy,’” says Javier Galbally, who conducted the research with colleagues at the Biometric Recognition Group-ATVS, at the Universidad Autonoma de Madrid, and researchers at West Virginia University.
