Iris scanners can be tricked

Security researchers have discovered a way to replicate a person’s eye to bypass iris–scanning security systems.

A team at the Universidad Autonoma de Madrid was able to recreate the image of an iris from digital codes of real irises stored in security databases.The findings were shared at the annual Black Hat security conference in Las Vegas.It raises doubts over what is considered to be one of the most secure methods of biometric security.

Researcher Javier Galbally and his team, which included researchers from West Virginia University, were able to print out synthetic images of irises.In one experiment, the researchers tested their fake irises against a leading commercial–recognition system. In 80% of attempts, they said, the scanner believed it was a real eye.
