Eye-scan security check 'can work'
Mathematicians have confirmed that scanning human eyes can become a risk-free security device in the future. A new study shows iris recognition is almost error-proof because the chances of getting a matching pattern when comparing two images is as low as one in seven billion.
Even identical twins and the left and right eyes of the same person have iris 'barcodes' as different as unrelated eyes. John Daugman and Cathryn Downing, of the University of Cambridge, carried out the most extensive ever comparison of iris pictures reports.
More than two million irises were examined before the mathematicians decided each one was unique and could be used as a security check. One iris-based security system is already be prepared for trials at Heathrow Airport. The new study findings are published in the journal Proceedings of the Royal Society: Biological Sciences Series B and reported in the journal Nature.
