"Stats say aye to ID eye," by Helen Pearson. Nature Science Update, August 8, 2001.

The subject of this cleverly titled article is iris recognition, a technique for identifying oneself by the pattern of the iris. Iris recognition is scheduled to be tested soon at London's Heathrow airport and is envisioned for use at ATMs. Analysis done recently by John Daugman and Cathryn Downing of the University of Cambridge shows that the likelihood of an error when using iris recognition is about one in seven billion. Daugman and Downing's research is published in the article "Epigenetic randomness, complexity and singularity of human iris patterns" in Proceedings of the Royal Society B, Vol. 468.
