For almost twenty years, the iris recognition research field has been hampered because of a broad patent covering it. As this patent recently expired, many teams around the world are again working on new technologies in this field. Iris recognition is in fact seen as the most accurate biometric recognition technology because no two irises are identical. And researchers at the University of Bath in England have developed new computer algorithms which are 100 per cent accurate in initial trials. Now the researchers are putting online a database of 16,000 iris images collected mainly from students. The source code is also available if you want to further improve the algorithms.
