A biometric system provides automatic identification of an individual based on a unique feature or characteristic possessed by the individual. Iris recognition is regarded as the most reliable and accurate biometric identification system available. Most commercial iris recognition systems use patented algorithms developed by a researcher, and these algorithms are able to produce perfect recognition rates but not includes time requirement in account. However, published results have usually been produced under favorable conditions, and there have been no independent trials of the technology.
