Of all the biometric technologies used for human authentication today, it is generally conceded that Iris recognition is the most accurate and reliable.
Coupling this high confidence authentication with factors like outlier group size, speed, usage/human factors, platform versatility and flexibility for use in identification and verification modes - as well as addressing issues like database size and management concerns - Iris recognition has shown itself to be exceedingly versatile and is suited for large population applications such as airports, universities, and factories.
