An improved algorithm for efficient iris based system

Nowadays, many applications require authentication to identify human before giving access to the resources. With new advances in technology, biometric technique of human authentication, which uses the human iris pattern, is well suited. Biometrics intends to identify a user by his/her physical and or/ behavioural characteristics. Among all biometric techniques, Iris recognition stands out as its error rates are lowest. Iris recognition includes eye imaging, localization, normalization, verification etc. This paper presents an overview of the fundamentals of biometric identification and tries to find out the effect of masking the normalized iris image on recognition rates.
