Abstract
Iris recognition is proving to be one of the most reliable biometric traits for personal identification In fact iris patterns have stable invariant and distinctive features for personal identification Reliable authorization and authentication are becoming necessary for many everyday applications Iris recognition has been paid more attention due to its high reliability in personal identification But iris feature extraction is easily affected by some practical factors such as inaccurate localization occlusion and nonlinear elastic deformation The objective of the study and proposed work is to adapt the increasing usage of biometric systems which can reduce the iris preprocessing and describe iris local properties effectively and have encouraging iris recognition performance This work presents an efficient algorithm of iris feature extraction based on modified scale invariant feature transform algorithm SIFT
