Identification Based on Iris Geometric Features

N. Poonguzhali and M. Ezhilarasan

Biometric based authentication system aims to reconstruct the existing token based system. As there is a great need for secured identification in the current information era, it is achieved by biometric features. Iris based recognition system even though is one of the youngest biometric trait for human identification has received a larger impact. Among the various biometric traits, iris has the richest set of information which can be used for human identification. Iris consists of several features such as color, texture feature, macro features and geometric features. In this study, we propose to extract the geometric features based on the pupil, collarette and iris which are used for recognition. This innovative methodology proposes the extraction of geometric information based on the radius, roundness, diameter, roughness, smoothness and other geometric structures of the iris. The results exhibit that these features are discriminating features for identification. This proposed methodology based on geometric features for identification has proven better identification results.
