Iris recognition is considered as one of the best biometric method used for human identification and verification. The performance of biometric system based on iris recognition depends on the selection of iris features. In this paper, Gray Level Co-occurrence Matrix (GLCM) method is used for extracting the texture. The GLCM is a statistical method that includes local features like contrast, correlation, energy, homogeneity and entropy. The proposed approach comprises of five main steps: image acquisition, Challenge Response Test (CRT), pre-processing, texture extraction and matching.
