The global rising security concerns propel growth of biometrics recognition techniques. Iris recognition is widely regarded as one of the most promising biometrics methods because of its high accuracy. Among the whole iris recognition process, how to capture the significant features in the iris pattern and to encode them efficiently is a hard task. In this paper, an innovative method is proposed to extract iris features according to iris anatomical structure characteristics. The proposed method can represent the iris pattern with less redundancy and moreover less computational demanding than traditional methods.
