Abstract: Iris recognition is a well-studied biometric technique that is both reliable and convenient. The paper focuses on the hypothesis that due to the rich structure of the iris data, a portion of the iris data could render results comparable to those achieved by processing the full data. Experiments are conducted on partial iris data using Daugman|s algorithm. Using the phase orientation of Daugman|s algorithm, only half of the iris data was examined in a series of tests. Identical irises were identified using partial data in most cases. For those cases that a match could not be found, the similarity score for identical irises was still significantly higher than that for different irises. The results support the promise of making the iris recognition a covert technique with many applications in security.
