Biometrics provides a secure method of authentication and identification. Biometric data are difficult to replicate and steal. Unique identifiers include fingerprints, hand geometry, earlobe geometry, retina and iris patterns, voice waves, DNA, and signatures. This paper is based on Periocular biometric recognition, which is the appearance of the region around the eye. Periocular recognition may be useful in applications where it is difficult to obtain a clear picture of an iris for iris biometrics or a complete picture of a face for face biometrics.
