Abstract: Sclera based recognition is identification of a person using the features of sclera region of the eye. This method allows the use of existing imaging systems to acquire the image of the sclera region and identify people. Assuming that the entire sclera region was enrolled for matching, off-angle eyes reveal more of the sclera vein pattern for matching. This method does not require frontal gaze images a necessary condition. Thus, even an individual who was actively attempting to avoid detection or recognition by looking away from the matching system would be unable to avoid presenting a valid biometric pattern for identification.
