dc.description.abstractThis work investigates the feasibility of using the dynamic features of the eyes for biometric identification. Identifying individuals using eye movements is typically limited by a low accuracy, thus preventing this technique from becoming commercially viable. In addition, the human eyes constitute a rich source of information, still only partially understood so far, hence more research is needed to understand exactly what kind of information they can provide, and what technique should be applied to analyze such information. It is also largely unknown what kind of feature will yield accurate data most useful to biometric identification, or which stimuli most influence most the dynamic features of the eyes and their usability as a biometrical trait. We show that, by combining eye movement features and iris constriction and dilation parameters, the dynamic features of the eye can yield a good level of accuracy for biometric systems. The approach consists of recording and categorizing eye movements as well as changes in pupil size into segments consisting of saccades and fixations, and computing for each the many velocity and acceleration features that are used to train the classifier to perform the biometric identification. We tested four types of stimuli to hypothesize which will provide a viable stimulating method for extracting eye features. The results suggest that simple stimuli such as images and graphs can appropriately excite the dynamic features of the eye for the purpose of biometric identification.en_US
