Retina Identification

Abstract

Retina based identification is perceived as the most secure method of authenticating an identity. This chapter traces the basis of retina based identification and overviews evolution of retina based identification technology. It presents details of the innovations involved in overcoming the challenges related to imaging retina and user interface. The retinal information used for distinguishing individuals and a processing method for extracting an invariant representation of such information from an image of retina are also discussed. The issues involved in verifying and identifying an individual identity are presented. The chapter describes performance of retina based identification and the source of inaccuracies thereof The limitations of the retina based technology are enumerated. Finally, the chapter attempts to speculate on the future of the technology and potential applications.
