A review of iris anti-spoofing

To ensure the actual presence of a real legitimate trait in contrast to a fake self-manufactured physical synthetic sample, is a significant problem in biometric authentication, which requires the development of new and efficient protection measures. The whole biometric community, including researchers, developers, standardizing bodies and vendors, has thrown itself into the very challenging task of proposing and developing efficient protection methods against this threat, known as spoofing. The goal of this paper is to provide a comprehensive and structured overview on the work that has been carried out over the last decade in the field of iris anti-spoofing. In brief, the paper has been thought as a tool to provide biometric researchers an overall picture of the current panorama in the mentioned area following a systematic approach.
