Iris Image Reconstruction from Binary Templates

Abstract

This chapter explores the possibility of recovering iris images from binary iris templates. It has been generally assumed that the binary iris code is irreversible, i.e., the original iris texture cannot be derived from it. Here, we discuss two distinct approaches to reconstruct the iris texture from the binary iris code. Next, we discuss a method to detect such synthesized iris textures. Finally, we discuss some of the advantages and risks of generating iris texture from iris codes in the context of data privacy and security.
