Abstract

We discuss methods for generating retina codes from retinal images for biometric user authentication. Starting from the optical disc, concentric circles are placed over the binary vessel image for data sampling and different variants of retina code are generated after transformation to polar coordinates. The methods inter personal variability and robustness is evaluated on the publicly available DRIVE database. Results indicate a low inter personal variability questioning the usefulness of retina codes in sensible authentication systems.
