But these systems are not reliable enough for many environments, due to their common inability to differentiate between a true authorized user and an user who fraudulently acquired the privilege of the authorized user. A solution to these problems has been found in the biometric based authentication technologies. A novel fully-automatic authentication system is proposed using the retinal vessel tree pattern as biometric characteristic. The goal is to develop a robust biometric template extraction and matching methodology capable of dealing with a more heterogeneous scenario than before. The experimental results show that the authentication method is capable of...
