Biometric authentication systems based on hand pattern vein, digital certificates and smart cards

This paper describes and implements an authentication solution using biometrics, digital certificates and smartcards to solve the security problems in the authentication process. The first part is a general introduction to the topic, the second is s brief overview about using biometrics, more exactly hand vein pattern, the third part presents a method of extracting the pattern vein of the back of the hand also how to match two templates. The fourth part presents the two necessary phases in any authentication system: the enrollment and the authentication. A proposed authentication protocol is described too. The fifth part generalize the possible attacks and vulnerabilities in a biometric authentication system and it also shows how our system is able to avoid them. The sixth part talks about the implementation of the application. Finally, in the conclusion, we tried to summarize our work and prove the benefits of using this system.
