Multifactor Authentication

Authentication can be accomplished with one factor, two factors, or multiple factors. Which one is the weakest level of authentication and which is the most secure and why? When would a more secure system be required? Be able to explain these multifactor authentication methods: password protection, token presence, voice biometrics, facial recognition, ocular-based methodology, hand geometry, vein recognition, fingerprint scanner, thermal image recognition, and geographical location. What are some challenges of multiple factor authentication when using biometrics? There is a lot of interesting information covered in this article that you do not need to memorize, but that you should be aware of.

2.1.7. Vein Recognition

The advances in fingerprint scanners offer an opportunity to collect the vein picture of the finger as well. More complicated devices utilize palm print recognition to acquire and store the shape/movement of the entire hand. At the current stage of development, vein biometrics are still vulnerable to spoofing attacks.
