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.

4.3. Proposed MFA Solution for V2X Applications

Indeed, our proposed solution may operate out-of-the-box in case where all l factors are present. The system may thus provide a possibility to identify and report any outdated factor information ­– for example, weight fluctuation. Access to a service could be automated when some of the factors are not present. We further elaborate on this feature in the current subsection.
