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.

2.2.5. Electroencephalographic (EEG) Recognition

his solution is based on the brain waves analysis and could be considered from the fundamental philosophical proposition "Cogito ergo sum" by R. Descartes, or "I think, therefore I am". It allows for obtaining a unique sample of the person's brain activity pattern. Formerly, EEG data capture could have been performed only in clinical settings by using invasive probes under the skull or wet-gel electrodes arrayed over the scalp. Today, the simple EEG collection is possible by utilizing market-available devices having the size of a headset.
