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. State-of-the-Art and Potential MFA Sources

2.1.3. Voice Biometrics

Most of the contemporary smart electronic devices are equipped with a microphone that allows utilizing voice recognition as a factor for MFA. At the same time, the technology advancement of tomorrow may allow special agencies not only to recognize the speakers but also to mimic their voices including the intonation, timbre, etc., which is a serious drawback of utilizing voice as a primary authentication method.
