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.

2.1.5. Ocular-Based Methodology

The iris recognition techniques are on the market for more than 20 years. This approach does not require the user to be close to the capture device while analyzing the color pattern of the human eye. Retina analysis is another attractive technique. Here, a thin tissue composed of neural cells that are located in the posterior portion of the eye is captured and analyzed. Because of the complex structure of the capillaries that supply the retina with blood, each person’s retina is unique. The most prominent challenges in those methods are the need for high quality capture device and robust mathematical technique to analyze the image.
