Which of the following is a method of biometric identification?

• A. Username and password
• B. Digital tokens
• C. Facial recognition scans
• D. Email authentication

Answer: (C)

Facial recognition scans are a method of biometric identification because they utilize unique physical characteristics of an individual to verify their identity. Biometric systems analyze features such as the distance between the eyes, the shape of the nose, and other facial landmarks to create a unique map of a person’s face. This method not only provides a high level of accuracy but also enhances security, as it is difficult to replicate someone's facial features. In contrast, username and password, digital tokens, and email authentication are all examples of knowledge-based or possession-based identification methods, which rely on what a user knows or has rather than on their physical characteristics. These methods can be less secure as they are often vulnerable to phishing and credential theft.
