Question
A company requires employees to use a fingerprint scan before accessing sensitive company data. What type of authentication is this?
A. Biometric authentication
B. Token-based authentication
C. Single sign-on (SSO)
D. Password-based authentication
E. Two-factor authentication
Answer
A. Biometric authentication
Explanation
Fingerprint scanning is a form of biometric authentication, which verifies identity based on physical characteristics.
Requiring employees to use a fingerprint scan before accessing sensitive company data is an example of biometric authentication.
Biometric authentication verifies identity using unique physical characteristics, such as fingerprints, facial features, iris patterns, or voiceprints.
Fingerprint scanning is one of the most widely implemented biometric methods due to its accuracy, convenience, and the uniqueness of each individual’s fingerprint.
When a user enrolls, their fingerprint is scanned and converted into a mathematical template, which is securely stored. Upon subsequent access attempts, the system compares the live scan to the stored template to grant or deny access.
This method falls under the “something you are” authentication factor, making it inherently more secure than knowledge-based methods like passwords, which can be guessed or stolen.
Biometric authentication is commonly used for high-security environments and is increasingly integrated into everyday devices, including smartphones, laptops, and access control systems.
Fingerprint scanning authenticates users based on unique physical characteristics, providing a secure and user-friendly method for controlling access to sensitive company data.
