Which of the following best describes biometrics?

The chosen answer accurately describes biometrics as it refers to a method of verifying an individual's identity based on unique physical characteristics. These characteristics can include fingerprints, facial recognition, iris patterns, and voice recognition, all of which are distinct to each individual and difficult to replicate. This reliance on physical traits makes biometrics a secure form of identity validation, often employed in various technologies for authentication purposes.

By focusing on aspects such as security and identity verification, biometrics significantly enhances the reliability of systems requiring user authentication, especially when compared to traditional methods like passwords, which can be forgotten, stolen, or easily compromised. This distinction underlines the increasing adoption of biometric systems in electronic transactions and access control, affirming their critical role in enhancing security for both individuals and organizations.
