What is a biometric access control method primarily based on?

A biometric access control method is primarily based on unique biological traits. This approach utilizes distinctive characteristics of individuals, such as fingerprints, facial recognition, iris patterns, or voice recognition to verify identity and grant access. Biometric systems are designed to analyze and compare these biological traits against stored data to ensure that only authorized users can gain entry.

The reliance on unique biological traits is key, as they offer a high level of security. Unlike physical keys or numerical codes, which can be lost, stolen, or guessed, biometric traits are inherently tied to the individual, making them much harder to replicate or distribute without authentication. The use of biometrics enhances safety and security by ensuring that access is granted solely based on the individual's unique biological identifiers.
