Which technology identifies individuals using physiological traits?

Biometrics is the technology that uses physiological traits to identify individuals. This can include features such as fingerprints, facial recognition, iris patterns, and even voice recognition. The fundamental idea behind biometrics is that these unique physical characteristics can serve as reliable indicators of identity, making them a prominent choice for security and access control systems.

For instance, when a fingerprint scanner reads the characteristics of a fingerprint, it compares them against stored biometric data to authenticate a user. This high degree of accuracy and reliability in identifying individuals based on inherent physical traits distinguishes biometrics from other identification methods that rely on something a user knows (like passwords) or possesses (like a keycard or ID).

In contrast, password security relies on users remembering complex strings of characters, which can be compromised through theft or forgetting. Remote access control generally refers to technologies that allow access to systems or networks from remote locations, often using various authentication methods, but it doesn’t specifically focus on using physiological traits. Encryption is a method of securing data by converting it into a code to prevent unauthorized access but does not relate to individual identification per se.
