Biometrics allows for unique features such as _____ to be used for identification and verification.

Biometrics utilizes unique physical or behavioral characteristics to identify and verify individuals, and fingerprints are one of the most widely recognized forms of biometric identification. Each person's fingerprints have distinct patterns and ridges that are unique to them, making it a reliable method for confirming identity. The use of fingerprints is deeply rooted in security systems due to their uniqueness and permanence, as they do not change significantly over time. This method is commonly employed in various security applications, from access control systems to personal devices.

While the other biometric methods like voice recognition, retinal scans, and facial recognition also serve as effective means of identification and verification, fingerprints remain one of the most established and commonly utilized techniques in the field of electronic security. Their ease of use and the relative speed of analysis further contribute to their popularity in security solutions.
