Biometrics

DEFINITION:

The measurement, analysis, identification, verification, classification, or recognition of individuals through biological, physiological, or behavioral characteristics that can distinguish one person from another.

FUNCTION:

Transforms human characteristics into measurable identifiers that can be used for recognition, authentication, tracking, verification, classification, or monitoring.

EXAMPLES:

  • Fingerprint recognition
  • Facial recognition
  • Iris scanning
  • Retina scanning
  • Voice recognition
  • Gait analysis
  • Hand geometry recognition

NOTES:

Biometric systems may use physical characteristics, behavioral patterns, or combinations of both. Their effectiveness depends upon measurement quality, matching algorithms, database accuracy, environmental conditions, and verification thresholds.

CONTROL TEXT OBSERVATION:

Names can be changed, documents can be replaced, and credentials can be transferred. Biometrics function as an identity-binding mechanism that links observation directly to physical or behavioral characteristics of an individual. Through biometrics, identity becomes measurable, recognition becomes automated, and tracking can persist across systems, locations, and time.
