Final answer:
Height is not used for biometric identification because it does not provide the unique, individual specificity that is necessary, unlike fingerprint, iris, or retina patterns.
Step-by-step explanation:
The human characteristic that is NOT used for biometric identification is height. Biometric identifiers are unique, measurable characteristics used to label and describe individuals. While fingerprint, iris, and retina are commonly used in biometric systems due to their unique patterns and features, height is not considered unique enough for individual biometric identification. It cannot provide the high degree of accuracy found in other biometric measures.
