Biometric System

Biometric System

Biometric verification is any means by which a person can be uniquely identified by evaluating one or more distinguishing biological traits. Unique identifiers include fingerprints, hand geometry, earlobe geometry, retina and iris patterns, voice waves, DNA, and signatures.

Biometric Performance:

  • False match rate(FMR, also called FAR = False Accept Rate).
  • Timer: Wake timer / Sleep timer.
  • False non-match rate (FNMR, also called FRR = False Reject Rate).
  • Receiver operating characteristic or relative operating characteristic (ROC).
  • Equal error rate or crossover error rate (EER or CER).
  • Failure to enroll rate (FTE or FER).
  • Failure to capture rate (FTC).
  • Template capacity.
