Verification is a one -to-one matching
Identification is a one-to-n matching
Verification is a one -to-n matching
Identification is a one-to-one matching
Which of the following matching is appropriate?(multiple options possible)
Physiological Biometrics
(Finger Scan, Iris Scan)
Behavioural Biometrics
(Signature Scan, Keystroke scan)
Behavioural Biometrics
( Finger Scan, Iris Scan)
Physiological Biometrics

Which of the following is not true related to Biometric template?
Templates are proprietary to each vendor and each technology
There is no common biometric template format
Biometric data such as fingerprints and facial images cannot be reconstructed from biometric templates
Same templates are generated every time a user presents biometric data
Probability that a user’s template will be incorrectly judged to be a match for a different user’s template. is called as:
FMR(False Match Rate)
FMR(False Match Rate)
FTE(Failure to Enroll Rate)
EER(Equal Error Rate)
Which of the following best matches ATV(Ability to Verify Rate)
ATV = (1 - FTE)(1- FNMR)
ATV = (1 - FMR)(1- FNMR)
ATV = (1 - FMR)(1- FTE)
ATV = (1 - EER)(1- FMR)
