BIOMETRICS-UNIT-I

Suppose if you are securing access to confidential room. It is type of _______application

• Physical access

• Logical access

• Both Physical access & Logical access

• Difficult to judge

If your Biometric system is not able to authenticate already enrolled user?

You can say that there exists __________in your system

• False Match Rate

• False Non Match Rate

• Failure to Enroll Rate

• Equal Error Rate

Suppose If your Biometric system is not capable of  enrolling some portion of the users ,Then your system is having some :          

• FAR Error

• FNMR Error

• FTE Error

• EER Error

Suppose you were given Biometric database of 100000 users and asked to check existence of duplicate records in the database. Then choosing which of the following  strategy is relevant in this context______________?                                                 

• Verification

• Identification

• Both verification and Identification

• Neither Verification nor Identification

Suppose if you are accessing biometrically enabled ATM.This is _________

type of application

• Physical Access only

• Logical Access only

• Both Physical Access and Logical Access

• NeitherPhysical Access and Logical Access

Which of the following are true related to Verification and Identification?(multiple options possible)

• 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

  ( Signature Scan Keystroke scan)

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)
