CBP CBP Biometric Standards and Interoperability 2 — Questions and Answers
Question 1: What is the significance of the Interpol FIND (Fingerprint Identification National Database) standard in biometric interoperability?
- It mandates FAR thresholds for border control systems
- It enables member countries to share fingerprint data using a common format (Correct answer)
- It certifies commercial fingerprint sensor vendors
- It defines encryption keys for fingerprint template storage
Correct answer: It enables member countries to share fingerprint data using a common format
Interpol's biometric data exchange framework enables member nations to share fingerprint and other biometric records across jurisdictions using standardized formats.
Question 2: What does 'template aging' refer to in the context of biometric standards and system management?
- The process of archiving old biometric records
- The degradation of biometric template accuracy over time due to natural biological changes (Correct answer)
- The scheduled deletion of templates after a retention period
- The re-encryption of stored templates with updated keys
Correct answer: The degradation of biometric template accuracy over time due to natural biological changes
Template aging refers to the gradual decrease in matching accuracy that occurs as a person's biometric characteristics change over time, causing mismatch with stored templates.
Question 3: In the context of biometric standards, what is a 'biometric reference'?
- A vendor's published performance report
- A stored biometric sample or template used for comparison during verification or identification (Correct answer)
- An academic citation for biometric research
- A hardware calibration baseline for sensors
Correct answer: A stored biometric sample or template used for comparison during verification or identification
A biometric reference is the enrolled biometric data (template or sample) stored in a system against which probe samples are compared during matching.
Question 4: Which NIST publication provides technical guidelines for biometric specifications in PIV credentials?
- NIST SP 800-53
- NIST SP 800-76 (Correct answer)
- NIST SP 800-63
- NIST SP 800-122
Correct answer: NIST SP 800-76
NIST SP 800-76 provides the technical biometric specifications for fingerprint and facial image data included in Personal Identity Verification (PIV) credentials.
Question 5: What does 'interoperability' mean in the context of biometric systems?
- The ability of a single sensor to capture multiple biometric modalities
- The ability of biometric data or systems from different vendors or agencies to work together (Correct answer)
- The cross-training of biometric operators across departments
- The capacity of a biometric system to handle peak enrollment loads
Correct answer: The ability of biometric data or systems from different vendors or agencies to work together
Biometric interoperability is the capability of different systems, products, or agencies to exchange and use biometric data effectively without requiring system-specific customization.
Question 6: What is the purpose of the BioAPI standard (ISO/IEC 19784)?
- To define fingerprint image resolution requirements
- To provide a standardized application programming interface for integrating biometric technologies (Correct answer)
- To regulate biometric data deletion timelines
- To certify biometric matching algorithm accuracy
Correct answer: To provide a standardized application programming interface for integrating biometric technologies
BioAPI (ISO/IEC 19784) defines a standard software interface (API) that allows biometric applications to communicate with different biometric service providers in a vendor-neutral way.
