CBP CBP Biometric Standards and Interoperability 1 — Questions and Answers
Question 1: What is the primary purpose of the ISO/IEC 19794 series of standards in biometrics?
- To define biometric sensor hardware specifications
- To standardize biometric data interchange formats for interoperability (Correct answer)
- To regulate privacy laws for biometric data
- To certify biometric system vendors
Correct answer: To standardize biometric data interchange formats for interoperability
ISO/IEC 19794 defines standardized data formats for exchanging biometric information (fingerprints, face, iris, etc.) between systems from different vendors.
Question 2: Which U.S. standard defines the data format for electronic fingerprint transmission used by law enforcement agencies?
- ISO 19794-4
- ANSI/NIST-ITL 1-2011 (Correct answer)
- FIPS 201
- PIV-I
Correct answer: ANSI/NIST-ITL 1-2011
ANSI/NIST-ITL 1-2011 (and its updates) defines the standard data format for exchanging fingerprint, facial, and other biometric data among U.S. law enforcement agencies.
Question 3: What does the FIPS 201 standard govern in U.S. government biometric deployments?
- Biometric performance testing requirements
- Personal Identity Verification (PIV) credentials for federal employees (Correct answer)
- Encryption standards for biometric databases
- Fingerprint sensor hardware certification
Correct answer: Personal Identity Verification (PIV) credentials for federal employees
FIPS 201 establishes the requirements for the Personal Identity Verification (PIV) system used by U.S. federal employees and contractors, including biometric components.
Question 4: In biometric interoperability, what does 'conformance testing' verify?
- That a system meets performance benchmarks for FAR/FRR
- That biometric data formats and system behaviors comply with specified standards (Correct answer)
- That biometric sensors are physically durable
- That enrolled templates are encrypted at rest
Correct answer: That biometric data formats and system behaviors comply with specified standards
Conformance testing verifies that a biometric system correctly implements the data formats, interfaces, and behaviors specified in applicable standards.
Question 5: What is the role of the Common Biometric Exchange Formats Framework (CBEFF)?
- To provide a universal wrapper format for encapsulating biometric data from any modality (Correct answer)
- To define sensor hardware requirements for fingerprint scanners
- To regulate the retention period for biometric templates
- To score vendor performance in government procurements
Correct answer: To provide a universal wrapper format for encapsulating biometric data from any modality
CBEFF (defined in ISO/IEC 19785) provides a standardized wrapper structure for packaging biometric data of any type, including metadata about the data's format and origin.
Question 6: Which international standard specifically addresses biometric sample quality requirements?
- ISO/IEC 29794 (Correct answer)
- ISO/IEC 19785
- NIST SP 800-76
- IEEE 2410
Correct answer: ISO/IEC 29794
ISO/IEC 29794 is the international standard series for biometric sample quality, defining metrics and algorithms for assessing the quality of biometric samples.
