Mixed Deck — All CBP Topics Flashcards

What is a key requirement for biometric data compliance under GDPR?

Answer: Obtaining explicit consent from users

The General Data Protection Regulation (GDPR) requires obtaining explicit user consent before collecting and processing biometric data.

What is the purpose of biometric data hashing?

Answer: To enhance security by making data irreversible

Hashing biometric data converts it into a fixed-length value that cannot be reversed, improving security and reducing privacy risks.

What is the primary advantage of iris recognition compared to other biometric methods?

Answer: Higher accuracy and resistance to spoofing

Iris recognition provides high accuracy and is less prone to spoofing due to the complexity of iris patterns.

Which NIST standard specifies the Personal Identity Verification (PIV) card and biometric requirements for US federal employees?

Answer: FIPS 201

FIPS 201 (Federal Information Processing Standard 201) specifies the PIV system, including biometric requirements for US federal employees.

In biometric evaluation, what is an 'operational evaluation'?

Answer: Testing conducted in a live, real-world deployment environment

An operational evaluation tests a biometric system in its actual deployment environment with real users under live conditions.

What does the term 'BIR' stand for in the context of CBEFF (ISO/IEC 19785)?

Answer: Biometric Information Record

BIR stands for Biometric Information Record, the data structure defined by CBEFF that contains biometric data along with associated metadata.

What does the 'Failure to Enroll' (FTE) rate measure?

Answer: The proportion of individuals whose biometric samples cannot be successfully enrolled

FTE (Failure to Enroll) rate measures the proportion of users for whom the system cannot create a usable biometric template during the enrollment process.

What is the primary concern when storing biometric data?

Answer: Preventing unauthorized access and identity theft

Biometric data must be securely stored to prevent unauthorized access, identity theft, and misuse.

What does throughput rate measure in biometric system testing?

Answer: The number of individuals processed per unit of time

Throughput rate measures how many individuals a biometric system can process (enroll or verify) within a defined time period.

What is the recommended frequency for reviewing and updating biometric technologies and modalities protocols?

Answer: Monitoring outcomes through regular data collection and trend analysis

Monitoring outcomes through regular data collection and trend analysis is the correct approach because effective biometric technologies and modalities in the biometrics professional field requires adherence to professional standards, evidence-based practices, and systematic methodology. This approach ensures consistent, high-quality outcomes while maintaining professional accountability.

What does 'decidability index' (d-prime) measure in biometric system analysis?

Answer: The separation between genuine and impostor score distributions

The decidability index (d') quantifies how well a biometric system separates genuine match scores from impostor scores — higher values indicate better discrimination.

What does the False Acceptance Rate (FAR) measure in a biometric system?

Answer: The rate at which imposters are incorrectly accepted

FAR measures the frequency with which unauthorized individuals are incorrectly accepted by the biometric system.

Which ethical concern is associated with the use of biometric identification?

Answer: Privacy risks and data misuse

Privacy is a major ethical concern, as biometric data is personal and sensitive, requiring strict protection against misuse.

A new regulation impacts biometric system implementation and integration procedures. What should a CBP professional do first?

Answer: Ensuring compliance with current regulatory requirements and standards

Ensuring compliance with current regulatory requirements and standards is the correct approach because effective biometric system implementation and integration in the biometrics professional field requires adherence to professional standards, evidence-based practices, and systematic methodology. This approach ensures consistent, high-quality outcomes while maintaining professional accountability.

Which tool or methodology is most appropriate for analyzing biometric system implementation and integration outcomes?

Answer: Maintaining professional boundaries while building collaborative relationships

Maintaining professional boundaries while building collaborative relationships is the correct approach because effective biometric system implementation and integration in the biometrics professional field requires adherence to professional standards, evidence-based practices, and systematic methodology. This approach ensures consistent, high-quality outcomes while maintaining professional accountability.

Which NIST publication provides technical guidelines for biometric specifications in PIV credentials?

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.

Which scenario would require a biometrics professional professional to escalate a biometric technologies and modalities concern?

Answer: Creating feedback mechanisms that encourage continuous improvement

Creating feedback mechanisms that encourage continuous improvement is the correct approach because effective biometric technologies and modalities in the biometrics professional field requires adherence to professional standards, evidence-based practices, and systematic methodology. This approach ensures consistent, high-quality outcomes while maintaining professional accountability.

What is the main challenge of using gait recognition as a biometric modality?

Answer: Can be affected by footwear and injuries

Gait recognition can be affected by factors such as footwear, injuries, and walking surfaces, making it less consistent.

What is the recommended approach to protect biometric data from breaches?

Answer: Encrypting biometric data for security

Encrypting biometric data ensures that even if a data breach occurs, the information remains unreadable to unauthorized parties.

What encoding format is mandated by ICAO for the primary biometric (facial image) stored in e-passports?

Answer: JPEG2000 or JPEG

ICAO mandates JPEG or JPEG2000 encoding for facial images stored on e-passport chips, with JPEG2000 preferred for better compression.
