ISO/IEC 19795-1:2021

Overview - ISO/IEC 19795-1:2021 (Biometric performance testing and reporting)

ISO/IEC 19795-1:2021 establishes the principles and framework for empirical biometric performance testing and reporting. The standard defines how to measure and report biometric system performance in terms of error rates and throughput rates, prescribes required performance metrics, and sets requirements for data recording, test protocols, and test reporting. It is intended for testing based on system outputs (comparison scores and decisions) without requiring access to internal algorithms or population distributions. The standard does not cover deliberate attacks (e.g., presentation attacks).

Key technical topics and requirements

• General biometric system model: conceptual components and functions (data capture, transmission, signal processing, storage, comparison, decision, administration, external interfaces).
• Performance metrics: definitions and measurement requirements for error rates and throughput, including:
  • Failure‑to‑enrol and failure‑to‑acquire rates
  • False Match Rate (FMR) / False Accept Rate (FAR)
  • False Non‑Match Rate (FNMR) / False Reject Rate (FRR)
  • Identification metrics (false‑positive/false‑negative identification rates, selectivity)
  • Transaction durations and computational workload
• Test planning: guidance on test subject selection, sample sizes, controlling factors that influence performance, and avoiding bias in data collection.
• Data collection and protocols: required metadata, enrolment/verification/identification trial design, online/offline comparisons, handling of enrolment failures and data-entry errors.
• Analysis and reporting: methods for score distribution visualization, detection error trade‑off (DET), uncertainty estimation, longitudinal and pairwise analyses, and clear reporting to aid reproducibility and comparability.

Practical applications and who uses it

ISO/IEC 19795-1 is used by:

• Test laboratories and independent evaluation centres conducting biometric performance assessments.
• Biometric vendors and system integrators validating product claims and optimizing systems.
• Procurement teams and system architects specifying performance requirements and acceptance tests.
• Researchers and academics performing empirical studies and comparisons of biometric algorithms.
• Regulators and certification bodies setting conformity evaluation procedures.

Practical uses include benchmarking systems, predicting field performance, comparing products, verifying contractual performance requirements, and producing transparent, bias‑aware test reports.
