ISO/IEC 19795-2:2007 PDF

Overview

ISO/IEC 19795-2:2007 defines standardized methodologies for biometric performance testing and reporting, focusing on the two primary evaluation types used across biometric systems: technology evaluation and scenario evaluation. It builds on the principles in Part 1 and provides requirements and recommendations for protocol development, data collection, analysis and reporting so results are meaningful, repeatable and comparable.

• Technology evaluation: offline testing of enrolment and comparison algorithms using pre‑collected corpuses to generate large volumes of comparison scores and candidate lists indicative of an algorithm’s discriminating power.
• Scenario evaluation: online or real‑time testing that includes sensors, system behavior and Test Subject - system interactions to measure performance in modeled environments.

Key topics and requirements

ISO/IEC 19795-2:2007 prescribes the structure and content of biometric tests and reports, including:

• Test protocol development: full description of test objectives, environments, population characteristics and procedures.
• Test design: guidance on selecting technology vs scenario methodologies and tailoring tests for identification or verification use-cases.
• Data collection and corpuses: requirements for assembling appropriate sample corpuses for technology tests and for real‑time sample capture in scenario tests.
• Performance measurement: standardized metrics and measurement processes (e.g., failure‑at‑source, false match/non‑match considerations) to ensure repeatability and comparability.
• Execution and reporting: template-style expectations for reporting methods, results, and assumptions so stakeholders can interpret outcomes reliably.
• Test crew, fairness and legal considerations: roles, human factors (effort, habituation), fairness expectations, release of source code and supplier comment procedures.
• Conformance rules: evaluation conformance differs by methodology (technology vs scenario) and comparison type (identification vs verification).

Applications and who uses it

ISO/IEC 19795-2 is practical for organizations involved in biometric performance testing, including:

• Biometric system developers and algorithm researchers - to benchmark algorithms using standardized technology evaluation methods.
• System integrators and vendors - to validate sensors and end-to-end systems via scenario evaluations.
• Test laboratories and certification bodies - to design repeatable test protocols and produce comparable reports.
• Deployers and procurement teams - to evaluate candidate systems under representative operational scenarios.
• Academics and R&D groups - for reproducible experimental design and cross-algorithm comparisons.
