ISO/IEC 19794-5:2011/Amd 1:2014 PDF

Overview

ISO/IEC 19794-5:2011/Amd 1:2014 is an important international standard in the field of information technology for biometric data interchange, focusing specifically on face image data. This amendment introduces a defined conformance testing methodology and clarifications around defects, helping organizations ensure that the creation, transmission, and interpretation of face image data files are interoperable and robust.

Published jointly by ISO and IEC, the amendment enhances consistency and reliability for biometric systems and products that utilize face image data, ensuring global interoperability and clear criteria for compliance.

Key Topics

• Biometric data interchange formats: The standard specifies formats for encoding, storing, and sharing face image data.
• Conformance testing methodology: Clear steps, test assertions, and procedures are introduced for verifying compliance at different levels:
  • Structure of face image data format (Type A Level 1)
  • Internal consistency of data within each field (Type A Level 2)
  • Semantic correctness of data (Type A Level 3)
• Clarification of defects: The amendment addresses certain inconsistencies and ambiguities observed in prior editions, improving clarity for implementers.
• Anthropometric landmarks: Definitions and codification for consistent identification of facial features and landmarks.
• Data fields and encoding requirements: Details around encoding angles, feature points, and other biometric attributes using standardized structures.
• Exclusion of non-conformance tests: The methodology does not cover biometric product performance, robustness, security, or acceptance testing.

Applications

Organizations and solution providers apply ISO/IEC 19794-5:2011/Amd 1:2014 in several practical scenarios, including:

• Border control and law enforcement: Ensuring face image data captured and stored by various national agencies complies with interoperable standards, enabling smooth data exchange between countries.
• Government identity programs: National ID, passport, or driver’s license programs use the standard for reliable face image acquisition and verification.
• Biometric authentication systems: Banks, travel, healthcare, and access control systems depend on accurate and interoperable face biometric records.
• Vendor product development: Biometric software and device manufacturers use the conformance testing methodology to prove their products’ compliance, simplifying certification and market acceptance.
• Testing and certification laboratories: Third-party labs can employ the documented test assertions and procedures to conduct neutral and reproducible conformance assessments.

These use cases benefit from the amendment's clearer requirements for encoding face image data, documenting anthropometric reference points, and performing neutrality-assured conformance testing.
