ISO/IEC 19784-4:2011/COR1:2013 is a technical corrigendum linked to the biometric application programming interface series, specifically the Biometric Sensor Function Provider Interface. It serves as a supporting correction to the parent document, helping ensure that the referenced interface description is interpreted and implemented consistently. For engineering teams, software integrators, and compliance reviewers, ISO/IEC 19784-4:2011/COR1:2013 matters because even small editorial or technical corrections can affect integration accuracy, verification activities, and documented evaluation within biometric system workflows.

ISO/IEC 19784-4:2011/COR1:2013 standard overview

This corrigendum is associated with ISO/IEC 19784-4, which addresses the biometric sensor function provider interface within the broader biometric application programming interface framework. As a corrigendum, it is not a standalone technical specification, but a modifying reference intended to correct or clarify the published text of the parent part. That makes it relevant during technical review, implementation validation, and conformity assessment preparation, especially where precise interface behavior, terminology, or referenced requirements affect interoperability and operational consistency.

Applications of ISO/IEC 19784-4:2011/COR1:2013

Organizations may use ISO/IEC 19784-4:2011/COR1:2013 when maintaining or reviewing biometric software interfaces, sensor integration work, or supplier documentation tied to biometric capture functions. It can be useful in product evaluation, laboratory evaluation, and quality workflows where the interface between applications and biometric sensors must be checked against the parent technical document. Procurement teams and compliance specialists may also reference it when confirming that implementation documents, test plans, and regulatory preparation materials reflect the corrected wording.

Why ISO/IEC 19784-4:2011/COR1:2013 matters

In biometric systems, even a corrigendum can influence how requirements are understood and applied. ISO/IEC 19784-4:2011/COR1:2013 supports risk management by reducing ambiguity in interface interpretation and helping teams align technical documentation with the corrected text. That can improve testing consistency, technical validation, and procurement review decisions. For organizations preparing conformity assessment evidence, using the corrected reference may also help avoid mismatches between engineering documentation, implementation details, and verification results.

Practical focus areas

• Correction reference for the biometric sensor function provider interface defined in the ISO/IEC 19784 series
• Useful during implementation review and verification of biometric application programming interface behavior
• Supports consistency in test planning, technical assessment, and compliance documentation
• Relevant where corrective text may affect interoperability or interpretation of the parent document
