ISO/IEC 19794-4:2011/COR1:2012 addresses a technical corrigendum to Information technology - Biometric data interchange formats - Part 4: Finger image data - Technical Corrigendum 1, making it relevant where finger image data is being specified, exchanged, or reviewed in biometric workflows. As a supporting document to the parent reference ISO/IEC 19794, it is typically used to correct or clarify the underlying technical text rather than serve as a standalone specification. For engineering teams, laboratories, and procurement reviewers, ISO/IEC 19794-4:2011/COR1:2012 helps ensure that implementation, verification, and documented evaluation are based on the corrected reference.

ISO/IEC 19794-4:2011/COR1:2012 standard overview

This corrigendum is tied to the finger image data portion of the biometric data interchange format series and is intended to modify or refine the published text of the parent document. In practical terms, it supports technical review, conformity assessment, and quality workflows where consistent interpretation of finger image data requirements is important. Organizations working with biometric capture, data exchange, or compliance documentation may use it to confirm that specifications, test evidence, and engineering documentation align with the corrected reference before formal validation or procurement approval.

Applications of ISO/IEC 19794-4:2011/COR1:2012

ISO/IEC 19794-4:2011/COR1:2012 is relevant in biometric systems that handle finger image data, especially where interoperability between devices, software, and downstream systems matters. It may be consulted during product evaluation, laboratory testing, integration work, or regulatory preparation for identity management and access control solutions. The corrigendum can also support documentation reviews in projects that rely on standardized biometric data interchange, helping teams maintain consistent technical assessment practices across capture, storage, exchange, and validation activities.

Why ISO/IEC 19794-4:2011/COR1:2012 matters

Corrective documents like ISO/IEC 19794-4:2011/COR1:2012 matter because small text changes can affect interoperability, compliance workflows, and test outcomes across biometric implementations. Using the corrected reference helps reduce risk during engineering validation, procurement checks, and conformity assessment preparation. It also supports more reliable technical comparison between suppliers and better consistency in quality assurance programs. For organizations managing biometric systems, the corrigendum is a practical compliance reference for ensuring that documentation and implementation decisions reflect the intended corrected requirements.

• Supports correction and clarification of the finger image data part of the biometric interchange format series
• Useful for technical review, verification activities, and documented evaluation of biometric implementations
• Helps align procurement and compliance workflows with the corrected parent reference
• Relevant to interoperability checks, testing consistency, and conformity assessment preparation
