ISO/IEC 19794-4:2005/COR1:2011 is a technical corrigendum connected to the finger image data profile in the ISO/IEC 19794 series. It is relevant when teams need to review or maintain biometric data interchange documentation for fingerprint-based systems, especially where accurate reference material supports technical validation, procurement checks, or conformity assessment. Because it modifies the parent document rather than replacing it, the reference is most useful for organizations that rely on consistent interpretation of finger image data requirements and want to reduce errors in engineering documentation and compliance workflows.

What is ISO/IEC 19794-4:2005/COR1:2011?

ISO/IEC 19794-4:2005/COR1:2011 is a corrigendum to Information technology - Biometric data interchange formats - Part 4: Finger image data - Technical Corrigendum 1. As a supporting document, it is intended to correct or clarify the parent specification for finger image data interchange rather than stand alone as a full technical requirement set. In practice, it helps engineers, laboratories, and compliance teams align technical review activities with the revised wording so that documented evaluation, interoperability checks, and technical validation are based on the most accurate reference.

Applications of ISO/IEC 19794-4:2005/COR1:2011

This corrigendum is typically used in workflows involving biometric systems that capture, store, exchange, or verify fingerprint image data. It may be consulted during product evaluation, software integration, laboratory testing, or conformity assessment preparation where finger image records must follow the parent format consistently. Procurement and compliance teams may also use it to confirm that a supplier’s engineering documentation reflects the corrected reference. ISO/IEC 19794-4:2005/COR1:2011 is most relevant where biometric data interchange, operational consistency, and technical compliance must be maintained across systems and stakeholders.

Why is ISO/IEC 19794-4:2005/COR1:2011 important?

For organizations working with fingerprint image data, even a corrigendum can affect technical accuracy, interoperability, and quality assurance. ISO/IEC 19794-4:2005/COR1:2011 supports risk management by helping teams avoid implementing outdated or ambiguous wording from the parent document. It is useful in testing workflows, engineering validation, and regulatory preparation because it helps keep specifications aligned across design, verification activities, and documented evaluation. In procurement and compliance work, this can reduce rework and strengthen confidence that the referenced biometric format is being applied correctly.

• Supports corrected interpretation of the finger image data interchange format in the parent series
• Useful for technical review, verification activities, and laboratory evaluation of biometric implementations
• Helps maintain consistency in engineering documentation and compliance workflows
• Relevant for interoperability checks, procurement review, and conformity assessment preparation
