What is ISO/IEC 39794‑6 about?
ISO/IEC 39794‑6 specifies generic extensible data interchange formats for the representation of iris image data, a tagged binary data format based on an extensible specification in ASN.1, and textual data format based on an XML schema definition that is both capable of holding the same information.
ISO/IEC 39794‑6 gives examples of data record contents, application-specific requirements, recommendations, and best practices in data acquisition and conformance test assertions and conformance test procedures applicable to this document.
ISO/IEC 39794‑6 specifies elements of conformance testing methodology, test assertions, and test procedures.
ISO/IEC 39794‑6 establishes test assertions pertaining to the structure of the iris image data format, test assertions pertaining to internal consistency by checking the types of values that may be contained within each field, and semantic test assertions.
Who is ISO/IEC 39794‑6 for?
ISO/IEC 39794‑6 on extensible biometric data interchange formats is useful for:
- Forensic laboratories
- Healthcare department
- High-security zones
- IT companies
- Government agencies
- Biometric device manufacturer companies
Why should you use ISO/IEC 39794‑6?
The exchange of iris information between equipment from different vendors can be achieved using images of the eye. While some applications can successfully operate with full-size uncompressed rectilinear images, there are others for which this is expensive in terms of storage and bandwidth.
The purpose of ISO/IEC 39794‑6 is to define an International Standard for the exchange of iris image extensible information.
ISO/IEC 39794‑6 contains a specific definition of iris image record attribute data elements, the record’s tagged binary, and XML encoding extensible formats for storing and transmitting the iris image and certain attribute data elements, and conformance criteria.
ISO/IEC 39794‑6 defines compact representations, Biometric data interchange formats enable the interoperability of different biometric systems. In anticipation of the future need for additional data elements and in order to avoid future compatibility issues.
