Introduction
ISO/IEC 19794-5:2005 specifies a data record interchange format for storing, recording, and
transmitting one or more face images within a Common Biometric Exchange Formats Framework
(CBEFF) data structure. Each image is accompanied by subject-specific and image-specific metadata
contained in a header record. This part of the ISO/IEC 29109 series establishes tests for checking the
correctness of the binary record.
The objective of ISO/IEC 19794-5:2005 cannot be completely achieved until biometric products can
be tested to determine whether they conform to those specifications. Conforming implementations
are a necessary prerequisite for achieving interoperability among implementations; therefore there
is a need for a standardized conformance testing methodology, test assertions, and test procedures
as applicable to specific modalities addressed by each part of ISO/IEC 19794. The test assertions will
cover as much as practical of the ISO/IEC 19794 requirements (covering the most critical features),
so that the conformity results produced by the test suites will reflect the real degree of conformity of
the implementations to ISO/IEC 19794 Data Interchange Format records. This is the motivation for the
development of this conformance testing methodology.
This document supports those applications that require use of face image data according to ISO/IEC
19794-5:2005. It defines a testing methodology to ensure conformance of a vendor’s application or
service to the base ISO/IEC 19794-5:2005 specification. Thus this document is intended to:
— establish elements of the Conformance Testing Methodology framework that are specific to the Face
Image-based Data Record requirements of ISO/IEC 19794-5:2005 conformance testing;
— define requirements and guidelines for specifying conformance test suites and related test
methods for measuring conformity of products and services to the Face Image-based Data Record
requirements of ISO/IEC 19794-5:2005; and
— define test procedures to be followed before, during, and after conformance testing.
This document is applicable to the development and use of conformity test method specifications,
conformity test suites for ISO/IEC 19794-5:2005 records, and conformance testing programs for ISO/
IEC 19794-5:2005 conformant products. It is intended primarily for use by testing organizations, but
may be applied by developers and users of test method specifications and test method implementations.
