Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are members of
ISO or IEC participate in the development of International Standards through technical committees
established by the respective organization to deal with particular fields of technical activity. ISO and IEC
technical committees collaborate in fields of mutual interest. Other international organizations, governmental
and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information
technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International
Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as
an International Standard requires approval by at least 75 % of the national bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
ISO/IEC 29109-9 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 37, Biometrics.
ISO/IEC 29109 consists of the following parts, under the general title Information technology — Conformance
testing methodology for biometric data interchange formats defined in ISO/IEC 19794:
⎯ Part 1: Generalized conformance testing methodology
⎯ Part 2: Finger minutiae data
⎯ Part 4: Finger image data
⎯ Part 5: Face image data
⎯ Part 6: Iris image data
⎯ Part 7: Signature/sign time series data
⎯ Part 8: Finger pattern skeletal data
⎯ Part 9: Vascular image data
⎯ Part 10: Hand geometry silhouette data
The following parts are under preparation:
⎯ Part 14: DNA data
Finger pattern spectral data, signature/sign processed dynamic data and voice data will form the subjects of
future parts.

Introduction
ISO/IEC 19794-9:2007 specifies a data record interchange format for exchange of human vascular image
data among systems within a Common Biometric Exchange Formats Framework (CBEFF) data structure. The
data stored in a vascular data record often contains the metadata storing the subject-specific and image-
specific, as well as the technology being used. This part of ISO/IEC 29109 establishes tests for checking the
correctness of the binary record.
When vascular image data is transmitted among systems, it can be interfered with by noise due to the
transmission line. The received data might be incorrect during the exchange process. Therefore, there is a
need to conduct conformance tests of commercial products to determine whether the data conform to
ISO/IEC 19794-9:2007 before using the data for other purposes.
Vascular biometric technology is emerging or is under development by many research organizations. The
vascular image resources are also being used by many vendors, who have utilized the vascular technology as
a recognition or verification method in their systems. Currently, however, there is no standardized method for
conducting conformance tests of vascular image data that supports ISO/IEC 19794-9:2007 during the
exchange of vascular image data among systems. Application developers and implementers of different
organizations can interpret ISO/IEC 19794-9:2007 in different manners. Therefore, a standardized
conformance testing methodology is necessary for achieving interoperability among implementations.
This part of ISO/IEC 29109 supports those applications that require use of vascular image data according to
ISO/IEC 19794-9:2007. It defines a testing methodology to ensure conformance of a vendor’s application or
service to ISO/IEC 19794-9:2007. Thus, it is intended to:
⎯ establish elements of the conformance testing methodology framework that are specific to the vascular
image-based data record requirements of ISO/IEC 19794-9:2007 conformance testing;
⎯ define requirements and guidelines for specifying conformance test suites and related test methods for
measuring conformity of products and services to the vascular image data record requirements of
ISO/IEC 19794-9:2007; and
⎯ define testing and reporting procedures to be followed before, during, and after conformance testing.
This part of ISO/IEC 29109 is applicable to the development and use of conformity test method specifications,
conformity test suites for ISO/IEC 19794-9:2007 records, and conformance testing programs for
ISO/IEC 19794-9:2007 conformant products. It is intended primarily for use by testing organizations, but can
be applied by developers and users of test method specifications and test method implementations.

INTERNATIONAL STANDARD ISO/IEC 29109-9:2011(E)

Information technology — Conformance testing methodology
for biometric data interchange formats defined in
ISO/IEC 19794 —
Part 9:
Vascular image data
1 Scope
This part of ISO/IEC 29109 specifies elements of conformance testing methodology, test assertions, and test
procedures as applicable to ISO/IEC 19794-9.
It specifies
⎯ test assertions of the structure of the vascular image data format as specified in ISO/IEC 19794-9:2007
(Type A Level 1 as defined in ISO/IEC 29109-1),
⎯ test assertions of internal consistency by checking the types of values that can be contained within each
field (Type A Level 2 as defined in ISO/IEC 29109-1).
It does not specify
⎯ a test of conformance of CBEFF structures required by ISO/IEC 19794-9:2007,
⎯ a test of consistency with an input biometric data record (Level 3),
⎯ a test of other characteristics of biometric products or other types of testing of biometric products
(e.g. acceptance, performance, robustness, security),
⎯ a test of conformance of systems that do not produce ISO/IEC 19794-9:2007 records.
2 Conformance
Biometric data interchange format conformance tests conform to this part of ISO/IEC 29109 if they satisfy all
of the normative requirements related to Clause 6. Specifically, they shall use the test methodology specified
in Clauses 6, 7 and 8 of ISO/IEC 29109-1:2009, and all Level 1 and Level 2 tests shall use the assertions
defined in Table 2 in this part of ISO/IEC 29109.
Implementations of ISO/IEC 19794-9:2007 tested according to the specified methodology shall be able to claim
conformance only to those Biometric Data Record (BDR) requirements specified in ISO/IEC 19794-9:2007 that
are tested by the test methods established by this methodology.
Implementations of ISO/IEC 19794-9:2007 do not necessarily need to conform to all possible aspects of
ISO/IEC 19794-9:2007, but only to those ISO/IEC 19794-9:2007 requirements that are claimed to be
supported by the implementation in an Implementation Conformance Statement (ICS), filled out in accordance
with Clause 8 of ISO/IEC 29109-1:2009 and Table 1 in this part of ISO/IEC 29109.
NOTE Level 3 and higher are not tested.
