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 consists of the following parts, under the general title Information technology — Conformance

Introduction
ISO/IEC 19794-10:2007 specifies a data record interchange format for recording, storing, and transmitting one
or more hand geometry silhouette records. This part of ISO/IEC 29109 establishes tests for checking the
correctness of the binary record.
The objective of ISO/IEC 19794-10:2007 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 part of ISO/IEC 29109 supports those applications that require use of hand geometry silhouette data
according to ISO/IEC 19794-10:2007. It defines a testing methodology to ensure conformance of a vendor's
application or service to ISO/IEC 19794-10:2007. Thus this part of ISO/IEC 29109 is intended to:
⎯ establish elements of the Conformance Testing Methodology framework that are specific to the Hand
Geometry Silhouette-based Data Record requirements of ISO/IEC 19794-10:2007 conformance testing,
⎯ define requirements and guidelines for specifying conformance test suites and related test methods for
measuring conformity of products and services to the Hand Geometry Silhouette Data Record
requirements of ISO/IEC 19794-10:2007, 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 19794-10:2007 records, and conformance testing programs for
ISO/IEC 19794-10:2007 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. The
table of assertions in Clause 6 specifies levels of testing for the conformance requirements of
ISO/IEC 19794-10:2007.

INTERNATIONAL STANDARD ISO/IEC 29109-10:2010(E)

Information technology — Conformance testing methodology
for biometric data interchange formats defined
in ISO/IEC 19794 —
Part 10:
Hand geometry silhouette 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 19794-10.
This part of ISO/IEC 29109 establishes
⎯ test assertions of the structure of the hand geometry silhouette data format as specified in
ISO/IEC 19794-10:2007 (Type A Level 1 as defined in ISO/IEC 29109-1:2009),
⎯ test assertions of internal consistency by checking the types of values that may be contained within each
field (Type A Level 2 as defined in ISO/IEC 29109-1:2009),
⎯ informative guidance for testing the consistency of selected encoded data fields with the input biometric
data (Type B Level 3 as defined in ISO/IEC 29109-1:2009).
This part of ISO/IEC 29109 does not establish
⎯ test of conformance of CBEFF structures required by ISO/IEC 19794-10:2007,
⎯ test of consistency with input biometric data record (Level 3 as defined in ISO/IEC 29109-1:2009),
⎯ test of other characteristics of biometric products or other types of testing of biometric products (e.g.
acceptance, performance, robustness, security),
⎯ test of conformance of systems that do not produce ISO/IEC 19794-10:2007 records.
2 Conformance
Biometric data interchange format Conformance Test Suites (CTS) conform to this part of ISO/IEC 29109 if
they satisfy all of the normative requirements related to Clause 6. Additionally, implementations of Level 1 or
Level 2 tests shall use the assertions defined in Table 2 and fill out an Implementation Conformance
Statement (ICS) based on Table 1.
Implementations of ISO/IEC 19794-10:2007 tested according to the methodology specified shall be able to
claim conformance only to those Biometric Data Record (BDR) requirements specified in
ISO/IEC 19794-10:2007 that are tested by the test methods established by this methodology.

---------------------- Page: 6 ----------------------
ISO/IEC 29109-10:2010(E)
Implementations of ISO/IEC 19794-10:2007 do not necessarily need to conform to all possible aspects of
ISO/IEC 19794-10:2007, but only to those ISO/IEC 19794-10:2007 requirements that are claimed to be
supported by the implementation in an Implementation Conformance Statement, filled out in accordance with
Clause 8 of ISO/IEC 29109-1:2009 and Table 1 of this part of ISO/IEC 29109.
A system does not need to be capable of using biometric data records that cover all possible aspects of
ISO/IEC 19794-10:2007, but only those that are claimed to be supported by the system in an Implementation
Conformance Statement, filled out using the template provided in A.2.
NOTE Level 3 and higher are not tested.
