ISO/IEC 29109-5:2011 supports applications using face images formatted according to ISO/IEC 19794-5:2005. It defines conformance test assertions that allow a receiving system to check the encoding requirements of ISO/IEC 19794-5:2005 are met and are internally consistent. Formally, ISO/IEC 29109-5:2011 establishes requirements for a conformance test suite that assesses conformity of ISO/IEC 19794-5:2005 records from 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. It does not establish tests for checking the visual appearance requirements of an ISO/IEC 19794-5:2005 face.

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 29109-5 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 37, Biometrics.

ISO/IEC 29109-5:2011(E)
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 ISO/IEC 29109 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 part of ISO/IEC 29109 supports those applications that require use of face image data according to
ISO/IEC 19794-5:2005. It defines a testing methodology to assure conformance of a vendor's application or
service to the base ISO/IEC 19794-5:2005 specification. Thus this part of ISO/IEC 29109 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 part of ISO/IEC 29109 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 can be applied
by developers and users of test method specifications and test method implementations.

ISO/IEC 19794 —
Part 5:
Face image data
1 Scope
This part of ISO/IEC 29109 specifies elements of conformance testing methodology, test assertions, and test
procedures as applicable to the ISO/IEC 19794-5:2005 biometric data interchange format standard for face
image data.
This part of ISO/IEC 29109 establishes
⎯ test assertions of the structure of the face image data format as specified in ISO/IEC 19794-5:2005 (Type
A Level 1 as defined in ISO/IEC 29109-1:2009),
⎯ 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 29109-1:2009),
⎯ tests of semantic assertions (Type A Level 3 as defined in ISO/IEC 29109-1:2009).
This part of ISO/IEC 29109 does not establish
⎯ tests of conformance of CBEFF structures required by ISO/IEC 19794-5:2005,
⎯ tests of consistency with the input biometric data record (Level 3),
⎯ tests of conformance of the image data to the quality-related specifications of ISO/IEC 19794-5:2005,
⎯ tests of conformance of the image data blocks to the respective JPEG or JPEG 2000 standards,
⎯ tests of other characteristics of biometric products or other types of testing of biometric products (e.g.
acceptance, performance, robustness, security),
⎯ tests of conformance of 3D face records defined in ISO/IEC 19794-5:2005/Amd.2.
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 19794-5:2005 tested according to the methodology specified shall be able to
claim conformance only to those Biometric Data Record (BDR) requirements specified in
ISO/IEC 19794-5:2005 that are tested by the test methods established by this methodology.
Implementations of ISO/IEC 19794-5:2005 do not necessarily need to conform to all possible aspects of
ISO/IEC 19794-5:2005, but only to those ISO/IEC 19794-5:2005 requirements that are claimed to be

execution starting from the frontal view. This order shall be given by Roll
(about the front axis), then Pitch (about the horizontal axis) and finally
Yaw (about the vertical axis). The (first executed) Roll transformation will
therefore always be in the image (x,y) plane.
From the point of view of executing a transformation from the observed
view to a frontal view, the transformation order will therefore be Yaw,
Pitch, and then Roll. Note however that the encoded angle is from the
frontal view to the observed view.
R-16 5.5.8.1 Pose Angle – Yaw 1 M Y Y Y
The yaw angle Y is the rotation in degrees about the y-axis (vertical axis)
shown in [ISO/IEC 19794-5:2005] Figure 4. Frontal faces have a yaw
angle of 0 degrees. Positive angles represent faces looking to their left (a
counter-clockwise rotation around the y-axis).
The encoding B of the yaw angle Y shall be in degrees as a byte (1
Y

Frontal faces have a roll angle of 0 degrees. Positive angles represent
faces tilted toward their right shoulder (counter-clockwise rotation around
the z-axis).
The encoding B of the yaw angle R shall be in degrees as a byte (1
R
byte) with values from –180 to 180 modulo 2.

uncertainty specified by each vendor.
The encoding of Pose Angle Uncertainty is given by bytes (U , U , U )
Y P R
where each byte U in the field (k=Y,P,R) represents 1 degree of
K
uncertainty with minimum and maximum values of 1 and 181 where
U =(uncertainty+1). The more uncertain, the value of the uncertainty U

19794-5:2005] Figure 2. One Image Data block shall follow this block.
R-26 5.7.1 Face Image Type 1 M Y Y Y
The Face Image Type field shall represent the type of the facial image
stored in the Image Data Block according to [ISO/IEC 19794-5:2005]
Table 10. Note that all Frontal Image Types are either Full Frontal or
Token Frontal. Therefore a separate Frontal Value is not required.
The Basic Face Image Type is defined in [ISO/IEC 19794-5:2005] clause
6. The Frontal, Frontal/Full and Frontal/Token Face Image Types are
defined in [ISO/IEC 19794-5:2005] clauses 7, 8, and 9 respectively. Face
Image Types use the notion of inheritance. For example, the Frontal
Face Image Type inherits all of the requirements of the Basic Face
Image Type - the Frontal Face Image type obeys all normative
requirements of the Basic Face Image Type. The inheritance structure of
currently defined image types is shown in [ISO/IEC 19794-5:2005] Figure
