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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for
the different types of document should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of any patent rights identified during the development of the document will be in the
Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

as well as information about ISO’s adherence to the World Trade Organization (WTO) principles in the
Technical Barriers to Trade (TBT) see the following URL: www.iso.org/iso/foreword.html.
Amendment 2 to ISO/IEC 19794-6:2011 was prepared by Joint Technical Committee ISO/IEC JTC 1,

Part 6:
Iris image data
AMENDMENT 2: XML encoding and clarification of defects
Page v, Introduction
Add the following paragraph to the end of the Introduction
Additionally, this document supports both binary and XML encodings, to support a spectrum of user
requirement. With XML, this document will meet the requirements modern IT architectures. With
binary encoding, this document will also be able to be used in bandwidth or storage constrained
environments. Annex G specifies the schema that XML-encoded iris image records must conform to.
Annex H provides an example of a valid XML-encoded iris image record.

Page 1, Clause 2   Conformance
Replace the existing text in Clause 2   Conformance with the following:
A binary data record conforms to this document if it satisfies all the format requirements with respect
to its structure, data values, relationships among its fields, and with respect to relations between its
fields and the underlying input that are specified throughout Clause 7.
An XML document conforms to this document if it satisfies the format requirements with respect to its
structure, with respect to relations among its fields, and with respect to relations between its fields
and the underlying input that are specified within Annex C.
A system that produces biometric data records is conformant to this document if all biometric data
records that it outputs conform to this document (as defined above) as claimed in the Implementation
Conformance Statement associated with that system. A system does not need to be capable of producing
biometric data records that cover all possible aspects of this document, but only those that are claimed
to be supported by the system in the Implementation Conformance Statement (ICS).
A system that uses biometric data records is conformant to this document if it can read, and use for
the purpose intended by that system, all biometric data records that conform to this document (as
defined above) as claimed in the Implementation Conformance Statement associated with that system.
A system does not need to be capable of using biometric data records that cover all possible aspects
of this document, but only those that are claimed to be supported by the system in an Implementation
Conformance Statement (ICS).
Biometric data interchange format conformance tests conform to this document if they satisfy all of the
normative requirements set forth in Annex A. Specifically, all Level-1, Level-2 and Level-3 tests shall
use the assertions defined in Table A.2 and Table A.3 in conformity with the concept and rules set in
ISO/IEC 19794-1:2011/Amd 1:2013.
Implementations of this document tested according to the specified methodology shall be able to claim
conformance only to those biometric data record (BDB) requirements specified in this document that
are tested by the test methods established by this methodology.

Implementations of this document do not necessarily need to conform to all possible aspects of this
document, but only to those requirements that are claimed to be supported by the implementation
in an implementation conformance statement (ICS), filled out in accordance with ISO/IEC 19794-
1:2011/Amd 1:2013, Annex A and Table A.1.

Replace A.3 with the following:
A.3 Table of test assertions for binary encoded records
The specific test assertions required for conformance testing for binary records to this document are
listed in Table A.2, which extends over multiple pages. The conformance test assertions are listed in the
order in that the corresponding fields are required to appear, if present, in a conforming record. The
normative requirements of this document, as summarized in Table A.1, are referenced in the tables.

Page XX, Annex A
Rename Table A.2 to:
Table A.2 — Level 1 and Level 2 Conformance Test assertions for all binary encoded records
Rename Table A.3 to:
Table A.3 — Level 1 and Level 2 Conformance Test assertions for Type 1 binary encoded records
Rename Table A.4 to:
Table A.4 — Level 1 and Level 2 Conformance Test assertions for Type 2 binary encoded records
Rename Table A.5 to:
Table A.5 — Level 1 and Level 2 Conformance Test assertions for Type 3 binary encoded records
Rename Table A.6 to:
Table A.6 — Level 1 and Level 2 Conformance Test assertions for Type 7 binary encoded records
Add new section A.4:

The specific test assertions required for conformance testing for XML-encoded records to this document
are listed in Tables A.7, A.8, A.9, A.10 and A.11, which may extend over multiple pages. The conformance
test assertions are listed in the order in that the corresponding fields are required to appear, if present,
in a conforming record. The normative requirements of this document, as summarized in Table A.1, are
referenced in the tables.
