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: Finger minutia data
Amendment 2: XML encoding and clarification of defects
1. Append the following paragraph into introduction
Additionally, this part of the ISO/IEC standard supports both binary and XML encoding, to
support a spectrum of user requirement. With XML, this part will meet the requirements modern
IT architectures. With binary encoding this part will also be able to be used in bandwitdth or
storage constrained environments. Annex G specifies the schema that XML encoded finger
minutia records must conform to, and Annex H provides an example of a valid XML encoded
finger minutia record.
2. Replace the existing text in clause “2– Conformance” with the following
A binary data record conforms to the finger minutiae record format of this part of ISO/IEC 19794
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 8 of this part of ISO/IEC 19794.
A binary data record conforms to the finger minutiae on-card comparison record format of this
part of ISO/IEC 19794 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 9 of this part of ISO/IEC 19794.
An XML document conforms to this part of ISO/IEC 19794 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 G of this
part of ISO/IEC 19794.
A system that produces biometric data records is conformant to this part of ISO/IEC 19794 if all
biometric data records that it outputs conform to this part of ISO/IEC 19794 (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 part of ISO/IEC 19794, 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 part of ISO/IEC 19794 if it can
read, and use for the purpose intended by that system, all biometric data records that conform
to this part of ISO/IEC 19794 (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 part of ISO/IEC 19794, but

---------------------- Page: 4 ----------------------
ISO/IEC 19794-2:2011/Amd 2:2015(E)
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 part of ISO/IEC 19794 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 of clause
A.3 in conformity with the concept and rules set in ISO/IEC 19794-1:2011 AMD 1.

Implementations of this part of ISO/IEC 19794 tested according to the specified methodology
shall be able to claim conformance only to those biometric data record (BDB) requirements
specified in this part of ISO/IEC 19794 that are tested by the test methods established by this
methodology.

Implementations of this part of ISO/IEC 19794 do not necessarily need to conform to all
possible aspects of this part of ISO/IEC 19794, 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 Annex A of ISO/IEC 19794-1:2011 AMD 1 and Table A.1 of clause A.2
of this part of ISO/IEC 19794.
3. Insert the following text in the appropriate alphabetical order of Clause 3,
Normative references:

sented by their X and Y coordinates. The
origin of the coordinate system shall be the
upper left corner of the original image with X
increasing to the right and Y increasing
downward.
R-80 6.4.3 The minutia for a ridge ending shall be de- 3C O-1 Y Y Y  N/A
fined as the point of forking of the medial
skeleton of the valley area immediately in
front of the ridge ending.
R-81 6.4.4 The minutia for a ridge bifurcation shall be 3C O-1 Y Y Y  N/A
defined as the point of forking of the medial
skeleton of the ridge.
R-82 6.4.5 The minutia for a ridge skeleton endpoint 3C O-1 Y Y Y  N/A
shall be defined as the center point of the
ending ridge.
R-83 6.7 All multibyte quantities are represented in 1 M Y Y N
Big-Endian format; that is, the more sig-
nificant bytes of any multibyte quantity are
stored at lower addresses in memory than
(and are transmitted before) less significant
bytes. All numeric values are fixed-length
integer quantities, and are unsigned
quantities.
R-84 9.1 A series of minutiae descriptions shall be 1 M N Y N
embedded in a tag-length-value encoded
biometric data object as defined in ISO/IEC
7816-11.
R-85 9.2.3 The 8-bit X coordinate of the minutia shall be 1 M N Y N
recorded in the first byte.
R-86 9.2.3 The 8-bit Y coordinate shall be placed in the 1 M N Y N
second byte.
R-87 9.2.3 The coordinates shall be expressed such 3C O-1 N Y N  N/A

that each unit is equal to 10 mm.
R-88 9.2.4 The type of a minutia shall be recorded in 1 M N Y N
the first two bits of the angle value for the
minutia.
R-89 9.2.5 The angle of the minutia shall be recorded in 1 M N Y N
six bits.
R-90 9.2.5 The angle of the minutia shall be recorded in 3C O-1 N Y N  N/A
units of 5.625 (360/64) degrees.

6. Replace the header of 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 Part of
ISO/IEC 19794 are listed in Table A.2. 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 part of ISO/IEC 19794 as summarized in Table A.1 are
referenced in Table.
7. Rename Table A.2 as Test assertions for binary encoded records
8. Add new section A.4
A.4 Table of test assertions for xml encoded records
The specific test assertions required for conformance testing for xml encoded records to this
Part of ISO/IEC 19794 are listed in Table A.3, 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. As many requirements for encoding are described
in the schema, the table only enumerates assertions that cannot be handled by using the
schema. The normative requirements of this part of ISO/IEC 19794 as summarized in Table
A.1 are referenced in Table.
