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.
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) or the IEC
list of patent declarations received (see http:// patents .iec .ch).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see
www .iso .org/ iso/ foreword .html.
This document was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 37, Biometrics.
This second edition cancels and replaces the first edition (ISO/IEC 19785-2:2006), which has been
technically revised. It also incorporates the Amendment ISO/IEC 19785-2:2006/Amd1: 2010 and the
Technical Corrigendum ISO/IEC 19785-2:2006/Cor: 2013.
The main changes compared to the previous edition are as follows:
— Biometric Registration Authority procedural requirements and recommendations were removed
from the standard and published on the ISO/IEC JTC 1/SC 37 website to comply with JTC 1
Supplement, JF.3.3.
— The registration identifier scheme was revised to correct issues with a valid representation of the
ASN.1 object identifier component.
— Support was added for additional biometric object types, including presentation attack detection
(PAD).
— Other minor technical and editorial changes were made to correct technical requirements and to
improve readability and organization.
A list of all parts in the ISO/IEC 19785 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Introduction
Biometric-based authentication systems and applications are expected to support multiple biometric
devices, multiple biometric data formats and multiple algorithms for feature extraction, comparison,
quality determination, presentation attack detection (PAD), and compression, possibly each from
a different vendor. The Common Biometric Exchange Formats Framework (CBEFF) promotes
interoperability of biometric-based application programmes and systems developed by different
vendors by facilitating biometric data interchange. This document supports such exchanges by
providing unambiguous identification of biometric organizations, formats and products, with separate
registration of identifiers for components of products that are biometric products, including specialized
products like capture devices, feature extraction algorithms, comparison algorithms, quality
algorithms, PAD mechanisms, or compression algorithms.
The Biometric Registration Authority (BRA) is the entity that facilitates globally unambiguous
identification of biometric objects and biometric organizations by maintaining and publishing a registry
of unique ASN.1 object identifiers. This document describes the universal identification scheme that
allows assignment of unique and unambiguous identifiers, and avoids changes in identifiers over time.
A general description of the BRA responsibilities and registration services is also included.
The publication of the registers promotes compatibility in interchange of biometric data and improves
interoperability of biometric systems. Registration provides an identifier, but registration should not
be regarded as a standardization procedure. Nevertheless, as a matter apart from registration, the
registered object may, but need not, be the subject of an international, national, or other standard.
