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.

and biometric objects, and provides a description of BRA responsibilities and services. Procedural

requirements and recommendations are not within the scope of this document and are maintained

separately on the ISO/IEC JTC 1/SC 37 website .
