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 or www.iec.ch/members_experts/refdocs).

ISO and IEC draw attention to the possibility that the implementation of this document may involve the use of (a) patent(s). ISO and IEC take no position concerning the evidence, validity or applicability of any claimed patent rights in respect thereof. As of the date of publication of this document, ISO and IEC had not received notice of (a) patent(s) which may be required to implement this document. However, implementers are cautioned that this may not represent the latest information, which may be obtained from the patent database available at www.iso.org/patents and https://patents.iec.ch. ISO and IEC shall not be held responsible for identifying any or all such patent rights.

This document was prepared by Joint Technical Committee ISO/IEC JTC 1 , Information technology, Subcommittee SC 17, Cards and security devices for personal identification.

This second edition cancels and replaces the first edition ( ISO/IEC 17839:2014 ), which has been technically revised.

The main changes are as follows:

updated Biometric System-on-Card architecture in alignment with ISO/IEC 24787-1 ;
replaced references to S1 and S2 with ID-1 and ID-T;
removed normative references to ISO/IEC 15693 ;
added diagram for feedback.

A list of all parts in the ISO/IEC 17839 series can be found on the ISO and IEC websites.

Any feedback or questions on this document should be directed to the user’s national standards body. A complete listing of these bodies can be found at www.iso.org/members.html and www.iec.ch/national-committees.

Introduction

In the context of this document, a Biometric System-on-Card is a portable card-sized device including the following entities: biometric capture, data processing, storage, comparison, decision, and action. It is a functional extension to on-card biometric comparison by physically and logically integrating the sensor and signal processing into the card.

ISO/IEC 7816-11 , ISO/IEC 19785-3 , ISO/IEC 19795-7 and ISO/IEC 24787-1 include technologies with respect to on-card biometric comparison.

The physical integration of a biometric sensor in an ISO/IEC 7810 card withstanding torsion and bending tests is technically challenging. This document describes two types of Biometric System-on-Card. Type ID-1 BSoC is a flexible card fully conformant to ISO/IEC 7810 while Type ID-T BSoC conformant to Annex A of ISO/IEC 18328-2:2021 intentionally deviates from some of the requirements to size and bending stiffness, keeping the rest of the requirements intact, including the use of a contactless ICC interface.

The ISO/IEC 17839 series is currently organized in 3 separate documents:

ISO/IEC 17839-1 , Biometric System-on-Card — Part 1: Core requirements (this document)
ISO/IEC 17839-2 , Biometric System-on-Card — Part 2: Physical characteristics
ISO/IEC 17839-3 , Biometric System-on-Card — Part 3: Logical information interchange mechanism

1 Scope

This document establishes:

functional architecture of a Biometric System-on-Card (BSoC);
definition of Type ID-1 BSoC ( ISO/IEC 7810 conformant) and Type ID-T BSoC (see ISO/IEC 18328-2:2021, Annex A) implementation of a BSoC;
sensor types in a BSoC;
requirements to a BSoC with respect to:
- discriminative power (i.e. biometric accuracy criteria);
- interfaces;
- power supply options.
The following aspects are out of scope of this document (see ISO/IEC 24787-1 ):
off-card biometric comparison, storage-on-card;
on-card biometric comparison (sensor-off-card);
work-sharing implementations;
detailed specification and configuration of individual components.

This document provides a functional architectural description of a BSoC and describes how the interfaces are mapped using existing commands and data structures from other International Standards.
