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.

Introduction
On-card biometric comparison provides a more secure biometric verification method than off-card biometric
comparison, as the comparison is executed inside the integrated circuit card (ICC) and the biometric reference
is never revealed outside the ICC. ISO/IEC 24787-2 specifies a set of requirements for implementing work-
sharing mechanism of biometric comparison inside the ICC. An ICC application that claims conformance to
ISO/IEC 24787-2 fulfils a set of requirements outlined in this document. The requirements are established
for on-card biometric comparison, which is in a sensor-off card device, as defined in ISO/IEC 24787-2.

1 Scope
This document establishes conformance testing for the requirement described in ISO/IEC 24787-2, which is:
— work-sharing on-card biometric comparison.
Measuring the performance of on-card biometric comparison algorithms such as error rates or speed is not
within the scope of this document.
