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
The presentation of an artefact or of human characteristics to a biometric capture subsystem in a fashion
intended to interfere with system policy is referred to as a presentation attack. The ISO/IEC 30107
series deals with techniques for the automated detection of presentation attacks. These techniques are
called Presentation Attack Detection (PAD) mechanisms.
[1]
PAD subsystems are commonly integrated into mobile devices . The following characteristics of
[2]
mobile devices necessitate the development of a profile of ISO/IEC 30107-3 specific to PAD testing :
— Mobile devices often have accelerated product development timelines, such that time and resources
for PAD testing may be limited.
— A single type of biometric subsystem is often integrated into a wide range of mobile devices, so
results from a single test may be applicable to multiple types of mobile devices.
— Biometric subsystems integrated into mobile devices are typically closed systems, such that
performance testing takes place through a full-system evaluation.
This document provides requirements for assessing the performance of PAD mechanisms on mobile
devices with local biometric recognition.

Part 4:
Profile for testing of mobile devices
1 Scope
This document is a profile that provides requirements for testing biometric presentation attack
detection (PAD) mechanisms on mobile devices with local biometric recognition.
This document lists requirements from ISO/IEC 30107-3 specific to mobile devices. It also establishes
new requirements not present in ISO/IEC 30107-3. For each requirement, the profile defines an
Approach in Presentation Attack Detection (PAD) Testing for Mobile Devices. For some requirements,
numerical values or ranges are provided in the form of best practices.
This profile is applicable to mobile devices that operate as closed systems with no access to internal
results, including mobile devices with local biometric recognition as well as biometric modules for
mobile devices.
Out of the scope of this document are the following:
— mobile devices solely with remote biometric recognition.
The attacks considered in this document take place at the sensor during the presentation and collection
of the biometric characteristics. Any other attacks are outside the scope of this document.
