Information technology — Biometric recognition of subjects in motion in access-related systems
This document establishes requirements for the development of biometric solutions for verification and identification processes for secure access without physical contact with any device at any time. The solutions acquire biometric characteristics that are captured while the data subjects are in motion to verify or identify the individuals requiring access, thus controlling access using contactless biometrics.

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).

Introduction
The purpose of this document is to provide guidance on the use of in-motion biometric recognition
technologies in access-related systems, where the management and prior enrolment of the identity of
individuals needing access is required.
To satisfy increasing security demands, biometric recognition technologies are used in access-related
systems to provide a more robust approach to identity authentication and to mitigate security risks.
However, this can come at a cost of increased processing times and can lead to delays in user identification
or verification.
Biometric identification and verification should be comprehensive and flexible for effective use in an
access-related environment. Solutions should reduce user burden, be easy to manage and cost effective,
maintain security requirements, and provide permission-based access and global interoperability as
necessary. Biometric systems should effectively allow access to authorized users, incorporate mechanical
and behavioural mechanisms to refer unenrolled persons to human personnel, and alert facilities to
unauthorized users attempting to gain access. Systems should also provide a seamless, accurate and non-
invasive user experience.
Considerable improvements in the performance of in-motion biometric recognition have resulted in
applications that enable automated, convenient and non-intrusive face, iris or fingerprint recognition across
a range of scenarios, including border control, passenger flow facilitation, access control and monitoring
workplace time and attendance. This provides a positive and non-intrusive user experience, as the user does
not need to carry anything or stop and stand still to be recognized and does not need to touch anything.
There are several considerations that are unique to in-motion biometric solutions
