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

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.

are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria
needed for the different types of ISO document should be noted. This document was drafted in

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 previous enrolment and management 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 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, cost effective,
maintain the security requirements, and provide permission-based access and global interoperability as
necessary. Biometric systems should effectively allow authorized users’ access, 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
work place 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 for design of
contactless biometric recognition systems. Design considerations include:
— Selection and placement of biometric data capturing devices (e.g. cameras).
— Control of the flow of individuals requiring access to ensure that only those that are authorized gain
access.
— Proximity of capture devices to individuals seeking access for the contactless in-motion capture of
the needed information. The proximity of the biometric capture devices can depend on the employed
biometric modalities.
— Management of exceptions.
— Mutual placement of capture devices and equipment dedicated to physical access-control (e.g. door,
barrier, turnstile).
A number of use cases involving in-motion biometrics address different scenarios including:
