Introduction
This Technical Specification is focused on the application of the testing methodology defined in
ISO/IEC 29197 for analysing the influence of environmental conditions on the biometric performance of
European automatic border control (ABC) systems according to the features of these systems, the
specificities of these systems for the European context and their intended operational environment, i.e.
airports and port halls.
ABC systems are automated systems which can verify the identity of travellers crossing the borders at
the border crossing points, without the need for human intervention. These systems are used by many
European countries for supporting border control officer activities. Their objective is to improve border
crossing processes and achieve consistent security levels throughout Europe. As a consequence, it is
required that these systems conform to ISO/IEC standards for interoperability (see
CEN/TS 16634:2014, Personal identification — Recommendations for using biometrics in European
Automated Border Control, Clause 1). Among these standards, the multipart standard ISO/IEC 19795
“Biometric Performance Testing and Reporting” establishes requirements for planning, executing and
reporting biometric performance evaluations. However, due to the fact that this set of standards does
not cover the analysis of environmental conditions influence on biometric performance, ISO/IEC JTC1
SC37 WG5 began a new project for establishing a testing methodology to quantify those environmental
effects. This project is ISO/IEC 29197 “Information technology — Evaluation methodology for
environmental influence in biometric system performance”.
However, this methodology is generic and its requirements have been specified to cover the analysis of
several environmental parameters (e.g. temperature, humidity, atmospheric pressure, illumination,
noise, etc.) considering all possible operational environments. Depending on the particular features of
the biometric system under test and the expected operational environment, those requirements should
be particularized.
European ABC systems have biometric modules which have common and well-defined features.
Firstly, European ABC systems may use one or a combination of three biometric modalities: facial,
fingerprint and iris (as it is specified by CEN/TS 16634:2014, Personal identification —
Recommendations for using biometrics in European Automated Border Control, 4.1). Therefore, there
are certain environmental conditions that affect such modalities to a greater extent according to
ISO/IEC/TR 19795-3.
On the other hand, European ABC systems are localized in specific environments such as airports,
railway stations and sea ports (as it is mentioned in CEN/TS 16634:2014, Personal identification —
Recommendations for using biometrics in European Automated Border Control, 5.1.1). As a result, it is
possible to predict which are going to be the surrounding environmental conditions of the ABC systems
and to analyse whether the systems work properly or not for the possible values of such conditions. If
the biometric performance of European ABC systems is affected by any environmental condition and
this problem is not detected in early stages, it may cause negatively effects in future.
In addition, European ABC systems are subjected to privacy and data protection legislation (e.g.
Directive 95/46/EC). Therefore, their analysis should comply with the limitations imposed by EU and
data protection regulations (see CEN/TS 16634:2014, Personal identification— Recommendations for
using biometrics in European Automated Border Control, 5.1.3.6 and 5.1.4).
Consequently and considering the importance to accurately check the correct behaviour of the
biometric recognition functionality of European ABC systems in their expected host environment, it is
essential to specify the general testing methodology addressed by ISO/IEC 29197 for the characteristics
and needs of European ABC systems.
1 Scope
The purpose of this document is to specify the ISO/IEC 29197 testing methodology for European ABC
systems. This specification will cover the following aspects:
— environmental conditions which influence biometric modalities used for European ABC systems, i.e.
temperature, humidity, illumination and noise;
— different tests that can be defined regarding European ABC systems and the procedures for defining
of the evaluation conditions to analyse per each test;
— particular characteristics of European ABC systems in accordance to best practice
recommendations and privacy and data protection regulations for this kind of systems in case of
European deployments.
As a consequence, the proposed document will include the following aspects:
— specific requirements for planning and executing environmental testing evaluations for European
ABC systems based on ISO/IEC 29197 project and the best practices recommendations provided by
CEN/TS 16634 Personal identification — Recommendations for using biometrics in European
Automated Border Control document;
— recommendations for the selection of the possible tests according to the specific system that is
going to be evaluated;
— specific requirements to establish and measure such evaluation conditions as well as to establish
the baseline performance;
— a specification of the biometric performance evaluation including requirements for test population,
test protocols, data to record and test results consistent with operational deployments of European
ABC systems.
