PD CEN/TS 16920:2016CEN/TS 16920:2016 (E) 4 Introduction This Technical Specification is focused on the application of the testing methodology defined in ISO/IEC 291
19、97 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
20、 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 object
21、ive 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
22、 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 n
23、ot 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 environment
24、al 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 en
25、vironments. 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 on
26、e 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 mod
27、alities 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 Europ
28、ean 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
29、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 c
30、omply 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 behaviou
31、r 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. PD CEN/TS 16920:2016CEN/TS 16920:2016 (E) 5 1 Scop
32、e 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
33、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 regulatio
34、ns 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 r

40、: The term “environmental conditions” entails more aspects than “ambient conditions”. However, the term “ambient conditions” can also refer to conditions that occur naturally in contrast to conditions that have been induced. Therefore, it has been preferred to use the term “environmental conditions”
41、. Note 2 to entry: It is important to distinguish two concepts related to this term: operational environment: the environmental conditions under which the European ABC system is expected to operate. This concept does not associate any predefined value; extreme conditions: environmental conditions th
42、at entail very high or very low values and may be hostile for systems operation or even human life. 3.2 environmental generator equipment used to establish and maintain the controlled conditions of the test (e.g. an air conditioning system) 3.3 evaluation conditions each of the evaluations carried o
43、ut in a different evaluation environment to assess the performance of European ABC systems in one or more specific environmental conditions 3.4 evaluation configuration physical layout of the environment in which the European ABC is going to be tested including the necessary equipments for performin
44、g tests 3.5 evaluation environment environment in which the biometric system is evaluated considering the environmental conditions and the evaluation configuration 3.6 instrument calibrated equipment used to measure and/or record environmental parameters (e.g. a thermometer) 3.7 parties involved in
45、the evaluation entities or organizations which are interested in the evaluation and have responsibilities in the evaluation process Note 1 to entry: These entities are basically two: the test laboratory which is going to conduct the evaluation and the developer or customer who request to carry out t
46、he evaluation. In case the developer is different from the customer (e.g. an end-user requesting to know the performance of a commercial European ABC system), a third entity is added to the number of parties. Note 2 to entry: Test subjects are not considered a party of the evaluation although they h
47、ave to take part in it.
