17、ndardization. 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

18、of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. The procedures used to develop this docu

19、ment 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, P

20、art 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 develo

ISO/IEC 2015 All rights reserved v ISO/IEC TR 29196:2015(E) Introduction One of the most important contributions to a successful biometric-based recognition system is a consistent enrolment service that generates the biometric data required for subseq

24、uent recognition of individuals. Subsequent verifications or identifications will be compared with the biometric data collected at enrolment. If the quality of capture at enrolment is not maintained consistently, the operators of a recognition system which depends on a good enrolment are likely to e

25、xperience unreliable performance. For those who are enrolled in a verification system, a poor quality enrolment will result in inconvenience should they fail to be recognized. (Readers of this report should note that quality has a specific meaning when applied to biometric systems; a high quality ca

26、pture is one that results in biometric data that provides good match scores when compared with other high quality images from the same biometric feature.) By analysing the requirements for a good enrolment from the perspectives of a range of stakeholders, it is possible to derive a set of principles

27、 to guide the development of a biometric enrolment policy and the deployment of a service. Where enrolment is outsourced to a third party, it is extremely important to be able to measure quality metrics rather than quantity metrics, since the technical and business objectives of the two organisation

28、s (the Relying Party and the Enrolment Authority as defined in this document) may, in general, not be aligned. Although the recommendations and guidelines in this report are directed in the main at the parties responsible for the enrolment itself and for management of the enrolment service (noting t

29、hat these two entities may be one and the same), they will also be of value to the designers and developers of enrolment systems.vi ISO/IEC 2015 All rights reserved Guidance for biometric enrolment 1 Scope This report consolidates information relating to successful, secure and usable implementation

30、of biometric enrolment processes, while indicating areas of uncertainty that organisations proposing to use biometric technologies will need to address during procurement, design, deployment and operation. Much of the information is generic to many types of application e.g. from national scale comme

31、rcial and government applications, through to closed user group systems for in-house operations, and to consumer applications where convenience rather than security is the primary driver for adoption of biometric technologies. The report points out the differences in operation relating to specific t

32、ypes of application, e.g. where self-enrolment is more appropriate than attended operation. This report will focus in the main on fixed location enrolments at a number of sites in an organization, where there is an attendant who supports the biometric applicant in effecting a successful enrolment, a

33、nd where enrolment is a mandatory requirement. In summary, this report consolidates information relating to better practice implementation of biometric enrolment capability in various business contexts including considerations of legislation, policy, process, function (system) and technology. The re

34、port provides guidance as to the collection and storage of biometric enrolment data and the impact on dependent processes of verification and identification. This report will not aim to include material specific to forensic and law enforcement applications. The recommendations contained in the repor

35、t are not mandatory. 2 T erms a nd definiti ons For the purposes of this document, the terms and definitions given in ISO/IEC 2382-37 and the following apply. 2.1 biometric applicant individual seeking to be enrolled in a biometric enrolment database 2.2 designers and developers organization or indi

46、tric System Given the variety of applications and technologies, it might seem difficult to draw any generalizations about biometric systems. All such systems, however, have many elements in common. Captured biometric samples are acquired from a subject by a sensor. The sensor output is sent to a pro

47、cessor that extracts the distinctive but repeatable measures of the sample (the biometric features), discarding all other components. The resulting features can be stored in the biometric enrolment database as a biometric reference or (in this case) a biometric template. In other cases the sample it

48、self (without feature extraction) may be stored as the reference. A subsequent probe biometric sample can be compared to a specific reference, to many references or to all references already in the database to determine if there is a match. A decision regarding the biometric claim is made based upon

49、 the similarities or dissimilarities between the features of the biometric probe and those of the reference or references compared.
