AS ISO IEC 19795.2 pdf download – Information technology—Biometric performance testing and reporting Part 2: Testing methodologies for technology and scenario evaluation
This part of lSOIEC 19795 provides requirements and recommendations on data collection, analysis andreporting specific to two primary types of evaluation: technology evaluation and scenario evaluation.
This part of lSO/IEC 19795 specifies requirements in the following areas:
— development and full description of protocols for technology and scenario evaluations;
execution and reporting of biometric evaluations reflective of the parameters associated with biometricevaluation types.
2 Conformance
A test shall claim conformance to either the technology evaluation or scenario evaluation clauses of this partof ISO/IEC 19795.
The set of clauses to which a scenario test shall conform differs from the set of clauses to which a technologytest shall conform. In addition, the set of clauses to which an identification-system test shall conform differsfrom the set of clauses to which a verification-system test shall conform. To conform to this part ofISO/IEC 19795, an evaluation shall conform to clauses of this part of lSOIEC 19795 as shown in Table 1.

4Terms and definitions
For the purposes of this document, the terms and definitions given in ISOIEC 19795-1:2006 and the followingapply.
4.1 Biometric data
4.1.1
biometric reference
(template, model) user’s stored reference measure based on features extracted from enrolment samples
4.2components of a biometric system
4.2.1
feature extractor
apparatus that extracts features from a sample
4.2.2
biometric reference generator
apparatus that transforms a sample into a biometric reference
4.3User interaction with a biometric system
4.3.1
acclimatization
reduction,over the course of an evaluation, in a temporal condition of a biometric characteristic that mayimpact the ability of a sensor to process a sample
4.3.2
effort level
number of presentations, attempts or transactions needed to successfully enrol or match in a biometric system
4.3.3
enrolment attempt
submission of one or more biometric samples for a Test Subject for the purpose of enrolment in a biometricsystem
NOTE1 One or more enrolment attempts may be pemitled or required to constiute an enroiment transaction.Anenrollment attempt may comprise one or more enrolment presentations.
NOTE2 See Annex B for illustration of the relationship between presentation, attempt and transaction.
4.3.4
enrolment attempt limit
maximum number of attempts, or the maximum duration, a Test Subject is permitted before an enrolmenttransaction is terminated
4.3.5
enrolment presentation
submission of an instance of a biometric characteristic for a Test Subject for the purpose of enrolment
NOTE One or more enrolment presentations may be permitted or required to constitute an enrolment attempt. Anenrollment presentation may or may not result in an enrolment attempt.
4.3.6
enrolment presentation limit
maximum number of presentations, or the maximum duration, a Test Subject is permitted before an enrolmentattempt is terminated
