AS ISO IEC 19795.2 pdf download Information technology—Biometric performance testing and reporting Part 2: Testing methodologies for technology and scenario evaluation
1 Scope
This part of ISO/IEC 19795 provides requirements and recommendations on data collection, analysis and reporting specific to two primary types of evaluation: technology evaluation and scenario evaluation. This part of ISO/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 biometric evaluation types.
2 Conformance
A test shall claim conformance to either the technology evaluation or scenario evaluation clauses of this part of ISO/IEC 19795. The set of clauses to which a scenario test shall conform differs from the set of clauses to which a technology test shall conform.
In addition, the set of clauses to which an identification-system test shall conform differs from the set of clauses to which a verification-system test shall conform. To conform to this part of ISO/IEC 19795, an evaluation shall conform to clauses of this part of ISO/IEC 19795 as shown in Table 1.

4 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO/IEC 19795-1:2006 and the following apply.
4.1 Biometric data
4.1.1
biometric reference
〈template, model〉 user’s stored reference measure based on features extracted from enrolment samples
4.2 Components 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
4.3 User 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 may impact 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 biometric system
NOTE 1 One or more enrolment attempts may be permitted or required to constitute an enrolment transaction. An enrolment attempt may comprise one or more enrolment presentations.
NOTE 2 See Annex B for illustration of the relationship between presentation, attempt and transaction.
