This International Standard addresses:

  • requirements for planning, executing and reporting the influence of user interaction on biometric system performance based on scenario test methodologies, considering three kinds of factors:

    • Factors related to the design, position or condition of the capture device

    • Factors depending on users and user attributes

    • Factors depending on the interaction of users with the biometric system

  • specifications for the definition, establishment and measurement of conditions needed for evaluation, including that relating to equipment,

  • requirements for establishing a reference evaluation condition and target evaluation condition(s) to compare the influence of user interaction factors,

  • a specification of the biometric evaluation including requirements for test population, test protocols, data to record, test results, and

  • procedures for carrying out the overall evaluation.

This standard does not

  • determine which parameters should be analysed for a specific biometric modality. This is currently covered in 19795:2007[1],

  • specify requirements to perform a vulnerability analysis modifying user interaction influence factors, or

  • include procedures for performing usability testing.

It is important to differentiate between “usability testing” and “user interaction influence in performance”. Usability testing relates to “the extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency, and satisfaction in a specified context of use” (ISO/IEC 9241-11:1998[3]). Usability testing involves the measurement of “how usable” a specific system or product is. Standards covering usability testing include to ISO/IEC TR 25060:2010.
