ISO/IEC TR 29156:2015 PDF

ISO/IEC TR 29156:2015 provides guidance on specifying performance requirements for authentication using biometric recognition in order to achieve desired levels of security and usability for the authentication mechanism. Guidance addresses issues such as the following: - the biometric performance metrics that impact security and usability; - comparing and quantifying the security and usability of biometrics and other authentication mechanisms, when used alone or in combination; - how to combine performance of individual authentication elements in order to meet an overall security and usability requirement; - the trade-off between security and usability in applications using biometric recognition; - considerations in maintaining security and usability in systems incorporating biometrics. The guidance is targeted towards applications that - use biometrics for the authentication of individuals, and - are of small to medium size (in terms of the number of enrolled individuals). The guidance does not address the following: - surveillance systems; - systems whose primary aim is to detect and prevent attempts by individuals to create multiple enrolments under different identities; - systems with a large and diverse population of enrolees, which can include people with special needs; - other systems with a complex mix of functional, security and usability requirements. Such large-scale applications are typically the domain of large organizations, and it is assumed that the developers of such systems will have access to appropriate biometric expertise able to provide guidance beyond the scope of this Technical Report. This Technical Report does not address biometric modality and technology specific issues, nor does it provide quantitative biometric performance requirements that would satisfy a particular application.
