Consolidates information relating to successful, secure and usable implementation of biometric enrolment processes, while indicating risk factors that organisations proposing to use biometric technologies will should address during procurement, design, deployment and operation. Much of the information is generic to many types of application, e.g. from national scale commercial and government applications, to closed systems for in-house operations, and to consumer applications. However, the intended application and its purpose often have influence on the necessary enrolment data quality and are intended to be taken into account when specifying an enrolment system and process.
