Information technology — Guidance for biometric enrolment
This document 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…

This document provides recommendations and checklists which can be used to support the specification and operational testing of cryptographic modules in their operational environment within an organization's security system. The cryptographic modules have four security levels which ISO/IEC 19790 defines to provide for a wide spectrum of data sensitivity (e.g. low-value administrative data,…
