This document discusses identity management in e-government. It defines identity management as dealing with identifying individuals in a system and controlling their access to resources. Key components include authentication, access control, accounting, and user management. The EU's eIDAS Regulation aims to facilitate cross-border authentication by establishing assurance levels for eID schemes and requiring mutual recognition. Challenges include a lack of interoperability between countries' systems and ensuring privacy and data protection as personal data is shared for authentication. The regulation and proposals aim to establish common standards and processes to address these issues.
