e-ID is the central system for the identification and authentication of citizens in electronic administration. It is established as an integrated electronic identity system which provides adequate interfaces to all government e-services, to enable them to effectively identify and verify the identity of the citizen who is using them. e-ID enables management of a citizen’s electronic identity by creating a unified authentication system in an electronic environment, with no physical communication needed between the citizen and government bodies. The e-ID system, with electronic identity and a single sign-on mechanism, allows citizens to safely and conveniently use government e-services whilst, at the same time, revealing government bodies from having to manage an expensive user authentication infrastructure.
