Identity management systems store attributes associated with users and employ these attributes to facilitate authorization. The authors analyze existing systems and describe a privacy-driven taxonomy of design choices, which can help technical experts consulting on public policy relating to identity management. The US National Strategy for Trusted Identities in Cyberspace initiative is discussed to illustrate how this taxonomy helps analyze public policy options.
