During the last few years, the topics of user/password pairs, single-sign-on and digital signature keys have matured into 'identity management'. Unfortunately, the standards groups and the purveyors of currently-available identity management products have built on a swamp.

This presentation will show how some fundamental misunderstandings are rendering current approaches ineffective. It will draw on material from a recent monograph on the topic, in order to distinguish the various competing architectures, and highlight the issues that need to be addressed.
