Abstract

An understanding of the the Digital Persona concept, and its relationship to individuals and their identities, is central to the field of identity management and authentication. Yet, despite its importance, it is very poorly understood by information systems practitioners and even by researchers in the field. This seminar explains the concept within the context of a comprehensive theory of identity, and considers the concept's implications for the collection, storage, use and disclosure of personal data, and in particular the authentication of assertions of fact and of identity.
