Unformatted text preview: Anonymity, Unlinkability, Unobservability, Pseudonymity, and Identity Management A Consolidated Proposal for Terminology (Version v0.26 Dec. 13, 2005) Andreas Pfitzmann Marit Hansen TU Dresden ULD Kiel pfitza@inf.tu-dresden.de marit.hansen@datenschutzzentrum.de Archive of this Document http://dud.inf.tu-dresden.de/Anon_Terminology.shtml (v0.5 and all succeeding versions) Abstract Based on the nomenclature of the early papers in the field, we propose a terminology which is both expressive and precise. More particularly, we define anonymity , unlinkability , unobservability , pseudonymity ( pseudonyms and digital pseudonyms , and their attributes), and identity management . In addition, we describe the relationships between these terms, give a rational why we define them as we do, and sketch the main mechanisms to provide for the properties defined.
