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
.
