Traditionally, Grid users have been identifiable and traceable beyond reasonable doubt by their
digital certificates. However, Grids are used in an ever-increasing variety of contexts and thus, the
number of usage scenarios has augmented accordingly. In bio-medicine and other health-related
fields a need for anonymous access to Grid resources has been identified. Anonymous access to
resources prevents the resource owners and other external parties from tracing the users and their
actions. Such anonymity of resource usage in Grids is needed above all in commercial contexts,
e.g. protecting the development process of a new medicine by anonymizing the accesses to
medical research databases. In this paper we identify the requirements and define an architecture
for pseudonymity system addressing these needs. Also the protocols used between the
components are defined.
