Title : Emergence of Fairness in Trust Management Systems

Abstract:
 Trust Management is widely used to support users in making
decisions when the utility of their actions depends on behavior of others in
open, distributed systems. An intuitive expectation is that if all users of
the reputation system have similar characteristics, and the reputation
system is working well, then all users should have similar utilities. Such
an expectation can be formulated as a hypothesis: in successful reputation
(or trust management) systems, fairness should be an emergent property. The
notion of fairness can be precisely defined and investigated based on the
theory of equity. In this talk, we investigate the Fairness Emergence
hypothesis in reputation systems and prove that in realistic circumstances,
the hypothesis is valid. However, Fairness Emergence is not a universal
phenomenon. We study the sensitivity of Fairness Emergence to various
aspects of a reputation systems.
