Abstract.

   Reputation and trust-based models have gained popularity
recently because they have been shown to be promising in the area of
trust management. Despite this fact, building reliable systems still remains
a challenge. Proposed models focus on historical and online information
to determine the reputation of domain members. However, the
dynamic nature of reputation and trust requires an equally dynamic approach
to computing and resolving trust related issues in any domain.
This paper proposes a reliable and novel dynamic framework that utilises
a data-driven approach for trust management. The framework uses past
interactions, recent and anticipated future trust values of every identity
in the domain. The proposed framework is critically evaluated and compared
with existing work through experiments. The advantage of this
proactive framework compared to other approaches is that informed decisions
about the domain can be made before misbehaviour occurs.

Keywords: trust dynamics, trust management, reputation.
