Intelligent Agents, Fuzzy Logic and Security in E-commerce.
Current e-commerce applications provide us a binary
definition of trust depending on whether some
requirements are satisfied or not. However trust can be
seen as a more general and subjective concept tightly
linked to reputation. The potential great number of
participants in open systems like Internet makes this kind
of trust harder to manage. Since it is not possible to
monitor all actions held in open environments, a
centralized management should be avoided. Multiagent
systems seem to be a suitable approach to manage trust
due to their distributed nature. We intend agents to
manage trust as humans do, in a vague and abstract way,
as a fuzzy concept. In this paper we extend our previous
works about the representation and communication of
reputation among collaborative agents in competitive
scenarios (as e-commerce applications). Because of the
economical and strategic value of the trust-related
information exchanged in such e-commercial scenarios,
the access to this information should be restricted.
Specifically this paper proposes a secure and fair way to
introduce newcomers protecting newcomers’ privacy as
much as it is possible.
