Abstract

We provide a defence against whitewashing for trust assessment mechanisms (TAM) by using an underlying social network in MAS and P2P. Since interaction requests are routed through the social network, routers can block requests from portions of the network known for whitewashing. Furthermore, by limiting feedback spread to the interaction routers, the trust assessment can be done without querying for feedback with a small loss in efficiency.
