Understanding the requirements and limitations of reputation based systems
Abstract
Reputation-management, as proposed for dynamic and open systems aims at providing mechanism for analysing the behaviour of nodes/agents, and distributing this information so that those judged to be acting against the interests of a community can be caught in time, and the impact of their actions limited. We study the assumptions that underpin this decision-making role for reputation-management and highlight its limitations with regard to the incentives required to realise the benefits claimed.
Moreover, we show that such benefits may not be realisable without enforcing tight constraints on the behaviour and the expectations of agents, with respect to the definition of the interaction model in environment, and the incentives such a model presents.
