Sistema de Reputação Orientado a Serviços baseado em Lógica Nebulosa

Alexandre Gomes LagesFlávia C. DelicatoLuci Pirmez

In the current Web environment users are able to directly interact to exchange data and services, without intermediation of central authorities. Such scenarios raise the need of efficient systems to assure the safety and confidence of transactions. Reputation Systems, which are widely used in P2P networks, have the goal of individually evaluating peers, relying on their previous interactions in the network. Reputation Systems could be used to increase the security on a service level. We propose the use of a service-oriented reputation system based on fuzzy logic as a solution to increase the security on a service level. This paper presents the description of the proposed system and the simulations carried out to evaluate it.
