L'Elimination de la subjectivite dans la recommandation de confiance

摘要

In ubiquitous environments, a party who wishes to make a transaction often requires that it has a certain level of trust in the other party. It is frequently the case that the parties are unknown to each other and thus share no preexisting trust. Trust-based systems enable users to establish trust in unknown users through trust recommendation from known users. For example, Bob may choose to trust an unknown user Carol when he receives a recommendation from his friend Alice that Carol's trustworthiness is 0.8 on the interval [0, 1].
