Method for supporting a reputation mechanism in a network including one or more domains with one or more users being connected to the domains, one or more Identity Providers that manage identity information, and at least one entity that functions as Web Service Consumer for the users. When a user requests a Web Service Consumer of one of the domains for a web service provided by a Web Service Provider, the requested Web Service Consumer requests its known Identity Providers regarding a recommendation of the Web Service Provider. The Identity Providers function as recommendation aggregators by collecting reputation assessments of the Web Service Provider from entities registered on the Identity Providers who return an aggregated recommendation to the requested Web Service Consumer that determines a trust assessment about the Web Service Provider. A privacy homomorphism is employed for providing an encrypted exchange of recommendation related information.
