Applying secret sharing schemes to service reputation

A successful result of choosing, invoking, integrating and composing services in a collaborative environment depends directly on locating reliable services with respect to their performances, histories, feedbacks from their customers, and generally their reputations. Nevertheless, lacking a secure mechanism to create countable reputation information may lead service providers to exaggerate their performances. We propose to apply threshold schemes under the context of service reputation towards providing an unconditionally secure "reputation" credits and systems for services and their providers. We argue that applying such a secure mechanism for reputation of services is not forgeable. As a result, any service requester was able to rely on valuable reputation information and choose the most reliable services with confidence.
