In this paper, the authors present a trust model to evaluate the trustworthiness of information as well as the information publishing nodes based on the information provenance. They consider two factors in evaluating the provenance based information trust: path similarity and information similarity. In multihop networks, information can flow through multiple hops and in multiple paths. They model the similarity factor between different paths which deliver information about the same event. They also model the similarity between two information items delivered through different paths about the same event. Both path and information similarity factors are considered in determining the trust on the information.
