Trust plays an important role in decision making especially in cases of uncertainty and incomplete information. There are many challenges to trust calculation. In this paper, we identify the challenges and offer a middleware solution. Our solution consists of a SCOUT middleware and a SCOUT client (Trust Calculator) that can be used by an application to facilitate trust calculation. As validation, a scenario is implemented. The scenario consists of service selection based on trust calculated by our proposed solution.
