Reference Architecture for Trust-Based Digital Ecosystems

Formation of digital ecosystems enables a multitude of actors like organisations, users and developers to achieve different goals in cooperations. The achievement of operational, tactical and strategic goals of involved actors relies on trustworthy cooperation of systems that operate in open environments and might meet for the first time at runtime. Thus the evaluation of a potential collaborator's trustworthiness also needs to be performed at runtime. In this paper, we enhance our work on trust prediction in digital ecosystems, based on digital twins evaluation, with a supporting reference architecture that enables the creation of such a digital twin for automatic computation of trust.
