TIDE: measuring and evaluating trustworthiness and credibility of enterprises in digital ecosystem

In this paper, we investigate the effectiveness and appropriateness of several existing trust management systems for a Digital Ecosystem (DE) environment. DE is characterized as an open and dynamic environment where the interaction and collaboration between its entities are highly promoted. A major requirement to promote such intensive interaction and collaboration is the ability of an entity to measure the trustworthiness of other entities in performing honest transactions. However, most of the proposed trust management solutions do not provide an adequate mechanism for computing the trustworthiness values into its exact measurement. In addition, the appropriateness of these solutions to meet the unique DE characteristics is still in deficient level. Therefore, we propose a distributed trust model for individual enterprises to effectively derive the trustworthiness value of an entity. This would allow them to decide which entities are trustworthy and which entities are not. This model also allows the enterprises to progressively understand the credibility of their recommender entities.
