One of the difficulties in evaluating the trustworthiness of an object in a virtual organization is the lack of sufficient information to study how the object was formed and to what level its components should be trusted. If a subject could be provided with detailed information about the ingredients of a compound object, then the subject would be able to evaluate the trust level of that compound object with higher confidence. This paper introduces a scheme using labels associated with each object within the domain of a virtual organization to facilitate trust management. Each label supplies certain information regarding the originality of the associated object. Thus, partial trust (also called component trust) can be integrated to evaluate the composite trust of the compound object. Re-labeling enables object information update to accommodate the dynamic nature of a virtual organization. Indirect trust between two subjects can be calculated based on a trust network. Different subjects may view the same object with different trust values because they trust the components of the object to different degrees. This model uses recommendations supplied by other subjects to provide a dynamic and flexible way to adjust the trustworthiness of an object for a certain subject.
