Supporting Trusted Data Exchanges in Cooperative Information Systems

In cooperative processes and in e-services, an evaluation of the quality of exchanged data is essential for building mutual trust among cooperating organizations and correctly performing cooperative activities. Several quality dimensions, related to the intrinsic nature of data and to the context of the cooperative process where data are used, must be taken into consideration. In addition, in order to accomplish a trusted cooperative environment, data sensitivity parameters must be taken into account. A model for data quality in cooperative information systems and e-applications is proposed, together with an architecture for trusted exchanges of data and quality information associated to it. Strategic use of the model and of the architecture is discussed.
