On Data Provenance in Group-Centric Secure Collaboration
In this paper, the authors explore data provenance in a group-centric secure collaboration environment. In collaborations, participating organizations are likely to want certain trustworthiness on the data that are shared from other organizations and some assurance on how the shared data are used by users regardless of their organizations. By utilizing data provenance in group collaboration environment, they can provide the participating organizations with various provenance information that can establish trustworthiness and assurance on the shared data. To achieve this, they first identify what kind of operation information can be and should be captured as provenance data and how this information can be expressed in a formal representation which can be queried via the provenance system for certain utilities.
