Annotation-based access control for e-Professionals

Collaborative Working Environments (CWE) provide shared workspaces that enable eProfessionals to work together and share resources that they own. Most current shared workspaces provide coarse-grained role-based access control policies which bring the functionalities of shared workspaces under question. In this paper, we present Annotation-Based Access Control, an approach towards access control which benefits from user annotations to annotate eProfessionals using various fixed and desired open vocabularies (tags) and helps to build a more flexible access control mechanism based on relationships among eProfessionals (or people). We also present our prototype, a gadget, which we have developed to enable this access control mechanism and evaluate it.
