Abstract | This thesis focuses on three aspects (i.e., role-based access control, role-based delegation and privacy-aware access control) of developing a systematic methodology for information sharing in distributed collaborative environments. We develop techniques for setting up secure In role based access control systems (RBAC) permissions are associated with roles, and users are made members of appropriate roles thereby acquiring the roles’ permissions. This greatly simplifies management of permissions. Roles are created for various job functions in an organization and users are assigned roles based on their Delegation requirement arises when a user needs to act on another’s behalf to access resources. Essentially, in a multi-agent system, delegation becomes the primary mechanism With the widespread use of information technology, privacy protection becomes a major concern and it could not be easily achieved by traditional access control models. In this thesis, we propose a privacy-aware access control model with generalization boundaries, which could maximize data usability while, minimizing disclosure of privacy. Moreover, our privacy-aware access control model provides a much finer level of control. Although Hippocratic database enforced the fine-grained disclosure policy through creating a privacy authorization table, but it does not allow to distinguish which particular method is used |
