Secure Information Sharing within a Collaboratory Environment

An Early Career PI Project

Information sharing on the Internet usually occurs in broad, highly dynamic network-based environments, where formally accessing the resources in a secure manner poses a difficult challenge. In collaborative sessions protection of contextual information and resources entails addressing the unpredictability of users and the unexpected manners in which users and applications interact. This project is investigating how to enhance information sharing in collaborative environments.

The goal is to enable users to access and selectively share resources in distributed database systems.

The objectives of this project are

• Develop a rule-based framework for role-based delegation.
• Implement a proof-of-concept of this framework.
• Investigate identity management and proactive protection of collaborative environments.
