Protecting Information Sharing in Distributed Collaborative Environment

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 group communication and providing accesses to group members for many database systems, which incorporate new security co...

Load Sharing in a Distributed Environment

A network of UNIX [Ritchie, 1974] workstations is becoming a common sight in modern computing environments. Each workstation provides powerful computing resources which are periodically in strong demand by the local user. However even in busy environments, a significant proportion of these machines will be idle or underutilized at any one time. By supplementing the local computing resources thr...

Learning through Collaboration in a Distributed Education Environment

This paper describes how the Computing Department of the Open University is using the Internet for collaborative learning in a distributed educational process. Our research has been to see the extent to which traditional communications media can be replaced by electronic communication for the whole educational process and in particular to assess the role of collaborative learning in a distribut...

An Analysis of Design and Collaboration in a Distributed Environment

The Swedish MultiG program addresses research issues in distributed multimedia workstation applications, including CSCW, and high-speed networks. This report treats some basic CSCW issues in a distributed design environment. We review and analyse relevant literature on system design and computer supported cooperation and discusses the basic issues: What is design?What is collaboration in design...
