Abstract
Collaborative Working Environments (CWEs) are getting prominence these days. With the increase in the use of collaboration tools and technologies, a lot of sharing and privacy issues have also emerged. Due to its dynamic nature, a CWE needs to adapt the changes into accordingly. In this paper, we have implemented the Adaptive Dynamic Sharing and Privacy-aware Role Based Access Control (Adaptive DySP-RBAC) model which provides user’s information privacy to dynamically adapt the changes occurring in the system at any time. The proposed model has been implemented as a prototype and tested. Results have shown that our system efficiently and effectively adapts access rules according to the changes happening in a CWE along with preserving the user’s information privacy in the system.
Highlights
Today, mutual teamwork-based working environments and cooperation among the members have gained prominence
People without working together at the same place can collaborate with each other. This type of working environments is known as Collaborative Working Environment (CWE)
There are 4500 access control permissions which are used in sets of 1500, 3000, and 4500 permissions to test the system with increasing number of permissions
Summary
Mutual teamwork-based working environments and cooperation among the members have gained prominence. People without working together at the same place can collaborate with each other. This type of working environments is known as Collaborative Working Environment (CWE). With the help of CWE, people can share their ideas, efforts, results, inventions etc. At the same time, they can change their locations as well. A lot of work has been done in order to improve CWEs. In [1], seven different collaboration factors related to collaboration have been discussed. A collaborative working model has been presented by summarizing all those factors. With the increase in the use of CWEs, the need for privacy preservation and access control has increased
