An augmented RBAC structure for collaborative software development

The enterprise nowadays applies collaborative product development to reduce the product cost and improve new product development efficiency. The same situation is shown in developing a software project where even customers are invited to involve in the process of product development. In terms of data management, the system development in such collaborative environment is increasingly concerned with the problem of access control between users and operations. The problem becomes more complex due to various characteristics of different users and corresponding operations. This paper proposes an augmented role-based access control (RBAC) structure for the software project development dealing with software projects. The structure defines dimensions of workload, time and behavior based on basic RBAC concept. Access control issues that arise in a case of interface development of service software for the elderly are discussed. As a conclusion, recommendations are made for further research on access control of collaborative software development.
