The Design and Implementation of Collaboration Service Integration Platform Based on Context-Aware Role Based Access Model

In recent years, the effective management of organization's business processes has become more and more important to support the business workflows. Although some collaboration platforms have been created to support business processes, the user and role authorities in these platforms cannot automatically change in accordance with context information (e.g., time and location, and environment information). Therefore, this study designs and implements the Collaboration Service Integration Platform (CSIP) which combines Business Process Model and Notation (BPMN) and Context-Aware Role-Based Access Control (CARBAC) model. The context information is considered to enhance RBAC and adjust the authority of user role dynamically. For implementation, the logic gateways and connectors are added in the tasks and workflows for adjusting the authority dynamically. The right information can be accessed by the right user in CSIP based on CA-RBAC.
