Abstract:
This study focuses on collaborative activities that are best accomplished by organized groups of healthcare practitioners within or among healthcare organizations with the objective of accomplishing a specific task (a case of patient treatment). In our previous work, we proposed an access control model (work-based access control (WBAC)) that is suitable for collaborative healthcare systems in terms of addressing the issues of information sharing and information security. The current study extends on that work by demonstrating and implementing the WBAC access policy for a collaborative healthcare environment to support diverse domains of data authorization management with various constraints. The implementation is based upon using eXtensible Access Control Markup Language (XACML) with SunXACML. We explain the WBAC model for cooperative healthcare systems, introduces a software structure for WBAC implementation, implement the WBAC profile using XACML 2.0, specify permissions and define all authorization policies. Also, we validate the model and compare it with the existing solution to ensure that the model can fulfill and satisfy the main intended objectives. The experimental results demonstrate the efficiency and scalability of WBAC approach. It shows how the WBAC model simplifies decentralized administrative tasks (e.g., changing of team members and shifting responsibilities), thus enhancing the practicability of access control in dynamic collaboration environments.
