Secure collaboration based on RBAC in decentralized multi-domain environments

Advance technologies in decentralized systems are the new building block of today's Internet and provide interoperability among heterogeneous databases. In these environments, interoperation and information sharing are one of the most critical issues. Interoperability enables users to access database in different domain. Furthermore, government, financial and medical institutions more require secure collaboration to share their data with organizations. However secure collaboration has many challenging problem in multi-domain environments. In this paper, we propose secure collaboration to effectively share resource by reconcilement structure. Proposed scheme is based on Role Based Access Control (RBAC) to support flexible control. In decentralized RBAC-based system, the number of roles can be in the hundreds or thousands and they share information among dispersed domains. We present solution which regulates the interoperability.
