Abstract

Collaborative business can become unreliable in terms of au- thorization policy conflicts, for example, when (1) incorrect role assign- ment or modification occurs in a service within one organization or (2) messages transferred from one organization are accessed by unqualified roles in other collaborating business partners. Therefore reliability veri- fication based on access policies is critical for business collaboration. In this paper, a role authorization model, Role-Net, is developed based on Hierarchical Colored Petri Nets (HCPNs) to specify and manage role authorization in business collaboration and to verify collaboration relia- bility according to partners’ authorization policies.
