Abstract: Role-based Access Control (RBAC) has been widely used as an international norm, but it can only give users authority to operate a particular operating environment issues, and it cannot be used to solve the access control problems of different subsets of operating objects under same conditions. Especially in the workflow system, access control of different set of objects, and different nodes is particularly important. To address this problem, role-based access control technique and workflow technique were studied. An access control model of workflow permissions was proposed based on group/role, which achieved two-dimensional operation set access control permissions. It is a better solution to the cross-regional case, the multi-sector work-based workflow system object access control and access control problems. Currently, the model has been used in the construction of oilfield integration system, and the application shows that the model is scientific, reasonable and feasible.
