In this paper, the existing workflow technology and access control model are fully studied, based on the TRBAC model of the most suitable workflow management system, some improvements are made to the model from the angle of application. This model introduces the role concept of role-based access control into task-based access control, the core idea of which is to enable the user to access the data by acquiring a role (but the authorization step that contains the permission must be activated, otherwise the role's permissions will be frozen). The access control model can simulate the management hierarchy in real environment, it solves the problem of low flexibility of access control, and uses the concept of "workflow" to restrain the role, change the passive mode of "subject-object" in traditional access control, and realize the active control of access rights, Make it more suitable for access control implementation in distributed environment. In this paper, the "role-task" based access control model is applied to the personnel Management system, explore the practical platform as a service (PaaS), and create a secure data access environment for the cloud based information system, and verify the usability and effectiveness of the role-task access control model.
