Abstract


The needs of enterprises to constantly optimize and reorganize the business process have been met by workflow and business process management technology, which also brought lots of benefits and office automation so that the efficiency has been increased, customer service improved and competitiveness enhanced. However, since most of the business process models are based on either process or chart, they turn to be barriers for the relevant operational staff to the undstand, extracte, dig and analyze information, thus the data-centric business process models emerge as the times require. Of course, a variety of new problems occur accompanied with the new technology, among with the access control play quite an important role.This thesis aims to research on access control technology of date-centric business process models. Firstly, the concepts of business process and access control technology have been introducted, and then is a study of the application of various access control technology in the process management system as well as the analysis of problems coming right after.Then, the thesis designed a role-based access control model. It introduces the concepts of task, window, view to realize synchronization between the business flow and authorization flow. It presents the authorization constraint mechanism and authorization rule. Meanwhile, the thesis looks into the task assignment strategy involved in access control at business process and put forward an assignment strategy based on fuzzy set theory.In the following, the thesis focuses on J2EE-based and data-centric business process management system, within which the role-based access control has been realized. The thesis introduces the access control architecture, and describes the realization approach of each functional module in the architecture in detail. It also introduces the main sequences of the access control in the business process management system.In the conclusion, the system is applied to "Shanghai Textile Functional Fabric Public Service Platform". The feasibility and practicability of the access control model in the data-centric business process management system can be proved through the application.
