Compliance Analysis of Authorization Constraints in Business Process

A novel framework of business process compliance analysis is proposed in this paper, and the proposed framework can process 1)business process authorization and non-business process authorization; 2)delegation of task of business processes; 3)inheritance of roles; 4)separation of duty and binding of duty constraints; 5)statics constraints and dynamic constraints. Authorization graph is proposed to describe the framework, and construct and reduce methods of authorization graph are designed to maintain the graph, then compliance analysis algorithms of authorization graph are proposed. Based on the analysis results, conflict patterns are presented. A set of resolutions for each pattern are provided, and a prototype system is implemented. The framework of authorization constraint compliance analysis, independent of platform, can be widely applied to system security analyzing. The effectiveness of the proposed method is reported by a case study and experiments at the end of this paper.
