Abstract: For the complex modeling problem caused by the complex communication,interaction and collaboration between multiple organizations in the collaborative business process,a view-basedapproachforcollaborative business processes was proposed.The private view was defined,and the control flow of private view was maped into a tree structure.Based on the tree structure,the migration technology for each of the four relational nodes was proposed.On this basis,the private view was migrated to the public view,and then a modeling method for constructing a collaborative business process was proposed,by which the collaborative business process constructed was theoretically proved to be correct.By modeling actual case and comparing them with existing typical methods,the analysis results showed that the proposed method could improve the privacy protection under the premise that the correctness of the collaborative business process before and after the migration was consistent and the modeling efficiency was not affected.
