Cloud based privacy preserving collaborative business process management

Through the outstanding efficiency and the general success of cloud computing, cloud-innovations have become an everyday part of the industry. Almost every company has defined business processes to organize its business. The next logical step is to bring business processes to the cloud to exploit the benefits of the cloud and to enable the companies to collaborate with each other in one business process. Such collaborations demand for outstanding privacy and security that has to be provable easily at every time. Every company needs to be able to define its own privacy policies and wants to be able to monitor the compliance with these policies. In this paper we present an approach for privacy preserving cloud based collaborative business process management including an architecture and a privacy modeling approach. We evaluate the architecture and the presented privacy modelling approach by a use-case from the logistics domain and show their feasibility.
