User specific privacy policies for collaborative BPaaS on the example of logistics

Today's business is more and more organized in collaborative networks. Although decision makers know the benefits of collaboration, they are afraid of losing control of their data, which is one of the main impediments for Cloud Computing. We propose a novel cloud based approach for collaboration in business processes with guaranteed control of the privacy of the data. The platform ensures the compliance with the companies' privacy policies and laws. The paper shows the definition of privacy policies and how they are converted into a well established access control language. An example helps to clarify the methods.
