Privacy Preserving BPMS for Collaborative BPaaS

Abstract

Abstract-Collaboration in business environments is an ongoing trend that is enabled by and based on cloud computing. It supports flexible and ad-hoc reconfiguration and integration of different services, which are provided and used via the internet, and implemented within business processes. This is an important competitive advantage for the participating stakeholders. However, trust, policy compliance, and data privacy are emerging issues that result from the distributed data handling in cloud-based business processes. Up to now, several architectures and technical systems that enable the cloud-based collaboration within business processes have been developed, but the selection of an appropriate business process management system (BPMS) is missing. An implemented BPMS has to meet certain requirements that result from the cloudbased characteristics and from the other implemented systems. This paper derives requirements for BPMSs in cloud-based environments, currently available BPMSs are evaluated against the derived requirements and the selected one is implemented subsequently.

Confidentiality Enhanced Life-Cycle Assessment

“…As our runtime evaluation shows that the actual computation has only little impact on the runtime of our approach, we expect our approach to work equally well with the various LCA variants. Outside of the LCA domain, there are works integrating privacy enhancing technologies (such as SMPC) in the execution of business processes (e. g., [16,21,22,24,28]). Similar to our work, they present domain specific adaptions of these technologies to solve a particular informationsharing problem.…”
