Privacy preserving BPMS for collaborative BPaaS

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 cloud-based 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.

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 modelling approach. We evaluate the architecture and the presented privacy modelling approach by a use-case from the logistics domain and show their feasibility.

Secure service interaction for collaborative business processes in the inter-cloud

The emergence of a closer relationship between cloud service providers in the cloud computing market is the inevitable consequence of the computing as utility concept. The closer cooperation creates competitive advantages for providers and users of cloud services as well. Capacities and services can be used in a collaborative and flexible way. Despite the numerous potentials of composite cloud services, trust, policy and privacy are the major challenges resulting from the distributed and flexible data handling. The paper derives requirements and solutions in the field of inter-cloud service communication with a special focus on security. The proposed architecture is evaluated with a sample collaborative business process of inter-cloud service interaction.

Automation of Privacy Preserving BPMS in Collaborative Cloud-Based Business Processes

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. In an earlier paper, we have discussed the requirements that a Business Process Management System (BPMS) should meet in order to enable privacy preserving business process as a service. This paper presents the necessary steps for implementing such a BPMS for an architecture to enable management of privacy-preserving collaborative business process.

Foundation for Modular Cloud Logistics.

Logistics service providers are facing the need to collaborate because of ongoing trends like outsourcing and concentration on core competencies. The paradigm of cloud logistics promises to make collaboration in the logistics domain more easy and more flexible by adopting the principles of cloud computing to the logistics domain. To ensure the success of cloud computing to the paradigm of cloud logistics as well, standards have to be developed. With the help of the service blueprinting method, a basic logistics module is developed in order to lay a foundation for cloud logistics.

Evaluation of User Specific Privacy Policy Architecture for Collaborative BPaaS on the Example of Logistics

Nowadays, collaboration between multiple companies along the supply chain is one of the key factors for ensuring sustainable success. Although this fact is known by almost all companies the actual collaboration is quite low because of the fear of losing sensitive and critical data to competitors. To solve this problem an architecture for modeling and execution of privacy preserved business processes and a privacy modeling approach have been developed. This paper evaluates both artifacts. The used method is framework for evaluation in design science (FEDS).
