Abstract:
The advent of Cloud computing supports the offering of many Business Process Management applications on a
distributed, per-use basis environment through its infrastructure. Due to the fact that privacy is still an open
issue in the Cloud, many companies are reluctant to move their Business Processes on a public Cloud. Since the
Cloud environment can be beneficiary for the Business Processes, the investigation of privacy issues needs to
be further examined. In order to enforce the Business Process sharing on the Cloud we propose a methodology
(“BPELanon”) for the anonymization of Business Processes expressed in the Web Service Business Process
Execution Language (BPEL). The method transforms a process to preserve its original structure and run-time
behavior, while completely anonymizing its business semantics. In this work we set the theoretical framework
of the method and define a five management layers architecture to support its realization. We developed a tool
that implements the
“BPELanon” method, validate its functionality and evaluate its performance against a
collection of real-world process models that were conducted in the scope of research projects.
