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.
