Collaboration-oriented information flow analysis and control for Mobile Cloud

This paper presents a functional design of a `information flow analysis' service that provides information/data owner with a explicit and end-to-end provenance recording of information/data usage and redissemnation among entities in a collaborative context of Mobile Cloud. The core idea is to identify data exchanged among nodes in the business process. BPEL-defined business process is used as a study case. Experiments show the service to scale well with complex processes and to have trivial performance impact when deployed with an orchestration service.
