Abstract

The main issues related to cloud computing implementation are security, privacy, and law-awareness. We consider data protection with law-awareness as the major concern for cloud service providers (CSPs) and their customers. Therefore, we provide Law-as-a-Service (LaaS) for CSPs on our law-aware semantic cloud policy infrastructure. The semantic legal policies in compliance with the laws are enforced automatically at the super-peer to enable LaaS. This allows CSPs to deploy their cloud resources and services without worrying about law violations. Afterward, users could query data from the law-aware super-peer within a super-peer domain. Each query is also compliant with the laws. Policies are shown as a combination of OWL-DL ontologies and stratified Datalog rules with negation for a policy's exceptions handling through defeasible (or non-monotonic) reasoning. Finally, the proof-of-concepts prototype systems have been implemented for an H1N1 pandemic investigation scenario in the semantic cloud to justify our approach.
