Transparent Cloud Privacy: Data Provenance Expression in Blockchain

The development of Cloud processing and ‘Big Data’ have raised many concerns over the use to which data is being put. These concerns have created new demands for methodologies, and capabilities which can provide transparency and trust in data provenance in the Cloud. Distributed ledger technologies (DLTs) have been proposed as a possible platform to address cloud big data provenance. This paper examines the W3C recommendation for data provenance PROV and if the blockchain DLT can apply the core primary PROV attributes required to satisfy data provenance. The research shows that not all data provenance expressions can be provided by blockchain. Instances of data provenance which rely on circular references are not possible as the blockchain DLT is a single linked list.
