Blockchain-enabled Data Provenance in Cloud Datacenter Reengineering

Abstract

Cloud datacenter reengineering has become an emerging technical term along with the rapid growth of cloud computing. There are a few reasons for implementing cloud reengineering. One of the key driven forces of adopting cloud reengineering is that securing data provenance is a major restriction for most contemporary applications. Many cloud-based applications require multiple cloud vendors' collaborations, such that data usage can be rarely controlled or governed during the data life cycle. This work focuses on the issue of data provenance in cloud computing and proposes an approach that uses blockchain techniques to achieve data tracing for a full data life cycle. The proposed method em- phasizes tracing data transfers between cloud datacenter. The data regeneration also is concerned by the proposed approach. Our experiment evaluation has assessed the efficiency performance of our approach.
