“…We coincide in both works in prevailing characteristics of data integrity, blockchain technology, auditing and traceability services, and implementing the microservice architecture. However, reference [35] focuses exclusively to supply chain systems resulting in very bounded implementations, so, in this work, we decide to include a more generalized solution for cloud systems. In contrast with [35], our proposal starts with the security suggestion of [36] concerning the auditing mechanism from when a Root user is created in a decentralized environment.…”

“…A closely related work is presented in [35], an audit mechanism that saves all the events of a supply chain in a blockchain in a hashed form; then users of the supply chain system can query integrity, data provenance, and traceability from a blockchain through an intermediate server that establishes communication between blockchain and the supply chain. Recently, RootLogChain was proposed in [36], it is an audit mechanism that is built upon a security protocol to create a root user in a blockchain, and from there, all root events are stored as logs within a blockchain.…”

A Cloud Microservices Architecture for Data Integrity Verifiability Based on Blockchain

The current digital age, mainly characterized by an economy based upon information technology, demands a data integrity service, even more so because organizations and companies are migrating their services over the cloud. This is not a simple task; it is cumbersome since traditional schemes in databases could be subject to modifications. However, it can be solved using blockchain technology. This paper provides a data integrity verifiability architecture for cloud systems based on blockchain. The architecture provides a mechanism to store events (as logs) within a blockchain platform from any cloud system. Users can then consult data integrity through a microservice, acting as an intermediate server that carries out a set of verification steps within the blockchain, which confirms the integrity of a previously stored log. Our architecture takes advantage of the blockchain strength concerning integrity, providing a traceability track of the stored logs. A prototype system and a case study were implemented based on the proposed architecture. Our experimental results show that the proposed decentralized architecture can be adapted to cloud existing systems that were born without blockchain technology and require a modular and scalable audit characteristic.
