A Blockchain-Based Multi-Cloud Storage Data Auditing Scheme to Locate Faults

Cheng Zhang et al.

Summary: This article introduces a blockchain-based multi-cloud storage data auditing scheme to ensure data integrity and resolve service disputes. The scheme utilizes blockchain to record interactions between users, service providers, and organizers as evidence, and employs smart contracts to identify malicious service providers. Theoretical analysis and experiments demonstrate the effectiveness and acceptable cost of the scheme in multi-cloud environments.

A Blockchain-Based Public Auditing Protocol with Self-Certified Public Keys for Cloud Data

Hongtao Li et al.

Summary: This paper proposes a public auditing protocol with a self-certified public key system using blockchain technology, which ensures the security of auditing data source by putting the user's operational information and metadata information of the file into the blockchain. The scheme has been improved in terms of storage overhead, communication bandwidth, and verification efficiency compared to other public auditing schemes.

A Blockchain-Enabled Deduplicatable Data Auditing Mechanism for Network Storage Services

Yang Xu et al.

Summary: This article proposes a blockchain-based deduplicatable data auditing mechanism, which designs a client-side data deduplication scheme using bilinear-pair techniques to solve the problems of high cost and reliance on trusted third parties in traditional approaches. By utilizing both blockchain technique and bilinear pairing cryptosystem, a trustworthy and efficient data auditing mechanism is achieved to ensure data integrity.

Blockchain-Based Public Integrity Verification for Cloud Storage against Procrastinating Auditors

Yuan Zhang et al.

Summary: The deployment of cloud storage services brings significant benefits in data management for users, but also raises security issues, such as data integrity. Public verification techniques can help users employ third-party auditors to verify data integrity, but existing schemes are vulnerable to procrastinating auditors. CPVPA is a certificateless public verification scheme using blockchain technology to address this issue, requiring auditors to record verification results in transactions on the blockchain.
