Blockchain-Based Data Integrity Verification Scheme in AIoT Cloud-Edge Computing Environment

With the rapid development of Artificial Intelligence of Things (AIoT) technology and applications, the cloud-edge computing system provides convenient and low-latency storage and decentralized computing services to reduce computing requirements in the cloud environment. However, data integrity verification is still an urgent issue researchers have widely discussed in AIoT cloud-edge computing environment. As a distributed and immutable ledger technology, blockchain provides an effective way of data verification in digital financial transactions. The research proposes a blockchain-based data integrity verification scheme to improve the data verification rate in cloud-edge computing environment. Based on the method, a detailed blockchain-based data integrity verification scheme without a trusted third party is proposed with a data upload phase and a data verification phase. The novel proposal system is built on Hyperledger Sawtooth and experimentally evaluated against two state-of-the-art systems in a simulated cloud-edge environment. The results demonstrate that the proposed scheme can efficiently verify data integrity with a high verification rate.
