ABSTRACT

Consensus method and highly programmable smart contracts automatically perform secure data sharing for dynamic audits. One of the most significant developing technologies at the moment is blockchain technology. With regard to traditional cloud audit data in central storage, vulnerability, tampering, incomplete transmission, and unsafe data flow, its characteristics of decentralization, non-tampering, traceability, and high security may effectively address these issues. Blockchain technology can speed up data compilation and enhance the accuracy of audit findings. According to this concept, a Consortium blockchain is created for various auditors, and only users who have identity compliance through the node admission method are permitted to exchange cloud auditing data. For diverse audit data with varying ownership structures and levels of sensitivity, off-chain asynchronous safe storage is employed. In the proposed task, the auditor is required to start a new transaction for each verification, conduct the transaction, and incorporate the verification-related data into the transaction. The user can check the transaction's creation time to see when the auditor performed the verification after the transaction was added to the blockchain.
