Research on cloud storage data integrity verification protocol based on smart technologies

With the continuous development of digital economy and Internet of Things technology, it has brought huge benefits to people and generated massive amounts of data. As a result, users migrate their data to the cloud. Cloud storage not only provides a large amount of storage space and low storage costs for user data, but also provides users with more convenient access methods and more flexible capacity scalability. However, moving data to the cloud brings many benefits as well as security and integrity issues, which contains the data corruption, unauthorized access, and sensitive information compromise. In this work, we proposed a novel verification process to check the integrity of data in the cloud storage platform without revealing any sensitive information. The model uses block-chain technology to provide a decentralized verification mechanism in this protocol, ensuring the integrity of data by creating an immutable and transparent chain of records. As for data change or access is recorded on the block-chain, providing a verifiable, tamper-proof history of data that builds trust across the system. From our extensive experiments, we can observe that our proposed can achieve the verification process with reasonable protocols and acceptable computation costs.
