Users can use cloud storage services to remotely store their data and enable data sharing with others. Remote data integrity verification is advised in order to guarantee the accuracy of data saved in the cloud. Some prominent cloud storage platforms, like the electronic medical record system, may have files with sensitive data on them. Confidential information shouldn't be made available to others while sharing a cloud file. The entire shared file can be encrypted to protect sensitive information, but doing so prohibits others from accessing it. It is still unknown how sensitive data sharing with distant data integrity checks will be carried out. We recommend a remote data integrity verification method that implements the sharing of sensitive data hidden in this study to address this issue. This method uses a cleaner to make data block signatures valid for the file being processed while cleaning data blocks that correspond to sensitive data in the file. In the integrity check phase, these signatures are used to verify the correctness of the cleaned file. As a result, our method allows you to share and access a file stored in the cloud while sensitive data is masked, while you can efficiently perform remote data integrity checks.
