Integrity Auditing for Secure Cloud Storage on Sensitive Data Protection

Abstract

Users can interchange data with others and remotely store their data on the cloud using cloud storage services. The integrity of data saved in the cloud should be ensured through remote data integrity audits. An electronic health record system is one popular example of a well-known cloud storage system where a cloud file may include unique sensitive data. When a cloud file is shared, private information shouldn’t be exposed. Sensitive information can be realized if the entire shared file is encrypted, but other users cannot access it. How to share sensitive material that is hidden in remote data integrity audits is still up in the air. In this method, data blocks that match sensitive information in the file are sanitized, and the data block signatures are changed to ones that are appropriate for the cleaned-up file. Throughout the integrity auditing process, these signatures are used to verify the accuracy of the cleaned file. Since sensitive information is concealed, our solution permits the sharing and usage of a cloud-stored file by others while maintaining the capacity to conduct remote data integrity audits efficiently.
