Fog-assisted data integrity auditing scheme with deduplication function for cloud storage

This academic paper describes a system that combines fog computing (processing data closer to where it's generated rather than in distant cloud servers) with data integrity auditing (checking that stored files haven't been corrupted or tampered with) and deduplication (removing duplicate copies of the same data to save storage space) for cloud storage. The research proposes a scheme that performs these three functions together to improve security and efficiency when storing data in the cloud.
