Cloud storage services such as Dropbox and Google Drive enable individuals and organizations to outsource data storage to remote servers. Cloud storage providers generally adopt data deduplication, a technique for eliminating redundant data by keeping only a single copy of a file, thus saving a considerable amount of storage and bandwidth. However, encryption may nullify the deduplication gain. Moreover, an attacker can abuse deduplication protocols to steal information. In this talk, I will have an overview of security and privacy issues in deduplicated cloud storage services.
