Secure information deduplication will considerably scale back the communication and storage overheads in cloud storage services, and has potential applications in our massive data-driven society. Existing information deduplication schemes area unit usually designed to either resist brute-force attacks or make sure the potency and information accessibility, however not each conditions. we tend to also are not conscious of any existing theme that achieves responsibility, within the sense of reducing duplicate data revealing (e.g., to work out whether or not plaintexts of 2 encrypted messages area unit identical). during this paper, we tend to investigate a three-tier cross-domain design, associated propose an economical and privacy-preserving massive information deduplication in cloud storage (hereafter mentioned as EPCDD). EPCDD achieves each privacy-preserving and information accessibility, and resists brute-force attacks. additionally, we tend to take responsibility into thought to supply higher privacy assurances than existing schemes. we tend to then demonstrate that EPCDD outperforms existing competitive schemes, in terms of computation, communication and storage overheads. additionally, the time quality of duplicate search in EPCDD is power.
