摘要：Data deduplication is one in every of necessary information compression techniques for eliminating duplicate copies of continuation information, and has been wide employed in cloud storage to scale back the quantity of space for storing and save information measure. To guard the confidentiality of sensitive information whereas supporting deduplication, the merging encoding technique has been projected to encode the info before outsourcing. To raised defend information security, this paper makes the primary conceive to formally address the matter of approved information deduplication. Completely different from ancient deduplication systems, the differential privileges of users square measure additional thought-about in duplicate check besides the info itself. We have a tendency to conjointly gift many new deduplication constructions supporting approved duplicate sign on a hybrid cloud design. Security analysis demonstrates that our theme is secure in terms of the definitions laid out in the projected security model. As a symptom of conception, we have a tendency to implement an epitome of our projected approved duplicate check theme and conduct test bed experiments exploitation our epitome. We have a tendency to show that our projected approved duplicate check theme incurs to kenish overhead compared to traditional operations.
