Data deduplication is one of important data compression techniques for eliminating duplicate copies of repeating data, and has been widely used in cloud storage to reduce the amount of storage space and save bandwidth. To protect the confidentiality of sensitive data while supporting deduplication, the convergent encryption technique has been proposed to encrypt the data before outsourcing. Different from traditional deduplication systems, the differential privileges of users are further considered in duplicate check besides the data itself. The authors also present several new deduplication constructions supporting authorized duplicate check in a hybrid cloud architecture.
