Now-a-days, data deduplication is one of the relevant data compression techniques for removing duplicate copies of repeating data, and has been broadly used in cloud storage to reduce the amount of storage space and save bandwidth. To defend the privacy of sensitive data while supporting unrepeatable, the convergent encryption procedure has been suggested to encrypt the data before outsourcing. To well protect data confidence, first attempt to officially address the problem of authorized data deduplication. Dissimilar from out-of-date deduplication organizations, the variance rights of users are further considered in duplicate check besides the data itself.
