Data deduplication is one of important data compression techniques for eliminating duplicate copies of repeating data and has been widely used in cloud storage in order to minimize the amount of storage space and save bandwidth. For protection of data security, this paper makes an attempt to primarily address the problem of authorized data deduplication. To protect the confidentiality of important data while supporting deduplication, the convergent encryption technique has been proposed to encrypt the data before outsourcing.
