Abstract: Many techniques are using for the elimination of duplicate copies of repeating data, from that techniques, one of the important data compression technique is data duplication. Many advantages with this data duplication, mainly it will reduce the amount of storage space and save the bandwidth when using in cloud storage. To protect confidentiality of the sensitive data while supporting de-duplication data is encrypted by the proposed convergent encryption technique before out sourcing. Problems authorized data duplication formally addressed by the first attempt of this paper for better protection of data security. This is different from the traditional duplication systems. The differential privileges of users are further considered in duplicate check besides the data itself. In hybrid cloud architecture authorized duplicate check supported by several new duplication constructions. Based on the definitions specified in the proposed security model, our scheme is secure in terms of definition and implementation.
Keywords: Deduplication, authorized duplicate check, confidentiality, hybrid cloud, convergent encryption, symmetric encryption.
