Abstract

In this paper, the authors proposed an effective, efficient and flexible distributed strategy with explicit dynamic data support to ensure the accuracy of users’ data in the cloud. In file distribution preparation, to provide redundancies and assure data dependability and reliability, erasure correction code is used. This construction leads to extreme reduction in the communication and storage overhead as compared to the traditional replication-based file distribution techniques. Data deduplication is one of the essential data compression techniques for eliminating or exterminating duplicate copies of repeating data, and is extensively used in cloud storage in order to save bandwidth and reduce storage space. To provide better data security, in this paper the authors address the problem of authorized data deduplication. Here several new de-duplication constructions which support authorized duplicate presented. Security analysis demonstrates that the proposed scheme is secure in terms of the definitions specified in the proposed or security model. As a proof, the prototype of proposed authorized duplicate check scheme is implemented and experiments are conducted using the prototype. The proposed authorized duplicate check strategy incurs minimal overhead compared to normal operations.
