Secure De-Duplication of Data on Hybrid Auditing

The amount of data stored in storage devices are increased rapidly, as the evolution of networking techniques emerges.While storing huge amount of data, the storage servers ,may want to reduce the volume of the stored data, and the clients may want to check the integrity of their own data through low cost, since the cost of the functions related to data storage increase in proportion to the size of the data.To achieve these functionalities, privacy preserved deduplication and auditing techniques have been studied, which can reduce the volume of data stored on the server by eliminating duplicated copies and allows clients to efficiently verify the integrity of the stored files by delegating costly operations to a trusted party, respectively.We design a technique which performs both secure deduplication of encrypted data and hybrid integrity auditing of data which is stored on the storage devices.We utilize a Third Party auditor(TPA) for performing dynamic audit, in order to help the clients.The proposed scheme provides all the fundamental security requirements through cloud storage server.
