Secure Auditing and Hybrid Deduplication Data in Cloud Computing systems

Abstract

Cloud Storage are becoming more and more popular these days and hence they require the mechanism to down their utilization cost and provide more efficiency and security to client’s data.  Hybrid Deduplication is the technology which stores only a single copy of data and so it reduces the required storage space. In order to provide confidentiality to the client’s data at the same time acquiring data deduplication, so we provide a technique called symmetric encryption. In this, data encrypted before outsourcing. To provide better data security this first talks the problem of authorized data Hybrid deduplication, also we have presented several security schemes for data deduplication   construction in a Cloud Computing Technology Models. The proposed method shows that the users to achieve both data integrity and storage efficiency, results in non-trivial duplication of metadata (i.e., authentication tags), which contradicts the objectives of POW protocol implementation. Recent attempts to this problem introduce tremendous computational and communication costs and have also been proven not secure. Our Proposed Architecture allows Hybrid deduplication of both files and their corresponding authentication tags. Data integrity auditing and storage deduplication are achieved simultaneously.  Analysis and Experimental results on different systems shows that our scheme is efficient and scalable.
