Abstract

In Forthcoming times of information technology companies, cloud computing updated as the structural model. There are so many benefits of cloud computing in technical as well as in organization. But still there are many new objections will carried in cloud computing for example in data security in cloud storage. There are many approaches available for data security in cloud storage like encryption with obfuscation technique, watermark security, data partitioning technique. In above all the approaches, there is no possibility that cloud data centers are operate computation on encrypted data so every time if user wants to modify data, it is necessary to decrypt data. The most used technique for providing security in cloud storage is Homomorphic encryption. In the homomorphic encryption technique, there is no need to decrypt whole data whenever user wants to update data. In the existing system used the mixed homomorphic scheme which reduce noise level in homomorphic encryption technique. The existing system focus on data corruption and data modification but what if system failure and power failure occurs. The user data may be loss in any reasons and user may not have any copy of data. The Existing system not focus on data loss. So in proposed work focus on availability of data by erasure code. By applying the erasure code if in any case user data is loss, will be reconstructed which provide more security than existing system.
