Removing Duplication Data in Cloud with Secure Accessibility
B.Shireesha · Journal of Emerging Technologies and Innovative Research · 2018
In recent days, cloud computing offering various resources over Internet. Among those resources, one of the important services is data storage. In order to preserve the privacy of users, the data is stored in cloud in an encrypted form. Deduplication becomes crucial and a challenging task when the data is stored in encrypted form, which also leads to complexity in storing large data and processing in cloud. A traditional deduplication method does not work on encrypted data. Existing solutions available for deduplicating encrypted data has various security issues. Cloud does not provide access control and revocation in terms of storage. Hence, the deduplication schemes are not mostly deployed in practice. In this paper, we propose a technique to deduplicate encrypted data stored in cloud based on access control, thereby avoiding redundant storage. It integrates cloud data deduplications with access control. The result of our scheme shows superior efficiency and has potential for practical deployment in the case of huge data storage. We will retrieve files based on fast keyword searching and at the time of downloading will provide security for the file with keys.
