Data Deduplication: A Technique for Efficient Storage in Cloud

Cloud Computing allows users to outsource storage and computation to servers using internet. In this paper we propose a data Deduplication technique to reduce the amount of storage space and to save bandwidth. The convergent encryption technique has been proposed to protect the confidentiality of sensitive data. Our scheme has the feature of access which allows only valid users to share the data over the cloud storage. Data Deduplication is not only an efficient means of storage over the cloud but also enforces security over the stored data. We ensure that the authorized duplicate check scheme does not create any overhead. The hybrid cloud approach is used for data storage which is very different from the traditional systems.
