Secure Storage Optimization using Cloud
Prajakta B. Mane, Prof.N. B. Pokale · 2015
An increasing amount of data is being stored in cloud-based storage services and this trend is expected to grow in the coming years. Data de-duplication becomes more and more a necessity for cloud storage providers. Cloud storage services commonly use duplication, which is useful in storing only a unique file or block by eliminating duplicate copies of data. De-duplication is helpful in saving network bandwidth and storage space which is an advantage to the users or clients in cloud. The proposed scheme in this paper not only the reduces the cloud storage capacity but also improves the speed of data de-duplication. To protect confidentiality of sensitive data while supporting de-duplication the encryption technique has been proposed to encrypt the data before outsourcing.
