Privacy Preserving and Storage Optimization on Cloud

Prajakta B. Mane | N. B. Pokale ^[6]

Abstract: 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 deduplication 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. Deduplication 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 deduplication. To protect confidentiality of sensitive data while supporting deduplication the encryption technique has been proposed to encrypt the data before outsourcing.
