TEES: An Efficient Search Scheme over Encrypted Data on Mobile Cloud

TEES: An Efficient Search Scheme over Encrypted Data on Mobile Cloud Data privacy is a growing challenge in cloud computing, as the users data are uploaded on a third party cloud. To preserve data privacy for user uploaded data, the data is encrypted and stored in cloud server. When the user request for data, it can be downloaded and decrypted from user side. Data encryption incurs high overhead, which make it necessary to find an efficient search scheme. Existing technique uses, single keyword search on encrypted data, in which user…

Secure Data Deduplication with Dynamic Ownership Management in Cloud Storage

Secure Data Deduplication with Dynamic Ownership Management in Cloud Storage In cloud storage services, deduplication technology is commonly used to reduce the space and bandwidth requirements of services by eliminating redundant data and storing only a single copy of them. Deduplication is most effective when multiple users outsource the same data to the cloud storage, but it raises issues relating to security and ownership. Proof of-ownership schemes allow any owner of the same data to prove to the cloud storage server that he owns the data in a robust way.…
