Privacy Preservation Protocol for Data Storage in Cloud Computing

Abstract

In cloud computing, data owners host their data on cloud servers and users (data consumers) can access the data from cloud servers. However, this new paradigm of data hosting service also introduces new security challenges. Information owners must trust cloud providers for all of their security. Since various protocols are implemented for the security of these cloud data Storage. But there is a need of privacy preserving protocol that should keep owner's data confidential against the auditor and verify the correctness of data and user. The proposed methodology provides a secure, dynamic auditing and privacy preserving protocol for the secure access of the cloud data storage. This methodology is implemented using the hybrid combination of Access Policy and Elliptic Curve based Encryption.
