DESIGN AND IMPLEMENTATION OF A PRIVACY PRESERVED OFF-PREMISES CLOUD STORAGE

Despite several cost-effective and flexible charact eristics of cloud computing, some clients are reluc tant to adopt this paradigm due to emerging security and pr ivacy concerns. Organization such as Healthcare and Payment Card Industry where confidentiality of info rmation is a vital act, are not assertive to trust the security techniques and privacy policies offered by cloud service providers. Malicious attackers have violated the cloud storages to steal, view, manipul ate and tamper client’s data. Attacks on cloud storages are extremely challenging to detect and mi tigate. In order to formulate privacy preserved cloud storage, in this research paper, we propose a n improved technique that consists of five contributions such as Resilient role-based access c ontrol mechanism, Partial homomorphic cryptography, metadata generation and sound stegano graphy, Efficient third-party auditing service, Data backup and recovery process. We implemented these components using Java Enterprise Edition with Glassfish Server. Finally we evaluated our pro posed technique by penetration testing and the results showed that client’s data is intact and pro tected from malicious attackers.
