Review on Preserving Privacy Public Auditing for Regenerating-Code-Based Cloud Storage
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 10
Abstract
Cloud computing becomes popular for data owner to outsource their data to public cloud server while allowing data users to retrieve this data whenever he need it. Regenerating codes have lower repair bandwidth to provide fault tolerance. To protect data stored at cloud server against corruptions with data integrity checking becomes critical. Existing remote checking methods only provide private auditing, requiring data holder to always stay online and handle auditing, as well as repairing, which is not possible. This system proposes a public auditing scheme in which any external auditor can audit user’s outsourced data in the cloud without understanding the knowledge on the data content. To preserve data privacy our system, randomize encode coefficients with a pseudorandom function and data owner upload files in encrypted format so that auditor cannot see actual data. Auditor able to efficiently check the cloud data integrity and introduce no additional burden on data owner to always stay online. Also recovering data using proxy server. Extensive security and performance evaluation shows that the proposed schemes are provably scalable, secure, and highly efficient.
