Preserving Privacy in Public Auditing for Shared Cloud Data

Public auditing, distributed data, cloud computing, privacy-preserving.

A cloud service provider propose a secure, scalable and suitable surroundings for the cloud users at low expenditure. With the help of data storage services, cloud becomes a best location for the data users to accumulate their data into the cloud and also distribute around many users. The great challenge in cloud technology is to maintain the data security and identity privacy of users involved in the public auditing mechanism. The public auditing scheme will expose the secret data content and users identity privacy to external verifiers. To overcome the privacy issue an ORUTA (One Ring to Rule Them All) scheme is used to preserve the privacy of users and
help the auditing process on distributed data that is accumulate in the cloud. ORUTA scheme includes ring signature that is essential to hide the users identity on distributed resources. Using ORUTA scheme, the identity of user on every file is kept under confidential or hidden from external auditors. External auditors are capable to examine the distributed data accuracy without getting the whole file. The ORUTA scheme provides data security and identity privacy of users while auditing the distributed data in cloud.
