Modified Public Auditing with Privacy Preservation for Shared Data in Cloud Computing

Jeur Nagaraj Shrikant | Pavan Kumar ^[39]

Abstract: Cloud data services, it is not only stored in the cloud but also multiple users to share the data across the common. The integrity of data and human cloud hardware/software failures is under suspicion because of the existence of Errors. Public shared data with the existing mechanism on the integrity of the audit will reveal confidential information essentially identity privacy public for verifiers. This paper have a novel privacy protection mechanisms shared data stored in the cloud can offer support to public audit. Shared data is necessary to verify the accuracy of the audit to calculate the metadata exploit ring signatures. These systems are shared with the public to identify each data block signature verifiers which efficiently retrieving the entire file without verifying the integrity of the shared data are kept private. In addition to this mechanism is able to perform multiple auditing tasks simultaneously instead of verifying them one by one and using multiple public verifier to improve the efficiency of auditing task and also using CP-ABE Algorithm between user and cloud server to and the protect user confidential data. The experimental results when sharing data integrity auditing effectiveness and demonstrate the efficiency of this system.
