Abstract:
Identity Privacy of the outsourced data from public auditing is modelled as privacy issue in the cloud data service during the public auditing. With cloud data services, it is ordinary place for data to be not only stored in the cloud, but also shared across numerous users. Regrettably, the integrity of cloud data is focus to cynicism due to the prolongation of hardware/software failures and human errors. We propose a novel privacy-preserving mechanism that supports public auditing on shared data stored in the cloud. Yet, issues such as risks of privacy exposure , scalability in key management, flexible access and efficient user revocation, have remained the foremost challenges towards achieving fine -grained ,cryptographically enforced data access control. In particular , we exploit and explore multi authority attribute based encryption to compute verification of the data stored in the cloud to audit the correctness of shared data. Through imposing the multi authority-ABE technique our mechanism, the identity of the attribute on each block in shared data is kept private from public verifiers so, that they can efficiently verify the data integrity without retrieving the entire file. It can also perform multiple auditing tasks simultaneously. Keywords: Cloud Security, Privacy Preserving , MA-ABE, Cloud Auditing, Anonymization.
