Privacy Preserved Public Auditing for Distributed Data
Abstract: With distributed services strategy, it is commonplace for data to be not only stored in the server, but also shared across multiple users. However, public auditing for such shared data while preserving identity privacy remains to be an open challenge. In this paper, propose a privacy-preserved auditing on shared data stored in the distributed storage. In particular, exploit cryptographic signatures to compute the verification information needed to audit the integrity of shared data. With this mechanism, the identity of the signer in shared data is kept private from a third party auditor (TPA), who is still able to publicly verify the integrity of shared data. Experimental results can demonstrate the effectiveness and efficiency of the proposed mechanism when auditing shared data.
