Secrecy Preserving Public Ascertaining for Cloud Storage Using Digital Signature

Rekha A ^[3] | Padmashree G

Abstract: Cloud is employed not just for storing data, however the stored data will be shared by multiple users. Due to this the integrity of cloud data is subject to doubt. Many mechanisms are designed to support public auditing of shared data stored within the cloud. Throughout auditing, the shared data is kept private from Third party auditor (TPA), who are able to verify shared data integrity using digital signature without downloading or retrieving the whole file. Digital signature is used to assess the verification metadata required to audit the correctness of shared data. With this, the identity of the signer on each block of a file is kept private from auditor. In this paper, we tend to propose the traceability and data freshness in the cloud using digital signatures.
