Abstract
With cloud computing and data storage services, the data not only stored in the cloud but it can be shared among multiple users in the cloud. However the integrity of the shared cloud data protection is formidable task due to the hardware, software failures and human errors. For secure purpose to introduce an effective TPA to perform public auditing for the shared data is very importance, so that the users can be worry free of the outsourced data. While auditing the integrity of the shared data will inevitably reveal confidential information, identity privacy to the public verifiers (TPA). In this paper we propose a secure cloud storage system to ensure that the shared data integrity can be checked publicly, group users in the shared data need to generate signatures on all the blocks in shared data performed by different users. Especially, we utilize ring signatures to calculate the authentication information needed to audit the integrity of shared data. By using Public Auditing, the identity of the signer on each block in shared data is reserved private from a third party auditor (TPA), who is still able to verify the integrity of shared data without retrieving the entire file. Using Hash Based Verification, we can also provide traceability about the shared data.
