Cloud service providers offer cost-effective, scalable data storage for a fraction of the cost of alternatives. Cloud resources are often shared by a large number of people, but they are also dynamically reallocated based on demand. Due to human error and hardware/software problems, cloud data integrity is questionable. Several methods have been developed by data holders and public verifiers to effectively verify the integrity of cloud data without retrieving all of the data from the cloud server. However, using these current methods, the general public may check the integrity of shared data. This technique for protecting privacy allows for a batch audit of cloud-stored common data. Using group signatures to ensure shared data correctness while calculating metadata. The identity of private information is unknown to public verifiers. Public verifiers in each shared data block preserve the identity of the signer using this privacy method. This protects the sensitive user data very well. Cloud storage audits may be loaded using this technique with ease, and it is also very cost-efficient and effective in its auditing.
