SECURE PRIVACY PRESERVING BATCH AUDITING MECHANISM IN CLOUD STORAGE

There is a need to create an efficient public auditing protocol that gets around the shortcomings of the current auditing system. The suggested solution is designed to allow TPA to regularly or on- demandly verify the accuracy of cloud data without having to download the complete database or place an additional online strain on cloud users or cloud servers. It ensures that no data material during the auditing process is disclosed to TPA. It preserves the secrecy, integrity, and accuracy of stored data. The data owner, cloud server storage, and TPA are the three fundamental components of the proposed approach. The user or data owner is in charge of dividing the file into blocks, using the AES algorithm to encrypt them, producing an MD-5 hash value for each, concatenating hashes, and creating an AES signature on it. The encrypted file blocks are kept on the cloud server.
