D Asha, D Nagaraj 03 04 Today cloud storage systems have huge issues with the process of securely erasing duplicate data and verifying the integrity of data fast and accurately It is particularly so when active processes such as the addition or removal of blocks are taken into consideration The traditional compression requires a lot of additional computing power since whole files must be reencrypted and verified each time the data is modified To bypass these issues DIADD introduces a deduplication and data integrity check safe system which is compatible with changing data The scheme allows the owners of data to transmit encrypted data to other parties besides generating unique file tags through a multiset hash facility This will ensure that future users do not end up uploading the same information twice through proof of ownership methods Using hashbased authenticators integrity checks are given to a TPA These authenticators are only used to verify the modified blocks rather than the entire file which reduces communication and computing expenses It is also equipped with a safe and searchable trapdoor that allows you to search keywords in encrypted files stored in the cloud without revealing any information about you The system also ensures that the storage process is efficient the data operations are facilitated dynamically data integrity is ensured and privacy ensured when searching It offers a safe and scalable method of outsourcing data management in clouds Copyright (c) Journal of Science Engineering Technology and Management Science.
