In storage services with large information, the storage servers might want to scale back the amount of keep information, and also the shoppers might want to observe the integrity of their information with an occasional price, since the value of the functions associated with information storage increase in proportion to the size of the info. to attain these goals, secure deduplication and integrity auditing delegation techniques have been studied, which might cut back the amount of information keep in storage by eliminating duplicated copies and allow shoppers to expeditiously verify the integrity of keep files by empowerment pricey operations to a trusty party, severally. to this point several studies are conducted on every topic, separately, whereas comparatively few combined schemes, that supports the 2 functions at the same time, are researched. In this paper, we have a tendency to style a combined technique that performs each secure deduplication of encrypted information and public integrity auditing of information. To support the 2 functions, the projected theme performs challenge response protocols victimization the BLS signature primarily based homomorphic linear critic. We utilize a 3rd party auditor for playing public audit, so as to assist powerless shoppers. The projected theme satisfies all the fundamental security necessities. we have a tendency to additionally propose 2 variances that give higher security and better performance.
