In storage services with massive info, the storage servers may need to cut back the number of keep info, associate degreed additionally the patrons may need to look at the integrity of their info with an occasional worth, since the worth of the functions related to info storage increase in proportion to the scale of the data. to achieve these goals, secure deduplication and integrity auditing delegation techniques are studied, which could deflate the number of data confine storage by eliminating duplicated copies and permit shoppers to with efficiency verify the integrity of keep files by authorisation dear operations to a honorable party, severally. to the current purpose many studies ar conducted on each topic, separately, whereas relatively few combined schemes, that supports the two functions at constant time, ar researched. during this paper, we've an inclination to vogue a combined technique that performs every secure deduplication of encrypted info and public integrity auditing of data. To support the two functions, the projected theme performs challenge response protocols victimization the BLS signature based homomorphic linear critic. we have a tendency to utilize a third party auditor for taking part in public audit, therefore on assist impotent shoppers. The projected theme satisfies all the basic security requirements. we've an inclination to in addition propose a pair of variances that offer higher security and higher performance.
