Abstract: With a large number of users migrating towards cloud storage for storing their important data, data compression technique managing data stored over cloud had gained much importance. This technique removes duplicate copies of same data on a server and keeps only one copy. Again to protect data from attackers, data is encrypted using the linear congruential algorithm which employs convergent encryption concept. An authorized duplicate check is performed by users after encryption of data with help of generated tags. The file is uploaded if it is not already present otherwise POW is implemented. Hybrid cloud architecture is used with the public and private cloud, where public cloud stores all unique copies of data and private cloud manages authenticated access by maintaining privileges associated with file and users.
