Since cloud computing has been driving attention of large number of users for storing their important data, data compression technique managing data stored over cloud had become huge necessity. Task of data deduplication technique is to remove duplicate copies of data on a server and keep only one physical copy. Duplicate copies over cloud are identified by generating tags from content of data copy and matching them with tags of files already residing over cloud. Duplicate copies will correspond to same tags generated using MD5 hashing technique. To maintain security of data, it is encrypted using linear congruentiality algorithm before uploading over cloud which employs convergent encryption concept. To encrypt data, convergent keys are derived from content of data using SHA-512 hashing technique and data is encrypted using this key according to convergent encryption concept which requires key derived from content of data.
