Lot of efforts and struggle has been done by the storage administrators to handle the spiraling data like images, audios and videos. Among different data present, images are the stringent data which has to be taken care regarding storage. Most of cloud storage servers demand high cost for storage and also burden backup efficiency. Cloud storage being cost effective have more chance of storing the duplicate images. Instead of finding ways to store multiple copies of data, removal of duplicate data can be achieved by using a technology called data deduplication. Data Deduplication is one of the most popular emerging methods which ensure the storage efficiency by removing the redundant data and storing the unique data only. On the other hand, while storing the valuable image into the centralized server it is necessary to authorize the data being uploaded. This authorization of uploaded data can be accomplished by decentralized system called Blockchain, using which one can authorize the data uploaded and claim for the ownership of the data, thus providing the copyrights of the user. Here in this paper, data deduplication is integrated with Blockchain and implemented which makes the image storage efficient, effective and more secured.
