The constant and endless data storing on cloud has been persuaded speedily since past few years and this leaded to deal with storage problems on cloud. To overcome this problem, a popular deduplication technique is being used in the cloud which lessens to save a same copy of data multiple times which is referred to as data redundancy. But this technique, apart from reducing burden on cloud, has many flaws for data confidentiality and cloud service users privacy. This project addresses the problems of authorized data deduplication and deals with all those flaws, introducing the convergent encryption technique which encrypts the data better using hash values of each data content for privacy purposes. The project also present several new deduplication constructions supporting authorized duplicate check in a hybrid cloud architecture. The security purposes of data is fully accomplished in deduplication with this proposal. For the demonstration purposes, a prototype is implemented for the proposed authorized duplicate check scheme and conducts an experiment which proves the encryption proposal for data security. This can be performed on a very large scale which will validate it in a better manner.
