Cloud computing technique which is most widely used today.In that clouding is done over large communication network like internet and provide large storage space in all sector like government agency ,private enterprises etc and also store personal data on cloud.But the most important problem in cloud is that large amount of storage space is required and also duplicate copies of data is store on cloud .There are many techniques which is used for eliminating duplicate copies of repeating data .From that one of the important technique is data deduplication . Data de-duplication is specialized data compression techniques for removing duplicate copies of repeating data and has been widely used in cloud storage to reduce the amount of storage space and save bandwidth. To protect the confidentiality of sensitive data on cloud , the convergent encryption technique is used to encrypt the data before outsourcing . In proposed system used secrete sharing scheme.In that files are divided into number of blocks called as shares and this shares store on the different number of nodes.By using recover technique number of shares are combine into single file. That means using this scheme provide data security,confidentialty ,data reliability.
