Data deduplication is an effective compression tech-nique to eliminate duplicate copies of repeating data.It has been widely used in cloud storage to reduce the amount of storage space and save bandwidth. For the protection of sensitive data while supporting deduplication, the convergent encryption technique is being used to encrypt the data before outsourcing it to cloud storage.In order to make system more secure, the different privileges of users are again considered while checking duplicate content.But the problem which occurs in this approch is that int this we use symmetric key encryption technique to encryts and decrypts data.In this only single key is used for encryption and dycryption , This key can be misused. So we are using public key cyptography method in this approch the file is encrypted by using public key and drypted by using private key this two different keys are generated on private cloud.
