A Survey on Detection Deduplication Encrypted Files in Cloud

ARTICLE INFO Today is the most important issue in cloud computing is duplication for any organization, so we analysis this issue an avoid the reparative files on cloud storage. Avoidance of the file is advantages the cloud size issue. To protect the confidentiality of sensitive data while supporting deduplication, the convergent encryption technique has been proposed to encrypt the data before outsourcing. To better protect data security, on cloud storage. In this system we check the duplicate file on cloud storage also security apply using encryption. We use the AES encryption algorithm for encrypt the file simultaneously we check the duplicate file using the hashing algorithm. Also enhanced this system using recover option, cloud provide the deleted file backup on requesting. This paper study on the plain text as a input the system for checking the duplicate file, we next stage we analysis the encrypted file as a input to the system and find the duplicate file on the cloud storage.
