摘要：Attribute based encryption (ABE) has been widely used in cloud computing where a data provider
outsources his/her encrypted due to a cloud service provider and can share the data with user possessing specific
credentials or attributes. Standard ABE System does not support secure de duplication which crucial for eliminating
duplicates copies of identical data in order to save storage space In this paper present an attributes based storage
detection and public cloud manager the storage. Compared with prior data De duplication the main two advantages is it
can be used to confidentially share data with user by specifying access policies rather than sharing decryption key. And
secondly it achieves the standard notion of semantic security for data confidentiality. In Advances the Modify a cipher
text over one access policy into cipher text of same plaintext but under other access policies.
