Attribute Based Storage Mechanism with De-duplication Filter: A Review Paper

Cloud computing relies on sharing of resources to achieve coherence and economy of scale, similar to a utility. In existing system ABE (attribute based encryption) is used to maintain security. Attribute-based encryption is a type of public-key encryption in which the secret key of a user and the cipher-text are dependent upon attributes. In computing, data de-duplication is a specialized data compression technique for eliminating duplicate copies of repeating data. Related and somewhat synonymous terms are intelligent compression and single-instance storage. In this paper we studied the different attribute storage mechanisms as well as de-duplication system.
