Deduplication based storage and retrieval of data from cloud environment

Cloud computing is based on the concept of Internet which enables centralized data storage. Cloud computing poses great possibilities and challenges. Among all the challenges data security the very important issue to be addressed. This paper proposes a novel system for the secure access and storage of the data based on data deduplication and Ramp Secure Secret key (RSS key). The data deduplication saves storage space by eliminating the redundant data and RSS key could enhance data security. This proposed system is better than the current cloud security systems as it addresses and satisfies the key disadvantages of the existing systems.
