چکیده
IJRAET Abstract— To eliminate duplicate copies of data we use data de-duplication process. As well as it is used in cloud storage to minimize memory space and upload bandwidth only one copy for every file stored in cloud that can be used by more number of users. Deduplication process helps to improve storage space. Another challenge of privacy for sensitive data also arises. The aim of this paper is to create the primary attempt formalize the concept of distributed reliable deduplication system. In our proposed system we are planning to develop new distributed de-duplication systems that are highly reliable. In de-duplication method data chunks are distributed across multiple cloud servers rather than using convergent encoding as in previous de-duplication systems we use deterministic secret sharing scheme in distributed storage systems. So we can reach the required concepts for security that are data privacy and tag reference in the proposed security model, Security analysis express that our deduplication systems are secure. Index Terms−System model, Secure-Cloud Storage Provider, Data De-duplication, Secret Sharing, Filelevel De-duplication, Block-level De-duplication INTRODUCTION In our proposed system we are aiming to use data deduplication process. Initial we should know what is data de-duplication, it reduces the quantity of data that has to be physically stored by eliminating extra data and replacing when repetition of it with a reference to the original. In data de-duplication we remove unwanted copy of data and save the memory area. With the use of de-duplication method reliability is improved moreover because it avoids wastage of memory space .Secure means that in our system we use encryption and decryption techniques. Encryption means that convert plane text into encoded text this techniques known as an encryption. This encoded text is transfer to server CS1, CS2, CS3. Again this encoded text is converted into plane text referred to as decryption techniques. Distributed means that we create server CS2,CS2,CS3 from this server user select any one, from server choice data was distributed data de-duplication means delete duplicate copy in which use two techniques initial one is Cloud Based Data Deduplication with Secure Reliability
