摘要：Data de-duplication is one of the most important technique used for removing the identical copies ofrepeating data and it is used in the cloud storage for the purpose of reduce the storage space. Here only one copy foreach file store. These files are owned by huge number of users. Keeping the multiple data copies with similar contentde-duplication eliminates redundant data by keeping only one physical copy and refer other redundant data to that copy.Data de-duplication can be file level or block level. The duplicate copies of identical file eliminates by file level deduplication.And block level de-duplication eliminates duplicate blocks of data that occur in non-identical files. In dede-duplication storage space and bandwidth is reduced but reliability. This paper mainly concentrates on reducingstorage while improving reliability, integrity and privacy of user’s sensitive data. File is divided into fragments usingSecrete Sharing Scheme. This system allocates the file fragments using T-colouring graph technique. T.-Colouringallows to store the nodes at certain distance so prevents attacks like guessing location of fragments. To maintainintegrity we are providing the Third Party Auditor scheme which makes the audit of file stored at cloud and notifies thedata owner about file status stored at cloud server. This system supports security challenges such as authorizedduplicate check, integrity, data confidentiality and reliability.
