Abstract:

Data Deduplication is a technique of reducing the storage space of data by eliminating the duplicate copies of the data. To maintain the security of data while duplicate check of encryption techniques is proposed. The existing deduplication technique uses a file level deduplication technique which is not in efficient manner for identifying and removing the identical files. In the proposed system block level data deduplication techniques for hashing the content of the file and to find the duplication. Hash based Message Authentication Code (HMAC) for hashing the data. For specialized user the duplicate files can be uploaded normally, but for normal users duplicated files can be uploaded by using the key generated by the admin. The proposed authorized duplicate check scheme incurs minimal overhead compared to normal operations..
