Leakage Resilient Proofs of Ownership in Cloud Storage
Cloud storage service (e.g Dropbox, Skydrive, Google Drive, iCloud, and Amazon S3) is becoming more and more popular in recent years. The volume of personal or business data stored in cloud storage keeps increasing. In face to the challenge of rapidly growing volume of data in cloud, de-duplication technique is highly demanded to save disk space by removing duplicated copies of the same file (single instance storage). SNIA reported that the de-duplication technique can save up to 90% storage, dependent on applications. Traditional de-duplication technique (i.e. server side de-duplication) in centralized storage system removes duplicated copies residing in the same server.
