Proof of ownership in deduplicated cloud storage with mobile device efficiency - 2015
Cloud storage such as Dropbox and Bitcasa is one among the most in style cloud services. Currently, with the prevalence of mobile cloud computing, users will even collaboratively edit the latest version of documents and synchronize the newest files on their smart mobile devices. A remarkable feature of current cloud storage is its virtually infinite storage. To support unlimited storage, the cloud storage supplier uses data deduplication techniques to cut back the information to be stored and so scale back the storage expense. Moreover, the use of knowledge deduplication additionally helps significantly scale back the requirement for bandwidth and thus improve the user experience. Nevertheless, despite the on top of advantages, information deduplication has its inherent security weaknesses. Among them, the most severe is that the adversary could have an unauthorized file downloading via the file hash only. In this text we initial review the previous solutions and establish their performance weaknesses. Then we have a tendency to propose another design that achieves cloud server potency and especially mobile device potency.
