Delegating Public Auditing and Invigorate Data Storage in Public Cloud

Abstract

In cloud computing the data owners will use storage service to outsource their sensitive data and whenever they need they can download from the cloud but due to the privacy challenges protecting data from outside or inside attacks will leads to problem to the data owner. In order to check remote data the data owner need to verify the data periodically and if any failures or modifications identified, then he has to remove old data and he has to upload new data to the cloud this will leads to the burden on the data owner and if data owner use PDP (Provable Data Possession) model it will audit in single server. To overcome the problems and to remove burden on the data owner, in this paper we are proposing MBR (Minimum Bandwidth re-generating codes) and MSR (Minimum storage regenerating code) to securely repairing the block in cloud.
