摘要：Data Storage outsourcing in cloud computing is a rising trend which prompts a number of interestingsecurity issues. Provable data possession (PDP) is a method for ensuring the integrity of data in storage outsourcing.Remote integrity checking is crucial in cloud storage, here using multi cloud. It can help the clients to check theirwhole outsourced data by without downloading. This research addresses the construction of efficient PDP which calledas RSA Based-PDP (RSA-PDP) mechanism for distributed cloud storage to support data migration and scalability ofservice. Uploading data are stored in different blocks in multicloud. The generation of tags with the length irrelevant tothe size of data blocks. To reduce the memory space by using variable length block verification based on hashingalgorithm. Cloud service provider is semi honest server so attacker can easily attack data. Here the data are securedfrom datamining attacker.
