Distributed Secure Storage System Using TPA and The Blockchain

With the fast growth and development of cloud computing technology, grabs the more users nad requires big storage of data in the available storage. This integrity meeting the performance requirements has become a important research area among various academic and research community. Provable Data Ownership (PDP) based on Trusted Party Auditor (TPA) is an important method to solve the big data and storage issues. The recent emergence of decentralized storage based on block-chain technology become the most easy way to prove the ownership of given data. However, it does not seamlessly connect to powerful cloud storage. In this paper, we propose a PDP model based on blockchain and TPA (BTPDP).Based on this, a distributed secure file system (FS) is implemented to achieve his BTPDP authentication of large amounts of electronic data.
