Proposal of Blockchain based New Framework for Multi Clouds
Abstract: The emerging of cloud data sharing can create great values, especially in multi clouds. But, data island between different cloud service providers has drawn trust problem in data sharing, causing contradictions with the increasing sharing need of cloud data users. And how to ensure the data value for both data owner and data user before sharing, is another challenge limiting massive data sharing in the multi clouds. To solve the problems above, I propose a new framework with blockchain to support trustworthy and valuable data sharing. I design namespace - based unique identifier pair to support data description corresponding with data in multi - cloud, and build a blockchain - based data encoding protocol to manage the metadata with identifier pair in the blockchain ledger. To share data in multi - cloud, I build a data parsing protocol with smart contract to query and get the sharing cloud data efficiently. I also build identifier updating protocol to satisfy the dynamicity of data, and data check protocol to ensure the validity of data.
