Towards A Blockchain Based Platform to Share the Datasets

Abstract

Conventional cloud or central authority based storage has depended solely on extensive capacity suppliers, who act as trusted third parties to exchange and store information. This model represents various issues including information accessibility, high operational expense, and data security. The blockchain is able to maintain transaction without a central authority, the blockchain is an imaginative innovation which opened ways to new applications for tackling various issues in the distributed environment. The primary objectives in this thesis creating secure data sharing platform where the data provider will share their research related data that the verified researcher can use by downloading and contribute to further research. This thesis considers the future prospects of blockchain technology and cryptographic ability in data storage. In this thesis, we proposed an architecture that leverage blockchain technology and provide secure data storage. The data provider shares their data into consortium blockchain network that consist of plaintext and encrypted form the same plaintext hash value via data provider private key (digital signature) and after completion the validating process then the encrypted data will be broadcast into public blockchain network and finally the data requester could request for their desired data via joining the public blockchain network. We have been trying to analysis our proposed architecture performance via comparison among existing blockchain based data storage and traditional database system
