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
