Ensuring Data Integrity: Towards a Blockchain-Based Platform to Share the Datasets

In the case of sharing the datasets, the central authority-based storage has depended solely on extensive capacity of suppliers, who actually act as trusted third parties to exchange and store information. This model represents various issues, including information accessibility and data security. The blockchain is able to maintain transaction without central authority. It is an imaginative innovation that opened ways to new applications for tackling various issues in distributed environment. The primary objective of this chapter is to ensure the data integrity of publicly shared datasets for researchers. To achieve this goal, a decentralized blockchain-based architecture has been proposed in this study. A theoretical foundation has been broadly discussed and debated to establish the effectiveness of the proposed architecture. To ensure data security and integrity, the SHA256 hash function and asymmetric encryption algorithm are used. Also, a combination of consortium and public blockchain technology is utilized. This study leads to the base of developing a secure data sharing platform.
