Blockchain Application on Big Data Security

Abstract

In recent years, advances in technology in several industries have resulted in massive data collections on the web. It raises worries about large data security and protection. The advent of Blockchain technology has caused a revolution in the security field for different applications. The distributed ledger is stored on each Blockchain node, which enhances security and data transparency. On the Blockchain network, illegal users are not authorized to undertake any fault transactions. In this article, we will discuss how Blockchain may be employed to secure the big data. We explain the problems that the Blockchain faced with big data and its solutions. We summarize recent works of Blockchain with big data and the present issues and trends. We demonstrate that Blockchain technology is still in its initial phases of validation and there are no large-scale application scenarios available, particularly in the big data sector. Finally, we narrow our study to the Healthcare industry and offer the following research directions for its primary issues.
