Blockchain-Based Security Solutions for Ensuring Data Integrity and Privacy in Big Data Systems

Abstract

The reason why conventional forms of security fail to address the issues of fluctuating big data systems space adequately. Instead, the use of blockchain technology which is a decentralized and entirely transparent and unalterable can provide a proper solution toward these problems. Based on the above Introduction, this paper aims at discussing the application of implementing blockchain security in big data systems. In other words, if data is stored using blockchain, it is very easy to prove as to whether the data has been manipulated or not. Due to the distributed nature of the blockchain, there is also a consideration of the fact that it eliminates the possibility of having single points of failure as a weakness for big data systems. In addition, smart contracts on the blockchain platform can fulfill and enforce data governance policies and regulatory compliance. This paper also presents an analysis of the state of the art of the existing blockchain-based security solutions, their strengths and weaknesses and a vision of the opportunities for further research. The combination of aspects of blockchain technology and big data systems means the possibility of radical changes to data processing to heighten confidence and security in the processing of valuable and security-sensitive data.
