Application of blockchain technology for information security in the financial sector

Abstract

This study focuses on the impact of Blockchain Technology on the financial sector, specifically on improving information security. The complexity in the implementation of this technology and the resistance to change on the part of financial institutions that already have established systems are identified as main problems. The objectives of the study include the determination of improvement solutions from Blockchain Technology, the comparison of their applicability in the financial field and the proposal of strategies for their effective implementation. The methodology used consisted of a systematic review of 11 scientific articles collected since 2018. Of these, 82 % used the deductive method as a research approach, while 54 % used technological information as the main sample for their studies. The findings highlighted the relevance of Blockchain in financial markets, emphasizing its consensus mechanisms and its robust focus on information security. A trend was also observed in the use of this technological resource to guarantee the integrity of data in the financial field. In conclusion, it is highlighted that Blockchain Technology offers significant potential to improve security in financial operations. However, it is recognized that its full adoption faces technical challenges, as well as resistance and adaptation from already established institutions in the financial field. Despite these difficulties, there is a growing interest in exploring and developing strategies to effectively incorporate Blockchain Technology in the financial sector, seeking its use and benefit in the face of constant advances in information security.
