Literature Review on Security of Personal Information in Electronic Payments

With the recent development of e-commerce in recent years, electronic payments, as an emerging payment method, are becoming increasingly prevalent in people's lives. Due to the open nature of the internet, the security of personal information in electronic payments inevitably faces significant challenges within this open network environment. Therefore, the focus of this review is on the research of personal information security in electronic payments, aiming to understand security issues related to individual users in the context of electronic payments. This is a general literature review conducted using the PRISMA systematic literature review method. Through hierarchical screening using the keywords "security" and "information" and "payment", a total of 76 articles related to personal information security in electronic payments were selected. The examination of these 76 papers revealed threats to personal information in electronic payments, including phishing, malicious software, and data breaches. To address these security issues, electronic payment platforms need to implement multi-factor authentication, and biometric technology, and enhance the use of encryption technologies for payment information. As internet technology continues to improve and evolve, an increasing number of users are adopting electronic commerce network payment technologies. In this context, a time-series analysis of the number of electronic payment applications and services or the number of users should be conducted using methods such as Google searches, database searches, and time-series analysis. The study concludes that electronic payments are gradually altering traditional payment methods, making the protection of personal information crucial for users engaging in electronic payment processes.
