Personal Information Protection Based on Blockchain Technology

Abstract

Blockchain technology has evolved from Bitcoin to fields such as securities trading, online payments, logistics, and healthcare. On this basis, due to the continuous development and popularization of blockchain technology, the privacy issues involved have become increasingly prominent. This article first provides a detailed introduction to the background and research significance of this topic and investigates the current situation of personal information leakage. Through information leakage cases, the reasons for information leakage were analyzed. Secondly, we evaluated the level of awareness and understanding among WeChat users of blockchain technology, as well as their understanding of the potential application of blockchain technology in personal information protection, as well as their views on the feasibility and credibility of the technology. This includes an evaluation of the security, privacy protection ability, availability, and other aspects of the solution to understand the user's recognition and acceptance of the solution. Based on the research findings, it can be concluded that Tenpay collects WeChat payment record information, the payment function collects bank card-related information, user age, and collects voice to text conversion information but does not save it, which has the strongest impact on WeChat user satisfaction with personal information protection. An investigation into the reasons for personal information leakage among WeChat users, the proportion of information leakage, and the remedial measures taken for information leakage. Finally, based on the current situation of personal information leakage among WeChat users, this article proposes suggestions and solutions for improvement based on blockchain technology. The results show that WeChat users' awareness and satisfaction with blockchain technology can better achieve data security and feasibility. Through verification, the advantages of blockchain application in personal information protection can be better confirmed, which has broad prospects for the application of blockchain technology in personal information protection.
