Design of a Digital Archive System for Positive Emotions of University Students Based on Blockchain Technology

With the continuous development of society, the mental health of college students has attracted attention for research. In order to better understand and pay attention to the positive emotions of college students, we designed a digital archive system based on blockchain technology. The system is decentralized, untamperable, and transparent and provides a secure, trustworthy, and privacy-protected digital archive storage and sharing mechanism. By collecting college students’ emotional data, the system generates personalized positive emotion profiles and provides advice and support for personalized mental health.
