EduChain: A Blockchain-Based Privacy-Preserving Lifelong Education Platform

With the popularization of lifelong education, academic and vocational education run through the life of students. However, the traditional lifelong education platform has three problems, namely incoherent achievement data, poor privacy protection, and vulnerability to single-point attacks, which seriously hinder the development of the lifelong education industry. This paper proposes a lifelong education platform based on blockchain supporting privacy protection (EduChain). The access control on achievement data is realized based on proxy re-encryption, and anyone can trace achievement data to the issuing organization through digital signature technology. EduChain can realize the credible transfer and privacy protection of lifelong education archives between students and checkers. The experiments demonstrate the practicality of EduChain in education scenarios.
