Privacy Risk and Correction Mechanism of Higher Education Mooc Based on Blockchain Technology in the Era of Big Data

Abstract

The emergence of Massive Online Open Course (MOOC) has sparked a digital tsunami globally, bringing a huge impact on higher education. The open curriculum format of MOOC has achieved the optimal transmission of top teaching resources and personalized teaching based on different groups, which is different from traditional teaching models. At the same time, in the process of implementing educational activities, the MOOC platform based on big data mining will bring a certain degree of privacy risk due to improper data collection, storage, or processing. The traditional MOOC have not achieved as much as they should. The main problem is that fully centralized online education cannot solve the trust problem. The emergence of blockchain technology solves the problem of lack of trust, but the open and transparent mechanism of blockchain also introduces a new problem, that is, the privacy of user data can not be reasonably protected.
