A Blockchain-based Untact Education...(Elementary Education Online, 2021.02) > 자유게시판

Abstract 

With the advent of the post-COVID-19 era, the existing educational environment is at the point

of transition to an untact-based educational environment. The current online education system has a limitation in safely providing the untact education system. We proposed an untact education system based on blockchain. Through the proposed method, learning contents and results can be safely stored in the blockchain. In addition, integrity damage due to data manipulation can be prevented. In particular, the efficiency of learning can be improved through behavioral analysis in the learning process, and the privacy of learners is protected by masking face recognition data. In the untact education environment, privacy exposure to learners may occur, and various information such as facial recognition data and test evaluation data may be exposed. Blockchain can safely protect against these vulnerabilities. As an advantage of the proposed method, the teacher can take appropriate action by grasping the learner's concentration through real-time behavior analysis. It also generates warnings when learners take inappropriate actions. These advantages increase the efficiency of untact education by enabling timely education.
