A Blockchain-Based Scheme for Secure Storage and Sharing of Student Digital Profiles

With the development of education informati-zation in China, the student profiles are becoming digitized. However, currently different digital profiles of a student are still stored dispersedly in multiple databases, which results in information silos and vulnerability to security and privacy threats. Aiming at these deficiencies, this paper proposes a secure storage and sharing scheme of student digital profile based on blockchain technology. With the characteristics of decentralization, security, credibility, and tamper-resistance of the blockchain, the consensus of network nodes is achieved through the Delegated Byzantine Fault Tolerance (DBFT) protocol, and the sharing of student digital profile information is achieved through the access control mechanism. The public information of educational digital information is preserved on the blockchain, and the student profiles are encrypted and stored in a database or cloud, which facilitates the effective storage of personal digital profiles and information sharing among various systems. The proposed scheme utilizes blockchain technology for decentralized and tamper-proof management, and provides a solution to information silos and security issues of student digital profiles.
