A Blockchain-Based System for Student E-Portfolio Assessment Using Smart Contract

Abstract

Nowadays, as student e-portfolio systems increase in popularity, the large storage space and convenient retrieval of e-portfolio system provide a more efficient way for heavy file management, while the security concerns about personal information and privacy of students arise. The traditional student e-portfolio system adopts a centralized system which caused some problems such as an organization that has full control over the information that could tamper with the database, the insecurity of student e-portfolio. However, blockchain application has mushroomed, providing opportunities for solving the shortcomings proposed above. In this paper, we combine with the fabric blockchain technology to implement student e-portfolio system for permanently recording student growth information, which uses smart contract to realize the registration and authentication of student identity, the portfolio recording and management, the publication of learning evaluation. Finally, we analyze the system compared with traditional system, and the comparative result indicates that the proposed system can not only effectively manage student information, but also protect privacy.
