基于二维码技术的学习资源管理系统的设计与实现

Design and Implementation of Learning Resource Management System Based on Two Dimensional Code Technology

本文针对大量的多媒体学习资源,快速查找对应的学习资源相对繁琐,由于二维码技术日臻成熟,并且讨论了二维码技术运用在多媒体学习资源中的可行性,将二维码技术与多媒体学习资源结合运用到立体化教材建设中,在实际运用二维码时,由于QR码容易被攻击,因此采用矩阵式二维码中的QR码,并结合信息加密技术RC4加解密算法,保证二维码信息的安全保密性。设计并实现一个应用二维码技术的学习资源管理系统,包括学习资源管理系统和二维码扫描子系统,主要分为PC端编码模块的和Android手机端解码模块。实践表明,二维码运用在系统具有明显的优势,在学习资源管理中使用二维码提高了管理和使用的效率。

This paper aims at a large number of multimedia learning resources, quick search for the corresponding learning resources is relatively cumbersome, as the two-dimensional code technology matures, and discusses the feasibility of using two-dimensional code technology in multimedia learning resources, the combination of two-dimensional code technology and multimedia learning resources is applied to the construction of three-dimensional teaching materials. In practice, QR code is easy to be attacked, so QR code in matrix two-dimensional code is adopted, and RC4 encryption and decryption algorithm is combined to ensure the security of two-dimensional code information. Design and implement a learning resource management system using two-dimensional code technology, including learning resource management system and two-dimensional code scanning subsystem, mainly divided into PC-side encoding module and Android phone-side decoding module. Practice shows that the use of two-dimensional code in the system has obvious advantages in the use of two-dimensional learning resources management to improve the management and use of efficiency.
