摘要
成绩管理对于高校管理而言具有十分重大的意义.可以帮助学校更好的整理、统计、分析学生的学习情况.因此,成绩管理系统中信息的真实性和安全性尤为重要.目前的成绩管理系统大多采用中心化的管理方式,依赖于管理员通过SQL Server、Oracle等大型中心化数据库来进行数据管理,中心化平台往往会带来信息的泄露和篡改等问题.随着区块链技术的兴起,其具有的去中心化、去信任化的特性逐渐引起人们的关注.本文利用去中心化的区块链技术,为成绩管理系统提出一个安全、防篡改的管理系统.我们利用P2P网络和区块链技术为系统提供一个安全稳定的运行环境,将学生成绩进行Hash,利用时间戳服务OriginStamp的API将Hash后的结果嵌入区块链中,区块链中的数据受到整个网络的管理和监控,防止随意篡改和破坏.同时为用户和底层数据提供交互界面,完成成绩上传、修改以及查询功能.该方案可以有效的保证成绩管理系统中数据的真实性、有效性,对学校管理学生信息、制定教学任务等有着重大的影响.
Grade management is of great significance for university management. It helps schools to better organize, count, and analyze students＇ learning. Therefore, the authenticity and security of information in the management system is particularly important. Most of the current score management systems use centralized management methods, relying on administrators. to manage data through centralized databases such as SQL Server, Oracle, which have the risk about information leakage and tampering. With the rise of blockchain technology, the decentralized and distrusted features have attracted much attention. By using decentralized blockchain technology to proposes a secure and tamper-proof management system for score management. We use P2 P network and blockchain to provide a safe and stable operating environment for the system,The students＇ grades are hashed,and the results of the hash are embedded in a blockchain using the timestamp service OriginStamp＇s API. The data in the blockchain is managed and monitored by the entire network to prevent illegal tampering and destruction. We provide interactive interfaces for users and the underlying data to complete the uploading, modifying and query functions. The proposed system can effectively provide the authenticity and validity of data in the score management system, and has a significant impact on the management of student information in schools and the formulation of teaching tasks.
