基于区块链技术的高校物理数字化教育资源集成共享方法

Integration and Sharing Method of Physical Digital Education Resources in Universities Based on Blockchain Technology

教育资源自身的重叠性,导致资源集成共享阶段的冗余难以控制,为此提出基于区块链技术的高校物理数字化教育资源集成共享方法。将物理数字化教育资源转换为特定格式——可携带文件格式(Portable Document Format,PDF)后,通过封装处理(添加元数据、内容摘要信息),使其形成一个完整的资源区块,并生成唯一的哈希值,标识对应的资源,上传至区块链网络中;最后利用内容信息认定方式,通过资源内容相似度检测,比较区块链上的相似资源。在测试结果中,集成资源的覆盖率最高,始终稳定在97.0%以上,对应的集成资源规模也始终低于对照组,实现了对冗余的有效控制。

Due to the overlap of educational resources themselves,it is difficult to control the redundancy in the integration and sharing stage.Therefore,the integration and sharing method of physical digital educational resources in universities based on blockchain technology is put forward.After the physical digital education resources are converted into a specific format Portable Document Format(PDF),a complete resource block is formed by packaging processing(adding metadata and content summary information),and a unique hash value is generated,identifying the corresponding resources and uploaded to the blockchain network.Finally,the content information identification method is used to compare the similarity resources on the blockchain through the similarity detection of resource content.In the test results,the coverage rate of integrated resources was the highest,always stable above 97.0%,and the corresponding scale of integrated resources was always lower than that of the control group,realizing the effective control of redundancy.
