基于Office Open XML技术的机考作弊检测方法探究——以全国计算机等级考试为例

A Study on Computer-based Test Cheating Detection Based on Office Open XML File Formats

基于真实环境的MS Office计算机化考试提升了考试的友好性,但也带来基于文件复制或内容复制的考试作弊安全隐患,需要研究新方法对此类作弊进行检测。通过分析Office Open XML文档部件中的相关参数,提出复制类作弊的检测方法,并以全国计算机等级考试的Word试题为例进行检验。研究结果表明,该方法能直接、有效地判断基于文件复制的作弊,对大部分基于内容复制的作弊也能进行有效判断,但也存在个别无法判断的情况,需要结合其他参数综合分析。

Based on real environment,the MS Office exam makes itself more user-friendly,but it also brings about the security risk of cheating on test in copying document or content.Therefore,new methods are needed to detect such kind of cheating.By analyzing the relevant parameters in the Office Open XML document components,this study proposed a detection method of copying cheating,and conducted a validation process by taking a Microsoft Word item from National Computer Rank Examination as an example.The result shows that this method can make direct and effective judgments on all document-copying cheating as well as the majority of content-copying cheating.For some individual cases that cannot be judged by this method,we need to make more comprehensive analysis together with other parameters.
