A Model for Authenticating Examinees and Detecting Abnormal Behavior during e-Testing

电子测试可以在任何时间和地点自由进行。我已经开发了一种方法，可以在考试时验证考生的身份。这项研究的重点是，许多测试形式都需要写出答案。因此，使用平板电脑输入书面答案。该模型结合笔压、xy坐标、书写方向角度、垂直上升角度等动态书写数据，对考生进行身份验证。此外，写作数据能够揭示正常回答所花费的时间与通过查找模型答案所花费的时间之间的差异。

E-tests can be freely taken regardless of time or place. I have developed a method for authenticating the examinee while the test is being taken. This study focuses on the fact that many test formats involve writing out answers. A tablet computer is therefore employed for inputting written answers. The proposed model authenticates the examinee by combining dynamic writing data such as pen pressure, xy coordinates, angle of writing direction, and ascending vertical angle. Furthermore, the writing data are able to reveal differences between the time taken to answer as usual and the time taken to answer by looking up a model answer.
