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

电子考试可以不受时间和地点的限制自由进行。我已经开发出一种方法来验证考生，而测试正在进行。这项研究的重点是这样一个事实，即许多测试格式涉及写出答案。因此，采用平板电脑输入书面答案。该模型通过结合笔压、xy坐标、书写方向角和上升垂直角等动态书写数据对考生进行身份认证。此外，书写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.
