| Abstract(in English) | Since the common examinee authentication method in Web-testing is based only on the ID and password at the beginning of the test, it is easy to spoof during the test. To solve this problem, we proposed an examinee authentication method based on online feature values such as pen pressure and pen tilt when the examinee wrote the answer characters on a tablet PC. However, the accuracy of our previous research was insufficient. Hence, it was practically difficult to apply the examinee authentication method of previous research to Web-testing. One reason for this is because linear regression was used to combine multiple features. In this research, we constructed a handwriting authentication model using MLP for distance coupling. In addition, we applied SMOTE to adjust the imbalanced data with positive and negative cases. As a result, the accuracy of the authentication has improved compared to our previous research. Therefore, the effectiveness of the proposed method using MLP and SMOTE was confirmed. |
