Abstract
We propose a method of authenticating an examinee by using answers written by the examinee on a pen tablet, to address the problem that it is easy to impersonate someone taking an examination by e-testing over the Internet, and have evaluated the validity of the method. First of all, we confirmed by experiments that a localized arc pattern method for identifying a writer from characters written on paper can be applied to characters written on a pen tablet. We also propose a press localized arc pattern method that incorporates pen pressures that can be acquired from the pen tablet, and have confirmed its validity by experiments. We applied the proposed method to answers given when examinees take an examination by e-testing, not just by character input, and evaluated the validity of the method. As a result, the proposed method judged that the examinee was the authorized examinee 86.1% of the time, with a 3.3% error rate in which another examinee was judged to be the authorized examinee. From this, it is clear that the proposed press localized arc pattern method has validity in examinee authentication.
