On e-Testing, it is necessary to prevent impersonation to ensure fairness.
There are researches that the examinee authentication method to prevent the spoofing using writing data taken by pen tablet.
In these researches, a method with sub-stroke was proposed.
This method is independent on the form of the characters and it means that the examinee can be authenticate on the short-answer examination, and an evaluation result suggested the possibility of authentication of characters (kanji) mainly on straight lines by this method.
In this paper, we examined an authentication procedure which allows to compare among different characters contain curve strokes. We applied codebook and chaincode proposed in related work to examinee authentication. From the result of an evaluation experiment, it was suggested that codebook and local chaincode features are effective features for writer authentication of different characters. |
