This study focuses on countermeasures against spoofing. Previous studies have confirmed that personal authentication, using handwriting information, is possible in e-Testing. However, they could only be applied to e-Testing in which the answer is given in one digit (0-9) because the authentication was performed using one digit. This study created an e-Testing system that answers 2-6 digits and proposed a writing authentication method using sequential characters in e-Testing with help of a pen-tablet PC. The experiment yielded that when authenticating with two characters (bigrams) instead of one character (unigrams), the accuracy was higher. Furthermore, it was confirmed that personal authentication is possible even in e-Testing that answers two digits or more.
