Keystroke dynamics-based user authentication by Japanese old poems

Needless to say, computer systems should be more secure for our safe life and society nowadays. A keystroke dynamics-based user authentication is known as one of potentially valid biometrics. In our previous research, input text requiring about two hundred keystrokes provides less than 1% EER, Equal Error Rate, for fifty-one subjects. To improve data input situation, this paper deals with one third shorter texts. Those texts are Japanese old poems composed of 5-7-5-7-7 syllabaries. We have asked thirty-five subjects to type these poems requiring about sixty keystrokes each three times. By user authentication experiments, we have achieved around EER 4 to 7%.
