Today smartphones are becoming widely used as multipurpose devices. If smartphone was stolen, the risks of leaking personal information and abusing it are increased. As a security measure for smartphone, we have considered keystroke dynamics in free text input. Many examinations of keystroke dynamics are applied to QWERTY keyboards and some of the keystroke event times are extracted as feature measurements. In this paper, we adopt the smartphone and extract new feature measurements given by smartphone’s sensors. We propose keystroke dynamics on the feature data in flick inputting of free text. The experiment is performed on twenty-one participants, considering four feature measurements. As a result, it turned out that the recognition accuracy is 96 %, false rejection rate (FRR) is 2 %, and false acceptance rate (FAR) is 0.85 % for 100 hiragana letters input. |
