This work investigates how context should be taken into account when conducting continuous authentication of a smartphone user based on touchscreen and accelerometer readings from swipe gestures. The study is based on publicly open data set consisting of 100 study subjects performing pre-defined reading and navigation tasks while sitting or walking. It is shown that context-specific models are needed for different smartphone usage and human activity scenarios to minimize authentication error. Also, the experimental results suggests that utilization of phone movement improves swipe gesture-based verification performance only when the user is moving.
