They used statistical pattern recognition for touch-based authentication. | |||
This is more than circuits, passwords, pins, swipe, etc, they were looking for patterns of use during regular mobile device activity. Touch data comes from many operations and many apps. | |||
They did a 21 day study examining universiality, collectability, distinctness and permanence of touch biometrics. | |||
Permanence was low: not stable matching over time since people change their use patterns, have sore hands, moods change, etc. | |||
To get over permanence change, they continued training the model while it was in use and that was more stable. | |||
