Orientation Independent Cell Phone Based Gait Authentication


Gait authentication using a cell phone based accelerometer sensor offers an unobtrusive, user-friendly, and periodicway of authenticating individuals on their cell phones. Inthis study, we present an approach to deal with inevitableerrors induced by continuously changing sensor orientationand other noise under a realistic scenario (when the phoneis placed inside the trouser pockets and the user is walking)by using the magnitude data of tri-axes accelerometer andwavelet based noise elimination modules. This study utilizesa gait data set of 35 participants collected at their respective normal walking pace in two different sessions with anaverage gap of 25 days between the sessions.
