	abstract = {We introduce the notion of implicit authentication - the ability to authenticate mobile users based on actions they would carry out anyway. We develop a model for how to perform implicit authentication, and describe experiments aimed at assessing the benefits of our techniques. Our preliminary findings support that this is a meaningful approach, whether used to increase usability or increase security.},
