Abstract:

In this paper, we propose a novel biometrics based system to achieve continuous and unobservable re-authentication for smartphones. Our system uses a classifier to learn the owner’s finger movement patterns and checks the current user’s finger movement patterns against the owner’s. Experiments show that our system is efficient on smartphones and achieves high accuracy.
