Continuous User Authentication by the Classification Method Based on the Dynamic Touchscreen Biometrics
Kirill Leyfer, Anton Spivak · 2019
When developing protection mechanisms of the confidential data on mobile devices, a balance of reliability and ease of use must be maintained. Such a balance can be provided by a biometric authentication system, which is quite easy to use while being sufficiently reliable. Introduction of the dynamic biometric and behavioral authentication factors into the system can further improve its reliability keeping the balance. Most smartphones have a touchscreen display, which is proven by the previous studies to be able to capture the dynamic biometric and behavioral characteristics of users' input events. This paper proposes a method of distinguishing a legitimate mobile device user from the intruder by analyzing dynamic biometric and behavioral characteristics of touch screen input events.
