Gesture-based User Authentication on Mobile Devices using Accelerometer and Gyroscope

Dennis Guse, Sven Kratz, Niklas Kirschnick, Sebastian Möller Mobile HCI 2011

Abstract: In this paper we present a gesture-based user authentication mechanism for handheld mobile devices. For authentication the user does not enter a password or PIN, but rather moves the device in an individual specific manner. The mobile device measures the movements using a built-in 3D-accelerometer and a 3D-gyroscope. Movement-based biometric features for authentication are considered very useful, because they are memorized differently and especially promising for mobile devices. The implemented mechanism was evaluated in a user study with regard to feasibility, the user perception and security including active attacks.
