    Continuous authentication using mouse dynamics
    (BIOSIG 2013, 2013) Mondal, Soumik; Bours, Patrick
    In this paper, we demonstrate a new way to perform continuous authentication using Mouse Dynamics as the behavioural biometric modality. In the proposed scheme, the user will be authenticated per mouse event performed on his/her system. We have used a publicly available mouse dynamics dataset and extracted per event features suitable for the proposed scheme. In this research, we have used the mouse dynamics data of 49 users and evaluated the system performance with 6 machine learning algorithms. In this approach, the genuine user has never been classified as an impostor throughout a full session whereas the average number of mouse actions an impostor could perform before detection is 94 from the best classification algorithm with a person based threshold.

    Does context matter for the performance of continuous authentication biometric systems? an empirical study on mobile devices
    (BIOSIG 2015, 2015) Mondal, Soumik; Bours, Patrick
    In this paper we will show that context has an influence on the performance of a continuous authentication system. When context is considered we notice that the performance of the system improves by a factor of approximately 3. Even when testing and training are not based on exactly the same task, but on a similar task, we see an improvement of the performance over a system where the context is not included. In fact, we proof that the performance of the system depends on which particular kind of task is used for the training.
