Zusammenfassung
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.
