Keystroke-Based Biometric Authentication in Mobile Devices

This paper presents a model for biometric authentication of users based on dynamic typing (keystroke) in mobile devices. In our model, the user accesses the system by typing a string (password) that is monitored in real time. The model captures the time needed for the user to press and release the keys when he is typing and we compare this information with those previously stored into the model. If the result is the same as registered, the user is considered authentic and has access to the system, otherwise the user is regarded as an impostor and has its access blocked by the system. Apos a realizacao de todo o experimento usando o metodo da distancia euclidiana foi possivel chegar a uma taxa de. After performing the experiment using the method of Euclidean distance we reached a FAR = 12,97% and FRR = 2,25%.
