User Authentication with GRU based Siamese Networks using Keyboard Usage Behaviour

In this study, we will examine user’s keyboard usage behavior, the features extracted from the user’s timing data during a short-fixed text entries will be converted into images and fed into a Gated Recurrent Unit (GRU) in a new Siamese Network topology will be proposed. The results will be examined within the scope of group leakage, and a new leakage-free method will be proposed and evaluated.
