This paper presents a novel method for keystroke dynamics based authentication by utilising Generalised Fuzzy Model (GFM), which is a combination of Mamdani-Larsen and Takagi-Sugeno fuzzy models. We make use of Gaussian Mixture Model (GMM) and GFM for modelling using the individual keystroke measurement types and combinations of measurement types of the keystroke dynamics. To validate GFM on keystroke dynamics in the real-world situation, it is tested on CMU dataset and the performance of this model is superior to that of GMM.
