Abstract: The most popular behavioural biometrics that is currently being considered as a second factor of authentication is keystroke dynamics. However, the adoption of this authentication technology faces several challenges, such as lack of a standard benchmark and evaluation methodology that could be used to compare the accuracy and performance of different frameworks. In this paper, we provide a comprehensive design space exploration of various machine learning frameworks to authenticate users based on keystroke dynamics. The paper also studies the machine learning design flow, discusses details of every single step in the process, and provides comparative analysis of possible options available for developers. The paper presents a comparative analysis of various machine learning frameworks supported by experimental analysis. Our experimental work analyses the efficiency of various machine algorithms, compares the impact of filter-based and wrapper-based feature selection techniques, and compares the accuracy of machine learning classifiers by using different feature sets.
